Example of "CIMaskToAlpha" filter's usage.
CIContext *context = [CIContext contextWithOptions:nil];
UIImage *entryImage = [UIImage imageNamed:@"someImage.png"];
CIImage *image = [CIImage imageWithCGImage:[entryImage CGImage]];
CIFilter *filter = [CIFilter filterWithName:@"CIMaskToAlpha"];
[filter setValue:image forKey:kCIInputImageKey];
CIImage *result = [filter valueForKey:kCIOutputImageKey];
CGImageRef cgImage = [context createCGImage:result fromRect:[result extent]];
UIImage *newImage = [UIImage imageWithCGImage:cgImage scale:[entryImage scale] orientation:UIImageOrientationUp];

UIImage doesn't have a tint colour. UIImageView does. This little method returns a UIImage, tinted with a UIColor. It's useful for things like table icons, where the image view is read only. Means you don't have to create loads of PNGs in different colours.
-(UIImage *)imageWithTint:(UIImage *)image andTintColor:(UIColor *)tintColor {
UIImage *imageNew = [image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
UIImageView *imageView = [[UIImageView alloc] initWithImage:imageNew];
imageView.tintColor = tintColor;
UIGraphicsBeginImageContextWithOptions(imageView.bounds.size, NO, 0.0);
[imageView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *tintedImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
