设置UIView的框架不起作用 [英] Setting the frame of an UIView does not work

问题描述

我在iOS 7中的frame-property有一个问题。
我想调整一些UIViews在 viewDidLoad - 我的 UIViewController ，但如果我这样做 int screenHeight = [[UIScreen mainScreen] bounds] .size.height;
[self.leftSideTableView setFrame：CGRectMake（0，0，320，screenHeight）];
高度设置为我想要的，直到方法结束，每一个其他方法，它是一直在之前！

它有什么问题，还是只是一个编译器或其他错误？

解决方案

必须将视图大小调整为<​​code> -viewDidLayoutSubviews：！ （文档） p>

将视图框架更改放置到 -viewWillAppear：或 -viewDidLoad：将无法工作，因为视图尚未布局！

I have a problem with the frame-property in iOS 7. I wanna resize some UIViews in the viewDidLoad-method of my UIViewController, but if I do it like int screenHeight = [[UIScreen mainScreen] bounds].size.height; [self.leftSideTableView setFrame: CGRectMake(0, 0, 320, screenHeight)]; the height is set as I want it till the end of the method, but in every other method it is as is has been before!

What's wrong with it or is it just a bug of the compiler or anything else?

解决方案

One has to put view resizing into -viewDidLayoutSubviews:! (documentation)

Placing view frame changes into -viewWillAppear: or -viewDidLoad: will not work, because the views are not laying out yet!
