iOS如何实现强制转屏、强制横屏和强制竖屏的实例代码
本文介绍了iOS如何实现强制转屏、强制横屏和强制竖屏的实例代码,分享给大家
今天项目中遇到正在看视频的时候账号被挤,如果当时是横屏的情况下,需要强制竖屏。真头疼,网上找了好多方法,终于解决啦。O(∩_∩)O~
强制横屏:
[selfinterfaceOrientation:UIInterfaceOrientationLandscapeRight];
强制竖屏:
[selfinterfaceOrientation:UIInterfaceOrientationPortrait];
强制转屏
-(void)interfaceOrientation:(UIInterfaceOrientation)orientation { if([[UIDevicecurrentDevice]respondsToSelector:@selector(setOrientation:)]){ SELselector=NSSelectorFromString(@"setOrientation:"); NSInvocation*invocation=[NSInvocationinvocationWithMethodSignature:[UIDeviceinstanceMethodSignatureForSelector:selector]]; [invocationsetSelector:selector]; [invocationsetTarget:[UIDevicecurrentDevice]]; intval=orientation; //从2开始是因为01两个参数已经被selector和target占用 [invocationsetArgument:&valatIndex:2]; [invocationinvoke]; } }
