IOS: Перемещение файлов в каталог

Question

У меня есть этот код и сообщение об ошибке с текстом:

ERROR: Error Domain=NSCocoaErrorDomain Code=4 "The operation couldn’t be completed. (Cocoa error 4.)" UserInfo=0x145b5a60 {NSSourceFilePathErrorKey=/private/var/mobile/Containers/Data/Application/E905FE5A-C39B-41F0-8BC7-FC58CC3F4306/Library/Caches/2D0404EE-746C-4C1E-98F3-42FFE485BE3B.zip, NSUserStringVariant=( Move ), NSFilePath=/private/var/mobile/Containers/Data/Application/E905FE5A-C39B-41F0-8BC7-FC58CC3F4306/Library/Caches/2D0404EE-746C-4C1E-98F3-42FFE485BE3B.zip, NSDestinationFilePath=/var/mobile/Containers/Data/Application/E905FE5A-C39B-41F0-8BC7-FC58CC3F4306/Documents/Files/temp.zip, NSUnderlyingError=0x1457af70 "The operation couldn’t be completed. No such file or directory"}

NSFileManager *fileManager = [NSFileManager defaultManager]; 
NSArray *pathDocumentDirectory = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *dictionaryName = @"Files"; 
NSString *filesPath = [[pathDocumentDirectory objectAtIndex:0] stringByAppendingPathComponent:dictionaryName]; 
NSString *toPath = [filesPath stringByAppendingPathComponent:@"temp.zip"]; 
NSString *fromPath = downloadedItem.contentURL.path; 
NSError *error = nil; 
BOOL isDir = YES; 

if([fileManager fileExistsAtPath:fromPath]) 
{ 
    // Create PurchasedBooks directory 
    if (![fileManager fileExistsAtPath:dictionaryName isDirectory:&isDir]) { 
     [fileManager createDirectoryAtPath:dictionaryName withIntermediateDirectories:NO attributes:nil error:&error]; 
    } 
    [[NSFileManager defaultManager]moveItemAtPath:fromPath toPath:toPath error:&error]; 

    if (error) { 
     NSLog(@"ERROR: %@", error.description); 
    } 
} 

На самом деле не понимаю, почему это происходит

Answer 1

Добавить ошибку проверки:

[fileManager createDirectoryAtPath:dictionaryName withIntermediateDirectories:NO attributes:nil error:&error];
