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];
}
}
