Change color of UIDocumentInteractionController na

问题:

Is there a way to change the tint/background color of UIDocumentInteractionController navigationbar?

回答1:

A cleaner version of @DOOManics implementation:

- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller
{
    return [self navigationController];
}

回答2:

If you put the UIDocumentInteractionController onto a UINavigationController it will automatically take the color its navbar. This is probably your root view navcontroller.

You do this with the documentInteractionControllerViewControllerForPreview method:

- (UIViewController *) documentInteractionControllerViewControllerForPreview: (UIDocumentInteractionController *) controller
{
    // Use the rootViewController here so that the preview is pushed onto the navbar stack
    MyAppDelegate *appDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];
    return appDelegate.window.rootViewController;
}

回答3:

[[UINavigationBar appearance] setTintColor:[UIColor colorWithRed:107.0/256.0 green:145.0/256.0 blue:35.0/256.0 alpha:1.0]];

Place this code in Appdelegate's didFinisLaunching method. It will change the color of the navigation bar for the whole app.

Try this code:

- (void)openEC:(NSURL*)url {  
     [UINavigationBar appearance].tintColor = [UIColor blueColor];  
     docController = [UIDocumentInteractionController interactionControllerWithURL:url];  
    [docController setDelegate:self];  
    [docController  presentOptionsMenuFromRect:self.view.bounds inView:self.view animated:YES];  
}

- (void)documentInteractionControllerDidDismissOptionsMenu:(UIDocumentInteractionController *)controller {  
    [UINavigationBar appearance].tintColor = [UIColor whiteColor];  
}

If you're not using a navigationController, you can set the navigation bar color in the UIDocumentInteractionController by setting the correct settings on the View of the UIViewController where you launch the UIDocumentInteractionController from.

Let's say you have UIViewController viewController1 (from somewhere here you launch the UIDocumentInteractionController), with a View1 in the storyboard.

With the Storyboard open, click on the View1 from the list of elements on the viewController1 and go to "Attributes inspectors" on the right side. The Background and the Tint set there will be used in your UIDocumentInteractionController as well afterwards.

Then you can just use:

- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller
{
    return self;
}

Note that inside the viewController1, you might have a Navigation Bar with different properties, and these will not be used in the UIDocumentInteractionController.

Swift version to @dvdfrddsgn implementation

Try this : (You need to implement UIDocumentInteractionControllerDelegate)

func documentInteractionControllerViewControllerForPreview(_ controller: UIDocumentInteractionController) -> UIViewController {
    return self.navigationController ?? self
}
