[Unity3D/iOS] Unity3D에서 iOS기반 사진 캡쳐 및 카메라 엘범 사용

Unity - iOS 접근 플러그인 방법

 

제목 : Unity for IOS_Screen Capture한 이미지 카메라롤 에 등록하기.

 

Explan.

IOS에서 Application.CaptureScreenShot(path) 메소드를 사용할경우
캡처는 진행되나 해당 app 의 document폴더로 들어가서 카메라 롤에서 확인할수가 없다.
이를 등록해주는 방법 포스팅.


CaptureHelper.h

#import <Foundation/Foundation.h>

@interface CaptureHelper : NSObject

+(CaptureHelper *)sharedInstancs;

@end

CaptureHelper.mm

#import "CaptureHelper.h"

static CaptureHelper * captureHelper = [CaptureHelper sharedInstancs];

@implementation CaptureHelper : NSObject

+ (void)initialize{
    if(captureHelper == nil)
        captureHelper = [[CaptureHelper alloc] init];
}

+ (CaptureHelper *)sharedInstancs{
    return captureHelper;
}

- (id)init{
    if(captureHelper != nil){
        return  captureHelper;
    }
    
    self = [super init];
    if(self){
        captureHelper = self;
    }
    
    return self;
}


- (NSString *)getDocumentDirectory {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    
    return [paths objectAtIndex:0];
}

@end

extern "C"{
    void CaptureToCameraRoll(const char *fileName)
    {
        NSString *file = [NSString stringWithUTF8String:(fileName)];
        NSString *filePath = [[captureHelper getDocumentDirectory] stringByAppendingString:file];
        UIImage *image = [[UIImage alloc] initWithContentsOfFile:filePath];
        
        UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);
    }
}

위 2개의 파일을 생성후 Plugin/IOS 폴더에 위치 그후

how to used.

[DllImport("__Internal")]
public static extern void CaptureToCameraRoll(String fileName);

// 그이후 스크린 캡처 진행시.

Application.CaptureScreenShot(path);
CaptureToCameraRoll(string.Format("/{0}",path));

이후 카메라롤에서 캡쳐된 이미지를 확인하실수 있다.
