我有一个使用计时器的 iPhone 应用程序,它会在每个时间间隔创建一些 UILabel
控件并将它们添加到 UIScrollView
中.
I have an iPhone application that uses a timer and at every time interval it creates some UILabel
controls and adds them into a UIScrollView
.
我要做的是在每次将 UIScrollView
控件放入 UIScrollView
之前清除 UIScrollView
.
What I want to do is to clear the UIScrollView
every time interval before it puts the UILabel
controls into the UIScrollView
.
如何清除UIScrollView
的内容?
for (UIView *subview in scrollView.subviews) {
[subview removeFromSuperview];
}
