在tabview控制器中禁用自动旋转视图 [英] Disable autorotate for view in tabview controller

问题描述

您好我如何禁用tabview控制器中的视图的自动旋转？

Hi how i can disable the autorotation for a view in a tabview controller??

我已尝试在导航类中禁用，但这是不可能的。

i have testet to disable in a navigationclass, but thats not possible.

这是我在AppDelegate.m中的didFinishLaunching。

Thats my didFinishLaunching in the AppDelegate.m.

我希望每个人都有一个想法？

I hope everyone have an idea??

谢谢！

推荐答案

旋转UIViewController，除了一个或者更多子视图

使用此方法：

Rotating a UIViewController except one or more subviews

Use this method:

-(void)counterRotateView:(UIView *)view
    toInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
    duration:(NSTimeInterval)duration
{
    NSParameterAssert(view);

    CALayer* layer = view.layer;
    CABasicAnimation* animation;
    animation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];

    CGFloat tau = 0;
    switch (toInterfaceOrientation) {
        case UIInterfaceOrientationLandscapeLeft:
            tau = 0.5; break;
        case UIInterfaceOrientationLandscapeRight:
            tau = -0.5; break;
        case UIInterfaceOrientationPortraitUpsideDown:
            tau = 1; break;
        case UIInterfaceOrientationPortrait:
        default:
            break;
    }
    animation.toValue = [NSNumber numberWithFloat:tau * M_PI];

    animation.duration = duration;
    animation.cumulative = YES;
    animation.repeatCount = 1;
    animation.removedOnCompletion = NO;
    animation.fillMode = kCAFillModeForwards;

    [layer addAnimation:animation forKey:@"transform.rotation.z"];
}

并从此处调用：

-(void) willRotateToInterfaceOrientation:
    (UIInterfaceOrientation)toInterfaceOrientation
    duration:(NSTimeInterval)duration
{
    [self counterRotateView:someView
        toInterfaceOrientation:toInterfaceOrientation
        duration:duration];
}
