Core Spotlight , NSUserActivity with supports Call

-
To add a NSUseActivity with a call contact feature , is quite useful to have a better user experience for your app. even when it's not active.

In case you need to refer to some basic's please refer to my previous page.

With this blog today we will see how to use , NSUserActivity a supportCall feature.

For example in your app. you have ability to add local mechanic where you had performed  last service , next appointment so on and so forth.

The code is quite simple and straight forward nothing much fancy here.

  func addLocalMechanicContactActivity(){  
     let localContact = NSUserActivity(activityType: "yourDomain.contact")  
     localContact.title = "Local Mechanic Contact"  
     localContact.userInfo = ["groupId":"20"]  
     localContact.isEligibleForSearch = true  
     localContact.becomeCurrent()  
     localContact.contentAttributeSet = CSSearchableItemAttributeSet(itemContentType: kUTTypeContact as String)  
     localContact.contentAttributeSet?.contactKeywords = ["Mechanic","Local mechanic"]  
     localContact.contentAttributeSet?.phoneNumbers = ["999-999-9999"]  
     localContact.contentAttributeSet?.supportsPhoneCall = NSNumber(integerLiteral: 1)  
     localContact.contentAttributeSet?.authorNames = ["Ron"]  
     self.localContactUserContact = localContact  
   }

1) Create a NSUserActivity with type , for example

     let localContact = NSUserActivity(activityType: "yourDomain.contact")

2) Assign some required attributes.
Assign some title as it is recommended for all user activity object.
isEligibileForSearch is required to enable it for on-device indexing.
becomeCurrent is required for marking the activity as currently in use by current user.

localContact.title = "Local Mechanic Contact"  
     localContact.userInfo = ["groupId":"20"]  
     localContact.isEligibleForSearch = true  
     localContact.becomeCurrent()

3) Create a Searchable Item of Type Contact.
Note: Here we will need to import CoreServices framework to use KUTTTypeContact.

     localContact.contentAttributeSet = CSSearchableItemAttributeSet(itemContentType: kUTTypeContact as String)  
     localContact.contentAttributeSet?.contactKeywords = ["Mechanic","Local mechanic"]  
     localContact.contentAttributeSet?.phoneNumbers = ["999-999-9999"]  
     localContact.contentAttributeSet?.supportsPhoneCall = NSNumber(integerLiteral: 1)  
     localContact.contentAttributeSet?.authorNames = ["Ron"]

contactKeyWords is optional but it's better to have to increasing the relevancy of the data.
phoneNumbers are required as we are enabling the activity which supports phone call.
supportPhoneCall , set it to 1, to enable the feature.

The final thing is make your contactActivity object strong by creating a local strong reference , declare just below in your UIViewController.

 
 var localContactUserContact:NSUserActivity?

Now, the question is it will work ?
Yes , it will on device it should work as it Call feature is only supported on device.
On simulator you might not be able to see it just like below.

hitTest on iOS to identify the view being hit

HitTest on iOS Use hitTest, to identify the view being tapped. The below method allows us to identify the view being selected. We can use it, to identify the view from which we would like to hide the touch events or identify the view we are interested into. Example: In the below case when we tap on Black View we can show an alert like "Black View tapped!" , if we tap on Red View , we can show an alert  "You are not allowed to tap on Red View" .  override func hitTest ( _ point: CGPoint , with event: UIEvent ?) -> UIView ? { } Here is a simple implementation of the method, to identify the view being hit. View hierarchy being used is listed below:- Blue(parent) - Red(child) - Green(child) - Yellow (child) - Orange (child) - Black (child) - White (child) So lets' start with override of hitTest method.      override func hitTest ( _ point: CGPoint , with event: UIEvent ?) -> UIView ? {         //1         if let viewAvailable = findPoin

CMTimeMakeWithSeconds explained

CMTime  is structure which has two main components,  timeScale  and  value. CMTIME = VALUE  / TIMESCALE where, TimeScale =  fraction of a second each unit in numerator occupies. CMTIME = Value / TimeScale 1)  public   func  CMTimeMake( _  value:  Int64 ,  _  timescale:  Int32 ) ->  CMTime CMTimeMake ( 6000 ,  10 ) Means, there are 6000 units , each unit occupies 1/10 of a second 2)  public   func  CMTimeMakeWithSeconds( _  seconds:  Float64 ,  _  preferredTimescale:  Int32 ) ->  CMTime CMTimeMakeWithSeconds(10.0,500) 10.0 = VALUE /500 Therefore VALUE = 5000 So, there are 5000 units, each occupy 1/500 of a second

Custom Editing Control for UITableViewCell , like iPhone Mail Appliation

Dear Friends, Today, while I was developing a application, I found that I am in need to a custom Editing control. Custom Editing Control are displayed on the left side of the screen. IOS sdk provides two of such kind which we use most of the time UITableViewCellEditingStyleDelete & UITableViewCellEditingStyleInsert  . I will be now discussing the third one, UITableViewCellEditingStyleNone. This can be used to design our own Editing control. How this is going to look like can be fond from below screen shot. Steps to achieve this can be found below: STEP 1: Create A subclass of UITabelViewCell First create a subclass of UITableViewCell, where when the cell object is initialised we will have to add a UIButton to its view. You will also need a offset variable, whose value will be 32.0 in all iPhones. -( id ) initWithCoder:( NSCoder *)aDecoder{          self =[ super initWithCoder :aDecoder];          if ( self ){         offset =32.0;
