场景:小demo,实现横竖屏切换
步骤:
1. AppDelegate.m:添加:
- (UIInterfaceOrientationMask)application:(UIApplication*)application supportedInterfaceOrientationsForWindow:(UIWindow*)window
{
return UIInterfaceOrientationMaskAll;
}
2. 在想要设置横竖屏的页面添加:
- (BOOL)shouldAutorotate{
return YES;
}
//支持竖屏方向,同理可设置支持横屏或其他
- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
