Extract image from URL

The url is:

https://api.url2png.com/v3/P4DE5D1C99D8EF/7bbb6e0d1b74fb0ae1d4f18b06320096/400x400/abc.com

I want to get above image into to a UIImage. I tried this: 

NSURL *urlString = [NSURL URLWithString:@"https://api.url2png.com/v3/P4DE5D1C99D8EF/7bbb6e0d1b74fb0ae1d4f18b06320096/400x400/abc.com"];

NSData *imageData = [[NSData alloc]initWithContentsOfURL:urlString];
UIImage *img = [UIImage imageWithData:imageData];

But it seems this doesn't work. The url doesn't have an file extension like .png or .jpg. Is is possible to extract the image from this kind of URL?

You were close, what you're going to want to do is UIImagePNGRepresentation in the case of this particular image (because the image you linked is actually .png) to basically convert the data to a workable image. If you are trying to use a .jpg image use UIImageJPEGRepresentation.

NSURL *urlString = [NSURL URLWithString:@"https://api.url2png.com/v3/P4DE5D1C99D8EF/7bbb6e0d1b74fb0ae1d4f18b06320096/400x400/abc.com"];
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation([UIImage imageWithData:[NSData dataWithContentsOfURL:urlString]])];
UIImage *image = [UIImage imageWithData:imageData];

Or, if you're as big of a fan on one-liners as I am, you can use this:

UIImage *image = [UIImage imageWithData:UIImagePNGRepresentation([UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"https://api.url2png.com/v3/P4DE5D1C99D8EF/7bbb6e0d1b74fb0ae1d4f18b06320096/400x400/abc.com"]]])];
