PushKit是一種新的消息通知方式徘跪，旨在幫助voip應(yīng)用（iOS 8）和watch OSComplication（iOS 9）減少電池的使用榄攀，提供更好的用戶體驗(yàn)，app可以通過PushKit進(jìn)行喚醒，進(jìn)行一些操作脆贵，而不被用戶感知噪矛。
PushKit和APNS的區(qū)別
- APNS 遠(yuǎn)程推送 量蕊，在每次啟動(dòng)時(shí)只能獲取到一條推送內(nèi)容，并且相應(yīng)的處理必須在用戶進(jìn)行一定的操作后才能執(zhí)行艇挨。而PushKit可以在無操作的情況就能進(jìn)行消息的處理残炮。
- APNS需要獲取用戶的權(quán)限，如果用戶不同意接收推送缩滨，那么app就獲取不到deviceToken势就，相應(yīng)我們也就沒辦法推送給客戶端消息，而PushKit則可以脉漏，當(dāng)然如果用戶拒絕接收通知欄等推送苞冯，你想在PushKit的代理方法中，進(jìn)行本地推送侧巨，也是不可以的舅锄。
- PushKit類似于APNS的靜默推送，但是在送達(dá)率上比靜默推送可靠的多刃泡，用戶是可以沒有任何感知的巧娱。
PushKit的使用
申請(qǐng)證書
和申請(qǐng)其他證書一樣，但是voip證書并不區(qū)分生產(chǎn)和測試烘贴，只有一個(gè)
下載證書 voip_services.cer
app配置
打開Push Notifications開關(guān) 和 Background Modes里的Voice over IP開關(guān)
代碼設(shè)置
在AppDelegate中禁添，導(dǎo)入#import <PushKit/PushKit.h>
?? 這是一個(gè)iOS 8 以上的庫
在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 中進(jìn)行初始化設(shè)置。
PKPushRegistry * voipRegistry = [[PKPushRegistry alloc]initWithQueue:dispatch_get_main_queue()];
voipRegistry.delegate = self;
voipRegistry.desiredPushTypes = [NSSet setWithObject:PKPushTypeVoIP];
接收Token的方法桨踪，這個(gè)Token是區(qū)別于APNS的Token的老翘，兩個(gè)不是一回事。并且這個(gè)Token無論App卸載重裝，都是唯一的
- (void)pushRegistry:(PKPushRegistry *)registry didUpdatePushCredentials:(PKPushCredentials *)credentials forType:(NSString *)type{
NSString *str = [NSString stringWithFormat:@"%@",credentials.token];
NSString * tokenStr = [[[str stringByReplacingOccurrencesOfString:@"<" withString:@""]
stringByReplacingOccurrencesOfString:@">" withString:@""] stringByReplacingOccurrencesOfString:@" " withString:@""];
NSLog(@"TOKEN = %@",tokenStr);
}
接收消息的方法铺峭，打印一下
- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type {
NSDictionary *dic = [payload.dictionaryPayload objectForKey:@"aps"];
NSLog(@"******************* push Kit %@***********************",dic);
}
測試
測試一下墓怀，這里用PHP進(jìn)行推送，要注意的是卫键，一些第三方平臺(tái)是不支持PushKit的傀履。
Java需要p12的證書，php需要pem莉炉，這里需要將證書和專用密鑰導(dǎo)出(.p12)钓账，轉(zhuǎn)換成.pem 然后再將兩個(gè).pem合并起來
openssl pkcs12 -clcerts -nokeys -out cert.pem -in cert.p12
openssl pkcs12 -nocerts -out key.pem -in key.p12
cat cert.pem key.pem > ck.pem
PHP代碼
<?php
$deviceToken = '*******************';
//ck.pem密碼
$pass = '123456';
//消息內(nèi)容
$message = 'A test message!';
//數(shù)字
$badge = 4;
$sound = 'default';
$body = array();
$body['aps'] = array('alert' => $message);
//把數(shù)組數(shù)據(jù)轉(zhuǎn)換為json數(shù)據(jù)
$payload = json_encode($body);
echo strlen($payload),"\r\n";
$ctx = stream_context_create([
'ssl' => [
'verify_peer' => false,
'verify_peer_name' => false
// 'cafile' => '/path/to/bundle/entrust_2048_ca.cer',
]
]);
// $pem = dirname(__FILE__) .'/'.'ck.pem';
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $pass);
$fp = stream_socket_client('tls://gateway.sandbox.push.apple.com:2195',$err,$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
if (!$fp) {
print "Failed to connect $err $errstr\n";
return;
}
else {
print "Connection OK\n<br/>";
}
// send message
$msg = chr(0) . pack("n",32) . pack('H*', str_replace(' ', '', $deviceToken)) . pack("n",strlen($payload)) . $payload;
print "Sending message :" . $payload . "\n";
fwrite($fp, $msg);
fclose($fp);
/*
35 Connection OK
Sending message :{"aps":{"alert":"A test message!"}} ?
*/
cd 到當(dāng)前目錄 執(zhí)行php -f php文件名.php
出現(xiàn)這個(gè)則表示成功了
再來看看Xcode
如果你的應(yīng)用想要使用PushKit，那么最好在提交AppStore時(shí)拍攝一個(gè)視頻來證明你的App是有用到Voip的(拍攝一下你們App通話時(shí)進(jìn)入后臺(tái)狀態(tài)欄的顯示一般就可以了)絮宁，否則被拒的可能性很大
我嘗試提交了一下梆暮，被拒原因如下：
