通知未被识别

Question

我想发布通知没有太多成功！我能做到这一点 确定为键盘没有问题，但现在我想一个自定义的 如下：

在我rootview我有这个

.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永远不会被调用？

你能尝试发布您的通知：

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

发件人采取VC实例（个体经营），而不是零。也许这是解决你的问题。
