更改导航项后退按钮标题

Question

如何在不同的东西上更改< Wish list 按钮？

Answer 1

如果有错误可以使用下面的代码告诉我

-(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;

} -（无效）翻转视图 { }

Answer 2

试试这个，

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)
}
