IBAction in theos에서 정적 void로

Question

나는 동작이있는 단추를 만드는 정적 void가 있습니다. 또한 정적 void가되도록 작업을 원하지만 패키지를 만들려고 할 때 오류가 발생합니다.

코드 :

typedef enum { 
    SBIconLocationHomeScreen = 0, 
    SBIconLocationDock  = 1, 
    SBIconLocationSwithcer = 2 
} SBIconLocation; 

static UIButton *okbtn; 

@interface SBApplicationIcon 
- (void)launchFromLocation:(SBIconLocation)location context:(id)arg2; 
@end 

static void AddBtn() 
{ 
    UIWindow *window = [[UIApplication sharedApplication] keyWindow]; 

    okbtn = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [okbtn addTarget:window action:@selector(checkpw:) forControlEvents:UIControlEventTouchUpInside]; 
    [okbtn setTitle:@"Done" forState:UIControlStateNormal]; 
    [okbtn setTitleColor:[UIColor greenColor] forState:UIControlStateNormal]; 
    okbtn.frame = CGRectMake(0, 0, 160, 40); 
    okbtn.translatesAutoresizingMaskIntoConstraints = NO; 
    [UIView transitionWithView:window duration:0.4 options:UIViewAnimationOptionTransitionCrossDissolve animations:^{ 
     [window addSubview:okbtn]; 
    } completion:nil]; 
    [window addConstraints:[NSLayoutConstraint 
          constraintsWithVisualFormat:@"V:|-255-[okbtn(40)]" 
          options:NSLayoutFormatDirectionLeadingToTrailing 
          metrics:nil 
          views:NSDictionaryOfVariableBindings(okbtn)]]; 
    [window addConstraints:[NSLayoutConstraint 
          constraintsWithVisualFormat:@"H:[okbtn(160)]" 
          options:0 
          metrics:nil 
          views:NSDictionaryOfVariableBindings(okbtn)]]; 
    [window addConstraint:[NSLayoutConstraint 
          constraintWithItem:okbtn attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:window attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0.0]]; 
} 

static void checkpw() 
{ 
    //Something 
} 

%hook SBApplicationIcon 
- (void)launchFromLocation:(SBIconLocation)location context:(id)arg2 
{ 
    AddBtn(); 
} 
%end 

오류 :

Tweak.xm:43:13: error: unused function 'checkpw' [-Werror,-Wunused-function] 
static void checkpw() 

내가 그것을 어떻게 해결할 수 있습니까?

문제는 코드의 두 섹션이 있습니다 : 당신은 선택기로 일반 오래된 C 방법을 사용하고

[okbtn addTarget:window action:@selector(checkpw:) forControlEvents:UIControlEventTouchUpInside]; 

// … 

static void checkpw() 
{ 
    //Something 
} 

. 선택자는 Objective-C 메소드에서만 작동합니다. 당신은 Objective-C 클래스를 생성하고 거기에 메소드를 추가해야합니다 :
