6.0以前用下面的这种方式
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return (toInterfaceOrientation != UIInterfaceOrientationMaskPortraitUpsideDown);
}
{
return (toInterfaceOrientation != UIInterfaceOrientationMaskPortraitUpsideDown);
}
6.0以后要追加一下方式
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAllButUpsideDown;
}
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAllButUpsideDown;
}
UIInterfaceOrientationMaskLandscape 支持左右横屏
UIInterfaceOrientationMaskAll 支持四个方向旋转
UIInterfaceOrientationMaskAllButUpsideDown 支持除了UpsideDown以外的旋转
UIInterfaceOrientationPortrait 竖屏正常显示
