[問題] pushnotification 的問題
如果我initial view controller 為Ａ
Ａ會push出B or Ｃ
Ｂ也會push出Ｄ
Ｃ也會push出Ｅ
當我接收到RemoteNotification時
不論當下任何的view controller
我都要push出一個特定的頁面
目前我的做法是
在AppDelegate中
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo {
[PFPush handlePush:userInfo];
NSLog(@"%@",userInfo);
[[NSNotificationCenter defaultCenter] postNotificationName:@"test"
object:nil userInfo:nil];
}
然後每個viewcontroller加上
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(handleCurrentViewController:) name:@"test" object:nil];
}
- (void)handleCurrentViewController:(NSNotification *)notification {
PushNotificationViewController* pvc = [self.storyboard
instantiateViewControllerWithIdentifier:@"PushNotification"];
[self presentViewController:pvc animated:YES completion:nil];
}
但是如果我現在在Ｂ頁面
因為Ｂ是由Ａpush出來的
所以我Ａ跟Ｂ都會接收到NSNotificationCenter的訊息
都會觸發
請問如何修改會比較好
