我想加入自定义后退按钮-我可以使用以下方法获得上述结果

self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"back-btn"] style:UIBarButtonItemStylePlain target:nil action:nil];

但是如何删除 native 的蓝色按钮?

最佳答案

使用以下代码隐藏后退箭头:

self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"back-btn"]
                                                                         style:UIBarButtonItemStylePlain
                                                                        target:nil
                                                                        action:nil];

if ([UINavigationBar instancesRespondToSelector:@selector(setBackIndicatorImage:)]) {
    [[UINavigationBar appearance] setBackIndicatorImage:[[UIImage alloc] init]];
    [[UINavigationBar appearance] setBackIndicatorTransitionMaskImage:[[UIImage alloc] init]];
}
