How to make custom UIBarButtonItem with image and label?

iosobjective-cios7

提问by Dvole

I would like to make a custom UIBarButtonItem that contains both image and text, something like this:

我想制作一个包含图像和文本的自定义 UIBarButtonItem,如下所示:

enter image description here

在此处输入图片说明

I tried subclassing UIBarButtonItem and overriding this method:

我尝试子类化 UIBarButtonItem 并覆盖此方法:

- (UIView *)customView
{
    if (!self.storedView) {

        UIView *temp = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 120, 44)];
        UIImageView *tempImageView = [[UIImageView alloc] initWithImage:self.image];
        tempImageView.frame = CGRectMake(0, 0, self.image.size.width, self.image.size.height);
        UILabel *tempLabel = [[UILabel alloc] initWithFrame:CGRectMake(44, 0, 100, 44)];
        tempLabel.text = @"text";
        [temp addSubview:tempImageView];
        [temp addSubview:tempLabel];
        self.storedView = temp;
    }
    return self.storedView;
}

And I use it like this:

我像这样使用它:

UIBarButtonItem *left = [[LeftItem alloc] initWithTitle:@"Settings" style:UIBarButtonItemStylePlain target:self action:@selector(settingsPressed)];
left.title = @"Settings";
left.image = [UIImage imageNamed:@"settings.png"];
self.navigationItem.leftBarButtonItem = left;

But using this I only get the image, but not label. What am I doing wrong?

但是使用这个我只能得到图像,而不是标签。我究竟做错了什么?

UIButton *button =  [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:@"image.png"] forState:UIControlStateNormal];
[button addTarget:target action:@selector(buttonAction:)forControlEvents:UIControlEventTouchUpInside];
[button setFrame:CGRectMake(0, 0, 53, 31)];
UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(3, 5, 50, 20)];
[label setFont:[UIFont fontWithName:@"Arial-BoldMT" size:13]];
[label setText:title];
label.textAlignment = UITextAlignmentCenter;
[label setTextColor:[UIColor whiteColor]];
[label setBackgroundColor:[UIColor clearColor]];
[button addSubview:label];
UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationItem.leftBarButtonItem = barButton;

You can add a custom view to the UIBarButtonItem.

您可以将自定义视图添加到UIBarButtonItem.

In iOS 7, there is a new buttonType called UIButtonTypeSystemfor UIButtonwhich serve your purpose. Try this,

在 iOS 7 中,调用UIButtonTypeSystem了一个新的 buttonType来UIButton满足您的目的。尝试这个,

UIView* leftButtonView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 110, 50)];

UIButton* leftButton = [UIButton buttonWithType:UIButtonTypeSystem];
leftButton.backgroundColor = [UIColor clearColor];
leftButton.frame = leftButtonView.frame;
[leftButton setImage:[UIImage imageNamed:<YourImageName>] forState:UIControlStateNormal];
[leftButton setTitle:@"YourTitle" forState:UIControlStateNormal];
leftButton.tintColor = [UIColor redColor]; //Your desired color.
leftButton.autoresizesSubviews = YES;
leftButton.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin;
[leftButton addTarget:self action:@selector(<YourTargetMethod>) forControlEvents:UIControlEventTouchUpInside];
[leftButtonView addSubview:leftButton];

UIBarButtonItem* leftBarButton = [[UIBarButtonItem alloc]initWithCustomView:leftButtonView];
self.navigationItem.leftBarButtonItem = leftBarButton;

Updated Swiftcode,

更新了Swift代码,

let leftButtonView = UIView.init(frame: CGRect(x: 0, y: 0, width: 110, height: 50))

let leftButton = UIButton.init(type: .system)
leftButton.backgroundColor = .clear
leftButton.frame = leftButtonView.frame
leftButton.setImage(UIImage.init(imageLiteralResourceName: <YourImageName>), for: .normal)
leftButton.setTitle("YourTitle", for: .normal)
leftButton.tintColor = .red //Your desired color.
leftButton.autoresizesSubviews = true
leftButton.autoresizingMask = [.flexibleWidth , .flexibleHeight]
leftButton.addTarget(self, action: #selector(<YourTargetMethod>), for: .touchUpInside)
leftButtonView.addSubview(leftButton)

let leftBarButton = UIBarButtonItem.init(customView: leftButtonView)
navigationItem.leftBarButtonItem = leftBarButton

If your BarButtonItem is in Storyboard, you can drag another Button into BarButtonItem, so there will be a Button inside the BarButtonItem, you can add both image and label to the button.

如果您的 BarButtonItem 在 Storyboard 中,您可以将另一个 Button 拖到 BarButtonItem 中,这样 BarButtonItem 内部就会有一个 Button,您可以向该按钮添加图像和标签。

a SWIFT version

SWIFT 版本

    let button =  UIButton(type: .Custom)
    button.setImage(UIImage(named: "icon_right"), forState: .Normal)
        button.addTarget(self, action: "buttonAction", forControlEvents: .TouchUpInside)
    button.frame = CGRectMake(0, 0, 53, 31)
    button.imageEdgeInsets = UIEdgeInsetsMake(-1, 32, 1, -32)//move image to the right
    let label = UILabel(frame: CGRectMake(3, 5, 50, 20))
    label.font = UIFont(name: "Arial-BoldMT", size: 16)
    label.text = "title"
    label.textAlignment = .Center
    label.textColor = UIColor.whiteColor()
    label.backgroundColor =   UIColor.clearColor()
    button.addSubview(label)
    let barButton = UIBarButtonItem(customView: button)
    self.navigationItem.rightBarButtonItem = barButton

Using UIButton as custom view inside your UIBarButtonItem. You can create UIButton however you want, including with an image and text, using -setImage:forState:and -setTitle:forState:

在 UIBarButtonItem 中使用 UIButton 作为自定义视图。您可以根据需要创建 UIButton,包括图像和文本,使用-setImage:forState:-setTitle:forState:

UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:@"settings.png"] forState:UIControlStateNormal];
[button setTitle:@"Settings" forState:UIControlStateNormal];
[button addTarget:self action:@selector(buttonAction:)forControlEvents:UIControlEventTouchUpInside];
[button sizeToFit];
UIBarButtonItem* barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationItem.leftBarButtonItem = barButtonItem;

this can be done using interface builder just by dragging a UIButton to the left bar button slot on a navigation bar.

这可以使用界面构建器完成,只需将 UIButton 拖动到导航栏上的左侧栏按钮槽即可。

The problem with the accepted answer is that the UIBarButtonItemtext does not change when highlighted. The code below will display text plus an image. The UIEdgeInsetsMakemoves the text to the left and the image to the right.

已接受答案的问题在于UIBarButtonItem突出显示时文本不会更改。下面的代码将显示文本和图像。该UIEdgeInsetsMake移动文本左和右图。

UIButton *button =  [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self action:@selector(myButtonEvent:) 
             forControlEvents:UIControlEventTouchUpInside];
[button setFrame:CGRectMake(0, 0, 53, 32)];

[button setTitle:title forState:UIControlStateNormal];
[button setTitleColor:[UIColor whiteColor] 
                 forState:UIControlStateNormal];
[button setTitleColor:[UIColor lightGrayColor] 
                 forState:UIControlStateHighlighted];
button.titleEdgeInsets = UIEdgeInsetsMake(-2, -20, 2, 20);
button.titleLabel.font = font;
button.titleLabel.textAlignment = NSTextAlignmentLeft;

UIImage *image = [UIImage imageNamed:@"imageName"];
[button setImage:image 
        forState:UIControlStateNormal];
button.imageEdgeInsets = UIEdgeInsetsMake(-1, 32, 1, -32);
UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithCustomView:button];

Another approach with NSAttributedString:

NSAttributedString 的另一种方法:

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:@"Button Text"];
NSTextAttachment *textAttachment = [[NSTextAttachment alloc] init];
textAttachment.image = [UIImage imageNamed:@"buttonImage"];
textAttachment.bounds = CGRectMake(0, -3, textAttachment.image.size.width, textAttachment.image.size.height); //the origin y value depends on the size of the image to get a perfect fit
NSAttributedString *attrStringWithImage = [NSAttributedString attributedStringWithAttachment:textAttachment];
[attributedString replaceCharactersInRange:NSMakeRange(0, 0) withAttributedString:attrStringWithImage]; // Adding the image at the beginning
[customButton setAttributedTitle:attributedString forState:UIControlStateNormal];
[customButton sizeToFit];
[customButton addTarget:self action:@selector(back:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *back = [[UIBarButtonItem alloc] initWithCustomView:customButton];

UIImage *image = [UIImage imageNamed:@"icon.png"];
UIImage *backgroundSelected = [UIImage imageNamed:@"icon_selected.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self action:@selector(ButtonTapped:event:)forControlEvents:UIControlEventTouchUpInside]; //adding action
[button setBackgroundImage:image forState:UIControlStateNormal];
[button setBackgroundImage:backgroundSelected forState:UIControlStateSelected];
button.frame = CGRectMake(0 ,0,35,35);

then make that button as your custom barbutton

然后将该按钮作为您的自定义栏按钮

UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationItem.leftBarButtonItem = barButton;
