如何以编程方式向UINavigationBar添加按钮?

How to add a button to UINavigationBar programmatically?

推荐答案

设置右键按钮的示例代码 NavigationBar 上。

UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"Done" 
    style:UIBarButtonItemStyleDone target:nil action:nil];
UINavigationItem *item = [[UINavigationItem alloc] initWithTitle:@"Title"];
item.rightBarButtonItem = rightButton;
item.hidesBackButton = YES;
[bar pushNavigationItem:item animated:NO];

但通常你会有一个 NavigationController ,让你写:

But normally you would have a NavigationController, enabling you to write:

UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"Done"
    style:UIBarButtonItemStyleDone target:nil action:nil];
self.navigationItem.rightBarButtonItem = rightButton;
