Question

-(void) httpDataDidFinishLoadingWithData:(NSData *)theData
{
    m_activityLoaded=NO;
    temp=[[NSString alloc] initWithData:[dataLoader httpData]
                               encoding:NSUTF8StringEncoding];
    NSLog(@"TEMP IS TEMP %@", temp);

    NSDictionary *dict = [[NSDictionary alloc]init];
    dict = [[temp JSONValue] objectForKey:@"location"];

    NSDictionary *dict1 = [[NSDictionary alloc]init];
    dict1 = [[temp JSONValue] objectForKey:@"wind"];


    NSDictionary *dict2 = [[NSDictionary alloc]init];
    dict2 = [dict1 objectForKey:@"direction"];

    NSDictionary *dict3 = [[NSDictionary alloc]init];
    dict3 = [[temp JSONValue] objectForKey:@"atmosphere"];

    NSDictionary *dict4 = [[NSDictionary alloc]init];
    dict4 = [[temp JSONValue] objectForKey:@"condition"];
    NSDictionary *dict5 = [[NSDictionary alloc]init];
    dict5 = [dict4 objectForKey:@"text"];
    NSDictionary *dict6 = [[NSDictionary alloc]init];
    dict6 = [dict4 objectForKey:@"code"];
    NSDictionary *dict7 = [[NSDictionary alloc]init];
    dict7 = [dict4 objectForKey:@"temperature"];

    temperatureLabel.text = [dict4 objectForKey:@"temperature"];
}

Crash occurs at temperatureLabel.text = [dict4 objectForKey:@"temperature"];

I dont know man, Data is exactly printed in the console, but crashing at UILABEL(temperatureLabel). Help me out, thanks in advance

if you look at the error you are getting it is telling you that the object return for the key temperature is not a NSString or NSDictionary but a NSNumber.

Give this a try:

-(void) httpDataDidFinishLoadingWithData:(NSData *)theData {
    m_activityLoaded=NO;
    temp=[[NSString alloc] initWithData:[dataLoader httpData]
                               encoding:NSUTF8StringEncoding];
    NSLog(@"TEMP IS TEMP %@", temp);

    NSDictionary *dict = [[temp JSONValue] objectForKey:@"location"];
    NSDictionary *dict1 =  [[temp JSONValue] objectForKey:@"wind"];
    NSDictionary *dict2 = [dict1 objectForKey:@"direction"];

    NSDictionary *dict3 = [[temp JSONValue] objectForKey:@"atmosphere"];
    NSDictionary *dict4 = [[temp JSONValue] objectForKey:@"condition"];
    NSDictionary *dict5 = [dict4 objectForKey:@"text"];
    NSDictionary *dict6 =  [dict4 objectForKey:@"code"];
    NSNumber *temperature = [dict4 objectForKey:@"temperature"];

    temperatureLabel.text = [NSString stringWithFormat:@"%@", temperature]; 
}

You might want to look at NSNumberFormatter for formatter the temperature with something like: °F or °C.
