无法在iOS 6中处理方向？

Question

我正在使用

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

委托根据方向类型

更改视图的框架

即，

if(UIInterfaceOrientationIsLandscape(interfaceOrientation))
{
    self.view.frame=CGRectMake(0,0,500,300);
}
else
{
    self.view.frame=CGRectMake(0,0,300,400);
}

如何在iOS 6中处理与

相同的情况

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

已在iOS6中弃用。

我正在使用以下委托来设置所有方向。

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationAllMask;
}

但是，

-(BOOL)shouldAutoRotate
{
    return YES;

}

未被调用。如何处理这种情况？

Answer 1

在AppDelegate中，我已将ViewController对象添加到窗口

[self.window addSubView:viewControllerObj]

问题在于以上几行。方向将适用于iOS 5中的上述行，但在iOS中，为了使方向正常工作，请使用

更改上述行

[self.window setRootViewController:viewControllerObj]

然后当方向改变时，app会旋转。

Answer 2

确保项目和目标中的设置允许每种设备类型的方向。

此外，您shouldAutorotateToInterfaceOrientation:中的代码可以放入viewDidLayoutSubviews。

Answer 3

请记住，在iOS 6中，父母视图中的轮换处理非常谨慎。对childs viewcontrollers的责任较小。但是对于我们来说更烦人的是，在没有Interface builder的情况下编写代码。

Answer 4

确保启用所有方向。

Answer 5

在iOS 6中处理UINavigation方向问题

1创建UINavigation + Rotation类别类

2将下面的方法放在UINavigation + Rotation.m类

中

-(BOOL)shouldAutorotate
{
    return [[self.viewControllers lastObject] shouldAutorotate];
}

-(NSUInteger)supportedInterfaceOrientations
{
    return [[self.viewControllers lastObject]supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    if ([self.viewControllers count] == 0) {
        return UIInterfaceOrientationPortrait;
    }
    return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}

Answer 6

此方法适用于IOS 6及旧版本

-(BOOL)rotationChanged:(UIInterfaceOrientation)interfaceOrientation {
    NSInteger orientation = [[UIDevice currentDevice] orientation];
    UIWindow *_window = [[[UIApplication sharedApplication] delegate] window];
    if ([PGPlatformUtils GetCurrentPlatform]==PGPlatformEnum_iPhone) {
        switch (orientation) {
            case 1:
                [UIView beginAnimations:nil context:nil];
                [UIView setAnimationDuration:0.0];

                [_window setTransform:CGAffineTransformMakeRotation (0)];
                [_window setFrame:CGRectMake(0, 0, 320, 480)];
                [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:YES];

                [UIView commitAnimations];
                break;
            case 2:
                [UIView beginAnimations:nil context:nil];
                [UIView setAnimationDuration:0.0];

                [_window setTransform:CGAffineTransformMakeRotation (M_PI)];

                [UIView commitAnimations];
                break;

Answer 7

在iOS6中使用willAnimateRotationToInterfaceOrientation。
