我正在向UIScrollView
添加子视图。对于这个问题,我简化了添加的视图:testView
它包含UIButton
我的滚动视图效果很好,但按钮上的触摸效果不佳。
这是我的代码:
__block CGFloat scrollViewContentSize = 0;
__block CGFloat buttonRectOrigineY = 0;
[self.itemsToDisplay enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
CGRect frameTest = CGRectMake(0, buttonRectOrigineY/2, 320, 200);
UIButton *testButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
testButton.frame = frameTest;
UIView *testView = [[UIView alloc] initWithFrame:frameTest];
[testView addSubview:testButton];
[self.articleScrollView addSubview:testView];
buttonRectOrigineY += 200;
scrollViewContentSize += 200;
}];
[self.articleScrollView setContentSize:CGSizeMake(320, scrollViewContentSize)];
这里是图像,以便很好地理解我的问题:

您可以使用bringSubviewToFront
来避免此问题
CGRect frameTest = CGRectMake(0, buttonRectOrigineY/2, 320, 200);
UIButton *testButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
testButton.frame = frameTest;
UIView *testView = [[UIView alloc] initWithFrame:frameTest];
[testView addSubview:testButton];
[testView bringSubviewToFront:testButton];
[self.articleScrollView addSubview:testView];
[self.articleScrollView bringSubviewToFront:testView];
如果您再次遇到问题,请在按钮周围应用边框并检查手动显示的按钮区域。

我误认为我的按钮和视图的框架。这是一个可以帮助任何人的工作代码。
__block CGFloat scrollViewContentSize = 0;
__block CGFloat buttonRectOrigineY = 0;
[self.itemsToDisplay enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
CGRect frameTestButton = CGRectMake(0, 0, 300, 150);
CGRect frameTestView = CGRectMake(10, buttonRectOrigineY, 300, 200);
UIButton *testButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
testButton.frame = frameTestButton;
testButton.backgroundColor = [UIColor greenColor];
UIView *testView = [[UIView alloc] initWithFrame:frameTestView];
if(idx == 0)
testView.backgroundColor = [UIColor yellowColor];
if(idx == 1)
testView.backgroundColor = [UIColor orangeColor];
if(idx == 2)
testView.backgroundColor = [UIColor redColor];
if(idx == 3)
testView.backgroundColor = [UIColor magentaColor];
if(idx == 4)
testView.backgroundColor = [UIColor purpleColor];
if(idx <= 4){
LogDebug(@"idx : %lu", (unsigned long)idx);
[testView addSubview:testButton];
[self.articleScrollView addSubview:testView];
[self.articleScrollView bringSubviewToFront:testView];
buttonRectOrigineY += 200;
scrollViewContentSize += 200;
}
}];
[self.articleScrollView setContentSize:CGSizeMake(320, scrollViewContentSize)];
