objectForKey not returning anything - objective-c

Question

-(NSMutableDictionary *)request:(NSString *)requestString {
NSString *filepath = [[NSBundle mainBundle] pathForResource:requestString ofType:#"xml"];
NSError *error = nil;
respString = [NSString stringWithContentsOfFile:filepath usedEncoding:nil error:&error];
NSLog(#"Ping xml");
tempDict = [[NSMutableDictionary alloc] initWithDictionary:[parser readXMLString:respString]];
NSLog(#"%#",tempDict);
return tempDict;
}
Until there, everything is ok, the NSLog is showing that there are 2 objects and keys in the tempDict.
But then:
-(int) authenticateUser {
NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] initWithDictionary:[self request:#"login"]];
if ([[dictionary objectForKey:#"sessionId0"] isEqualToString:#"-1"] ) {
//Some code
}
else {
cError = 1;
NSLog(#"%#",[dictionary objectForKey:#"sessionId0"]);
appDelegate.sessionId = [dictionary objectForKey:#"sessionId0"];
}
[dictionary release];
return cError;
}
At the last else, where cError is 1, NSLog outputs nil for that object.
(NSLog for the entire dictionary also outputs nil)

Answer 1

Place this code in your and see what the output is for dict object...
-(int) authenticateUser {
NSDictionary* dict = (NSDictionary *)[self request:#"login"];
NSLog(#"Dictionary %#",dict);
NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] initWithDictionary:[self request:#"login"]];
if ([[dictionary objectForKey:#"sessionId0"] isEqualToString:#"-1"] ) {
//Some code
}
else {
cError = 1;
NSLog(#"%#",[dictionary objectForKey:#"sessionId"]);
appDelegate.sessionId = [dictionary objectForKey:#"sessionId"];
}
[dictionary release];
return cError;
}
