Question

我有这段代码和错误的文字：

错误：错误域= NSCocoaErrorDomain代码= 4＆＃34;操作无法完成。（可可错误4。）＆＃34; UserInfo = 0x145b5a60 {NSSourceFilePathErrorKey = / private / var / mobile / Containers / Data / Application / E905FE5A-C39B-41F0-8BC7-FC58CC3F4306 / Library / Caches / 2D0404EE-746C-4C1E-98F3-42FFE485BE3B.zip，NSUserStringVariant =（移动），NSFilePath = / private / var / mobile / Containers / Data / Application / E905FE5A-C39B-41F0-8BC7-FC58CC3F4306 / Library / Caches / 2D0404EE-746C-4C1E-98F3-42FFE485BE3B.zip，NSDestinationFilePath = / var / mobile /容器/数据/应用程序/ E905FE5A-C39B-41F0-8BC7-FC58CC3F4306 / Documents / Files / temp.zip，NSUnderlyingError = 0x1457af70＆＃34;操作无法完成。没有这样的文件或目录＆＃34;}

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);
    }
}

真的不明白为什么会发生这种情况

Answer 1

添加错误检查：

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

IOS：将文件移动到目录
