zz做開(kāi)發(fā)已經(jīng)有一段時(shí)間了, 最近換了新公司, 決定寫(xiě)一些東西記錄一下開(kāi)發(fā)中遇到的坑. 新的公司做的是企業(yè)通訊方面的, 首先遇到的坑就是獲取手機(jī)通訊錄的信息.
由于版本適配的問(wèn)題, 這次采用的是AddressBook這個(gè)框架, 這個(gè)框架在iOS9以后已經(jīng)被Contacts所代替. 以后用到這個(gè)在做記錄吧,
廢話(huà)不多說(shuō)了, 這次要做的就是把通訊錄的信息取出來(lái)然后自定義界面展示.第一步要做的就是引入框架頭文件
import <AddressBook/AddressBook.h>
由于訪(fǎng)問(wèn)的是通訊錄要獲得用戶(hù)授權(quán)所有我們要寫(xiě)一個(gè)方法獲取用戶(hù)的授權(quán) 直接貼上代碼吧
新建一個(gè)model類(lèi), 做聯(lián)系人的model
屬性如下, 因?yàn)槲抑恍枰@幾個(gè)所以就只寫(xiě)著幾個(gè)了
#import "BaseModel.h"
#import <AddressBook/AddressBook.h> @interface ContactBookModel : BaseModel<NSCoding> @property (nonatomic, strong) NSString *name, *telephone, *lastName, *characterName; @property (nonatomic, strong) NSData *imageData; @property (nonatomic, assign) BOOL isSelect;
@end
下面是獲取通訊錄, 我們可以寫(xiě)一個(gè)類(lèi)專(zhuān)門(mén)處理這個(gè), 因?yàn)樵谕ㄓ嶄浀拈_(kāi)發(fā)中 , 我們可以在不同的控制器里會(huì)用到這個(gè)

//漢子轉(zhuǎn)換拼音 把漢子轉(zhuǎn)為拼音進(jìn)行排序是我遇到的最大的坑, 因?yàn)檫@個(gè)造成了二三十秒 卡頓 (大概有四千的通訊錄), 最后求助了一個(gè)群里的大神給了一個(gè)c文件

寫(xiě)到這里大概通訊錄的大概就有了, 數(shù)組為全部的, 字典是排過(guò)序的, 接下來(lái)做的就是存入沙盒中, 因?yàn)槲覀儾豢赡苊看味歼^(guò)來(lái)獲取通訊錄, 我們歸檔模型, 存入cache
model的.h中遵守NSCoding 而在.m中實(shí)現(xiàn)
- (void)encodeWithCoder:(NSCoder *)aCoder { [aCoder encodeObject:self.name forKey:@"name"]; [aCoder encodeObject:self.telephone forKey:@"telephone"]; [aCoder encodeObject:self.lastName forKey:@"lastName"]; [aCoder encodeObject:self.characterName forKey:@"characterName"]; [aCoder encodeObject:self.imageData forKey:@"imageData"]; [aCoder encodeBool:self.isSelect forKey:@"isSelect"]; }
- (nullable instancetype)initWithCoder:(NSCoder *)aDecoder { if (self = [super init]) { self.name = [aDecoder decodeObjectForKey:@"name"]; self.telephone = [aDecoder decodeObjectForKey:@"telephone"]; self.lastName = [aDecoder decodeObjectForKey:@"lastName"]; self.characterName = [aDecoder decodeObjectForKey:@"characterName"]; self.imageData = [aDecoder decodeObjectForKey:@"imageData"]; self.isSelect = [aDecoder decodeBoolForKey:@"isSelect"]; } return self; }
//下面寫(xiě)到沙盒中
- (void)writeToSandBox { NSString *cache = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) firstObject]; NSString *conactPath = [cache stringByAppendingPathComponent:@"contactArray.text"]; BOOL exist = [[NSFileManager defaultManager] fileExistsAtPath:conactPath]; if (exist) { BOOL result = [[NSFileManager defaultManager] removeItemAtPath:conactPath error:nil]; if (result) { NSLog(@"移除成功"); } else { NSLog(@"移除失敗"); } }
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ //我這里把總的數(shù)組存進(jìn)去了, 因?yàn)槲乙玫闹皇侨康臄?shù)組就行, 如果有需要可以把字典也存進(jìn)去 NSData *data = [NSKeyedArchiver archivedDataWithRootObject:self.contactArray]; BOOL result = [data writeToFile:conactPath atomically:YES]; if (result) { NSLog(@"寫(xiě)入成功"); }else { NSLog(@"寫(xiě)入失敗"); } }); }
//然后我們可以在用的地方存沙盒中取出來(lái)
//還沒(méi)有完, 因?yàn)槲覀冇脩?hù)會(huì)修改通訊錄的, 不過(guò)不要怕有修改的回調(diào)函數(shù), 我們?cè)赼ppdelegate中寫(xiě)下如下
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //類(lèi)似于觀察者, 當(dāng)用戶(hù)修改了通訊錄, 我們進(jìn)入程序會(huì)有回調(diào) ABAddressBookRef addresBook = ABAddressBookCreateWithOptions(NULL, NULL); ABAddressBookRegisterExternalChangeCallback(addresBook, addressBookChanged, (__bridge void *)(self)); return YES; }

//簡(jiǎn)書(shū)寫(xiě)文章排版也是一個(gè)大問(wèn)題, 以后好好學(xué)下也要, 這樣的排版我自己都不愿意看..... 我看看有沒(méi)有上傳文件的地方, 上傳一份最終要的是c文件漢子轉(zhuǎn)拼音的那個(gè)
