【问题描述】：

这是一个相当具体的问题，所以我预计不会有大量回复，但值得一试。我正在为我的应用程序使用SWRevealViewController，我想知道是否有人在使用 SWRevealViewController 时实现了sliding status 栏。我有一些运气，但在推送新视图时遇到了问题。

如果是这样，您介意分享一下您是如何做到这一点的吗？

【问题讨论】：

你有想过这个吗？我正在尝试解决同样的问题

【参考方案1】：

上述解决方案并不完整，并不适用于所有情况。这里是完整而强大的解决方案。

1.定义本地布尔值，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。

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;
    

3.动画状态栏类似于上面的答案，但如果例如更健壮菜单没有完全关闭，而是重新打开。

#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;
        ];
    

4.使用通知检测设备旋转。这是需要的，因为状态栏在例如从风景回到肖像。把这个放在viewDidLoad

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

5.处理设备方向更改回到纵向（要完成倒置）。

- (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;
    

【参考方案2】：

我认为您可以使用 RevealControllerdelegate 方法来设置动画或更新它的 x 位置。像这样的：

手动滑动时更新状态栏：

- (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);

在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;
    ];
