iphone - 支持的接口方向和 shouldAutorotateToInterfaceOrientation

Question

在我的项目设置中，我将支持的界面方向设置为两个横向。

我还应该在每个视图控制器中实现下面吗？

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}

Answer 1

iOS < 6.x

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation // Deprecated in iOS 6.x 
{
    return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}

iOS > 6.x

- (BOOL) shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}

希望这会有所帮助。

Answer 2

是更好的实现，如果你在 info.plist 中实现它会更好

对于 ios>6

- (BOOL) shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}
