问题描述

我得到了以下代码：

- (id)init {
  if (self = [super init]) {
      self.title = @"please wait";
      UIBarButtonItem *favorite = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"star.png"] style:UIBarButtonItemStylePlain target:self action:@selector(buttonFavoriteClicked:)];
      self.navigationItem.rightBarButtonItem = favorite;
  }

  return self;
}

但我的按钮看起来仍然像一个带有UIBarButtonItemStyleBordered的按钮

but my button looks still like a Button with UIBarButtonItemStyleBorderedalt text http://img693.imageshack.us/img693/1632/bildschirmfoto20100227ui.png

有没有办法在这个位置设置一个普通风格的按钮？

is there a way to set a button with plain style at this position?

推荐答案

在界面构建器中创建一个UIButton，使其看起来完全符合您的要求。在你的.h中创建一个插座：

Create a UIButton in interface builder, make it look like exactly what you want. Create an outlet for in in your .h:

IBOutlet UIButton * _myButton;

然后使用自定义视图将其设置为右侧栏按钮项，这将消除边框：

Then set it as your right bar button item using a custom view, which will eliminate the border:

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:_myButton];

这是因为UIButton是UIView的子类。

This works because UIButton is a subclass of UIView.
