Getting crashed when NSdictionary or NSString values into UILABEL - iphone

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

Answer 1

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.

Answer 2

Are you sure that your object is of NSString class?
Try putting in something like:
if([[dict4 objectForKey:#"temperature"] isKindOfClass:[NSString class]])
NSLog(#"lalala");
If it does not get logged to the console it means that your object is not an NSString and you could try something like:
temperatureLabel.text = [NSString stringWithFormat:#"%#", [dict4 objectForKey:#"temperature"]];
You should change the %# according to the kind of object you have stored in your dictionnary.

Answer 3

Your dictionary contains an NSNumber instance and you are assigning that to a property of type NSString. The crash message is your tip off there. Use stringValue or some other way to get the number's data into string form.
