通知未被識別

Question

我想發佈通知沒有太多成功！我能做到這一點 確定爲鍵盤沒有問題，但現在我想一個自定義的 如下：

在我rootview我有這個

.H

-(void) allowEdits:(NSNotification *)notification; 

.M

//this section is run in method to present the passcode entry form 


[[NSNotificationCenter defaultCenter] addObserver:self 
selector:@selector(allowEdits:) name: @"PasscodeOK" object:nil]; 

PasscodeEntryViewController *vc = [[PasscodeEntryViewController alloc] 
init]; 

[self presentModalViewController: vc animated:YES]; 

[vc release]; 


// and this is the response to the notification 

-(void) allowEdits:(NSNotification *)notification { 

    NSLog(@"notification fired"); 
} 


// in the vc instance I have this to notify passcode was ok 

[[NSNotificationCenter defaultCenter] 
postNotificationName:@"PasscodeOK" object:nil]; 

[self dismissView]; 

但allowEdits永遠不會被調用？

你能嘗試發佈您的通知：

[[NSNotificationCenter defaultCenter] postNotificationName:@"PasscodeOK" object:self]; 

發件人採取VC實例（個體經營），而不是零。也許這是解決你的問題。
