ios6 - How to set iCloud Root in iPhone? -

here created local root document storage want implement icloud.so need create icloud root , check if icloud available or not. if possible create method. here added local root method code

- (nsurl *)localroot { if (_localroot != nil) { homecoming _localroot; } nsarray *paths = nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes); nsstring *documentsdirectory = [paths objectatindex:0]; nsstring *artdirectorypath = [documentsdirectory stringbyappendingpathcomponent:@"/me"]; _localroot=[[nsurl alloc]initfileurlwithpath:artdirectorypath]; homecoming _localroot; }

you find icloud "root" directory using:

nsurl *url = [[nsfilemanager defaultmanager] urlforubiquitycontaineridentifier:nil];

if have 1 ubiquity container app, can pass nil argument, otherwise must pass container identifier.

you can utilize check if icloud available app-- if returns nil, can't utilize icloud. it's not best way check availability though, because can block while. quick, non-blocking check, utilize this:

id token = [[nsfilemanager defaultmanager] ubiquityidentitytoken];

and sure observe nsubiquityidentitydidchangenotification in case availability changes.

however: near plenty start using icloud documents. can't read/write files in directory , have icloud right thing. @ absolute minimum you'll need:

nsmetadataquery find documents exist on cloud server not downloaded locally. -[nsfilemanager startdownloadingubiquitousitematurl:error:] tell icloud begin downloading documents you've found metadata query. coordinated access via nsfilecoordinator, , notifications of changes via nsfilepresenter.

apple has lot of documentation, , videos wwdc help this.
