CloudKit

CloudKit, Apple’s remote data storage service, provides a possibility to store app data using users’ iCloud accounts as a back-end storage service.

Here is the same demo on Swift.

Requirements

iOS 8.0

How To Get Started

  • Set up Cloud/CloudKit at iOS Developer Portal.
  • Insert a bundle identifier and choose a corresponding Team.
  • Select Capabilities tab in the target editor, and then switch ON the iCloud.

For more detailed information take a look at our article.

Usage

Retrieve existing records

NSPredicate *predicate = [NSPredicate predicateWithValue:YES];
CKQuery *query = [[CKQuery alloc] initWithRecordType:@"RecordType" predicate:predicate];
    
[[CKContainer defaultContainer].publicCloudDatabase performQuery:query
                                                    inZoneWithID:nil
                                                completionHandler:^(NSArray *results, NSError *error) {
                                                  
}];

Create a new record

CKRecord *record = [[CKRecord alloc] initWithRecordType:@"RecordType"];
record[@"key"] = @"Some data";
[[CKContainer defaultContainer].publicCloudDatabase saveRecord:record completionHandler:^(CKRecord *record, NSError *error) {

}];

Update the record

CKRecordID *recordID = [[CKRecordID alloc] initWithRecordName:@"recordId"];
[[CKContainer defaultContainer].publicCloudDatabase fetchRecordWithID:recordID completionHandler:^(CKRecord *record, NSError *error) {
        
  if (error) {
    return;
  }
        
  record[@"key"] = @"Some data";
  [[CKContainer defaultContainer].publicCloudDatabase saveRecord:record completionHandler:^(CKRecord *record, NSError *error) {

  }];
}];

Remove the record

CKRecordID *recordID = [[CKRecordID alloc] initWithRecordName:@"recordId"];
[[CKContainer defaultContainer].publicCloudDatabase deleteRecordWithID:recordID completionHandler:^(CKRecordID *recordID, NSError *error) {

}];
