shouldAutorotateToInterfaceOrientation但沒有任何反應

Question

我們的應用程序被拒絕，因為應用程序不會顛倒旋轉。

所以我們有一個tabbar App，將此代碼添加到所有標簽...

shouldAutorotateToInterfaceOrientation

沒有意義，將此代碼添加到Appdelegate沒有幫助，我們做錯了什么？

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return YES;
}

Answer 1

UITabbarcontroller是UIViewcontroller的子類。 要解決您的問題，只需為您創建子類或為您添加類別UITabbarcontroller實現：

@interface UITabBarController (rotation)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation;
@end

@implementation UITabBarController (rotation)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
     return YES;
}
@end

如果您想使標簽欄僅旋轉為縱向和顛倒，請使用以下代碼

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationPortrait ||
            interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}

Answer 2

確保每個 UIViewController實現

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return YES;
}
