Just for information, i'm a newbie in Xcode Dev.
I have a problem with displaying data from a web service in a UITableView.
I use ASIHttpRequest to construct a HTTP request to get JSON data from a Web server. My request is constructed like this (with a JSON parameter and implemented in viewDidLoad methods) :
NSString *jsonString = @"login";
NSString *URL = @"MyURL";
NSURL *filactuURL = [NSURL URLWithString:URL];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:filactuURL];
[request setRequestMethod:@"POST"];
[request addRequestHeader:@"User-Agent" value:@"ASIHTTPRequest"];
[request addRequestHeader:@"Content-Type" value:@"application/json"];
[request appendPostData:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];
[request setDelegate:self];
[request startAsynchronous];
Then, I get the response with this code :
-(void) requestFinished: (ASIHTTPRequest *) request {
NSString *theJSON = [request responseString];
SBJsonParser *parser = [[SBJsonParser alloc] init];
id message = [parser objectWithString:theJSON error:nil];
if ([message isKindOfClass:[NSDictionary class]])
{
//Not used
}
else if ([message isKindOfClass:[NSArray class]])
{
for(int i = 0; i < [message count]; i++)
{
for (NSDictionary *dic in message) {
Message *messsage = [[Message alloc] init];
messsage.expediteur = [dic objectForKey:@"expediteur"];
messsage.titre = [dic objectForKey:@"titre"] ;
messsage.date = [dic objectForKey:@"date"] ;
messsage.contenu = [dic objectForKey:@"contenu"] ;
[tableau addObject:messsage];
[messsage release];
}
}
[theJSON release];
}
}
The server send me JSON data, I parse it using SBJSon and I populate a Message object. This object will be used to populate cells of a TableView. After getting the response, here's the problem : cells are empty, but the app doesn't crash and i got no error.
I've tried with hard stored JSON data, it works fine, the cells are filled.
Thanks for helping
