10 个解决方案

#1

It is not possible without your custom image.

没有您的自定义图像是不可能的。

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

但是您应该在创建导航控制器后立即更改色调颜色:

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

#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.

您可以隐藏导航栏,并使用imageview创建自定义导航栏,并在其上放置2个按钮。通过这样做,您可以根据您的要求更改按钮的图像/颜色以及图像视图。

for hiding navigation bar:

隐藏导航栏:

 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.

然后在XIB中:创建一个44高度的视图,在其上放置imageview并在其上放置2个按钮和1个标签。

Hopely this will solve your problem.

希望这能解决你的问题。

@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.

@Ankit您可以尝试从导航栏中获取子视图,然后设置所需的颜色。我使用这种方法在搜索栏上设置取消按钮的颜色。取消按钮的大小为48 * 30,您可以使用子视图数组来设置所需的颜色。我不确定,但这可能会起作用。下面是我用来设置搜索栏上取消按钮颜色的代码。

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:

如果您想影响所有视图中出现的按钮的颜色,例如您希望更改的按钮的颜色,则只需使用以下内容:

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]];

- (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.

从iOS 5及更高版本开始,您可以使用新的UIAppearance API实现所需的自定义。本教程基本上向您展示了如何。

#7

You have to define a UIButtonTypeCustom button for your BarButtonItem.

您必须为BarButtonItem定义UIButtonTypeCustom按钮。

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

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

I hope it will help you!

我希望它会对你有所帮助!

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];

#9

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

如果您不介意在整个应用程序中使用相同的样式,请使用@Bourne建议的外观:

    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:

如果你像我一样使用白色,你也可以改变导航栏的背景颜色:

        picker.navigationBar.barTintColor = .redColor()

#10

One liner using UIAppearance:

使用UIAppearance的一个班轮:

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