UIButton 在 iOS7 中点击时不显示高亮 [英] UIButton not showing highlight on tap in iOS7

问题描述

我查看了大量有关类似内容的帖子，但没有一个完全匹配或解决此问题.从 iOS 7 开始，每当我将 UIButton 添加到 UITableViewCell 或什至页脚视图时，它都可以正常"工作，这意味着它会收到目标操作，但不会显示当您点击 UIButton 时通常会发生的小亮点.它使 UI 看起来很时髦，但不显示按钮对触摸的反应.

I've looked at a ton of posts on similar things, but none of them quite match or fix this issue. Since iOS 7, whenever I add a UIButton to a UITableViewCell or even to the footerview it works "fine", meaning it receives the target action, but it doesn't show the little highlight that normally happens as you tap a UIButton. It makes the UI look funky not showing the button react to touch.

我很确定这算作 iOS7 中的一个错误，但有没有人找到解决方案或可以帮我找到一个 :)

I'm pretty sure this counts as a bug in iOS7, but has anyone found a solution or could help me find one :)

我忘了提到如果我长按按钮它会突出显示，但不会像添加到标准视图那样快速点击.

I forgot to mention that it will highlight if I long hold on the button, but not a quick tap like it does if just added to a standard view.

代码:

创建按钮:

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    button.titleLabel.font = [UIFont systemFontOfSize:14];
    button.titleLabel.textColor = [UIColor blueColor];
    [button setTitle:@"Testing" forState:UIControlStateNormal];
    [button addTarget:self action:@selector(buttonPressed:) forControlEvents: UIControlEventTouchDown];
    button.frame = CGRectMake(0, 0, self.view.frame.size.width/2, 40);

我测试过的东西:

//移除 UITableView 上的手势识别器，以防它们挡路.

//Removing gesture recognizers on UITableView in case they were getting in the way.

for (UIGestureRecognizer *recognizer in self.tableView.gestureRecognizers) {
   recognizer.enabled = NO;
}

//从单元格中移除手势

//Removing gestures from the Cell

for (UIGestureRecognizer *recognizer in self.contentView.gestureRecognizers) {
       recognizer.enabled = NO;
    }

//这显示了轻微的触感，但这不是想要的样子

//This shows the little light touch, but this isn't the desired look

button.showsTouchWhenHighlighted = YES;

推荐答案

在那个 tableview 中你只需添加这个属性.

In that tableview you just add this property.

tableview.delaysContentTouches = NO;

并在您启动您刚刚添加以下代码的单元格后添加 cellForRowAtIndexPath.单元格的结构在 iOS 6 和 iOS 7 中明显不同.
iOS 7 我们有一个控件 UITableViewCellScrollView 在 UITableViewCell 和 content View 之间.

And add in cellForRowAtIndexPath after you initiate the cell you just add below code. The structure of the cell is apparently different in iOS 6 and iOS 7.
iOS 7 we have one control UITableViewCellScrollView In between UITableViewCell and content View.

for (id obj in cell.subviews)
{
    if ([NSStringFromClass([obj class]) isEqualToString:@"UITableViewCellScrollView"])
    {
        UIScrollView *scroll = (UIScrollView *) obj;
        scroll.delaysContentTouches = NO;
        break;
    }
}
