Get Reactions from Timeline Post via Facebook Graph API – Swift – iOS

February 7, 2021April 13, 2016 by Ashish Kakkad

New version of SDK is 4.16.x(Swift) and Graph API Version is 2.8.
With the Graph API 2.6 Facebook has given support to fetch (read only) the Reactions on Timeline Posts.

Post is updated for iOS 10 and Swift 3

API documentation is available here.

Let’s learn how to get reactions from the post

Install pods

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'
target 'FBSwiftLogin' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!
  # Pods for FBSwiftLogin
    pod 'FacebookCore'
    pod 'FacebookLogin'
end

# Uncomment the next line to define a global platform for your project

platform :ios, '9.0'

target 'FBSwiftLogin' do

# Comment the next line if you're not using Swift and don't want to use dynamic frameworks

use_frameworks!

# Pods for FBSwiftLogin

pod 'FacebookCore'

pod 'FacebookLogin'

end

Login with Facebook

I have already written a tutorial on Facebook Login.

Get Facebook Posts via Graph API

We can get the Facebook post via graph API : /me/posts for that we have to add user_posts permission with login.

func getFacebookUserPosts() {
    FBSDKGraphRequest(graphPath: "/me/posts", parameters: nil, httpMethod: "GET").start(completionHandler: { (connection, result, error) in
        if (error == nil){
            print(result)
        }
    })
}

func getFacebookUserPosts() {

FBSDKGraphRequest(graphPath: "/me/posts", parameters: nil, httpMethod: "GET").start(completionHandler: { (connection, result, error) in

if (error == nil){

print(result)

}

})

}

Get Reactions from one of the Post

We can get the Facebook post reactions via graph API : /{post-id}/reactions. We have to pass parameters like fields and summary as described in getReactions function.
Note : Here I am writing sample for only first post.

func getFacebookUserPosts() {
    var strGraphPath : String = ""
    FBSDKGraphRequest(graphPath: "/me/posts", parameters: nil, httpMethod: "GET").start(completionHandler: { (connection, result, error) in
        if (error == nil){
            print(result)
            let data = (result as! [String : Any])["data"] as! [[String : Any]]
            if(data.count > 0) {
                let strId = data[0]["id"] as! String
                strGraphPath = "/"+strId+"/reactions"
                self.getReactions(strGraphPath)
            }
        }
    })
}
func getReactions(_ strGraphPath:String) {
    FBSDKGraphRequest(graphPath: strGraphPath, parameters: ["fields":"id, name, type", "summary":"total_count, viewer_reaction"], httpMethod: "GET").start(completionHandler: { (connection, result, error) in
        if (error == nil){
            print(result)
        }
    })
}

func getFacebookUserPosts() {

var strGraphPath : String = ""

FBSDKGraphRequest(graphPath: "/me/posts", parameters: nil, httpMethod: "GET").start(completionHandler: { (connection, result, error) in

if (error == nil){

print(result)

let data = (result as! [String : Any])["data"] as! [[String : Any]]

if(data.count > 0) {

let strId = data[0]["id"] as! String

strGraphPath = "/"+strId+"/reactions"

self.getReactions(strGraphPath)

}

})

}

func getReactions(_ strGraphPath:String) {

FBSDKGraphRequest(graphPath: strGraphPath, parameters: ["fields":"id, name, type", "summary":"total_count, viewer_reaction"], httpMethod: "GET").start(completionHandler: { (connection, result, error) in

if (error == nil){

print(result)

}

})

}

Response should be like

Type of reactions : NONE, LIKE, LOVE, WOW, HAHA, SAD, ANGRY

{
    data =     (
        {
            id = ACCOUNT_ID;
            name = "NAME";
            type = HAHA;
        },
        {
            id = ACCOUNT_ID;
            name = "NAME";
            type = LIKE;
        }
    );
    paging =     {
        cursors =         {
            after = REFERENCE_ID;
            before = REFERENCE_ID;
        };
        next = "NEXT_REFERENCE_LINK";
    };
    summary =     {
        "total_count" = 56;
        "viewer_reaction" = NONE;
    };
}

{

data = (

{

id = ACCOUNT_ID;

name = "NAME";

type = HAHA;

{

id = ACCOUNT_ID;

name = "NAME";

type = LIKE;

}

);

paging = {

cursors = {

after = REFERENCE_ID;

before = REFERENCE_ID;

};

next = "NEXT_REFERENCE_LINK";

};

summary = {

"total_count" = 56;

"viewer_reaction" = NONE;

};

}

How to create a wrapper for Alamofire and SwiftyJSON? Swift – iOS

February 7, 2021March 9, 2016 by Ashish Kakkad

This blogpost updated with Swift 3 – Xcode 8 – iOS 10 – Alamofire 4.0

I have posted a basic tutorial about Alamofire and SwiftyJSON How to use Alamofire and SwiftyJSON with Swift?
And some day before we have learned about Use of Blocks(Closures) or Completion Handlers with Function in Swift – iOS
Let’s combine both the topics to make a WRAPPER of Alamofire and SwiftyJSON.

Use of Blocks(Closures) or Completion Handlers with Function in Swift – iOS

February 7, 2021February 28, 2016 by Ashish Kakkad

Blocks in Objective-C

In Objective-C we are using the blocks(completion handlers) with functions as follows :

[code language=”obj-c”]
– (void)yourFunctionName:(NSString *)yourString withCompletionHandler:(void (^)(NSString *yourResult))block;
[/code]

Closures in Swift

Closures are self-contained blocks of functionality that can be passed around and used in your code. Closures in Swift are similar to blocks in C and Objective-C and to lambdas in other programming languages.

Syntax with Function

[code language=”obj-c”]
func yourFunctionName(parameter:Type, … , withCompletionHandler:(result:Type) -> Void)
[/code]
For more closure syntax : goshdarnclosuresyntax.com

Example

Function Definition:
[code language=”obj-c”]
func closureReturn(isTest:Bool, withCompletionHandler:(result:String) -> Void) {
if(isTest){
withCompletionHandler(result: "Yes")
}
else{
withCompletionHandler(result: "No")
}
}
[/code]
Calling Function:
[code language=”obj-c”]
closureReturn(true) { (result) -> Void in
print(result)
}
[/code]
Output should be respective to value true/false.

In next post I will write a tutorial on a wrapper class for Alamofire with use of SwiftyJSON by using closures.

Happy Coding 🙂

How to use Alamofire and SwiftyJSON with Swift? – Swift 3 – iOS 10 – Xcode 8

How to work with IBDesignable and IBInspectable in Swift Language?

February 7, 2021August 8, 2015 by Ashish Kakkad

How to use the @IBDesignable and @IBInspectable?

By giving you a simple example that we can not change the corner radius from the design view. We have to change it run time. If you want to make possible it with design time then you can use the @IBDesignable and @IBInspectable.

So, We are taking an example as IBButtonExtender for this the functionality

Border Color
Border Width
Corner Radius

Create an Custom Class for UIButton with @IBDesignable

@IBDesignable
class ButtonExtender: UIButton {
}

@IBDesignable

class ButtonExtender: UIButton {

}

Create an @IBInspectable for Inspect the element. the Border Color property will be added to the list in the right panel when you create button with this class.

@IBInspectable var borderColor: UIColor = UIColor.white {
    didSet {
        layer.borderColor = borderColor.cgColor
    }
}

@IBInspectable var borderColor: UIColor = UIColor.white {

didSet {

layer.borderColor = borderColor.cgColor

}

Set Initialization functions and other @IBInspectable as above.
You can check the code for the ButtonExtender.swift

IBButtonExtender

Presenting the ButtonExtender for Border Color, Border Width and Corner Radius function with the @IBDesignable and @IBInspectable in the Swift Language.

By making some corner radius and colors, You will get neat and clean output.

Github

Find IBButtonExtender on github 🙂
Check other articles on Swift Language.
All suggestions are acceptable. Put it in the comments!
Happy Coding 🙂

How to add an Objective-C file in your Swift Project? or How to set Objective-C bridging header?

February 7, 2021December 8, 2014 by Ashish Kakkad

To import a set of Objective-C files in the same app target as your Swift code, you rely on an Objective-C bridging header to expose those files to Swift. Xcode offers to create this header file when you add an Objective-C file to an existing Swift app.

If you accept, Xcode creates the header file along with the file you were creating, and names it by your product module name followed by adding “-Bridging-Header.h”.

Alternatively, you can create a bridging header yourself by choosing File > New > File > (iOS or OS X) > Source > Header File.

You’ll need to edit the bridging header file to expose your Objective-C code to your Swift code.

To import Objective-C code into Swift from the same target

In your Objective-C bridging header file, import every Objective-C header you want to expose to Swift.
For example:
[code language=”obj-c”]
#import "XYZCustomCell.h"
#import "XYZCustomView.h"
#import "XYZCustomViewController.h"
[/code]
Under Build Settings, make sure the Objective-C Bridging Header build setting under Swift Compiler – Code Generation has a path to the header.
The path should be relative to your project, similar to the way your Info.plist path is specified in Build Settings. In most cases, you should not need to modify this setting.

Any public Objective-C headers listed in this bridging header file will be visible to Swift. The Objective-C functionality will be available in any Swift file within that target automatically, without any import statements. Use your custom Objective-C code with the same Swift syntax you use with system classes.

For Example:
[code language=”obj-c”]
let myCell = XYZCustomCell()
myCell.subtitle = "A custom cell"
[/code]

Update : JSON Array Parsing in Swift Language – Swift 3 – iOS 10 – Xcode 8

August 21, 2022October 28, 2014 by Ashish Kakkad

So, how to parse following type of JSON?

"contacts": [
