Xcode 4.5:无法在Interface Builder中设置root视图autoresizingMask

Question

我对Xcode 4.5中的错误看起来很困惑.我无法在Interface Builder中设置新创建的UIViewController的根视图的autoresizingMask属性.以下是重现问题的步骤:

• 创建一个新的Storyboard
• 取消选中"文件"检查器中的"使用Autolayout"
• 选择默认场景的根视图
• 转到尺寸检查器
• "自动调整大小"对话框中的弹簧为虚线,灰色且无法单击(struts正常工作).

如果我删除现有视图并从对象库中拖动新视图,则新视图启用了autosizingMask(并且无法禁用).

这在我正在进行的两个项目上发生过两次,但在新创建的项目中却不会发生.我错过了什么吗？什么可以触发这种行为？

这是测试故事板的XML.第一个ViewController,storyboardIdentifier="springsWorking"我编辑的是删除原始视图,第二个storyboardIdentifier="default"是默认视图.

Answer 1

在"属性检查器"(右侧面板;图标看起来像滑块)中,在"模拟指标"下打开"大小"弹出窗口并选择"自由形式".这将解锁这些控件.(否则,它将大小与全屏匹配,因为它认为这是你想要的.)
