GameKit framework ile ilgili bir sorunum var. Uygulamamda bir metin veya resim göndermek istiyorum. Şimdi, UIImagePicker'dan bir görüntü gönderdiğimde, iyi çalışıyor. Metin gönderdiğimde, resim içermeyen resimler için aynı UIAlertView gösterilmez. İşte .h geçerli:iPhone - bluetooth üzerinden görüntü ve metin gönderme hatası
#import <UIKit/UIKit.h>
#import <GameKit/GameKit.h>
@interface ViewController : UIViewController <GKPeerPickerControllerDelegate, GKSessionDelegate, UIActionSheetDelegate, UINavigationControllerDelegate, UIImagePickerControllerDelegate> {
GKSession *currentSession;
IBOutlet UITextField *txtMessage;
IBOutlet UIButton *connect;
IBOutlet UIButton *disconnect;
GKPeerPickerController *picker;
UIImagePickerController *imgPicker;
BOOL isText;
UIImage *_image;
}
@property (nonatomic, retain) GKSession *currentSession;
@property (nonatomic, retain) UITextField *txtMessage;
@property (nonatomic, retain) UIButton *connect;
@property (nonatomic, retain) UIButton *disconnect;
-(IBAction) btnSend:(id) sender;
-(IBAction) btnConnect:(id) sender;
-(IBAction) btnDisconnect:(id) sender;
-(IBAction)chooseImageData:(id)sender;
@end
Ve .m: Eğer alıcı uçta gönderildiği anlamak imkansız hiç bir yolu yok gibi
