UIBarButtonItem类目-返回一个有图片的导航栏按钮

/**
* 快速创建一个显示图片的item
*
* @param action 监听方法
*/
+ (UIBarButtonItem *)itemWithIcon:(NSString *)icon highIcon:(NSString *)highIcon target:(id)target action:(SEL)action;

+ (UIBarButtonItem *)itemWithIcon:(NSString *)icon highIcon:(NSString *)highIcon target:(id)target action:(SEL)action
{
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setBackgroundImage:[UIImage imageWithName:icon] forState:UIControlStateNormal];
[button setBackgroundImage:[UIImage imageWithName:highIcon] forState:UIControlStateHighlighted];
button.frame = (CGRect){CGPointZero, button.currentBackgroundImage.size};
[button addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];
return [[UIBarButtonItem alloc] initWithCustomView:button];
}

为UIBarButtonItem添加类目
使用：

// 左边按钮
self.navigationItem.leftBarButtonItem = [UIBarButtonItem itemWithIcon:@"navigationbar_friendsearch" highIcon:@"navigationbar_friendsearch_highlighted" target:self action:@selector(findFriend)];

// 右边按钮
self.navigationItem.rightBarButtonItem = [UIBarButtonItem itemWithIcon:@"navigationbar_pop" highIcon:@"navigationbar_pop_highlighted" target:self action:@selector(pop)];
