send many NSURLConnection requests and get response in connectionDidFinishLoading - iphone

Question

I'm trying to send many asynchronous request to php file that shows my data as json code and in the response I parse the json so I added the following in ViewDidload:
NSURLRequest *aboutRequest = [self getDataFromServer:#"http://al-awal.com/Rashad/iPhonePhp/about.php"];
aboutConn = [[NSURLConnection alloc] initWithRequest:aboutRequest delegate:self];
NSURLRequest *wisdomRequest = [self getDataFromServer:#"http://al-awal.com/Rashad/iPhonePhp/wisdomtoday.php"];
wisdomConn = [[NSURLConnection alloc] initWithRequest:wisdomRequest delegate:self];
then
-(NSURLRequest *) getDataFromServer:(NSString *)phpUrl{
responseData = [NSMutableData data];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:phpUrl]];
return request;
}
then I added:
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
sqlite3 *database;
if(sqlite3_open([[rashadDB databasePath] UTF8String], &database) == SQLITE_OK) {
if (connection == aboutConn) {
NSLog(#"get from table about");
SBJsonParser *parser = [[SBJsonParser alloc] init];
NSString *json_string = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSArray *statuses = [parser objectWithString:json_string error:nil];
for (NSDictionary *status in statuses)
{
NSString *sAboutID = [status objectForKey:#"ID"];
NSString *sPhone1 = [status objectForKey:#"Phone1"];
NSString *sPhone2 = [status objectForKey:#"Phone2"];
NSString *sJawal = [status objectForKey:#"Jawal"];
NSString *sFax = [status objectForKey:#"Fax"];
NSString *sWebSite = [status objectForKey:#"WebSite"];
NSString *sEmail = [status objectForKey:#"Email"];
NSString *sAddress = [status objectForKey:#"Address"];
int sAboutID2 = [sAboutID intValue];
NSLog(#"in server, aboutID = %d, Phone1 = %#, Phone2 = %#, Jawal = %#, Fax = %#, WebSite = %#, Email = %#, Address = %#",sAboutID2, sPhone1, sPhone2, sJawal, sFax, sWebSite, sEmail, sAddress);
sqlite3_exec(database, [[NSString stringWithFormat:#"INSERT OR ABORT INTO About VALUES(%d, '%#', '%#', '%#', '%#', '%#', '%#', '%#')",sAboutID2, sPhone1, sPhone2, sJawal, sFax, sWebSite, sEmail, sAddress] UTF8String], NULL, NULL, NULL);
sqlite3_exec(database, [[NSString stringWithFormat:#"UPDATE About set Phone1 = '%#', Phone2 = '%#', Jawal = '%#', Fax = '%#', WebSite = '%#', Email = '%#', Address = '%#' Where aboutID = %d", sPhone1, sPhone2, sJawal, sFax, sWebSite, sEmail, sAddress, sAboutID2] UTF8String], NULL, NULL, NULL);
}
} else if (connection == wisdomConn) {
NSLog(#"get from table wisdoms");
SBJsonParser *parser = [[SBJsonParser alloc] init];
NSString *json_string = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSArray *statuses = [parser objectWithString:json_string error:nil];
for (NSDictionary *status in statuses)
{
NSString *sWisdomTodayID = [status objectForKey:#"ID"];
NSString *sContent = [status objectForKey:#"Content"];
NSString *sAuthorName = [status objectForKey:#"AuthorName"];
NSString *sDateCreate = [status objectForKey:#"DateCreate"];
NSString *sEnable = [status objectForKey:#"Enable"];
int sWisdomTodayID2 = [sWisdomTodayID intValue];
int sEnable2 = [sEnable intValue];
NSLog(#"wisdomTodayID = %#, Content = '%#', AuthorName = '%#', DateCreate = '%#', Enable = %#", sWisdomTodayID, sContent, sAuthorName, sDateCreate, sEnable);
sqlite3_exec(database, [[NSString stringWithFormat:#"INSERT OR ABORT INTO WisdomToday VALUES(%d, '%#', '%#', '%#', %d)",sWisdomTodayID2, sContent, sAuthorName, sDateCreate, sEnable2] UTF8String], NULL, NULL, NULL);
sqlite3_exec(database, [[NSString stringWithFormat:#"UPDATE WisdomToday set Content = '%#', AuthorName = '%#', DateCreate = '%#', Enable = %d Where wisdomTodayID = %d", sContent, sAuthorName, sDateCreate, sEnable2, sWisdomTodayID2] UTF8String], NULL, NULL, NULL);
}
}
} // sqlite3 open end
sqlite3_close(database);
}
the first if condition --> if(connection == aboutConn) works ok with me and I got my output but the other if condition --> if (connection == wisdomConn) only gives me this output NSLog(#"get from table wisdoms"); and not go throw the for loop.
Is there are any wrong in my code?

Answer 1

You are not closing braces properly...
Before opening the brace for else - if condition you should close the brace for if_condition..

Answer 2

Some of your relevant code is missing (the NSConnectionDataDelegate methods). But it would seem that you are using one instance variable, responseData, to build up both return values. This would mean that some times you would get the faster response data only; and other times you would get mixed data in the same NSMutableData object.
