layoutSubviews中判断横竖屏
在ContentView中重写layoutSubviews方法,然后根据stausbar的方向判断当前视图的横竖屏。具体代码: -(void)layoutSubviews{ [super layoutSubviews]; UIDeviceOrientation interfaceOrientation=[[UIApplication sharedApplication] statusBarOrientation]; if (interfaceOrientation == UIDeviceOrientationPortrait || interfaceOrientation == UIDeviceOrientationPortraitUpsideDown) { //翻转为竖屏时 }else if (interfaceOrientation==UIDeviceOrientationLandscapeLeft || interfaceOrientation == UIDeviceOrientationLandscapeRight) { //翻转为横屏时 } }
