With DRImagePlaceholderHelper you can easily create UIImage placeholder like this:

At first you have to import the Framework

    #import "DRImagePlaceholderHelper.h"

To get a placeholder image simply do: (100x100)

    UIImage *placeholderImage = [[DRImagePlaceholderHelper sharedInstance] placerholderImageWithSize:CGSizeMake(100,100)];

Or fill a UIImageView

    [imageView fillWithPlaceholderImage]; 

There are also options to customize the fill color & the text inside the image

For more information take a look at the example project.
