解决iOS中tabBarItem图片默认颜色的问题(指定代码渲染模式为以原样模式的方式显示出来)

解决办法:指定图片的渲染模式(imageWithRenderingMode为:UIImageRenderingModeAlwaysOriginal模式)

代码示例:

//image

 childController.tabBarItem.image = [[UIImage imageNamed:imageName]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

//title

NSMutableDictionary *dict = [NSMutableDictionary dictionary];

dict[NSForegroundColorAttributeName] = [UIColor orangeColor];

//指定选中下的titile的颜色

[childController.tabBarItem setTitleTextAttributes:dict forState:UIControlStateSelected];
