KONTROL'e basıyorum ve AppView.xib'deki UIImageVIew ve UILabel'ı "AppVIew.h" adlı kod dosyama sürükliyorum. İki UI widget'ını bağlamadan önce, koştuğumun nedenini bilmek istiyorum. Yanıtlarınız için teşekkürler. Aşağıdaki şekildeUIVIew'i koduma bağladıktan sonra, neden çöktü?
#import <UIKit/UIKit.h>
@interface AppView : UIView
@property (weak, nonatomic) IBOutlet UIImageView *icon;
@property (weak, nonatomic) IBOutlet UILabel *name;
+ (id)AppViewWithIcon:(NSString *)icon Name:(NSString *)name;
@end
#import "AppView.h"
@implementation AppView
+ (id)AppViewWithIcon:(NSString *)icon Name:(NSString *)name{
AppView *view = [[NSBundle mainBundle] loadNibNamed:@"AppView" owner:nil options:nil][0];
NSLog(@"%@",view);
return view;
}
hatalar: kodu aşağıdaki şekilde @property
