在視圖背景中的UIButton

Question

我在UITextView後面插入UIButton時遇到了問題。我可以製作按鈕，它的工作很好，但不管我做什麼，它總是在textView前面畫出來。

- (void)textViewDidBeginEditing:(UITextView *)textView 
{ 
self.backgroundButton = [[UIButton alloc] initWithFrame:self.view.frame]; 
[self.backgroundButton addTarget:textView action:@selector(resignFirstResponder) forControlEvents:UIControlEventTouchDown]; 
[self.view insertSubview:self.backgroundButton aboveSubview:textView]; 
[self.view bringSubviewToFront:textView]; 
} 

Answer 1

試試這個：

- (void)textViewDidBeginEditing:(UITextView *)textView 
{ 
self.backgroundButton = [[[UIButton alloc] initWithFrame:self.view.frame] autorelease]; 
[self.backgroundButton addTarget:textView action:@selector(resignFirstResponder) forControlEvents:UIControlEventTouchDown]; 
[self.view insertSubview:self.backgroundButton belowSubview:textView]; 
}
