【问题描述】：

我正在 iphone 中以编程方式开发带有按钮的视图中的图像。现在我想为下一个和上一个按钮添加按钮背景图像。我想以编程方式为这些按钮添加图像。

如何在 iphone 中添加按钮图像。

【参考方案1】：

// 像这样添加按钮

UIImage *redButtonImage = [UIImage imageNamed:@"ExitButton.png"];

        UIButton *redButton = [UIButton buttonWithType:UIButtonTypeCustom];
        redButton.frame = CGRectMake(280.0, 10.0, 29.0, 29.0);
        [redButton setBackgroundImage:redButtonImage forState:UIControlStateNormal];

        [view addSubview:redButton];

【参考方案2】：

你可以试试这个

 UIImage *buttonImage = [UIImage imageNamed:@"image.png"];

//create the button and assign the image
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:buttonImage forState:UIControlStateNormal];


//create a UIBarButtonItem with the button as a custom view
//UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];

[button addTarget:self action:@selector(clickActionItem:) forControlEvents:UIControlEventTouchUpInside];

祝你好运

[yourButton setBackgroundImage:yourImage forState:UIControlStateNormal];

[yourButton setBackgroundImage:[UIImage imageNamed:@"backgroungImage.png"] forState:UIControlStateNormal];
[self.view yourButton];
