Question

这是一个相当具体的问题，所以我不期待大量的回应，但值得一试。我正在使用SWRevealViewController作为我的应用程序，我想知道是否有人在使用SWRevealViewController时实现sliding status栏有任何好运。我有一些运气，但在推新观点时遇到了问题。

如果是这样，你介意分享你是如何做到这一点的吗？

Answer 1

我认为你可以使用RevealControllerdelegate方法来动画或更新它的x位置。像这样：

手动滑动更新状态栏：

- (void)revealController:(SWRevealViewController *)revealController panGestureMovedToLocation:(CGFloat)location progress:(CGFloat)progress overProgress:(CGFloat)overProgress {
    NSLog(@"6progress: %f", progress);

    UIView *statusBarView = [[UIApplication sharedApplication] valueForKey:[@[@"status", @"Bar"] componentsJoinedByString:@""]];

    statusBarView.transform = CGAffineTransformMakeTranslation(progress * self.revealViewController.rearViewRevealWidth, 0.0f);

}

切换操作时更新状态栏：

- (void) revealController:(SWRevealViewController *)revealController animateToPosition:(FrontViewPosition)position {

NSLog(@"animateToPosition: %ld", (long)position);

UIView *statusBarView = [[UIApplication sharedApplication] valueForKey:[@[@"status", @"Bar"] componentsJoinedByString:@""]];


if (!isDrawerOpen) {

    [UIView animateWithDuration:0.25 animations:^{
        statusBarView.transform = CGAffineTransformMakeTranslation(self.revealViewController.rearViewRevealWidth, 0.0f);
    } completion:^(BOOL finished) {
        isDrawerOpen = true;
    }];

} else {

    [UIView animateWithDuration:0.25 animations:^{
        statusBarView.transform = CGAffineTransformMakeTranslation(0, 0.0f);
    } completion:^(BOOL finished) {
        isDrawerOpen = false;
    }];

  }
}

Answer 2

上述解决方案尚未完成，并不适用于所有情况。这是完整而强大的解决方案。

<强> 1。定义本地布尔以在菜单打开时设置为true，在菜单关闭时设置为false。 @property (nonatomic, readwrite) BOOL isMenuOpen;。在我的例子中，我合成了它。

<强> 2。检测菜单何时打开以及何时关闭。

-(void)revealController:(SWRevealViewController *)revealController didMoveToPosition:(FrontViewPosition)position
{
    switch (position) {
        case FrontViewPositionLeftSideMostRemoved:
            NSLog(@"RevealView: FrontViewPositionLeftSideMostRemoved");
            break;

        case FrontViewPositionLeftSideMost:
            NSLog(@"RevealView: FrontViewPositionLeftSideMost");
            break;

        case FrontViewPositionLeftSide:
            NSLog(@"RevealView: FrontViewPositionLeftSide");
            break;

        case FrontViewPositionLeft:
            NSLog(@"RevealView: FrontViewPositionLeft");
            isMenuOpen = false;
            break;

        case FrontViewPositionRight:
            NSLog(@"RevealView: FrontViewPositionRight");
            isMenuOpen = true;
            break;

        case FrontViewPositionRightMost:
            NSLog(@"RevealView: FrontViewPositionRightMost");
            break;

        case FrontViewPositionRightMostRemoved:
            NSLog(@"RevealView: FrontViewPositionRightMostRemoved");
            break;

        default:
            break;
    }
}

第3。动画状态栏与上述答案类似，但更强大，例如菜单没有完全关闭并快速打开。

#pragma mark - SWRevealViewControllerDelegate

- (void)revealController:(SWRevealViewController *)revealController panGestureMovedToLocation:(CGFloat)location progress:(CGFloat)progress overProgress:(CGFloat)overProgress {
    UIView *statusBarView = [[UIApplication sharedApplication] valueForKey:[@[@"status", @"Bar"] componentsJoinedByString:@""]];

    statusBarView.transform = CGAffineTransformMakeTranslation(progress * self.revealViewController.rearViewRevealWidth, 0.0f);
}

- (void) revealController:(SWRevealViewController *)revealController animateToPosition:(FrontViewPosition)position {

    NSLog(@"animateToPosition: %ld", (long)position);

    UIView *statusBarView = [[UIApplication sharedApplication] valueForKey:[@[@"status", @"Bar"] componentsJoinedByString:@""]];


    if (position == FrontViewPositionRight) {
        [UIView animateWithDuration:0.25 animations:^{
            statusBarView.transform = CGAffineTransformMakeTranslation(self.revealViewController.rearViewRevealWidth, 0.0f);
        } completion:^(BOOL finished) {
            isMenuOpen = true;
        }];
    } else if (FrontViewPositionLeft) {
        [UIView animateWithDuration:0.25 animations:^{
            statusBarView.transform = CGAffineTransformMakeTranslation(0, 0.0f);
        } completion:^(BOOL finished) {
            isMenuOpen = false;
        }];
    }
}

<强> 4。使用通知检测设备轮换。当需要重新初始化状态栏时需要这样做。从风景回到肖像。把它放在viewDidLoad

中

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(deviceOrientationDidChange:)
                                             name:UIDeviceOrientationDidChangeNotification
                                           object:nil];

<强> 5。处理设备方向更改回到纵向（完成倒置）。

- (void)deviceOrientationDidChange:(NSNotification *)notification
{
    [self updateOrientationForStatusBar];
}

- (void)updateOrientationForStatusBar
{
    switch ([UIDevice currentDevice].orientation)
    {
        case UIDeviceOrientationPortrait:
        {
            UIView *statusBarView = [[UIApplication sharedApplication] valueForKey:[@[@"status", @"Bar"] componentsJoinedByString:@""]];

            if (isMenuOpen) {
                statusBarView.transform = CGAffineTransformMakeTranslation(self.revealViewController.rearViewRevealWidth, 0.0f);
            } else {
                statusBarView.transform = CGAffineTransformMakeTranslation(0, 0.0f);
            }

        }
            break;

        case UIDeviceOrientationLandscapeLeft:
        case UIDeviceOrientationLandscapeRight:
        case UIDeviceOrientationPortraitUpsideDown:
        case UIDeviceOrientationUnknown:
        case UIDeviceOrientationFaceUp:
        case UIDeviceOrientationFaceDown:
            break;
    }
}
