一任内、判斷iOS設(shè)備是否安裝了特定的app并跳轉(zhuǎn)

1切蟋、應(yīng)用間相互跳轉(zhuǎn)場(chǎng)景

• 使用第三方用戶登錄强挫，跳轉(zhuǎn)到需授權(quán)的App，還需要返回到調(diào)用的程序牡辽，同時(shí)返回授權(quán)的用戶名粒氧、密碼越除，如QQ登錄，微信登錄等
• 應(yīng)用程序推廣外盯，跳轉(zhuǎn)到另一個(gè)應(yīng)用程序（本機(jī)已經(jīng)安裝）摘盆，或者跳轉(zhuǎn)到APP Store并顯示應(yīng)用程序下載頁(yè)面（本機(jī)沒(méi)有安裝）
• 第三方支付，跳轉(zhuǎn)到第三方支付App饱苟，如支付寶支付孩擂，微信支付
• 內(nèi)容分享，跳轉(zhuǎn)到分享App的對(duì)應(yīng)頁(yè)面箱熬，如分享給微信好友类垦、分享給微信朋友圈狈邑、分享到微博
• 顯示位置、地圖導(dǎo)航蚤认，跳轉(zhuǎn)到地圖應(yīng)用
• 使用系統(tǒng)內(nèi)置程序米苹，跳轉(zhuǎn)到打電話、發(fā)短信砰琢、發(fā)郵件蘸嘶、Safari打開(kāi)網(wǎng)頁(yè)等內(nèi)置App中

2、應(yīng)用間相互跳轉(zhuǎn)實(shí)現(xiàn)原理

URL Schemes

在iOS中打開(kāi)一個(gè)應(yīng)用程序只需要拿到這個(gè)應(yīng)用程序的協(xié)議頭即可陪汽，所以我們只需配置應(yīng)用程序的協(xié)議頭即可亏较。通過(guò)設(shè)置跳轉(zhuǎn)到應(yīng)用B的URL Schemes（自定義的協(xié)議頭），應(yīng)用B將其自身“綁定”到一個(gè)自定義URL Schemes上掩缓，就可以從應(yīng)用A中利用應(yīng)用B的URL Schemes啟動(dòng)應(yīng)用B了雪情。

判斷是否安裝了應(yīng)用

知道app的URL Schemes可以使用openUrl來(lái)獲取iOS是否安裝了某款軟件，比如這樣[[UIApplication sharedApplication] canOpenURL:@"damon://"]你辣，會(huì)返回一個(gè)bool值巡通，為true則安裝了，否則沒(méi)有安裝舍哄。

獲取app的url schemes

把相應(yīng)的app的ipa 安裝文件下載下來(lái)宴凉，把文件 .ipa的后綴改成.zip，然后解壓表悬，打開(kāi) Payload/xxx.app/Info.plist這個(gè)文件弥锄，找到 URL types下的URL Schemes 下的數(shù)組對(duì)應(yīng)的值就是這個(gè) app 的 URL Scheme 了 。

驗(yàn)證一個(gè) URL Scheme 是否正確

在真機(jī)設(shè)備（此設(shè)備要安裝了待驗(yàn)證的 app）里面打開(kāi) Safari蟆沫，然后在地址欄中鍵入該應(yīng)用的 URL Scheme籽暇，后加 ://，比如 Weico 的饭庞，在地址欄中鍵入 weico:// 戒悠，然后點(diǎn)擊確定，如果能正常調(diào)用出 Weico舟山，即代表這個(gè) URL Scheme 正確可用绸狐。

3、應(yīng)用A跳轉(zhuǎn)到應(yīng)用B

判斷某個(gè)特定的App是否被安裝一般都是用來(lái)進(jìn)行跳轉(zhuǎn)或打開(kāi)的累盗，如果安裝了寒矿，我們?cè)撊绾螌?shí)現(xiàn)跳轉(zhuǎn)呢？

步驟一：用Xcode創(chuàng)建兩個(gè)iOS應(yīng)用程序項(xiàng)目若债，項(xiàng)目名稱分別為App-A符相、App-B。
步驟二：選擇項(xiàng)目App-B -> TARGETS -> Info -> URL Types -> URL Schemes拆座，設(shè)置App-B的URL Schemes為AppB主巍。

AppB

步驟三：在應(yīng)用程序App-A中添加一個(gè)用來(lái)點(diǎn)擊跳轉(zhuǎn)的Button，并監(jiān)聽(tīng)點(diǎn)擊事件挪凑，添加跳轉(zhuǎn)代碼孕索。

- (void)jumpToAppB
{
    // 1.獲取應(yīng)用程序App-B的URL Scheme
    NSURL *appBUrl = [NSURL URLWithString:@"AppB://?AppA"];
    
    // 2.判斷手機(jī)中是否安裝了對(duì)應(yīng)程序
    // iOS10 以后，canOpenURL與openURL合并為一個(gè)躏碳，可以實(shí)現(xiàn)動(dòng)態(tài)跳轉(zhuǎn)不用配置
    if ([[UIApplication sharedApplication] canOpenURL:appBUrl])
    {
        NSLog(@"打開(kāi)應(yīng)用程序App-B");
    }
    else
    {
        NSLog(@"沒(méi)有安裝");
    }
}

步驟四：需要將跳轉(zhuǎn)的UrlScheme添加到白名單即可搞旭。添加方法：info.plist 增加LSApplicationQueriesSchemes （array類型），把要跳轉(zhuǎn)的app的UrlScheme加進(jìn)去菇绵。

UrlScheme

運(yùn)行效果如下：

從A跳轉(zhuǎn)到B

4肄渗、跳轉(zhuǎn)到特定界面

很多時(shí)候，我們做應(yīng)用程序之間的跳轉(zhuǎn)并不只是跳轉(zhuǎn)到其他程序就可以了咬最，而是要跳轉(zhuǎn)到其他程序的特定頁(yè)面上翎嫡。比如我們?cè)跒g覽網(wǎng)頁(yè)時(shí)，會(huì)有分享到微信朋友圈或是分享給微信朋友永乌，這就需要跳轉(zhuǎn)到微信朋友圈界面或是微信朋友選擇界面惑申。具體如何做呢？

步驟一：在APP-B中創(chuàng)建兩個(gè)界面WriterViewController和WasteMaterialsViewController翅雏。
步驟二：在應(yīng)用程序App-A中添加兩個(gè)用來(lái)點(diǎn)擊跳轉(zhuǎn)的Button圈驼，一個(gè)跳轉(zhuǎn)到WriterViewController，一個(gè)跳轉(zhuǎn)到WasteMaterialsViewController望几，并監(jiān)聽(tīng)點(diǎn)擊事件绩脆，添加跳轉(zhuǎn)代碼。

- (void)jumpToAppBWriterViewController
{
    // 1.獲取應(yīng)用程序App-B的Page1頁(yè)面的URL
    NSURL *appBUrl = [NSURL URLWithString:@"AppB://WriterViewController"];

    // 2.判斷手機(jī)中是否安裝了對(duì)應(yīng)程序并跳轉(zhuǎn)
    if ([[UIApplication sharedApplication] canOpenURL:appBUrl])
    {
        [[UIApplication sharedApplication] openURL:appBUrl options:@{UIApplicationOpenURLOptionsSourceApplicationKey : @YES} completionHandler:^(BOOL success) {

            if (!success)
            {

                UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"不能完成跳轉(zhuǎn)" message:@"請(qǐng)確認(rèn)App已經(jīng)安裝" preferredStyle:UIAlertControllerStyleAlert];
                UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"確定"style:UIAlertActionStyleCancel handler:nil];
                [alertController addAction:cancelAction];
                [self  presentViewController:alertController animated:YES completion:nil];
            }
            else if(self.isBack)
            {
                [self dismissViewControllerAnimated:YES completion:nil];
            }
        }];
    }
    else
    {
        NSLog(@"沒(méi)有安裝");
    }
}

- (void)jumpToAppBWasteMaterialsViewController
{
    // 1.獲取應(yīng)用程序App-B的Page1頁(yè)面的URL
    NSURL *appBUrl = [NSURL URLWithString:@"AppB://WasteMaterialsViewController"];

    // 2.判斷手機(jī)中是否安裝了對(duì)應(yīng)程序并跳轉(zhuǎn)
    if ([[UIApplication sharedApplication] canOpenURL:appBUrl])
    {
        [[UIApplication sharedApplication] openURL:appBUrl options:@{UIApplicationOpenURLOptionsSourceApplicationKey : @YES} completionHandler:^(BOOL success) {

            if (!success)
            {

                UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"不能完成跳轉(zhuǎn)" message:@"請(qǐng)確認(rèn)App已經(jīng)安裝" preferredStyle:UIAlertControllerStyleAlert];
                UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"確定"style:UIAlertActionStyleCancel handler:nil];
                [alertController addAction:cancelAction];
                [self  presentViewController:alertController animated:YES completion:nil];
            }
            else if(self.isBack)
            {
                [self dismissViewControllerAnimated:YES completion:nil];
            }
        }];
    }
    else
    {
        NSLog(@"沒(méi)有安裝");
    }
}

步驟三：在應(yīng)用App-B中通過(guò)AppDelegate監(jiān)聽(tīng)跳轉(zhuǎn)橄抹，進(jìn)行判斷靴迫，執(zhí)行不同頁(yè)面的跳轉(zhuǎn)。

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url
            options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
    NSString *sourceId = options[@"UIApplicationOpenURLOptionsSourceApplicationKey"];
    NSLog(@"openURL:url=%@;sourceId=%@;options=%@",url,sourceId,options);
    
    // 1.獲取導(dǎo)航欄控制器
    UINavigationController *rootNavigationVC = (UINavigationController *)self.window.rootViewController;

    // 2.每次跳轉(zhuǎn)前必須是在根控制器(細(xì)節(jié))
    [rootNavigationVC popToRootViewControllerAnimated:NO];

    // 3.根據(jù)字符串關(guān)鍵字來(lái)跳轉(zhuǎn)到不同頁(yè)面
    if ([url.absoluteString containsString:@"WriterViewController"]) //跳轉(zhuǎn)到應(yīng)用App-B的WriterViewController頁(yè)面
    {
        // 進(jìn)行跳轉(zhuǎn)
        WriterViewController *vc = [[WriterViewController alloc] init];
        [rootNavigationVC pushViewController:vc animated:YES];
    }
    else if ([url.absoluteString containsString:@"WasteMaterialsViewController"])// 跳轉(zhuǎn)到應(yīng)用App-B的WasteMaterialsViewController頁(yè)面
    {
        // 進(jìn)行跳轉(zhuǎn)
        WasteMaterialsViewController *vc = [[WasteMaterialsViewController alloc] init];
        [rootNavigationVC pushViewController:vc animated:YES];
    }

    return YES;
}

運(yùn)行效果如下：

跳轉(zhuǎn)到特定界面

5楼誓、從應(yīng)用B跳轉(zhuǎn)回應(yīng)用A

a矢劲、實(shí)現(xiàn)方案

我們想要從應(yīng)用B再跳轉(zhuǎn)回應(yīng)用A，那么在跳轉(zhuǎn)到應(yīng)用B的時(shí)候慌随，還應(yīng)將應(yīng)用A的URL Schemes傳遞過(guò)來(lái)芬沉，這樣我們才能判斷應(yīng)該跳轉(zhuǎn)回哪個(gè)應(yīng)用程序。我們指定一個(gè)傳遞URL的規(guī)則：協(xié)議頭://應(yīng)用B的URL Schemes?應(yīng)用A的URL Schemes阁猜。即：AppB://WriterViewController?AppA丸逸。AppB是跳轉(zhuǎn)過(guò)來(lái)的應(yīng)用App-B的URL Schemes；WriterViewController是用來(lái)區(qū)別跳轉(zhuǎn)頁(yè)面的標(biāo)識(shí)剃袍；? 是分割符黄刚；AppA是跳轉(zhuǎn)回的應(yīng)用App-A的URL Schemes。

我們根據(jù)傳遞來(lái)的數(shù)據(jù)民效，進(jìn)行反跳回去憔维。之前我們?cè)趹?yīng)用App-B中通過(guò)AppDelegate執(zhí)行不同頁(yè)面的跳轉(zhuǎn)涛救。在對(duì)應(yīng)方法中我們可以拿到完整的URL，在主控制器ViewController中設(shè)定一個(gè)屬性业扒，將該URL保存在主控制器中检吆。在將要跳轉(zhuǎn)的頁(yè)面控制器中定義一個(gè)屬性，用于接受程储、截取出跳轉(zhuǎn)回的應(yīng)用（即App-A）的URL Schemes蹭沛，執(zhí)行跳轉(zhuǎn)。

b章鲤、具體步驟

步驟一：因?yàn)槲覀兿胍D(zhuǎn)回應(yīng)用A摊灭，首先我們要先設(shè)置應(yīng)用App-A的URL Schemes，將其設(shè)置為AppA败徊。同時(shí)在應(yīng)用App-B中添加白名單帚呼。
步驟二：在App-B項(xiàng)目中的兩個(gè)頁(yè)面各添加一個(gè)Button，用于跳轉(zhuǎn)回App-A皱蹦。
步驟三：在App-A中修改傳遞的URL萝挤，分別修改為：AppB://WriterViewController?AppA、AppB://WasteMaterialsViewController?AppA根欧。
步驟四：在將要跳轉(zhuǎn)的頁(yè)面控制器WasteMaterialsViewController和WriterViewController中定義一個(gè)屬性@property (nonatomic, copy) NSString *urlString;怜珍，用于接受、截取出跳轉(zhuǎn)回的應(yīng)用（即App-A）的URL Schemes凤粗，執(zhí)行跳轉(zhuǎn)酥泛。
步驟五：在App-B的AppDelegate中傳遞URL。

// 進(jìn)行跳轉(zhuǎn)
WriterViewController *vc = [[WriterViewController alloc] init];
// 保存完整的App-A的URL給主控制器
vc.urlString = url.absoluteString;
[rootNavigationVC pushViewController:vc animated:YES];

步驟六：實(shí)現(xiàn)跳轉(zhuǎn)回APP-A的方法嫌拣。

- (void)backToAppA
{
    // 1.拿到對(duì)應(yīng)應(yīng)用程序的URL Scheme
    NSString *urlSchemeString = [[self.urlString componentsSeparatedByString:@"?"] lastObject];
    NSString *urlString = [urlSchemeString stringByAppendingString:@"://"];
    
    // 2.獲取對(duì)應(yīng)應(yīng)用程序的URL
    NSURL *appAUrl = [NSURL URLWithString:urlString];
    
    // 3.判斷是否可以打開(kāi)
    if (appAUrl && [[UIApplication sharedApplication] canOpenURL:appAUrl])
    {
        [[UIApplication sharedApplication] openURL:appAUrl options:@{UIApplicationOpenURLOptionsSourceApplicationKey : @YES} completionHandler:^(BOOL success) {

            if (!success)
            {

                UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"不能完成跳轉(zhuǎn)" message:@"請(qǐng)確認(rèn)App已經(jīng)安裝" preferredStyle:UIAlertControllerStyleAlert];
                UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"確定"style:UIAlertActionStyleCancel handler:nil];
                [alertController addAction:cancelAction];
                [self  presentViewController:alertController animated:YES completion:nil];
            }
            else if(self.isBack)
            {
                [self dismissViewControllerAnimated:YES completion:nil];
            }
        }];
    }
    else
    {
        NSLog(@"沒(méi)有安裝");
    }
}

六、網(wǎng)絡(luò)信息

廣告位標(biāo)識(shí)符：在同一個(gè)設(shè)備上的所有App都會(huì)取到相同的值吓歇，是蘋(píng)果專門(mén)給各廣告提供商用來(lái)追蹤用戶而設(shè)的，用戶可以在設(shè)置|隱私|廣告追蹤里重置此id的值票腰，或限制此id的使用城看，故此id有可能會(huì)取不到值，但好在Apple默認(rèn)是允許追蹤的丧慈，而且一般用戶都不知道有這么個(gè)設(shè)置析命，所以基本上用來(lái)監(jiān)測(cè)推廣效果主卫，是戳戳有余了逃默。

UUID：是Universally Unique Identifier的縮寫(xiě)，中文意思是通用唯一識(shí)別碼簇搅。它是讓分布式系統(tǒng)中的所有元素完域，都能有唯一的辨識(shí)資訊，而不需要透過(guò)中央控制端來(lái)做辨識(shí)資訊的指定瘩将。這樣吟税，每個(gè)人都可以建立不與其它人沖突的 UUID。在此情況下姿现，就不需考慮數(shù)據(jù)庫(kù)建立時(shí)的名稱重復(fù)問(wèn)題肠仪。蘋(píng)果公司建議使用UUID為應(yīng)用生成唯一標(biāo)識(shí)字符串。

    "utun5/ipv6" = "fe80::a033:c7cf:1848:d69c";

}

顧名思義這就是不同網(wǎng)絡(luò)環(huán)境下的IPv4 浑彰、IPv6地址，其中我們需要用到下面這幾個(gè)拯辙。其他的當(dāng)然也有用郭变，比如打開(kāi)熱點(diǎn)之后的也能在里面找到。

#define IOS_CELLULAR    @"pdp_ip0" // 蜂窩網(wǎng)絡(luò)
#define IOS_WIFI        @"en0" // WiFi網(wǎng)絡(luò)
#define IOS_VPN         @"utun0" // VPN

#define IP_ADDR_IPv4    @"ipv4"
#define IP_ADDR_IPv6    @"ipv6"

d涯保、判斷是否支持IPv6

拿到地址之后判斷我們常用的這三個(gè)地址中有沒(méi)有IPv6的可用地址诉濒，因?yàn)橛貌煌O(shè)備多獲取幾次地址，你就會(huì)發(fā)現(xiàn)其中有不可用地址夕春，比如IPv4中 127.0.0.1未荒、169.254.120.241，IPv6中 以fe80開(kāi)頭的地址及志。所以 片排，如果地址中有可用的IPv6那就說(shuō)明當(dāng)前設(shè)備的網(wǎng)絡(luò)環(huán)境支持IPv6。接下來(lái)我們就按照這個(gè)規(guī)則來(lái)判斷是否支持IPv6速侈。

+(BOOL)isSupportIpv6
{
    NSArray *searchArray =
    @[ IOS_VPN @"/" IP_ADDR_IPv6,
       IOS_VPN @"/" IP_ADDR_IPv4,
       IOS_WIFI @"/" IP_ADDR_IPv6,
       IOS_WIFI @"/" IP_ADDR_IPv4,
       IOS_CELLULAR @"/" IP_ADDR_IPv6,
       IOS_CELLULAR @"/" IP_ADDR_IPv4 ] ;
    
    NSDictionary *addresses = [self getDeviceIPAddresses];
    NSLog(@"addresses: %@", addresses);
    
    __block BOOL isSupportIpv6 = NO;
    [searchArray enumerateObjectsUsingBlock:^(NSString *key, NSUInteger idx, BOOL *stop) {
        NSLog(@"key: %@---addresses[key]: %@",key, addresses[key] );
        
        if ([key rangeOfString:@"ipv6"].length > 0  && ![[NSString stringWithFormat:@"%@",addresses[key]] hasPrefix:@"(null)"] )
        {
            if (![addresses[key] hasPrefix:@"fe80"])
            {
                isSupportIpv6 = YES;
            }
        }
    }];
    return isSupportIpv6;
}

e率寡、獲取IP地址

已經(jīng)判斷好IPv6了，然后該取IP地址了倚搬。這個(gè)時(shí)候因?yàn)橛?code>IPv6存在的原因冶共，所以獲取地址也需要區(qū)分一下。

+ (NSString *)getNetworkIPAddress
{
    NSArray *searchArray = [self isSupportIpv6] ?
    @[ IOS_WIFI @"/" IP_ADDR_IPv6, IOS_WIFI @"/" IP_ADDR_IPv4, IOS_CELLULAR @"/" IP_ADDR_IPv6, IOS_CELLULAR @"/" IP_ADDR_IPv4 ] :
    @[ IOS_WIFI @"/" IP_ADDR_IPv4, IOS_WIFI @"/" IP_ADDR_IPv6, IOS_CELLULAR @"/" IP_ADDR_IPv4, IOS_CELLULAR @"/" IP_ADDR_IPv6 ] ;
    
    NSDictionary *addresses = [self getIPAddresses];
    
    __block NSString *address;
    [searchArray enumerateObjectsUsingBlock:^(NSString *key, NSUInteger idx, BOOL *stop)
     {
        address = addresses[key];
        if([self isValidatIP:address])
        {
            *stop = YES;
        }
    }];
    NSLog(@"IPAddress: %@", address);
    return address ? address : @"0.0.0.0";
}

看到這個(gè)地方潭枣，肯定有人有疑問(wèn)了比默，為啥這個(gè)取值的數(shù)組searchArray里面還是包含有IPv4和IPv6？可以看到IPv4和IPv6的順序是不一樣的盆犁， 我的理解是這個(gè)地方的設(shè)備訪問(wèn)肯定是有順序的命咐，比如我蜂窩網(wǎng)絡(luò)雖然支持IPv6，但是我現(xiàn)在連上了WiFi谐岁，這個(gè)WiFi是IPv4的醋奠，那設(shè)備肯定是優(yōu)先使用WiFi進(jìn)行網(wǎng)絡(luò)訪問(wèn)榛臼。

f、如何判斷一個(gè)字符串是不是 IP 地址呢

從IPv4的特點(diǎn)入手：由4段數(shù)字組成窜司，其中有三個(gè)'.'符號(hào)沛善，每個(gè)數(shù)字的范圍都在0~255之間，且每個(gè)數(shù)都是合法的數(shù)字(前面沒(méi)有零)塞祈。所以我們可以先把這個(gè)字符串用‘.'分隔開(kāi)金刁，再統(tǒng)計(jì)一下'.'的個(gè)數(shù)，最后判斷每個(gè)數(shù)字是否合法即可议薪。判斷IPv6的思路和IPv4類似尤蛮，拆分并且判斷分隔符的個(gè)數(shù)，依次檢查每個(gè)數(shù)的正確性斯议，區(qū)別是IPv6的地址不需要判斷前導(dǎo)零产捞，但是需要注意大小寫(xiě)都是合法的。

實(shí)現(xiàn)方案一：正則表達(dá)式

+ (BOOL)isText:(NSString *)text pattern:(NSString *)pattern
{
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",pattern];
    return [predicate evaluateWithObject:text];
}

/**
 * 判斷字符串是否為IP地址
 * param iPAddress IP地址字符串
 * return BOOL 是返回YES哼御，否返回NO
 */
+ (BOOL)isIPAddress:(NSString *)iPAddress
{
    NSString *pattern = @"^(\\d{1,2}|1\\d\\d|2[0-4]\\d|25[0-5]).(\\d{1,2}|1\\d\\d|2[0-4]\\d|25[0-5]).(\\d{1,2}|1\\d\\d|2[0-4]\\d|25[0-5]).(\\d{1,2}|1\\d\\d|2[0-4]\\d|25[0-5])$";
    return [self isText:iPAddress pattern:pattern];
}

實(shí)現(xiàn)方案二：數(shù)字范圍

+ (BOOL)isValidIP:(NSString *)ipStr
{
    if (nil == ipStr)
    {
        return NO;
    }
    
    NSArray *ipArray = [ipStr componentsSeparatedByString:@"."];
    if (ipArray.count == 4)
    {
        for (NSString *ipnumberStr in ipArray)
        {
            int ipnumber = [ipnumberStr intValue];
            if (!(ipnumber>=0 && ipnumber<=255))
            {
                return NO;
            }
        }
        return YES;
    }
    return NO;
}
