如何使UIView的子視圖放置在UIView框架之外，是交互式的？

Question

我已將一個UIView添加到視圖控制器的視圖。你說：

CGRect paneRect = {10.0f, 10.0f, 300.0f, 50.0f}; 
UIView *pane = [[UIView alloc] initWithFrame:paneRect]; 
pane.backgroundColor = [UIColor greenColor]; 
pane.userInteractionEnabled = YES; 
pane.clipsToBounds = NO; 
[self.view addSubview:pane]; 

然後我添加一個UIButton到pane：

CGRect testRect = {10.0f, 25.0f, pane.frame.size.width - 20.0f, 50.0f}; 
UIButton *test = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
[test setTitle:@"test" forState:UIControlStateNormal]; 
[test setFrame:testRect]; 
[pane addSubview:test]; 

現在一半的「測試」按鈕是窗格內，另一半超出。上半部分是互動的，並且對接觸做出反應，但下半部分不是。

是否有可能使整個「測試」按鈕，互動性和可觸摸，而不是它的一半？

Answer 1

如果你真的想使這些觀點堅持彼此，那麼你可以做這樣的事情

CGRect mainViewRect = {10.0f, 10.0f, 300.0f, 75.0f}; 
UIView *mainView = [[UIView alloc] initWithFrame:mainViewRect]; 
mainView.backgroundColor = [UIColor clearColor]; 
mainView.userInteractionEnabled = YES; 
[self.view addSubview:mainView]; 

CGRect paneRect = {0.0f, 0.0f, 300.0f, 50.0f}; 
UIView *pane = [[UIView alloc] initWithFrame:paneRect]; 
pane.backgroundColor = [UIColor greenColor]; 
pane.userInteractionEnabled = YES; 
pane.clipsToBounds = NO; 
[mainView addSubview:pane]; 



CGRect testRect = {10.0f, 25.0f, pane.frame.size.width - 20.0f, 50.0f}; 
UIButton *test = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
[test setTitle:@"test" forState:UIControlStateNormal]; 
[test setFrame:testRect]; 
[mainView addSubview:test]; 

Answer 2

只是不喜歡這種方式

CGRect paneRect = {10.0f, 10.0f, 300.0f, 50.0f}; 
UIView *pane = [[UIView alloc] initWithFrame:paneRect]; 
pane.backgroundColor = [UIColor greenColor]; 
pane.userInteractionEnabled = NO; 
pane.clipsToBounds = NO; 
[self.view addSubview:pane]; 


CGRect testRect = {10.0f, 25.0f, pane.frame.size.width - 20.0f, 50.0f}; 
UIButton *test = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
[test setTitle:@"test" forState:UIControlStateNormal]; 
test.userInteractionEnabled = YES; 
[test setFrame:testRect]; 
[pane addSubview:test]; 

對於UIButton的行動只是增加

[test addTarget:self action:@selector(processButtonCLick) forControlEvents:UIControlEventTouchUpInside]; 

如果你想UIButton的窗格的中心添加

test.center =pane.center;
