  最近将Xcode的Base SDK升级到iOS8.0以后，发现使用的系统级的UITabBar，图标在selected状态都变成蓝色，很郁闷。
  查找资料后发现UITabBarItem.h里面说的很清楚，
  /* These methods are now deprecated. Please use -initWithTitle:image:selectedImage:.*/
  - (void)setFinishedSelectedImage:(UIImage *)selectedImage withFinishedUnselectedImage:(UIImage *)unselectedImage NS_DEPRECATED_IOS(5_0,7_0,"Use initWithTitle:image:selectedImage: or the image and selectedImage properties along with UIImageRenderingModeAlwaysOriginal");
  UIImageRenderingModeAlwaysOriginal（始终绘制图片原始状态）是关键，即需要对图片多做一次小小的处理，即

 //构造TabBarItem：title-标题、image-图片、selectedImage-选中时图片        - (UITabBarItem *)itemWithTitle:(NSString *)title image:(UIImage *)image selectedImage:(UIImage *)selectedImage        {                //始终绘制图片原始状态                image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];                selectedImage = [selectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];                UITabBarItem *tabBarItem = [[UITabBarItemalloc]initWithTitle:titleimage:imageselectedImage:selectedImage];                return tabBarItem;        }

这样，在构建TabBarItem时，直接调用这个方法就可以了。
