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

by

Facebook Reactions
Facebook Reactions

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

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.

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.

Response should be like

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

#Like #Share #React 🙂 😛 😀
Happy coding 🙂

Use of Operator Overloading with Swift

by
apple_swift_logo

I was just going through the Swift document and I found that Swift allow to overload the operator just like as C++ Language. Objective-C doesn’t allow to overload the operator.
As swift document we can also say “Operator Functions”.

Let’s Overload ^ (XOR Operator) to make Power of the value

Function Prototype :
Declare function prototype with left hand side value and right and side value.

Operations in the function :
To make the power of the value we have to apply following operations

Let’s try to use with the operator :

Swift 2.2 Warnings and It's Solutions – Xcode 7.3

by
apple_swift_logo

Xcode 7.3 came with Swift 2.2 Version. I just updated to Xcode 7.3 and found following warnings because of Swift version change.

List of warnings with it’s solution:

  1. ‘var’ parameters are deprecated and will be removed in Swift 3

    2. Warning Function Var
    Warning Function Var

    Warning with:
    [code language=”obj-c”]
    func functionTest(var param:String) {
    print(param)
    }
    [/code]
    Solution:
    [code language=”obj-c”]
    func functionTest(param:String) {
    print(param)
    }
    [/code]
    If you want to update that variable inside the function then you have to create copy of that variable to do operations on that.

  2. Use of string literal for Objective-C selectors is deprecated; use ‘#selector’ instead

    3. Warning Selector
    Warning Selector

    Warning with:
    [code language=”obj-c”]
    btn.addTarget(self, action: "functionName", forControlEvents: UIControlEvents.TouchUpInside)
    [/code]
    OR
    [code language=”obj-c”]
    btn.addTarget(self, action: Selector("functionName"), forControlEvents: UIControlEvents.TouchUpInside)
    [/code]
    Solution:
    [code language=”obj-c”]
    btn.addTarget(self, action: #selector(ViewController.functionName), forControlEvents: UIControlEvents.TouchUpInside)
    [/code]
    Apple Documentation : Added information about the #selector syntax for Objective-C selectors to the Selector Expression section.

  3. ‘++’ is deprecated: it will be removed in Swift 3

    4. Warning ++
    Warning ++

    Warning with:
    [code language=”obj-c”]
    var i = 0
    for str in arrStr {
    print(str)
    i++
    }
    [/code]
    Solution:
    [code language=”obj-c”]
    var i = 0
    for str in arrStr {
    print(str)
    i += 1
    }
    [/code]
    Apple Documentation : Removed discussion of C-style for loops, the ++ prefix and postfix operators, and the — prefix and postfix operators.

  4. C-style for statement is deprecated and will be removed in a future version of Swift

    5. Warning For Statement
    Warning For Statement

    Warning with:
    [code language=”obj-c”]
    for var i=0; i<arrStr.count; i += 1 {
    print(arrStr[i])
    }
    [/code]
    Solution:
    [code language=”obj-c”]
    for i in 0 ..< arrStr.count {
    print(arrStr[i])
    }
    [/code]

  5. __FILE__ is deprecated and will be removed in Swift 3, please use #file

    6. Warning __FILE__
    Warning __FILE__

    Warning with:

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

by

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

by

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.

It will be related to this post How to use Alamofire and SwiftyJSON with Swift? – Swift 2 – iOS 9 – Xcode 7

Happy Coding 🙂
