Create 1 image from masked image in ios

Question

I have a image and i mask this image with another image to make shape.
I just want to change the view background color of Masked image.
I am using [UIColor colorWithPatternImage:maskedImage];
But its not working.
Please suggest me how to merge or create Masked 2 images in 1 image so colorWithPatternImage will work.

Answer 1

UIImage *originalImage = [UIImage imageNamed:@"original.png"]; //my background image
UIImage *maskedImage       = [UIImage imageNamed:@"maskedImage.png"]; //my masked image

CGSize newSize = CGSizeMake(width, height);
UIGraphicsBeginImageContext( newSize );


[originalImage drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];


[maskedImage drawInRect:CGRectMake(0,0,newSize.width,newSize.height) blendMode:kCGBlendModeNormal alpha:0.6];

UIImage *newMaskedBackGroundImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

then use this newMaskedBackGroundImage, ex. [UIColor colorWithPatternImage:newMaskedBackGroundImage];
