iphone - 如何关闭 UIAlertView？

Question

如何关闭 UIAlertView ？此代码不起作用。

@property (nonatomic, retain) UIAlertView *activityAlertView;
- (void)viewDidLoad 
{
self.activityAlertView = [[UIAlertView alloc] initWithTitle:@"Receiving data" message:@"\n\n"
                                                         delegate:self
                                                cancelButtonTitle:@"Cancel"
                                                otherButtonTitles:nil, nil];  
[activityAlertView show];
}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
}

-(void) myfunc
{
[self alertView:activityAlertView clickedButtonAtIndex:1];
}

UIAlertView 类的 - (void)dismissWithClickedButtonIndex:(NSInteger)buttonIndexAnimated:(BOOL)animated 方法可以满足您的需求。例如:

[myAlertView dismissWithClickedButtonIndex:-1 animated:YES];
