    return YES;

Answer 1

您不要在此方法中编写此代码。首先您必须在方法中返回 Yes -

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

然后你必须使用：

-(void)willRotateToInterfaceOrientation: (UIInterfaceOrientation)orientation
{ if(orientation == UIInterfaceOrientationPortrait)
// here your code
}
