如何在iPhone中添加按钮图像.

Answer 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];

Answer 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];

祝好运
