Objective c - How to have a UIBarButtonItem with both image and text?

In Objective-C, UIBarButtonItem does not directly support having both an image and text simultaneously like UIButton does in iOS. However, you can achieve a similar effect by creating a custom UIView that contains both an UIImageView and a UILabel, and then setting this custom view as the customView property of the UIBarButtonItem. Here's how you can do it:

Step-by-Step Implementation

  1. Create a Custom View:

    • Create a custom UIView that will contain both the image and text.

  2. Add Image and Text:

    • Add an UIImageView for the image and a UILabel for the text within your custom view.

  3. Assign Custom View to UIBarButtonItem:

    • Set your custom view as the customView property of the UIBarButtonItem.

Example Code

Here's an example implementation:

CustomBarButtonItemView.h

#import <UIKit/UIKit.h> @interface CustomBarButtonItemView : UIView @property (nonatomic, strong) UIImageView *imageView; @property (nonatomic, strong) UILabel *label; - (instancetype)initWithImage:(UIImage *)image text:(NSString *)text; @end

CustomBarButtonItemView.m

#import "CustomBarButtonItemView.h" @implementation CustomBarButtonItemView - (instancetype)initWithImage:(UIImage *)image text:(NSString *)text { self = [super initWithFrame:CGRectMake(0, 0, 100, 44)]; // Adjust size as needed if (self) { self.imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 30, 30)]; // Adjust image size self.imageView.image = image; [self addSubview:self.imageView]; self.label = [[UILabel alloc] initWithFrame:CGRectMake(35, 0, 65, 44)]; // Adjust text position and size self.label.text = text; [self addSubview:self.label]; } return self; } @end

Usage in ViewController

- (void)viewDidLoad { [super viewDidLoad]; UIImage *image = [UIImage imageNamed:@"your_image"]; // Replace with your image name NSString *text = @"Your Text"; CustomBarButtonItemView *customView = [[CustomBarButtonItemView alloc] initWithImage:image text:text]; UIBarButtonItem *customBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:customView]; self.navigationItem.rightBarButtonItem = customBarButtonItem; }

Explanation:

  • CustomBarButtonItemView Class:

    • CustomBarButtonItemView is a subclass of UIView that initializes with an image and text. It positions an UIImageView for the image and a UILabel for the text within its frame.
    • Adjust the frame sizes and positions (initWithFrame: and initWithImage:text: methods) according to your design requirements.

  • Usage in ViewController:

    • In your view controller's viewDidLoad method (or wherever appropriate), create an instance of CustomBarButtonItemView with your desired image and text.
    • Create a UIBarButtonItem using initWithCustomView: and set it as the rightBarButtonItem of your navigationItem (or leftBarButtonItem as needed).

Considerations:

  • Customization: Modify the sizes, positions, fonts, and colors of the UIImageView and UILabel to fit your design.

  • Interaction: Unlike UIButton, UIBarButtonItem does not handle touch events directly. If you need interaction, you might need to handle tap gestures on the customView or consider using a UIButton instead.

By following these steps, you can create a UIBarButtonItem in Objective-C that displays both an image and text within a custom view. This approach allows you to achieve a button-like appearance with both image and text content.
