推荐答案

我们在应用程序的工具栏中使用了一些特殊的按钮.我们按照以下方式进行.

We used some special button in tool bar in an application. We make it following way.

    UIButton* btnInfo = [UIButton buttonWithType:UIButtonTypeInfoLight];
[btnInfo addTarget:self action:@selector(verInfoBtnClicked:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *modalButton = [[UIBarButtonItem alloc] initWithCustomView:btnInfo];

这里要点是使用[[UIBarButtonItem alloc] initWithCustomView:btnInfo];方法.
