Так я синхронизировал zip-файлы с iCloud.
Шаги:
1) http://transoceanic.blogspot.in/2011/07/compressuncompress-files-on.html
, Перейдите по этой ссылке, чтобы скачать zip api с кодом для архивирования и распаковки папки.
2) Теперь все, что вам нужно для игры с NSData.
3) Файл "MyDocument.h"
#import <UIKit/UIKit.h>
@interface MyDocument : UIDocument
@property (strong) NSData *zipDataContent;
@end
4)
#import "MyDocument.h"
@implementation MyDocument
@synthesize zipDataContent;
// Called whenever the application reads data from the file system
- (BOOL)loadFromContents:(id)contents ofType:(NSString *)typeName error:(NSError **)outError
{
self.zipDataContent = [[NSData alloc] initWithBytes:[contents bytes] length:[contents length]];
[[NSNotificationCenter defaultCenter] postNotificationName:@"noteModified" object:self];
return YES;
}
// Called whenever the application (auto)saves the content of a note
- (id)contentsForType:(NSString *)typeName error:(NSError **)outError
{
return self.zipDataContent;
}
@end
5) Теперь где-то в вашем приложении вам нужно сжать папку и синхронизировать с icloud.
-(BOOL)zipFolder:(NSString *)toCompress zipFilePath:(NSString *)zipFilePath
{
BOOL isDir=NO;
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *pathToCompress = [documentsDirectory stringByAppendingPathComponent:toCompress];
NSArray *subpaths;
NSFileManager *fileManager = [NSFileManager defaultManager];
if ([fileManager fileExistsAtPath:pathToCompress isDirectory:&isDir] && isDir){
subpaths = [fileManager subpathsAtPath:pathToCompress];
} else if ([fileManager fileExistsAtPath:pathToCompress]) {
subpaths = [NSArray arrayWithObject:pathToCompress];
}
zipFilePath = [documentsDirectory stringByAppendingPathComponent:zipFilePath];
//NSLog(@"%@",zipFilePath);
ZipArchive *za = [[ZipArchive alloc] init];
[za CreateZipFile2:zipFilePath];
if (isDir) {
for(NSString *path in subpaths){
NSString *fullPath = [pathToCompress stringByAppendingPathComponent:path];
if([fileManager fileExistsAtPath:fullPath isDirectory:&isDir] && !isDir){
[za addFileToZip:fullPath newname:path];
}
}
} else {
[za addFileToZip:pathToCompress newname:toCompress];
}
BOOL successCompressing = [za CloseZipFile2];
if(successCompressing)
return YES;
else
return NO;
}
-(IBAction) iCloudSyncing:(id)sender
{
//***** PARSE ZIP FILE : Pictures *****
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
if([self zipFolder:@"Pictures" zipFilePath:@"iCloudPictures"])
NSLog(@"Picture Folder is zipped");
ubiq = [[NSFileManager defaultManager]URLForUbiquityContainerIdentifier:nil];
ubiquitousPackage = [[ubiq URLByAppendingPathComponent:@"Documents"] URLByAppendingPathComponent:@"iCloudPictures.zip"];
mydoc = [[MyDocument alloc] initWithFileURL:ubiquitousPackage];
NSString *zipFilePath = [documentsDirectory stringByAppendingPathComponent:@"iCloudPictures"];
NSURL *u = [[NSURL alloc] initFileURLWithPath:zipFilePath];
NSData *data = [[NSData alloc] initWithContentsOfURL:u];
// NSLog(@"%@ %@",zipFilePath,data);
mydoc.zipDataContent = data;
[mydoc saveToURL:[mydoc fileURL] forSaveOperation:UIDocumentSaveForCreating completionHandler:^(BOOL success)
{
if (success)
{
NSLog(@"PictureZip: Synced with icloud");
}
else
NSLog(@"PictureZip: Syncing FAILED with icloud");
}];
}
6) Вы можете разархивировать данные, полученные из iCloud, следующим образом.
- (void)loadData:(NSMetadataQuery *)queryData {
for (NSMetadataItem *item in [queryData results])
{
NSString *filename = [item valueForAttribute:NSMetadataItemDisplayNameKey];
NSURL *url = [item valueForAttribute:NSMetadataItemURLKey];
MyDocument *doc = [[MyDocument alloc] initWithFileURL:url];
if([filename isEqualToString:@"iCloudPictures"])
{
[doc openWithCompletionHandler:^(BOOL success) {
if (success) {
NSLog(@"Pictures : Success to open from iCloud");
NSData *file = [NSData dataWithContentsOfURL:url];
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *zipFolder = [documentsDirectory stringByAppendingPathComponent:@"Pics.zip"];
[[NSFileManager defaultManager] createFileAtPath:zipFolder contents:file attributes:nil];
//NSLog(@"zipFilePath : %@",zipFolder);
NSString *outputFolder = [documentsDirectory stringByAppendingPathComponent:@"Pictures"];//iCloudPics
ZipArchive* za = [[ZipArchive alloc] init];
if( [za UnzipOpenFile: zipFolder] ) {
if( [za UnzipFileTo:outputFolder overWrite:YES] != NO ) {
NSLog(@"Pics : unzip successfully");
}
[za UnzipCloseFile];
}
[za release];
NSError *err;
NSArray *files = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:outputFolder error:&err];
if (files == nil) {
NSLog(@"EMPTY Folder: %@",outputFolder);
}
// Add all sbzs to a list
for (NSString *file in files) {
//if ([file.pathExtension compare:@".jpeg" options:NSCaseInsensitiveSearch] == NSOrderedSame) {
NSLog(@" Pictures %@",file);
// NSFileManager *fm = [NSFileManager defaultManager];
// NSDictionary *attributes = [fm fileAttributesAtPath:[NSString stringWithFormat:@"%@/%@",documentsDirectory,file] traverseLink:NO];
//
// NSNumber* fileSize = [attributes objectForKey:NSFileSize];
// int e = [fileSize intValue]; //Size in bytes
// NSLog(@"%@__%d",file,e);
}
}
else
{
NSLog(@"Pictures : failed to open from iCloud");
[self hideProcessingView];
}
}];
}
}
