ios 11導航欄替換返回按鈕圖片,隱藏文字

//親測成功，關鍵設置UIOffsetMake(-200, -10)，在豎直方向上的偏移值，你也能夠本身稍微調整一下，根據本身返回按鈕圖片大小；

if (IOS11_OR_LATER) {// 若是iOS 11走else的代碼，系統本身的文字和箭頭會出來

        [[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(-200, -10) forBarMetrics:UIBarMetricsDefault];

        UIImage *backButtonImage = [[UIImage imageNamed:@"return_image"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

        [UINavigationBar appearance].backIndicatorImage = backButtonImage;

        [UINavigationBar appearance].backIndicatorTransitionMaskImage =backButtonImage;

       

    }else

    {

        [[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(-200, 0) forBarMetrics:UIBarMetricsDefault];

        UIImage *image = [[UIImage imageNamed:@"return_image"] imageWithRenderingMode:(UIImageRenderingModeAlwaysOriginal)];

        [[UIBarButtonItem appearance] setBackButtonBackgroundImage:[image resizableImageWithCapInsets:UIEdgeInsetsMake(0, image.size.width, 0, 0)] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

    }
