按下按钮时,我正在尝试呼叫和提醒.我用这个:

-(IBAction)Add { 
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle: @"add button pressed"
                                                    message:@"Add to record"
                                                   delegate:nil     
                                          cancelButtonTitle:@"Cancel" 
                                          otherButtonTitles:@"OK", nil   ];
    [alert show];
    [alert release];    
} 

好的,这里没问题,两个按钮出现,确定并取消.现在我想检测我按下哪个按钮:

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    // the user clicked one of the OK/Cancel buttons
    if (buttonIndex == 0)
    {
       //just to show its working, i call another alert view
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle: @"OK WORKIng well"
                                                        message:@"no error"                                                                                                            delegate:nil 
                                              cancelButtonTitle:@"IWORKS" 
                                              otherButtonTitles:@"NO PRB", nil];
        [alert show];
        [alert release];    


    }
    else
    {
        NSLog(@"cancel");       
    } …

我有一个像这样的plist:

 <dict>  
   <key>11231654</key>
  <array>
      <string>hello</string>
      <string>goodbye</string>
  </array>
  <key>78978976</key>
  <array>
        <string>ok</string>
    <string>cancel</string>
   </array>

我用这个加载了plist:

    NSString *path = [[NSBundle mainBundle] pathForResource:
                    @"data" ofType:@"plist"];
    // Build the array from the plist  
    NSMutableArray *array3 = [[NSMutableArray alloc] initWithContentsOfFile:path];  

我怎样才能访问我的plist的每个元素？我想在plist中搜索匹配的键,而不是搜索其子项.我怎样才能做到这一点？有什么建议吗？

请提前!
