iOS：我的故事板为横向，项目设置为横向，但在模拟器中仍然错误

Question

I want to make a landscape iPad app. I did below 3 things. the simulator orientation is landscape which is correct. However, the content is 90 degrees wrong, but they are right in the storyboard view, landscape. Is there anything I need to check?

1. I set my storyboard as landscape.

2. May project I already set "supported interface orientations" = landscape

3. Also used this code in view controller:

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { if (interfaceOrientation==UIInterfaceOrientationLandscapeLeft || interfaceOrientation==UIInterfaceOrientationLandscapeRight) return YES; else return NO; } 

Answer 1

Supported Interface Orientations is one thing. It didn't work for me until I did the following:

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

Answer 2

You have to use the following code on ALL of your viewcontrollers

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
        return (interfaceOrientation==UIInterfaceOrientationLandscapeLeft || interfaceOrientation==UIInterfaceOrientationLandscapeRight)
}

Answer 3

确保在Info.plist中也设置了“初始界面方向”。
