如何分配UIImageView PlaceHolderImage

Question

I am trying to assign a placeholderimage in my UIImageView but am getting this error

No visible @interface for 'UIImage' declares the selector 'placeholderImage:'

This is how I thought I might be able to do it... obviously wrong but anyway this is what the code looks like.

firstSpaceImageView.image = [[UIImage imageNamed:@"CA.png"] placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

any help would be greatly appreciated.

Answer 1

-[UIImageView setImageWithURL:placeholderImage:] is part of AFNetworking . You need to include it to get this method.

Answer 2

There is no property called placeholderImage on UIImage (or on UIImageView). If you want to make your own placeholder solution, this question will help.

PS: Even if there was such a property, the setter method would be setPlaceholderImage: rather than placeholderImage
