Please write this code in Appdelegate declare this property. After that SetValue your Dictionary Data

@property(strong,nonatomic)NSDictionary * dictFieldData;

Write this code My First NSObject class FieldData.M Create object in ViewdidLoad

 AppDelegate *appdelegate ((AppDelegate *)[[UIApplication sharedApplication] delegate]);

///set the field id
self.fieldId = [[appdelegate.dictFieldData SetValue:(NSString*) objectForKey:@"f_id"]intValue];

///Get the field id
self.siteId = [[appdelegate.dictSiteData Valueforkey:@"s_id"]intValue];
