Usando NSJSONSerialización para analizar JSON
Han ocurrido demasiadas discusiones sobre esto y, sin embargo, no puedo encontrar la manera de resolver mi problema.
Aquí están los datos JSON que obtengo de WorldWeatherOnline. El JSON es válido. Pero no puedo averiguar cómo analizarlo. Este es mi código, seguido por el JSON. ¡Por favor ayuda!
NSError* errorInfo;
NSDictionary *parsedJSON = [NSJSONSerialization JSONObjectWithData:self.wwoWeatherData options:kNilOptions error:&errorInfo];
NSArray* temp = [parsedJSON objectForKey:@"temp_C"];
NSLog(@"%@", temp);
