어떤 아이디어가 있습니까? 나는 그것을 굴절 시키라고 제안되었다. 그러나 나는 그것에 어떻게 잘 모른다!

Answer 1

배열과 사전을 만드는 것이 좋습니다 : 하나는 모든 파일 경로를 보유하고 다른 하나는 arrayStructures를 유지하는 것입니다.

데이터를로드하려는 모든 파일 이름을 사용하여 filepaths 배열을 만듭니다.

arrayStructures 사전은 처음에는 용량이 25 (알파벳 -1 (x는 사용하지 않음)의 문자) 인 빈 NSMutableDictionary이어야합니다.

filepaths 배열을 반복하고 각 반복 끝에 수행 한 정확한 작업을 수행하십시오. addObject: forKey: arrayStructures 사전을 호출해야합니다.

NSMutableDictionary *structures = [ [ NSMutableDictionary alloc ] initWithCapacity:25 ]; 
NSArray *filePaths = [ [NSArray alloc] initWithObjects: @"A", @"B", @"C", @"D", @"E", @"F", @"G", @"H", @"I", @"J", @"K", @"L", @"M", @"N", @"O", @"P", @"Q", @"R", @"S", @"T", @"U", @"V", @"W", /* no X */@"Y", @"Z" ]; // you could also just create a standalone text file and load it from there, i know this is ridiculous! 

for(NSString *path in filePaths) { 
    NSString *filePath = [[NSBundle mainBundle] pathForResource:path ofType:@"txt"]; 
    NSString *myText = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil]; 
    [ structures addObject: [myText componentsSeparatedByString:@"-"] forKey: path ]; 
} 

사전을 통해

이제 루프 ....

for(NSString *filePath in structures) { 
    NSArray *structure = [ structure objectForKey: filePath ]; 
    //... 
}

당신은 정말이 매크로를 사용할 수있는 완벽한 기회처럼 보이는 생각하는 모든 로컬 변수를 원하는 경우 (내가 말할 감히 경우)

#define MAKEARRAY(_letter) \ 
    NSString *filePath ## _letter = [[NSBundle mainBundle] pathForResource:@ #_letter ofType:@"txt"]; \ 
    NSString *myText ## _letter = [NSString stringWithContentsOfFile:filePath ## _letter encoding:NSUTF8StringEncoding error:nil]; \ 
    NSArray *arrayStructures ## _letter = [myText ## _letter componentsSeparatedByString:@"-"] 

MAKEARRAY(A); 
MAKEARRAY(B); 
MAKEARRAY(C); 
: 
: 
MAKEARRAY(W); 
//MAKEARRAY(X); none with X 
MAKEARRAY(Y); 
MAKEARRAY(Z); 

Answer 3

냄새는 루프를 작성할 수있는 좋은 기회입니다.

당신은 당신의 코드가 반복되는 것을 볼 수 있습니다, 그래서 당신이해야 할 무엇을, 로 루프 각 요소에서 유사한 구성 요소를 추출 입력 또는 출력 배열로 다른 compoenent를 추출하고있다 완료되었습니다.
