问题描述

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。

解决方案

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;

解决方案二：
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];
