SDWebImage issues: Cocoa error 513 and Unrecognized selector send to instance

Question

I have implemented the SDWebImage exactly as the description (link) said using xcode 5, and it gives me no errors. This is what the piece of code looks like:

CustomCell *customcell = [self.tableView cellForRowAtIndexPath:[NSIndexPath indexPathForItem:(currentIndexPath) inSection:0]];
    Model *model = self.products[currentIndexPath];
    NSString *productImageNumber = model.productImageNumber;
    NSString *imageUrlString = [NSString stringWithFormat:@"http://www.imagine-app.nl/ProductImages/%@%@",productImageNumber,@".jpg"];
    [customcell.imageView setImageWithURL:[NSURL URLWithString:imageUrlString]
                   placeholderImage:[UIImage imageNamed:@"placeholder-square.jpg"]];

But when I run the app, and I press the button that uses the SDWebImage, I get two errors:

!!!!! Error creating directory /var/mobile/Library/Logs/CrashReporter/DiagnosticLogs/Photos/Process: The operation couldn’t be completed. (Cocoa error 513.) !!!!

and

unrecognized selector sent to instance 0x1752ea90

I can't figure out where they come from and neither how to solve them because, as mentioned, Xcode gives me no error or issue when I'm editing my code.

I'm a beginner so I may be missing out something simple, bus as mentioned, It is not the implementation of the SDWebImage that causes this, because I checked it numerous times and everything appeared to be right.

Does anybody have an idea how to solve this? thank you very much in advance!

Try to add exception breakpoint and see on which line the app crashes. — Valent Richie, Jun 28 '13 at 09:39
I did! everything works just fine. as soon as it gets to the setImageWithUrl:placeHolderImage it crashes. — Joris416, Jun 28 '13 at 09:47
Have you imported the UIImageView+WebCache.h header? Also check if the imageView property of the cell is really there and valid. — Valent Richie, Jun 28 '13 at 09:50
yes I have implemented them. strange thing about that is, the documentation (see link in question) tells me to do it like this: `#import `, but I have to do it like this: `#import "SDWebImage.framework/Headers/UIImageView+WebCache.h"`. that makes sense to me because that is the 'way to come there', but maybe it shouldn't be like this? The image view is also there and valid. it's a UIImageView I placed in a customCell. — Joris416, Jun 28 '13 at 09:55
yes it does. sorry for the late response. All these little things actually seem to be correct. maybe it is the fact that I can't implement the header as supposed to?? — Joris416, Jun 28 '13 at 11:07

The issue is that the SDWebImage .m files are not added in the target membership. Try to add those files under Build Phases > Compile Sources.

If you are also adding the MKAnnotationView+WebCache files, you need to include MapKit.framework under Link Binary With Libraries section.
