Answer 1

Begin from iOS 7, you can choose to treat any of the images in your app as a template—or stencil—image. When you elect to treat an image as a template, the system ignores the image’s color information and creates an image stencil based on the alpha values in the image. UIImage has a new property named renderingMode The default rendering mode is UIImageRenderingModeAutomatic. From my experience it usually means template like image so when you init your image you need

UIImage *image = [UIImage imageNamed:@"someimage"];
UIImage *thisoneshouldbeused = [image imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal]

See Template Images in UIKit User Interface Catalog for more information

@Inertiatic has a great answer, use -imageWithRenderingMode:.

NSArray *images = @[@"[FIRST IMAGE]", @"[SECOND IMAGE]", …];
NSArray *selectedImages = @[@"[FIRST SELECTED IMAGE]", @"[SECOND SELECTED IMAGE]", …];

UITabBarController *tabBarController = (id)self.window.rootViewController;

for (NSInteger i = 0; i < tabBarController.tabBar.items.count; ++i) {
    UITabBarItem *item in tabBarController.tabBar.items[i];

    item.image = [[UIImage imageNamed:images[i]] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    item.selectedImage = [[UIImage imageNamed:selectedImages[i]] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
}
