1.界面旋转,MainScreen的宽高不变,键盘位置不变
CGFloat duration = [UIApplication sharedApplication].statusBarOrientationAnimationDuration; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:duration]; self.view.transform =CGAffineTransformMakeRotation(M_PI/2); [UIView commitAnimations];
2.界面旋转,MainScreen的宽高改变,键盘位置不变
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 = UIInterfaceOrientationLandscapeRight; [invocation setArgument:&val atIndex:]; [invocation invoke];
}
3.界面旋转,MainScreen的宽高改变,键盘位置改变
a.General—>中勾选Lnadscape Left/Lnadscape Right,默认是勾选上了的
b.控制器中实现以下两个方法:
// 支持设备自动旋转
- (BOOL)shouldAutorotate
{
return YES;
} /**
* 设置特殊的界面支持的方向,这里特殊界面只支持Home在右侧的情况
*/
- (UIInterfaceOrientationMask)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeRight;
}
PS:如何判断当前是否横屏,一下3个方法都可以
self.interfaceOrientation(iOS 2.0~8.0)
[UIApplication sharedApplication] statusBarOrientation]
[[UIDevice currentDevice] orientation]
