作为子视图添加到 UIView 后按钮不可单击

发布于 2024-12-12 02:32:01 字数 861 浏览 0 评论 0原文

我创建了一个名为 UICustomButton 的类，它是 UIView 的子类。我将 UIButton 添加到 UIView 作为 subview ，如下面的代码所示：

-(id)initWithButtonType:(NSString *)type
{
    self = [super init];
    if (self) 
    {
        self.customButton = [self setupButtonWithTitle:type andFrame:frame];
        [self addSubview:self.customButton];
        self.customButton addTarget:self action:@selector(buttonPressed) forControlEvents:UIControlEventTouchUpInside];

    }
    return self;
}

我面临的问题是，虽然按钮出现了，但它们不可点击。我向 UIView 添加按钮的方式有问题吗？

在此处输入图像描述

编辑：要添加，我在单元格中使用此自定义按钮类实例：

UICustomButton *customButton = [[UICustomButton alloc]initWithFrame:someFrame];
[cell.contentView addSubView:customButton];

I have created a class called UICustomButton, which is a subclass of UIView. I added a UIButton to UIView as a subview as shown in my code below:

-(id)initWithButtonType:(NSString *)type
{
    self = [super init];
    if (self) 
    {
        self.customButton = [self setupButtonWithTitle:type andFrame:frame];
        [self addSubview:self.customButton];
        self.customButton addTarget:self action:@selector(buttonPressed) forControlEvents:UIControlEventTouchUpInside];

    }
    return self;
}

The problem I am facing is that although the button appears, they are not clickable. Is there something wrong with the way I am adding the buttons to the UIView?

enter image description here

EDIT: To add on, I am using this custom button class instance to a cell:

UICustomButton *customButton = [[UICustomButton alloc]initWithFrame:someFrame];
[cell.contentView addSubView:customButton];

检查 UICustomButton 对象的框架，以及 self.customButton 是否超出其 superView 范围。

确保子视图的框架位于其父视图的框架内。我遇到这个问题两次，两次子视图的框架都不正确。

您应该检查所有属性 userInteractionEnabled 是否已打开：

检查显示具有此视图的单元格的 UITableView 的属性
检查 UITableViewCell 的属性，其中您将此视图添加为子视图
检查 UICustomButton 的属性
检查 -(id)initWithButtonType:(NSString *)type 中 customButton 的属性

我的按钮不起作用，因为我彼此有两个视图。正如您所看到的，第一个视图的宽度和高度均为 0 像素。我已将此视图设置为与 view2 相同的大小，然后我的按钮可以单击。

    UIView *view1 = [[UIView alloc] initWithFrame:CGRectMake(325, 346, 0, 0)];
    view1.alpha = 0.90;

    UIView *view2 = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 450, 150)];
    [view2.layer setCornerRadius:10.0f];
    view2.backgroundColor = [UIColor whiteColor];

    UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [btn addTarget:self action:@selector(addClosedToCollection) forControlEvents:UIControlEventTouchUpInside];
    [btn setFrame:CGRectMake(30, 30, 300, 32)];
    [btn setTitle:@"i'm a button" forState:UIControlStateNormal];

    [view2 addSubview:btn];
    [view1 addSubview:view2];

我希望我已经帮助别人了:)

My button was not working because i had two views in each other. The first view, as you can see, has a width and heigth of 0 pixels. I've made this view the same size as view2 and then my button was clickable.

    UIView *view1 = [[UIView alloc] initWithFrame:CGRectMake(325, 346, 0, 0)];
    view1.alpha = 0.90;

    UIView *view2 = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 450, 150)];
    [view2.layer setCornerRadius:10.0f];
    view2.backgroundColor = [UIColor whiteColor];

    UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [btn addTarget:self action:@selector(addClosedToCollection) forControlEvents:UIControlEventTouchUpInside];
    [btn setFrame:CGRectMake(30, 30, 300, 32)];
    [btn setTitle:@"i'm a button" forState:UIControlStateNormal];

    [view2 addSubview:btn];
    [view1 addSubview:view2];

i hope i've helped somebody out :)
