특정 디렉토리에 사진 저장

Question

디렉토리에 사진을 저장하고 싶습니다. 그러나 뷰 컨트롤러에서이 코드를 사용하여 모자 바닥이라고하는 디렉토리를 오른쪽 및 왼쪽으로 만들었습니다.

NSArray *directoryNames = [NSArray arrayWithObjects:@"hats",@"bottoms",@"right",@"left",nil]; 
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder 

    for (int i = 0; i < [directoryNames count] ; i++) { 
     NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:[directoryNames objectAtIndex:i]]; 
     if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath]) 
      [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil]; //Create folder 

UIImage는 사용자가 카메라에서 촬영 한 내용을 앱에 표시합니다. UIIMage.Below에 표시 될 때 내가 만든 디렉토리 (예 : 모자) 중 하나에 자동으로 사진을 저장하고 싶습니다. 사진을 찍은 후 UIImage에 표시하는 코드입니다. 자동으로 디렉토리 중 하나에 저장 하시겠습니까 ?? 특정 디렉토리에 저장하는 장소를 수행 할 수 없습니다.

Answer 1

자동으로 당신이해야하는 경우 명시 적으로 사용자에게 묻지 않고 절약 절약 UPDATE. 이미지를 저장하는 과정은 동일하다 :

1. 는

---

( writeToFile:atomically: 사용) ( UIImageJpegRepresentation 또는 UIImagePngRepresentation 사용) 데이터

저장 데이터로 변환 UIImage

의 인스턴스를 가져옵니다

다음과 같음 :

folderPath = [documentsDirectory stringByAppendingPathComponent:directoryNames[0]]; 

,

또는

folderPath = [documentsDirectory stringByAppendingPathComponent:@"hats"];
