How to change button color on UIImagePickerController navigation bar?

问题

I have managed to change the color of the navigation bar but the color of the buttons is still black. Is there any way to change the color of the buttons as well? See below image.

UPDATE: Sorry had to remove the image due to copy right issue.

回答1:

It is not possible without your custom image.

but you should change the tint color as soon as you create the navigation controller:

 UIImagePickerController *pickerImg = [[UIImagePickerController alloc] init];
pickerImg.navigationBar.barStyle = UIBarStyleBlackOpaque; // Or whatever style.
// or
pickerImg.navigationBar.tintColor = [UIColor whateverColor];

回答2:

you can hide the naviagtion bar,and create a custom navagtion bar by using imageview and place 2 buttons on it.By doing this you can change the image/color of buttons as well as image view also as per your requirement.

for hiding navigation bar:

 self.navigationController.navigationBarHidden=YES;

then in XIB : create a view of 44 height ,place imageview on it and place 2 button and 1 label on it.

Hopely this will solve your problem.

@Ankit You can try getting the subviews from the navigation bar and then set the desired color . I used this approach to set the color of cancel button on the search bar . The size of the cancel button is 48*30 and you can use the subviews array to set the desired color. I am not sure but this may do the job . Below is the code i used to set the color of cancel button on the search bar.

NSArray *arrySearchSubviews=[searchBarFrnds subviews];
for (UIButton *btn in arrySearchSubviews) 
{
   CGRect rect=btn.frame;
    NSLog(@"width %f",rect.size.width);
    NSLog(@"height %f",rect.size.height);
    if (rect.size.width==48 ) 
    {
        [btn setTintColor:[UIColor colorWithRed:0 green:0.403f blue:0.4f alpha:1.0f]];
    }
}

If you want to affect the color of the buttons that appear in all views such as the one you are hoping to change, then simply use the following:

UIBarButtonItem *searchBarButton = [UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil];
[searchBarButton setTintColor:[UIColor colorWithRed:138.0/255.0 green:183.0/255.0 blue:64.0/255.0 alpha:1.0]];

I hope it will help you!

Step 1:

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
[self presentViewController:picker animated:YES completion:NULL];

Step 2:

/* Status bar color */
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];
/* Left button */
navigationController.navigationBar.tintColor = [UIColor blackColor];
/* Right button color  */
navigationController.navigationBar.topItem.rightBarButtonItem.tintColor = [UIColor blackColor];

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
    if ([navigationController isKindOfClass:[UIImagePickerController class]]) {
        if ([[UIDevice currentDevice] systemVersion].floatValue >= 8.0) {
            [viewController.navigationController.navigationBar setBarTintColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"navbar1"]]];
        } else {
            [viewController.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"navbar2"] forBarMetrics:UIBarMetricsDefault];
        }
    viewController.navigationController.navigationBar.tintColor = [UIColor whiteColor];
    UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 40)];
    titleLabel.textColor = [UIColor whiteColor];
    titleLabel.textAlignment = NSTextAlignmentCenter;
    titleLabel.font = [UIFont boldSystemFontOfSize:18.0f];
    titleLabel.text = @"photos";
    [viewController.navigationItem setTitleView:titleLabel];
    viewController.edgesForExtendedLayout = UIRectEdgeNone;
    }
}

You can achieve your desired customizations using the new UIAppearance APIs as of iOS 5 and onwards. This tutorial essentially shows you how.

回答8:

You have to define a UIButtonTypeCustom button for your BarButtonItem.

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
UIBarButtonItem *yourBarButton = [[UIBarButtonItem alloc] initWithCustomView:button];

For more information, have a look at this post: UIBarButtonItem with color?

回答9:

If you don't mind to use the same style across the whole app, use appearance as @Bourne suggested:

    let font = UIFont(name:"Montserrat-Bold", size:16)!
    let attributes: LTDictStrObj = [
        NSForegroundColorAttributeName: UIColor.whiteColor(),
        NSFontAttributeName: font,
    ]
    UIBarButtonItem.appearance().setTitleTextAttributes(attributes, forState: UIControlState.Normal)

You can also change the background color of the navigation bar if you're using white color like me:

        picker.navigationBar.barTintColor = .redColor()

One liner using UIAppearance:

[[UINavigationBar appearanceWhenContainedInInstancesOfClasses:@[[UIImagePickerController class]]] setTintColor:[UIColor redColor]];
