단추를 누를 때 IBAction 메서드가 호출되지 않습니다. 그러나보기 컨트롤러가 푸시되고 있습니다.

Question

*line이라는 IBAction 버튼이있는 segue 푸시 버튼을 사용하여 viewController의 정보를 다른 하나의 정보로 전달하려고합니다. 그러나이 방법은 NSLog (@ "% @"참조)가 호출되지 않고 있음을 알 수 있습니다. 메서드를 테스트하기 위해 삽입 한 메시지가 표시되지 않습니다. 첫 번째 코드는 viewController입니다.

DetailController.m 나는 IBAction 방법에 NSLog(@"%@", see);를 삽입 테스트로

#import "DetailController.h" 
#import "City.h" 
#import "ViewController.h" 

#import "VideoController.h" 
#import "Helper.h"

하지만이 값

DetailController.h

#import "VideoController.h" 
#import <Social/Social.h>

@interface DetailController : UIViewController { 
    IBOutlet UIScrollView *scroller; 
} 

@property (weak, nonatomic) IBOutlet UIBarButtonItem *taxi; 

@property (strong,nonatomic) City *city; 
@property (weak, nonatomic) IBOutlet UILabel *ClubName; 
@property (weak, nonatomic) IBOutlet UILabel *Vip; 
@property (weak, nonatomic) IBOutlet UILabel *Price; 

@property (nonatomic, strong)NSString * camera; 
@property (weak, nonatomic) IBOutlet UILabel *Promo; 
@property (weak, nonatomic) IBOutlet UILabel *remain; 
@property (weak, nonatomic) IBOutlet UILabel *p; 
@property (weak, nonatomic) IBOutlet UILabel *deal; 
@property (weak, nonatomic) IBOutlet UILabel *money; 
@property (weak, nonatomic) IBOutlet UIBarButtonItem *tweet; 
@property (weak, nonatomic) IBOutlet UIBarButtonItem *post; 

- (IBAction)line:(id)sender; 

@end 

이 방법이 왜에 어떤 제안을 주셔서 감사를 반환하지 않습니다 버튼을 눌렀을 때 호출되지 않는다.

Answer 1

IBAction이 호출되지 않도록하는 유일한 방법은 단추가 적절하게 연결되어 있지 않은 경우입니다. 연결 관리자에서 다시 확인하십시오.
