ios - IOS自定义导航返回按钮不起作用

Question

我在我的视图控制器中尝试了以下操作。没用。我正在使用情节提要。

[super viewDidLoad];

UIImage *backImage = [UIImage imageNamed:@"Back.png"] ;
UIBarButtonItem *backButton=[[UIBarButtonItem alloc]initWithImage:backImage style:     (UIBarButtonItemStyleBordered) target:nil action:nil];
backButton.title=@"TEST";
[self.navigationItem setBackBarButtonItem:backButton];

请帮忙。谢谢。

Answer 1

尝试

[[UIBarButtonItem appearance] setBackButtonBackgroundImage:[UIImage imageNamed:@"someimage.png"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault].

Answer 2

试试这个，这将解决您的图像问题

UIImage *backImage = [[UIImage imageNamed:@"Back.png"]resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 5)];

[[UIBarButtonItem appearance] setBackButtonBackgroundImage:backImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

愿这能解决你的问题。

快乐编码:)
