ObjectiveCloudant 0.2.3

Maintained by Mike Rhodes, Rhys Short, Tom Blench.

You want to add pod 'ObjectiveCloudant', '~> 0.2' similar to the following to your Podfile:

target 'MyApp' do
  pod 'ObjectiveCloudant', '~> 0.2'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try ObjectiveCloudant

ObjectiveCloudant 0.2.3

By
IBM Cloudant

This library is deprecated, it is recommended you look at SwiftCloudant.

objective-cloudant

This library has been deprecated, it has been replaced with SwiftCloudant

Applications use objective-cloudant to store, index and query remote JSON data on Cloudant or CouchDB.

Objective-Cloudant is an Apache CouchDB™ client. It is built by Cloudant and is available under the Apache 2.0 license.

Early-Release

This is an early-release version of the library, with support for the following operations:

Getting documents by doc ID.
Updating and deleting documents.
Creating Cloudant Query indexes (both JSON and text indexes).
Finding documents via Cloudant Query.

We will be rounding out the feature set in upcoming releases.

Using in your project

objective-cloudant is available through CocoaPods, to install it add the following line to your Podfile:

pod ObjectiveCloudant

Overview of the library

Once the library is added to a project the basics of adding and reading a document are:

#import <ObjectiveCloudant/ObjectiveCloudant.h>

//Create a CDTCouchDBClient
NSURL *cloudantURL = [NSURL URLWithString:@"https://username.cloudant.com"];
CDTCouchDBClient *client = [CDTCouchDBClient clientForUrl:cloudantURL
                                                 username:@"username"
                                                 password:@"password"];

//access database
CDTDatabase *db = client[@"databasename"];

//create a document
[db putDocumentWithId:@"doc1"
                 body:@{@"hello":@"world"}
     completionHander:^(NSString *docId,
                        NSString *revId,
                        NSInteger statusCode,
                        NSError *operationError){
        if (operationError){
            NSLog(@"Error encountered while creating a document. Error: %@", error);
        } else {
            NSLog(@"Created document %@ with revision id %@", docId, revId);
        }

}];

//read a document
[db getDocumentWithId:@"doc1"
     completionHander:^(NSDictionary<NString*,NSObject*> *document,
                       NSError *operationError){
        if (operationError) {
            NSLog(@"Encountered an error while reading a document. Error:%@", error);
        } else {
            NSLog(@"Read document: %@",document);
        }
}];

//delete a document
[db deleteDocumentWithId:@"doc1"
           revisionId: @"1-revisionidhere"
    completionHandler: ^(NSInteger statusCode, error){
        if (error) {
            NSLog(@"Encountered an error while deleting a document. Error: %@", error);
        } else {
            NSLog(@"Document deleted");
        }
}];

And in swift use is as follows:

import ObjectiveCloudant

// create a CDTCouchDBClient
let url = NSURL(string: "https://example.cloudant.com")!
let client = CDTCouchDBClient(forURL: url,
        username: "username",
        password: "password")!

//access database
let db = client["example"]!


// create document
db.putDocumentWithId("doc1",
    body: ["hello": "world"],
    completionHandler: { (docId, revId, statusCode, operationError) -> Void in
        if let error = operationError {
            print("Encountered an error creating document. Error: \(error)")
        } else {
            print("Created document \(docId), at revision \(revId)")
        }
})


//read document
db.getDocumentWithId("doc1",
    completionHander:(document, operationError) -> Void {
        if let error = operationError {
            println("Encountered an error reading a document. Error: \(error)")
        } else {
            println("Read document \(document!)")
        }
})

//delete document
db.deleteDocumentWithId("doc1",
    revisionId: "1-revisionidhere",
    completionHandler: { (statusCode, operationError) -> Void in
        if let error = operationError {
            print("Encountered error: \(error!)")
        } else {
            print("document deleted")
        }
})

Finding Data

Objective-cloudant directly supports the Cloudant Query API .

Create Indexes

// Create a JSON Index
CDTCreateQueryIndexOperation *op = [[CDTCreateQueryIndexOperation alloc] init];
op.indexType = CDTQueryIndexTypeJson;
op.fields = @[ @{@"foo":@"asc"}, @{@"bar" : @"desc"}]
op.createIndexCompletionBlock = ^(NSError * _Nullable error){
       if(error){
           NSLog(@"Index creation failed. Error %@",error);
       } else {
           NSLog(@"Index created");
       }
   };

[db addOperation:op];


// Create a text index
CDTCreateQueryIndexOperation *op = [[CDTCreateQueryIndexOperation alloc] init];
op.indexType = CDTQueryIndexTypeText;
op.fields = @[ @{ @"name" : @"foo", @"type" : @"string"}]
op.createIndexCompletionBlock = ^(NSError * _Nullable error){
       if(error){
           NSLog(@"Index creation failed. Error %@",error);
       } else {
           NSLog(@"Index created");
       }
   };

[db addOperation:op];

// Create a JSON index
let op = CDTCreateQueryIndexOperation()
op.indexType = .Json
op.fields = [["foo":"asc"],["bar":desc]]
op.createIndexCompletionBlock =  {(error) -> Void in
        if let _ = error {
            print("Index creation failed with error: \(error)")
        } else {
            print("Index created")
        }
}

db.addOperation(op)

// Create a text index
let op = CDTCreateQueryIndexOperation()
op.indexType = .Text
op.fields = [["name":"foo","type":"string"]]
op.createIndexCompletionBlock =  {(error) -> Void in
        if let _ = error {
            print("Index creation failed with error: \(error)")
        } else {
            print("Index created")
        }
}

db.addOperation(op)

Query for documents

CDTQueryFindDocumentsOperation *op = [[CDTQueryFindDocumentsOperation alloc] init];
op.selector = @{@"foo": @"bar"};
op.documentFoundBlock = ^(NSDictionary * _Nonnull document){
    NSLog(@"Found document %@",document);
};
op.findDocumentCompletionBlock = ^(NSString * _Nullable bookmark, NSError* _Nullable error){
    if(error){
        NSLog(@"Failed to query database for documents");
    } else {
        NSLog(@"Query completed");
    }
};

[db addOperation:op];

let op = CDTQueryFindDocumentsOperation()
op.selector = ["foo":"bar"]
op.documentFoundBlock = {(document) -> Void in
    print("Found document \(document)")
}
op.findDocumentCompletionBlock = {(bookmark, error) -> Void in
    if let _ = error {
        print("Failed to query database for documents")
    } else {
        print("Query completed")
    }
}

db.addOperation(op)

Deleting an index

// Delete a JSON index
CDTDeleteQueryIndex *op = [[CDTDeleteQueryIndex alloc] init];
op.indexType = CDTQueryIndexTypeJson;
op.indexName = @"example";
op.desginDocName = @"exampleDesignDoc";
op.deleteIndexCompletionBlock = ^(NSInteger status, NSError * _Nullable error){
    if (error) {
        NSLog(@"Failed to delete index");
    } else {
        NSLog(@"Index deleted");
    }
};

[db addOperation:op];

// Delete a text index
CDTDeleteQueryIndex *op = [[CDTDeleteQueryIndex alloc] init];
op.indexType = CDTQueryIndexTypeText;
op.indexName = @"example";
op.desginDocName = @"exampleDesignDoc";
op.deleteIndexCompletionBlock = ^(NSInteger status, NSError * _Nullable error){
    if (error) {
        NSLog(@"Failed to delete index");
    } else {
        NSLog(@"Index deleted");
    };

[db addOperation:op];

// Delete a JSON index
let op = CDTDeleteQueryIndex()
op.indexType = .Json
op.indexName = "example"
op.designDocumentName = "exampleDesignDoc"
op.deleteIndexCompletionBlock = {(status, error) -> Void in
      if let _ = error {
          print("Failed to delete index")
      } else {
          print("Index deleted")
      }
}

db.addOperation(op)

// Delete a text index
let op = CDTDeleteQueryIndex()
op.indexType = .Text
op.indexName = "example"
op.designDocumentName = "exampleDesignDoc"
op.deleteIndexCompletionBlock = {(status, error) -> Void in
      if let _ = error {
          print("Failed to delete index")
      } else {
          print("Index deleted")
      }
}
