iOS 6中的UIScrollView [英] UIScrollView in iOS 6

问题描述

最近我已经下载了Xcode 4.5（iOS 6），但是当我尝试继续我的一个项目时，我注意到UIScrollView无法正常工作，让我更清楚地解释一下：

Recently i've downloaded Xcode 4.5(iOS 6),but when tried to continue one of my projects i noticed that the UIScrollView isn't working properly,let me explain more clearly:

我创建了UIScrollView并使用以下代码添加了初始化它：

I've created the UIScrollView and added the initialized it using the following code:

-(void)viewDidLoad{

    [mainScrollView setScrollEnabled:YES];
    mainScrollView.contentSize = CGSizeMake(480, 0);

    [super viewDidLoad];

}

在我打开我的XIB并链接<$ c $之后c> mainScrollView 到UIScrollView后，我将一些UIButton添加到scrollView。当我构建项目时， mainScrollView 滚动但按钮没有' t出现了，我的意思是，我只能看到屏幕上已有的按钮。我做错了什么？我如何设置UIScrollView？

After i opened my XIB and linked the mainScrollView to a UIScrollView,after i added some UIButton's to the scrollView.When i built the project the mainScrollView was scrolling but the buttons didn't showed up,i mean,i just could see the button that were already on the screen.What i'm doing wrong?How can i setup the UIScrollView?

推荐答案

对于 xcode 4.5 ，如果你使用 scrollView 你必须在文件检查器中取消选中使用AutoLayout 。

For xcode 4.5 ,If you are using scrollView you have to either uncheck "use AutoLayout" in file inspector.

或者如果你想使用 AutoLayout ，然后在 .m（实施）文件中添加此

or if you want to "use AutoLayout",then in .m(implementation) file add this

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    theScroller.contentSize=CGSizeMake(1024.0,1300.0);
}
