限制某些视图的自转 [英] restricting autorotation on certain views

问题描述

我的应用程序包含两个表视图控制器.在第一个中，我希望视图能够左右旋转(除了纵向模式)，但是在第二个表视图控制器中(我在点击第一个表中的单元格后导航到)我想要它只能在纵向模式下查看.我试过这段代码，但没有用，它一直在旋转.

my app contains two table view controllers. in the first one i want the view to be able to be rotated left and right (in addition to the portrait mode), however in the second table view controller ( which i navigate to after tapping a cell from the first table) i want it to only be viewed in portrait mode. i tried this code but it didn't work, it keeps on rotating.

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}

- (BOOL) shouldAutorotate {
    return NO;
}

注意:我确实从项目目标的摘要"选项卡中启用了左/右/纵向方向.有什么解决办法吗?

note: i did actually enabled the left/right/portrait orientation from the Summary tab of the project target. any fix?

推荐答案

为 UINavigationController 创建一个类别，其中包括以下方法:

Create a category for UINavigationController which include the following methods:

(适用于 iOS 6 和 iOS 5)

(Works both for iOS 6 and iOS 5)

- (BOOL)shouldAutorotate
    {
        return self.topViewController.shouldAutorotate;
    }

    - (NSUInteger)supportedInterfaceOrientations
    {
        return self.topViewController.supportedInterfaceOrientations;
    }

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
        return [self.topViewController shouldAutorotateToInterfaceOrientation:toInterfaceOrientation];
    }

然后在你的控制器中实现这些方法

Then implement these methods in your controllers

首先:

- (BOOL)shouldAutorotate {
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations {
    if (RUNNING_IPAD) {
        return UIInterfaceOrientationMaskAll;
    }
    else {
        return UIInterfaceOrientationMaskAllButUpsideDown;
    };
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    if (RUNNING_IPAD) {
        return YES;
    }
    else {
        return toInterfaceOrientation != UIInterfaceOrientationMaskPortraitUpsideDown;
    }
}

其次:

- (BOOL)shouldAutorotate {
    return NO;
}

- (NSUInteger)supportedInterfaceOrientations {
       return UIInterfaceOrientationMaskPortrait;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
        return NO;
}

项目的旋转设置应如下所示:

The rotation settings of the project should look like:
