Question

如何以编程方式向 UINavigationBar 添加按钮？

Answer 1

在 NavigationBar 上设置 rightbutton 的示例代码。

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];

但通常您会有一个 NavigationController，使您能够编写:

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