I encountered the following problem: I want so connect my iPhone-App with a database

  • 0

I encountered the following problem:
I want so connect my iPhone-App with a database on a server. Therefore I use some (simple) .php files to manage the access to the DB. Inserting new data already works but I have some trouble to convert fetched data into a NSMutableArray :

NSURL *contentURL = [NSURL URLWithString:[kHOSTURL stringByAppendingString:kGETBarsURL]];
NSLog(@"URL : %@", contentURL);

NSData *contentData = [NSData dataWithContentsOfURL:contentURL];
NSLog(@"Data : %@", contentData);

NSError *e = nil;
NSMutableArray *jsonArray = [NSJSONSerialization JSONObjectWithData:contentData
                                                            options:kNilOptions
                                                              error:&e];
NSLog(@"JSON : %@", jsonArray);
NSLog(@"Error : %@", e);

Output is like this (I ‘XX’ and shortened ‘Data :’) :

2012-04-28 13:49:37.229 XX[14434:f803] URL : http://xx/getBars.php

If I open the page in a browser it looks like this:

[{"unique":"4","Name":"Test","Details":"ThisIsATest"},
 {"unique":"5","Name":"Test","Details":"ThisIsATest"},
 {"unique":"6","Name":"Test","Details":"ThisIsATest"},
 {"unique":"7","Name":"Test","Details":"ThisIsATest"},
 {"unique":"8","Name":"Test","Details":"ThisIsATest"},
 {"unique":"9","Name":"Test","Details":"ThisIsATest"},
 {"unique":"10","Name":"Test","Details":"ThisIsATest"}]

I’ve also tried other options in NSJSONSerialization but that did not work 🙁 Can anybody help me here ?

    It’s pretty obvious that you indeed have ‘garbage’ at the end. You have a JavaScript block that although is not visible in the browser, it’s still returning from your php script. Remove that and you should be good to go.
