Question

我想在iCloud上存储.zip文件。有人帮我上传和恢复？我已经阅读了iCloud备份的Apple指南，现在我创建了一个包含一些文件的文件夹和两个包含多个图像的文件夹，然后生成该文件夹的zip文件。

Answer 1

首先在本地存储上保存文件和文件夹。
然后创建此文件＆amp;文件夹的Zip文件。
上次上传您在iCloud上的zip文件。
为了让这个文件进行逆向处理。

- (void)viewDidLoad {
    [super viewDidLoad];

    [self CreatFileAndFolder];

}

在本地创建文件夹，并在此文件夹中保存要在iCloud Drive上上传的文件。

-(void)CreatFileAndFolder{

    NSError *error;
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
    NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"/meetInChat"];

    if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
        [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error];


    NSString *stringToWrite = @"1\n2\n3\n41\n2\n3\n41\n2\n3\n41\n2\n3\n41\n2\n3\n41\n2\n3\n41\n2\n3\n41\n2\n3\n41\n2\n3\n41\n2\n3\n41\n2\n3\n41\n2\n3\n41\n2\n3\n41\n2\n3\n41\n2\n3\n41\n2\n3\n4";


    NSString *exportPath = [dataPath stringByAppendingString:@"/mytext.txt"];
    [stringToWrite writeToFile:exportPath atomically:YES encoding:NSUTF8StringEncoding error:&error];

}

创建首先创建Zip文件的文件夹，然后在iCloud Drive上上传您的Zip文件。

-(IBAction) iCloudSyncing:(id)sender
{
    [self zipFolder];

    //--------------------------Zip Folder Upload on iCloud-----------------------------//

    NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
    NSString *zipFilePath = [documentsDirectory stringByAppendingPathComponent:@"meetInChat.zip"];
    NSLog(@"FilePath=>%@",zipFilePath);
    NSURL *u = [[NSURL alloc] initFileURLWithPath:zipFilePath];
    NSData *data = [[NSData alloc] initWithContentsOfURL:u];

    NSURL *ubiq = [[NSFileManager defaultManager]URLForUbiquityContainerIdentifier:nil];
    NSURL *ubiquitousPackage = [[ubiq URLByAppendingPathComponent:@"Documents"]URLByAppendingPathComponent:@"meetInChat.zip"];
    Mydoc = [[MyDocument alloc] initWithFileURL:ubiquitousPackage];
    Mydoc.zipDataContent = data;

    [Mydoc saveToURL:[Mydoc fileURL] forSaveOperation:UIDocumentSaveForCreating completionHandler:^(BOOL success)
     {
         if (success)
         {
             NSLog(@"PictureZip: Synced with icloud");

             [[NSUbiquitousKeyValueStore defaultStore]setData:data forKey:@"meetInChat"];
         }
         else
             NSLog(@"PictureZip: Syncing FAILED with icloud");

     }];
}

从您的文件夹中创建Zip文件

-(BOOL)zipFolder
{

//--------------------------Create Zip Folder -----------------------------//
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *docDirectory = [paths objectAtIndex:0];
    BOOL isDir=NO;
    NSArray *subpaths = nil;
    NSString *exportPath = [docDirectory stringByAppendingString:@"/meetInChat"];

    NSFileManager *fileManager = [NSFileManager defaultManager];
    if ([fileManager fileExistsAtPath:exportPath isDirectory:&isDir] && isDir){
        subpaths = [fileManager subpathsAtPath:exportPath];
    }

    NSString *meetInChatPath = [docDirectory stringByAppendingString:[NSString stringWithFormat:@"/%@.zip",@"meetInChat"]];

    ZipArchive *archiver = [[ZipArchive alloc] init];
    [archiver CreateZipFile2:meetInChatPath];


    if (isDir) {
        for(NSString *path in subpaths){
            NSString *fullPath = [exportPath stringByAppendingPathComponent:path];
            if([fileManager fileExistsAtPath:fullPath isDirectory:&isDir] && !isDir){
                [archiver addFileToZip:fullPath newname:path];
            }
        }
    } else {
        [archiver addFileToZip:exportPath newname:@"meetInChat"];
    }

    BOOL successCompressing = [archiver CloseZipFile2];
    if(successCompressing)
        return YES;
    else
        return NO;
}

这里从iCloud Drive获取ZipFile然后执行反向过程解压缩文件并获取数据。

- (IBAction)GetData:(id)sender {

    //--------------------------Get data back from iCloud -----------------------------//
    id token = [[NSFileManager defaultManager] ubiquityIdentityToken];
    if (token == nil)
    {
        NSLog(@"ICloud Is not LogIn");
    }
    else
    {
        NSLog(@"ICloud Is LogIn");

        NSData *dataFile = [[NSUbiquitousKeyValueStore defaultStore]dataForKey:@"meetInChat"];

        NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
        NSString* fileName = [NSString stringWithFormat:@"meetInChat.zip"];
        NSString* fileAtPath = [documentsDirectory stringByAppendingPathComponent:fileName];

        [dataFile writeToFile:fileAtPath atomically:NO];

    }      
}
