버튼 누르기에서 탐색 버튼 항목 변경

Question

오른쪽 탐색 모음 버튼을 다른 버튼으로 이름 및 동작으로 변경할 수 있기를 원합니다. 예를 들어

:

btnOpenImage을 누를 때와 rightNavButton1이 시도 rightNavButton2

Answer 1

-(IBAction) btnOpenImage_Clicked:(id)sender{ 

//1. IF buttons are UIBarButtonItem then use bellow code 
        // This bellow line for Change the action(Target) 
       [rightNavButton1 setAction:@selector(rightNavButton2_Clicked)]; 

       //This bellow line For Change the Title 
       [rightNavButton1 setTitle:@"rightNavButton2_Clicked"]; 

//OR 2. IF buttons are UIButton then use bellow code 

       // This bellow line for Change the action(Target) 
       [rightNavButton1 addTarget:self action:@selector(rightNavButton2_Clicked) forControlEvents:UIControlEventTouchUpInside]; 

       //This bellow line For Change the Title 
       [rightNavButton1 setTitle: @"rightNavButton2" forState: UIControlStateNormal]; 
    } 

Answer 2

로 변경 :

[btnOpenImage addTarget:self 
       action:@selector(aMethod) 
    forControlEvents:UIControlEventTouchDown]; 

- (void)aMethod 
{ 
    [rightNavButton1 setTitle: @"rightNavButton2" forState: UIControlStateNormal]; 

}
