由于iOS 10禁止了VoIP类应用常驻后台的权限，导致Xcode 8 打包出来的VoIP类应用后台长连接失效；官方推荐的方法是PushKit + CallKit，今天先来介绍下PushKit的使用。
官方文档：PKPushRegistry
证书配置就不在这里说了，下面开始划重点，也是我最想知道的几点：
1.该证书可与普通推送证书同时存在，且均可使用，但使用时注意这两种生成的token值是不同的
2.PushKit推送可在程序被杀死情况下执行代码，由于自定义程度比较高，目前貌似没有第三方推送支持

下面看一下实现，在Build Phases中加入PushKit.framework，AppDelegate中添加头文件#import <PushKit/PushKit.h>，添加代理PKPushRegistryDelegate
注册通知
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
PKPushRegistry *pushRegistry = [[PKPushRegistry alloc] initWithQueue:dispatch_get_main_queue()];
pushRegistry.delegate = self;
pushRegistry.desiredPushTypes = [NSSet setWithObject:PKPushTypeVoIP];
UIUserNotificationSettings *userNotifySetting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:userNotifySetting];
return YES;
}
PushKit代理
//获取token
- (void)pushRegistry:(PKPushRegistry *)registry didUpdatePushCredentials:(PKPushCredentials *)credentials forType:(NSString *)type{
NSString *str = [NSString stringWithFormat:@"%@",credentials.token];
NSLog(@"tokenStr = %@",str);
}
//收到推送后所走的方法，注意PushKit不会自己弹出推送框，如果需要自己写本地推送即可
- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(NSString *)type {
//在这里就可以做一些操作，比如使用CallKit唤起系统通话界面
UILocalNotification *backgroudMsg = [[UILocalNotification alloc] init];
if (backgroudMsg) {
backgroudMsg.timeZone = [NSTimeZone defaultTimeZone];
backgroudMsg.alertBody = @"VoIP来电";
backgroudMsg.alertAction = @"查看";
NSDictionary *infoDic = [NSDictionary dictionaryWithObject:@"name" forKey:@"key"];;
backgroudMsg.userInfo = infoDic;
[[UIApplication sharedApplication] presentLocalNotificationNow:backgroudMsg];
//[self cerateAVAudioPlayer];
}
}
原生推送代理
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings{
[application registerForRemoteNotifications];
}
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
NSString *token = [NSString stringWithFormat:@"%@", deviceToken];
}
找了好几个PHP文件都运行不起来，后来在网上发现了PushMeBaby
，先用这个进行测试吧，等有空再去找服务器代码。
下载好了之后，打开工程将voip_services.cer加入到工程里，修改token值跟证书路径，运行后会报错，将那一行直接改为#import <MacTypes.h>，再运行即可（没反应多运行几遍）。
- (id)init {
self = [super init];
if(self != nil) {
//注意token要带空格
self.deviceToken = @"26f7b0a8 efa8e6b3 6dde46c5 8d1a2cf8 e3583e31 87feab7d af6c8a54 24896f55";
self.payload = @"{\"aps\":{\"alert\":\"This is some fancy message.\",\"badge\":1}}";
self.certificate = [[NSBundle mainBundle] pathForResource:@"aps_development" ofType:@"cer"];
}
return self;
}
