Question

伙计们，我想在添加到UIImageVIew之后点击我的uiButton，但它不起作用。这是我的代码：

UIButton *btnDetail = [[UIButton buttonWithType:UIButtonTypeDetailDisclosure]retain];

btnDetail.frame = CGRectMake(0,0,100,100);
[btnDetail addTarget:self action:@selector(buttonClicked) forControlEvents:UIControlEventAllTouchEvents];

[self.imageView addSubview:btnDetail];

当我将它添加到UIImageVIew时，按钮无法单击，但如果我不将其添加到UIImageView，它可以正常工作。请有人帮助我

Answer 1

注意：默认情况下，UserInteraction的{{1}}属性设置为否。这是我们大多数人犯错误的地方。因此，在向UIImageView添加任何控件时检查的主要方法是将其UIImageView属性设置为 YES 。

UserInteractionEnabled

所以修改你的代码如下：

[self.imageView setUserInteractionEnabled:YES];

HAppy Coding ...

Answer 2

UIImageView默认情况下userInteractionProperty设置为NO，因此它不会处理触摸，也不会将它们传播到其子视图。尝试将其设置为YES：

self.imageView.userInteractionEnabled = YES;

Answer 3

嘿，我使用过这段代码。它的工作正常

 UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(80.0, 210.0, 100.0, 20.0);
[button addTarget:self action:@selector(show) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:@"ShowView" forState:UIControlStateNormal];

[image2 addSubview:button];
[image2 bringSubviewToFront:button];
[image2 setUserInteractionEnabled:YES];

Answer 4

如果某人在UIImageView中与UIButton存在交互问题，请执行后续步骤。

1创建UIImageView的属性：

@property (nonatomic, strong) UIImageView *buttonImageView;

2比合成它：

@synthesize buttonImageView = _buttonImageView;

3创建实施方法：

- (UIImageView *) buttonImageView {

    _buttonImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 100)];
    [_buttonImageView setBackgroundColor:[UIColor whiteColor]];
    [_buttonImageView setUserInteractionEnabled:YES];

    UIButton *addButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [addButton setTitle:@"add button" forState:UIControlStateNormal];
    addButton.frame = CGRectMake(0, 0, 160, 50);
    [addButton setUserInteractionEnabled:YES];
    [addButton setEnabled:YES];
    [addButton setAlpha:1];
    [addButton addTarget:self action:@selector(addNewImage) forControlEvents:UIControlEventTouchUpInside];

    return _buttonImageView;
}

4例如，在viewDidLoad方法中，将子视图添加到视图中：

[self.view addSubview:self.buttonImageView];

将UIButton添加到UIImageView时无法单击UIButton
