JSON

Question

पार्स करने के लिए NSJSONSerialization का उपयोग करके इस पर बहुत सी चर्चाएं हुई हैं और फिर भी मैं यह नहीं समझ सकता कि मेरी समस्या का समाधान कैसे करें।

यहां वर्ल्डसदरऑनलाइन से प्राप्त JSON डेटा है। जेएसओएन मान्य है। लेकिन मैं यह समझ नहीं सकता कि इसे कैसे पार्स किया जाए। जेएसओएन के बाद यह मेरा कोड है। कृपया सहायता कीजिए!

NSError* errorInfo; 
NSDictionary *parsedJSON = [NSJSONSerialization JSONObjectWithData:self.wwoWeatherData options:kNilOptions error:&errorInfo]; 

NSArray* temp = [parsedJSON objectForKey:@"temp_C"]; 
NSLog(@"%@", temp);

Answer 1

आपका json कि आप पार्स एक शब्दकोश data नामित होता है। उस शब्दकोश के भीतर current_condition की एक सरणी है। जिन गुणों को आप ढूंढ रहे हैं उन्हें ढूंढने के लिए डेटा संरचनाओं के माध्यम से ड्रिलिंग रखें:

NSDictionary *data = [parsedJSON objectForKey:@"data"]; 
NSArray *currentConditions = [data objectForKey:@"current_condition"]; 
NSDictionary *condition = [currentConditions objectAtIndex:0]; 
NSString *tempC = [condition objectForKey:@"temp_C"];
