如何使UIView的SubView放置在UIView框架之外，是否具有交互性？

Question

我在视图控制器的视图中添加了UIView。说：

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];

然后我在pane添加了一个UIButton：

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];

现在，“测试”按钮的一半在窗格内，另一半在外面。上半部分是交互式的，可以响应触摸，但下半部分不是。

是否有可能使整个“测试”按钮具有交互性和可触摸性，而不是它的一半？

Answer 1

就像这样做

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];

对于UIButton的行动，只需添加

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

如果你想要uibutton窗格中心添加

 test.center =pane.center;

如果你真的想让这些视图相互贴合，那么你可以做一些像这样的事情

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];
