我试图使用以下代码设置 UIBarButtonItem 的色调颜色，但我得到的只是一个黑色按钮。有没有一种方法可以在不需要使用自定义图像的情况下完成此任务？

[[UIBarButtonItem appearance] SetTintColor:[UIColor clearColor]]:

I am trying to set the tint color for a UIBarButtonItem using the following code, but all I get is a black button. Is there a way to accomplish this without the need to use custom images?

[[UIBarButtonItem appearance] SetTintColor:[UIColor clearColor]]:

使用按钮创建自定义 UIBarButtonItem

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:buttonImage forState:UIControlStateNormal];

//set the frame of the button to the size of the image (see note below)
button.frame = CGRectMake(0, 0, 24, 24);
button.backgroundColor=[UIColor clearColor];    
//create a UIBarButtonItem with the button as a custom view
UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];

create a custom UIBarButtonItem with a button

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:buttonImage forState:UIControlStateNormal];

//set the frame of the button to the size of the image (see note below)
button.frame = CGRectMake(0, 0, 24, 24);
button.backgroundColor=[UIColor clearColor];    
//create a UIBarButtonItem with the button as a custom view
UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];
