Answer 1

probar este método:

-(UIImage *)drawImage:(UIImage*)profileImage withBadge:(UIImage *)badge 
{ 
    UIGraphicsBeginImageContextWithOptions(profileImage.size, NO, 0.0f); 
    [profileImage drawInRect:CGRectMake(0, 0, profileImage.size.width, profileImage.size.height)]; 
    [badge drawInRect:CGRectMake(0, profileImage.size.height - badge.size.height, badge.size.width, badge.size.height)]; 
    UIImage *resultImage = UIGraphicsGetImageFromCurrentImageContext(); 
    UIGraphicsEndImageContext(); 
    return resultImage; 
} 

Usted puede utilizarlo por:

UIImage *myBadgedImage = [self drawImage:profileImage withBadge:badgeImage];

Prueba esto:

CGFloat scale = [self currentScale]; 
if (scale > 1.5) 
    UIGraphicsBeginImageContextWithOptions(view.frame.size, NO, scale); 
else 
    UIGraphicsBeginImageContext(view.frame.size); 

[image1 drawInRect:CGRectMake(0, 0, w1, h1)]; 
[image2 drawInRect:CGRectMake(0, 0, w2, h2)]; 

UIImage* screenshot = UIGraphicsGetImageFromCurrentImageContext(); 
UIGraphicsEndImageContext();
