ios - iOS - UIView subclass won't rotate with device

Question

I have a custom UIView that I use to display synchronization in my device, but it won't rotate with the device when the orientation changes. Everything else rotates just fine, is there something I am missing to ensure my subclassed uiview will rotate?

Answer 1

Programmatically:

 - (BOOL)shouldAutorotate{
        return YES;
    }

add this. Hope this helps..

Or go to your Target Settings and click the directions you want it to rotate, but this will affect all your viewcontrollers.

Answer 2

您可以按照以下任何一种方法，

1-创建一个类来继承 UIView 并覆盖 .m（实现文件）中的 shouldAutorotate。现在在您的 viewController 中包含这个自定义 UIView 类来创建对象。

2-为 UIView 类创建类别

注意：- 如果您的构建应用程序支持 iOS6，那么不要忘记包含适用于您要求的方法

 >>>>>- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation;
 >>>>- (BOOL)shouldAutorotate;
 >>>>- (NSUInteger)supportedInterfaceOrientations;
 >>>>- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation;

类别示例：-

       @interface UIView (Additions)

       @end

       @implementation UIView (Additions)

           - (BOOL)shouldAutorotate{
              return YES;
                    }

       @end
