C4 카메라 캡처 -보기로 돌아갈 때의 문제

Question

여러 하위 뷰가있는 앱에서 작업하고 있습니다.

현재 4 개의 하위보기가 있습니다. 여기 그것은 C4Workspace 코드 (이 메인 작업은 또한 뷰

-(void)goToTakePhoto{ 
    [takePhoto resetCounter]; 
    [takePhoto setup]; 

    C4Log(@"TakePhoto"); 
    takePhoto.canvas.hidden=NO; 
    cropPhoto.canvas.hidden=YES; 
    assignLetter.canvas.hidden=YES; 
    alphabetView.canvas.hidden=YES; 
} 
-(void)goToCropPhoto{ 
    C4Log(@"going to CropPhoto"); 
    [cropPhoto displayImage:takePhoto.img]; 
    [cropPhoto setup]; 
    takePhoto.canvas.hidden=YES; 
    cropPhoto.canvas.hidden=NO; 
    assignLetter.canvas.hidden=YES; 
    alphabetView.canvas.hidden=YES; 
} 
-(void)goToAssignPhoto{ 
    C4Log(@"AssignPhoto"); 
    [assignLetter setup]; 
    [assignLetter drawCurrentAlphabet:currentAlphabet]; 
    [assignLetter drawCroppedPhoto:cropPhoto.croppedPhoto]; 
    takePhoto.canvas.hidden=YES; 
    cropPhoto.canvas.hidden=YES; 
    assignLetter.canvas.hidden=NO; 
    alphabetView.canvas.hidden=YES; 
} 
-(void)goToAlphabetsView{ 
    C4Log(@"AlphabetsView"); 
    [alphabetView setup]; 
    [alphabetView drawCurrentAlphabet:assignLetter.currentAlphabet]; 
    takePhoto.canvas.hidden=YES; 
    cropPhoto.canvas.hidden=YES; 
    assignLetter.canvas.hidden=YES; 
    alphabetView.canvas.hidden=NO; 
} 

제보기 튜토리얼 매우 유사 사진 촬영 간의 전환은 다음과 같은 기능을 갖는다

//TakePhoto 
    takePhoto= [TakePhoto new]; 
    takePhoto.canvas.frame=CGRectMake(0, 0, self.canvas.width, self.canvas.height); 
    takePhoto.canvas.userInteractionEnabled = YES; 
    [takePhoto transferVariables:1 topBarFromTop:TopBarFromTopDefault topBarHeight:TopNavBarHeightDefault bottomBarHeight:BottomBarHeightDefault navBarColor:navBarColorDefault navigationColor:navigationColorDefault typeColor:typeColorDefault fatFont:fatFontDefault normalFont:normalFontDefault iconTakePhoto:iconTakePhoto iconClose:iconClose iconBack:iconBack]; 
    [takePhoto setup]; 
    [takePhoto cameraSetup]; 
    [self.canvas addSubview:takePhoto.canvas]; 

    //CropPhoto 
    cropPhoto=[CropPhoto new]; 
    cropPhoto.canvas.frame=CGRectMake(0, 0, self.canvas.width, self.canvas.height); 
    cropPhoto.canvas.userInteractionEnabled=YES; 
    [cropPhoto transferVariables:1 topBarFroTop:TopBarFromTopDefault topBarHeight:TopNavBarHeightDefault bottomBarHeight:BottomBarHeightDefault navBarColor:navBarColorDefault navigationColor:navigationColorDefault typeColor:typeColorDefault overlayColor:overlayColorDefault fatFont:fatFontDefault normalFont:normalFontDefault iconClose:iconClose iconBack:iconBack iconOk:iconOk]; 
    [self.canvas addSubview:cropPhoto.canvas]; 
    cropPhoto.canvas.hidden= YES; 

    //AssignPhoto 
    assignLetter=[AssignLetter new]; 
    assignLetter.canvas.frame=CGRectMake(0, 0, self.canvas.width, self.canvas.height); 
    assignLetter.canvas.userInteractionEnabled=YES; 
    [assignLetter transferVariables:1 topBarFroTop:TopBarFromTopDefault topBarHeight:TopNavBarHeightDefault bottomBarHeight:BottomBarHeightDefault navBarColor:navBarColorDefault navigationColor:navigationColorDefault typeColor:typeColorDefault highlightColor:highlightColorDefault fatFont:fatFontDefault normalFont:normalFontDefault iconClose:iconClose iconBack:iconBack iconOk:iconOk iconSettings:iconSettings]; 

    [self.canvas addSubview:assignLetter.canvas ]; 
    assignLetter.canvas.hidden=YES; 

    //AlphabetView 
    alphabetView=[AlphabetView new]; 
    alphabetView.canvas.frame= CGRectMake(0, 0, self.canvas.width, self.canvas.height); 
    alphabetView.canvas.userInteractionEnabled=YES; 
    [alphabetView transferVaribles:1 topBarFromTop:TopBarFromTopDefault topBarHeight:TopNavBarHeightDefault bottomBarHeight:BottomBarHeightDefault navBarColor:navBarColorDefault navigationColor:navigationColorDefault typeColor:typeColorDefault darkenColor:darkenColorDefault fatFont:fatFontDefault normalFont:normalFontDefault iconClose:iconClose iconBack:iconBack iconMenu:iconMenu iconTakePhoto:iconTakePhoto iconAlphabetInfo:iconAlphabetInfo iconShareAlphabet:iconShareAlphabet iconWritePostcard:iconWritePostcard iconMyPostcards:iconMyPostcards iconMyAlphabets:iconMyAlphabets]; 
    [self.canvas addSubview:alphabetView.canvas]; 
    alphabetView.canvas.hidden=YES; 

//the methods to listen for from all other canvasses 
    [self listenFor:@"goToTakePhoto" andRunMethod:@"goToTakePhoto"]; 
    [self listenFor:@"goToCropPhoto" andRunMethod:@"goToCropPhoto"]; 
    [self listenFor:@"goToAssignPhoto" andRunMethod:@"goToAssignPhoto"]; 
    [self listenFor:@"goToAlphabetsView" andRunMethod:@"goToAlphabetsView"]; 

들을 설정하는 방법 사진을 찍을 버튼이 탭되었을 때 항상 두 번 알림을 보냈 음을 알았 기 때문에 카메라의 재설정 카운터를 추가했습니다. 난 다시 이미지에서 이동하고있어 만약 내가 다시 C4Label에서 해당보기로하지만 탐색 할

-(void) setup{ 
photoButtonImage=iconTakePhoto; 
    photoButtonImage.height=45; 
    photoButtonImage.width=90; 
    photoButtonImage.center=CGPointMake(self.canvas.width/2, self.canvas.height-bottomBarHeight/2); 
    [self.canvas addImage:photoButtonImage]; 
    //gestures to take the photo 
    [self listenFor:@"touchesBegan" fromObject:photoButtonImage andRunMethod:@"captureImage"]; 
    [self numberOfTouchesRequired:1 forGesture:@"capture"]; 
    [self listenFor:@"imageWasCaptured" fromObject:cam andRunMethod:@"goToCropPhoto"]; 
} 

-(void)cameraSetup{ 
    cam = [C4Camera cameraWithFrame:CGRectMake(0,topBarFromTop+topBarHeight, self.canvas.width, self.canvas.height-(topBarHeight+bottomBarHeight+topBarFromTop))]; 
    cam.cameraPosition = CAMERABACK; 
    [self.canvas addCamera:cam]; 
    [cam initCapture]; 
    counter=0; 
} 
-(void) captureImage{ 
    [cam captureImage]; 
    C4Log(@"capturing image"); 
} 
-(void)resetCounter{ 
    counter=0; 
} 

이만큼 잘 작동합니다. 비록 두 함수를 만질 때 똑같은 함수를 실행하고 있습니다.

//image as navigation element 
takePhotoButton=iconTakePhoto; 
    takePhotoButton.width=60; 
    takePhotoButton.center=CGPointMake(takePhotoButton.width/2+5, bottomNavBar.center.y); 
    [self.canvas addImage:takePhotoButton]; 
    [self listenFor:@"touchesBegan" fromObject:takePhotoButton andRunMethod:@"goToTakePhoto"]; 

//label as navigation element 
takePhoto=[C4Label labelWithText:@"take Photo" font: normalFont]; 
    takePhoto.center=CGPointMake(self.canvas.width-(takePhoto.width/2+5), topNavBar.center.y); 
    [self.canvas addLabel:takePhoto ]; 
    [self listenFor:@"touchesBegan" fromObject:takePhoto andRunMethod:@"goToTakePhoto"]; 

을 그리고 마지막으로이 내가 지금 라벨을 사용하여 작동 할 수 있지만 너무 좋을 것 테 알림을

-(void) goToTakePhoto{ 
    C4Log(@"goToTakePhoto"); 
    [self removeFromView]; //removes the currently displayed items from being displayed 
    [self postNotification:@"goToTakePhoto"]; 
} 

을 보내는 내부보기 기능입니다 : 은 다음과 같습니다 C4Image를 버튼으로 사용하려면 .... 아이디어가 있으십니까? Github에서에 전체 코드를 사용할 수 : http://github.com/susemiessner/Urban-Alphabets/tree/master/urbanAlphabetsII

Answer 1

난 그냥 이것에 대한 답변을 발견 : 카메라에 돌아 오는 때 이미 이미지를 캡처 한 생각 때문에 가 이전

[self listenFor:@"imageWasCaptured" fromObject:cam andRunMethod:@"goToCropPhoto"]; 

여전히 활성화 된보기 사실이 아닌 카메라에서. 그래서 해결책을 떠날 때 나는이 코드를 사용하지 않도록 설정해야합니다.

[self stopListeningFor:@"imageWasCaptured" object:cam]; 

전체 마법을 수행합니다!
