Question

When i pass an NSString as object for a key in an NSMutableDictionary it seems to contain escape characters as regular characters. How can I remove them? I have tried stringByReplacingOccurrencesOfString:@”\” withString:@”” byt it does not work.

Here is my code and output:

Code:

NSString* fql1 = [NSString stringWithFormat:@"SELECT page_id FROM place WHERE distance(latitude,longitude,\"%@\",\"%@\") < 1500 AND checkin_count > 5", latitude, longitude];
    NSString* fql2 = [NSString stringWithFormat:@"SELECT author_uid, post_id, timestamp, tagged_uids, message FROM checkin WHERE page_id IN (select page_id from #PlaceQuery)"];
    NSString* fql = [[NSString stringWithFormat:@"{\"PlaceQuery\":\"%@\",\"CheckInQuery\":\"%@\"}",fql1,fql2] stringByReplacingOccurrencesOfString:@"\\" withString:@""];


NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObject:fql forKey:@"queries"];

NSLog(@"%@", fql);
NSLog(@"%@", params);

Output from NSLog(@”%@”, fql):

{“PlaceQuery”:”SELECT page_id FROM place WHERE distance(latitude,longitude,”37.331693″,”-122.030457″) < 1500 AND checkin_count > 5″,”CheckInQuery”:”SELECT author_uid, post_id, timestamp, tagged_uids, message FROM checkin WHERE page_id IN (select page_id from #PlaceQuery)”}

Output from NSLog(@”%@”, params):

{
queries = “{\”PlaceQuery\”:\”SELECT page_id FROM place WHERE distance(latitude,longitude,\”37.331693\”,\”-122.030457\”) < 1500 AND checkin_count > 5\”,\”CheckInQuery\”:\”SELECT author_uid, post_id, timestamp, tagged_uids, message FROM checkin WHERE page_id IN (select page_id from #PlaceQuery)\”}”;
}

I have been searching for hours for a solution so thanks A LOT in advance 😉

This turned out to be an issue about permissions… yes, embarrasing…
What confused me was that the escape characters was in the response output…
