再升級了iOS 11之后發(fā)現(xiàn)導(dǎo)航欄返回圖片沒有居中, 并且下方還有一條線
解決方法如下:
UIImage *backImage = [[UIImage imageNamed:@"btn_back_normal"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(-100000, 0) forBarMetrics:UIBarMetricsDefault];
self.navigationBar.backIndicatorImage = backImage;
self.navigationBar.backIndicatorTransitionMaskImage = backImage;
