自定义UIBarButtonItem的文本

需要给UIBarButtonItem设置标题

代码如下：

UIButton* backToRecent = [UIButton buttonWithType:UIButtonTypeCustom];
[backToRecent setImage:[UIImage imageNamed:@"back.png"]forState:UIControlStateNormal];

[backToRecent addTarget:self action:@selector(backToRecent) forControlEvents:UIControlEventTouchUpInside];
[backToRecent setFrame:CGRectMake(0, 0, 60, 30)];

UIBarButtonItem* backButtonItem = [[UIBarButtonItem alloc]initWithCustomView:backToRecent];
[backButtonItem setTitle:@"Recent"];
partViewController.navigationItem.leftBarButtonItem = backButtonItem;
[backButtonItem release];

但是按钮显示后，没有recent文本。

试试我提供的方法

   UIBarButtonItem * backButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Recent" style:UIBarButtonItemStyleBordered target:self action:@selector(backToRecent)];
    self.navigationItem.leftBarButtonItem = backButtonItem;

应该在UIButton设置标题 , 不是在UIBarButtonItem

[backToRecent setTitle:@"Recent" forState:UIControlStateNormal];

而且不鼓励让变量和方法同名

[backToRecent addTarget:self action:@selector(backToRecent) forControlEvents:UIControlEventTouchUpInside];

这个不允许是因为你使用了：

[backToRecent setImage:[UIImage imageNamed:@"back.png"]forState:UIControlStateNormal];

换成用用这个试试：

[backToRecent setBackgroundImage:[UIImage imageNamed:@"back.png"]forState:UIControlStateNormal];
