UIScrollView在iOS 6&；中不以编程方式滚动；7两者

出于测试目的，我创建了一个项目，其中有两个scrollview。第一个scrollview有我手动插入的图像，第二个scrollview有按钮列表（作为菜单）

我有左右两个按钮以编程方式滚动UIScrollView

单击此按钮后，我通过设置内容大小移动scrollview

myCounter.text = [NSString stringWithFormat:@"%d", [myCounter.text intValue] - 1];

CGRect page = CGRectMake(320*([myCounter.text intValue] ), 230, 320, 150);

[myScrollView scrollRectToVisible:page animated:YES];

CGRect page2 = CGRectMake(320*([myCounter.text intValue] ), 20, 320, 200);

[firstScrollView scrollRectToVisible:page2 animated:YES];

我面临的问题是只有第一个滚动视图被滚动，而不是第二个

我真的很困惑为什么会这样

我也附加在dropbox相同的项目作为代码是多一点

如果（iHey mate），请在viewDidLoad方法中设置scrollview的contentSize

[myScrollView setContentSize:CGSizeMake(320*3,200)];

谢谢，祝你有一个幸福的一天
我已经下载了你的代码并修改了下面的代码，你的“page.origin.y超出了contentSize.height”

你是认真的吗？如果你看到我的问题，我已经有了…
