解决方法
如果可能,您可以提供设置标签栏图像的方法吗？
我也遇到了同样的问题,并使用UIImageRenderingModeAlwaysOriginal修复它：
UIImage *image = // Your tab bar item image
UIImage *selected = // Your selected tab bar item image
image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
selected = [selected imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
controller.tabBarItem = [[UITabBarItem alloc] initWithTitle:title
image:image
selectedImage:selected];
干杯!
