Question

I am trying to change ShareKit API code of attachment to this code below:

dialog.attachment = [NSString stringWithFormat:@"{\"name\":\"%@\",\"href\"
:\"%@\",\"media\":[{\"type\":\"image\",\"src\":\"http://example.com/example.png\"
,\"href\": \"http://example.com/\"}]} ",item.title == nil ? SHKEncodeURL(item.URL) 
SHKEncode(item.title),SHKEncodeURL(item.URL)];

Xcode Keeps telling me prefix error.
What am I missing?

Answer 1

You are missing an colon in the three-way conditional;

The original code looks like this:

dialog.attachment = [NSString stringWithFormat:@"{\"name\":\"%@\",\"href\"
:\"%@\",\"media\":[{\"type\":\"image\",\"src\":\"http://example.com/example.png\"
,\"href\": \"http://example.com/\"}]} ",item.title == nil ? SHKEncodeURL(item.URL) 
SHKEncode(item.title),SHKEncodeURL(item.URL)];

Change it to this

dialog.attachment = [NSString stringWithFormat:@"{\"name\":\"%@\",\"href\"
:\"%@\",\"media\":[{\"type\":\"image\",\"src\":\"http://example.com/example.png\"
,\"href\": \"http://example.com/\"}]} ",item.title == nil ? SHKEncodeURL(item.URL): 
SHKEncode(item.title),SHKEncodeURL(item.URL)];

The error is at the end of the third line.

You should have seen this in the XCode editor, with a little yellow charat under the position where the error is.
