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.

Is it a pattern? Create a bitmap image context, clip the context to your mask, draw image, create image from your bitmap context — nielsbot, Apr 05 '13 at 12:18

Show your code. Otherwise, there's no way to know why it's not working. — omz, Apr 05 '13 at 12:53

Are you assigning the value of

 [UIColor colorWithPatternImage:maskedImage];

to anything? Like...

  self.maskedView.backgroundColor = [UIColor colorWithPatternImage:maskedImage];

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];
