How to NSMutableArray value pass from NSObject to UIViewController in ios ?

#import <Foundation/Foundation.h>
@interface InvitationList : NSObject

@property (nonatomic, retain) NSMutableArray *myObject;
@property (nonatomic, retain) NSMutableArray *displayObject;
@property (nonatomic, retain) NSDictionary *dict;

@property (nonatomic, retain) NSString *event_id;
@property (nonatomic, retain) NSString *eventname_inv;
@property (nonatomic, retain) NSString *location_inv;
@property (nonatomic, retain) NSString *date_inv;
@property (nonatomic, retain) NSString *image_url;
@property(nonatomic,assign) NSMutableData *receivedData;
-(void)fnPost:(NSString*)pStrVale;
-(NSString *)postMethos;
-(NSMutableArray *)postMethods;

@end
