iOS如何实现强制转屏、强制横屏和强制竖屏的实
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:
[self interfaceOrientation:UIInterfaceOrientationLandscapeRight];
强制竖屏:
[self interfaceOrientation:UIInterfaceOrientationPortrait];
强制转屏
- (void)interfaceOrientation:(UIInterfaceOrientation)orientation { if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)]) { SEL selector = NSSelectorFromString(@"setOrientation:"); NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]]; [invocation setSelector:selector]; [invocation setTarget:[UIDevice currentDevice]]; int val = orientation; // 从2开始是因为0 1 两个参数已经被selector和target占用 [invocation setArgument:&val atIndex:2]; [invocation invoke]; } }
