如何拥有同时包含图像和文本的UIBarButtonItem?

问题描述

当我尝试将图像用于UIBarButtonItem时，未显示文本.有没有办法同时显示文字和图像?

When I try to use an image for a UIBarButtonItem, the text isn't shown. Is there a way to show both the text and the image?

推荐答案

您可以使用具有图像和文本的自定义视图来初始化UIBarButtonItem.这是一个使用UIButton的示例.

You can init the UIBarButtonItem with a custom view that has both image and text. Here's a sample that uses a UIButton.

UIImage *chatImage = [UIImage imageNamed:@"08-chat.png"];

UIButton *chatButton = [UIButton buttonWithType:UIButtonTypeCustom];
[chatButton setBackgroundImage:chatImage forState:UIControlStateNormal];
[chatButton setTitle:@"Chat" forState:UIControlStateNormal];
chatButton.frame = (CGRect) {
    .size.width = 100,
    .size.height = 30,
};

UIBarButtonItem *barButton= [[[UIBarButtonItem alloc] initWithCustomView:chatButton] autorelease];
self.toolbar.items = [NSArray arrayWithObject:barButton];
