ios杀死进程之后消息推送怎么跳转指定页面

Answer 1

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
#if __IPHONE_OS_VERSION_MAX_ALLOWED > __IPHONE_7_1
if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0) {
[APService registerForRemoteNotificationTypes:(UIUserNotificationTypeBadge |UIUserNotificationTypeSound | UIUserNotificationTypeAlert) categories:nil];
} else {
[APService registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)
#else
categories:nil];
[APService registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)
#endif
categories:nil];
}
[APService setupWithOption:launchOptions];
if (launchOptions) {
NSDictionary * remoteNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
//这个判断是在程序没有运行的情况下收到通知，点击通知跳转页面
if (remoteNotification) {
NSLog(@"推送消息==== %@",remoteNotification);
[self goToMssageViewControllerWith:remoteNotification];
}
}
}
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings{
[application registerForRemoteNotifications];
}
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
[APService registerDeviceToken:deviceToken];
NSLog(@"%@", [NSString stringWithFormat:@"Device Token: %@", deviceToken]);
}

// 当 DeviceToken 获取失败时，系统会回调此方法
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{
NSLog(@"DeviceToken 获取失败，原因：%@",error);
}

下面的这个方法也很重要，这里主要处理推送过来的消息
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
NSLog(@"尼玛的推送消息呢===%@",userInfo);
// 取得 APNs 标准信息内容，如果没需要可以不取
NSDictionary *aps = [userInfo valueForKey:@"aps"];
NSString *content = [aps valueForKey:@"alert"]; //推送显示的内容
NSInteger badge = [[aps valueForKey:@"badge"] integerValue];
NSString *sound = [aps valueForKey:@"sound"]; //播放的声音
// 取得自定义字段内容，userInfo就是后台返回的JSON数据，是一个字典
[APService handleRemoteNotification:userInfo];
application.applicationIconBadgeNumber = 0;
[self goToMssageViewControllerWith:userInfo];
}
- (void)applicationWillEnterForeground:(UIApplication *)application {
[application setApplicationIconBadgeNumber:0]; //清除角标
[application cancelAllLocalNotifications];
}
- (void)goToMssageViewControllerWith:(NSDictionary*)msgDic{
//将字段存入本地，因为要在你要跳转的页面用它来判断,这里我只介绍跳转一个页面，
NSUserDefaults*pushJudge = [NSUserDefaults standardUserDefaults];
[pushJudge setObject:@"push"forKey:@"push"];
[pushJudge synchronize];
NSString * targetStr = [msgDic objectForKey:@"target"];
if ([targetStr isEqualToString:@"notice"]) {
MessageVC * VC = [[MessageVC alloc]init];
UINavigationController * Nav = [[UINavigationController alloc]initWithRootViewController:VC];//这里加导航栏是因为我跳转的页面带导航栏，如果跳转的页面不带导航，那这句话请省去。
[self.window.rootViewController presentViewController:Nav animated:YES completion:nil];

}
}

下面介绍要跳转的页面MessageVC里面要做什么处理，其实里面的代码也很简单。看代码,在viewWillAppear里面自行创建一个返回按钮，根据在AppDelegate里面用NSUserDefaults保存的字段做判断。
-(void)viewWillAppear:(BOOL)animated{
[self.navigationController setNavigationBarHidden:NO animated:YES];
[super viewWillAppear:YES];
NSUserDefaults*pushJudge = [NSUserDefaults standardUserDefaults];
if([[pushJudge objectForKey:@"push"]isEqualToString:@"push"]) {
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"02_03f@2x.png"] style:UIBarButtonItemStylePlain target:self action:@selector(rebackToRootViewAction)];
}else{
self.navigationItem.leftBarButtonItem=nil;
}
}
- (void)rebackToRootViewAction {
NSUserDefaults * pushJudge = [NSUserDefaults standardUserDefaults];
[pushJudge setObject:@""forKey:@"push"];
[pushJudge synchronize];//记得立即同步
[self dismissViewControllerAnimated:YES completion:nil];
}
