本文介紹了iOS如何實現強制轉屏、強制橫屏和強制豎屏的實例代碼,分享給大家
今天項目中遇到正在看視頻的時候賬號被擠,如果當時是橫屏的情況下,需要強制豎屏。真頭疼,網上找了好多方法,終於解決啦。O(∩_∩)O~
強制橫屏:
[self interfaceOrientation:UIInterfaceOrientationLandscapeRight];
強制豎屏:
[self interfaceOrientation:UIInterfaceOrientationPortrait];
強制轉屏
- (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; // 從2開始是因為0 1 兩個參數已經被selector和target占用 [invocation setArgument:&val atIndex:2]; [invocation invoke]; } }
