How can I set UIBarButtonItem's color to green? I'm using iOS 4, there is no tint property. please help me.

推荐答案

在iOS 4中：

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setBackgroundImage:[UIImage imageNamed:@"green.png"] forState:UIControlStateNormal];
button.frame=CGRectMake(0.0, 100.0, 60.0, 30.0);
[button setTitle:@"Green" forState:UIControlStateNormal];
[button addTarget:self action:@selector(yourAction) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *myButton = [[UIBarButtonItem alloc] initWithCustomView:button];

在这里你需要一个绿色图像来做这个，你正在创建一个带有这个图像和设置的自定义按钮它作为UIBarButtonItem的视图。

Here you need a green image for doing this, you are creating a custom button with this image and set it as the view of UIBarButtonItem.

在iOS 5中你可以使用：

In iOS 5 you can use:

[[UIBarButtonItem appearance] setTintColor:[UIColor greenColor]];
