更改导航项后退按钮标题

Question

如何更改< Wish list按钮上的其他内容？

Answer 1

如果有任何错误，您可以使用以下代码，然后告诉我

-（void）viewWillAppear：（BOOL）动画{[super viewWillAppear：YES];

UIBarButtonItem *flipButton = [[UIBarButtonItem alloc]
                               initWithTitle:@"Pending"
                               style:UIBarButtonItemStyleBordered
                               target:self
                               action:@selector(flipView)];

self.navigationItem.leftBarButtonItem = flipButton;

}-（void）flipView {}

Answer 2

尝试这个，

let newBackButton = UIBarButtonItem(title: "SomeOtherTitle", style: UIBarButtonItemStyle.Bordered, target: self, action: "back:")
self.navigationItem.leftBarButtonItem = newBackButton;

func back(sender: UIBarButtonItem) {
    self.popViewControllerAnimated(true, completion: nil)
}
