#import <CkoJsonObject.h> #import <NSString.h> CkoJsonObject *json = [[CkoJsonObject alloc] init]; NSString *jsonStr = @"{ \"id\": 1, \"name\": \"A green door\", \"tags\": [\"home\", \"green\"], \"price\": 125 }"; BOOL success = [json Load: jsonStr]; if (success != YES) { NSLog(@"%@",json.LastErrorText); return; } int numMembers = [json.Size intValue]; int i; for (i = 0; i <= numMembers - 1; i++) { NSString *name = [json NameAt: [NSNumber numberWithInt: i]]; NSString *value = [json StringAt: [NSNumber numberWithInt: i]]; NSLog(@"%@%@%@",name,@": ",value); int iValue = [[json IntAt: [NSNumber numberWithInt: i]] intValue]; NSLog(@"%@%@%d",name,@" as integer: ",iValue); } // Note: The StringAt method returns the value as a string regardless of the type. // If the value is a JSON array (such as for ["home", "green"]), then the JSON encoding // of the entire array is returned. // The IntAt method returns the value as an integer. If the value does not convert to // an integer, then 0 is returned |
