Screenshots

How to use

Import #import "APCloudCore.h" in your project.

Next, set your delegate, and your file prefix.
File prefix, is very important if you want to separate files, because iCloud don't permit to create and read folders.

Every classes provides a singleton access.

[[APCloudCore sharedCloud] setDelegate:self];
[[APCloudCore sharedCloud] setFilePrefix:@"ap"];

Methods:

Check for cloud enabled

[[APCloudCore sharedCloud] isCloudEnabled];

Save a file

[[APCloudCore sharedCloud] saveData:yourData withName:yourFileName];

Load a file

[[APCloudCore sharedCloud] loadDataWithName:yourFileName];

Delete a file

[[APCloudCore sharedCloud] deleteFileWithName:yourFileName];

Load all cloud files

[[APCloudCore sharedCloud] loadAllFilesWithPrefix:yourPrefix];

APCloudCoreDelegate

If you're implemented the optionals delegate, you should implements the delegates (finish and fail):

- (void) apCloudCoreDidFinishUpdate;
- (void) apCloudCoreDidFailUpdate;

- (void) apCloudCoreDidFinishLoadFiles:(NSMutableArray*)file;
- (void) apCloudCoreDidFailLoadFiles;

- (void) apCloudCoreDidFinishSaveData:(id)data;
- (void) apCloudCoreDidFailSaveData:(id)data;

- (void) apCloudCoreDidFinishLoadData:(id)data;
- (void) apCloudCoreDidFailLoadData:(id)data;

- (void) apCloudCoreDidFinishDeleteData:(id)data;
- (void) apCloudCoreDidFailDeleteData:(id)data;

Notes on SAVE

Save method, accept an id as file. This id is your custom class, that must implements NSCoding protocol.

Example of test store class:

@interface APTestStore : NSObject <NSCoding>

@property (nonatomic, strong) NSString *aTitle;
@property (nonatomic, strong) NSString *aSubTitle;
@property (nonatomic, strong) NSString *aDescription;

@end

@implementation APTestStore
@end

This class is saved (encrypted) and loaded (decrypted) to/from cloud as NSData.

Cloud files

File are stored in your Cloud directory, that is accessibile from web, at url http://developer.icloud.com or in your Mac local folder, ~/Library/Mobile Documents/.

Files are stored using this tree:

~/Library/Mobile Documents/XXXXXXX~it~albertopasca~dev-app/Documents/

ap_test-file-1.dat
ap_test-file-2.dat
ap_test-file-3.dat
xx-afile-1.dat
xx-afile-2.dat
[...]

"ap" or "xx" are the prefixes of your files!

Have fun.
