tabbar ios

tabBar圖片被tintColor填充問題解決：
nav.tabBarItem.image = [[UIImageimageNamed:@“barImage”]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

nav.tabBarItem.selectedImage [[UIImag imageNamed:@"barImgaeSelected"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

消息角標：self.navigationController.tabBarItem.badgeValue = @"新消息";
