自定义导航栏上的导航项

Question

如图所示，我已成功通过代码自定义UINavigationController的navigationBar的背景：

UINavigationController *nav = ......
[[nav navigationBar] setBackgroundImage:[UIImage imageNamed:@"bg_daohang"] forBarMetrics:UIBarMetricsDefault];

现在，我想在navigationBar上自定义项目（在红色圆圈中）。是否可以这样做以及如何做到这一点？

Answer 1

UIButton *button =[UIButton buttonWithType:UIButtonTypeCustom];
button.frame=CGRectMake(0.0, 0, 60.0, 30.0);
[button setBackgroundImage:[UIImage imageNamed:@"logout.png"] forState:UIControlStateNormal];
[button setTitle:@"Logout" forState:UIControlStateNormal];
button.titleLabel.font = [UIFont boldSystemFontOfSize:13];

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

UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationItem.rightBarButtonItem= item;
[item release];
