message:@"請點選四周的模態區域我就消失"
delegate:nil
cancelButtonTitle:@"確定"
otherButtonTitles:nil];
[alert show];

action:@selector(handleTapBehind:)];
[recognizerTap setNumberOfTapsRequired:1];
recognizerTap.cancelsTouchesInView = NO;
[alert.window addGestureRecognizer:recognizerTap];
}
- (void)handleTapBehind:(UITapGestureRecognizer *)sender{
if (sender.state == UIGestureRecognizerStateEnded){
CGPoint location = [sender locationInView:nil];
if (![alert pointInside:[alert convertPoint:location fromView:alert.window] withEvent:nil]){
[alert.window removeGestureRecognizer:sender];
[alert dismissWithClickedButtonIndex:0
animated:YES];
}
}
}
彈出一個UIAlertView,然後點選視窗之外的區域來關閉UIALertView,上述程式碼在ios6.x及之前版本都有效,但是ios7之後這樣的處理就達不到這樣的效果了。。。
有木有人處理個這樣的問題?ios7該如何處理?折騰了半天都實現了不。
實在不行最後就得來個自己實現UIAlertView類似的功能了。。。。。。
