Posted by codingtag on September 28th, 2019

They probably come with a revolutionizing UI with great functionality which, in turn, increases their applications. The implementation of iOS gives rise to career opportunities for application developers. They can read the iOS interview questions to face the challenge of impressing the recruiters. In this blog, I am going to explore the concept of the NSURLConnection class on iOS.

Are you wanted to know how to load content on iOS?

It can be done through the NSURLConnection class. 

NSURLConnection objects permit developers to load the URL’s content through a URL request object.

This class has been utilized as a session layer in order to control the entire network communication including creation and network release.   The session object is created by the NSURLConnection class which is then shared between the applications and for their default configuration. This class provides an equitable default behavior. Moreover, it permits to fetch the content present in a URL through less code.  One can initiate and terminate URL requests in iOS through NSURLConnection objects.

NSURLConnection Protocols:

Three protocols are usually incorporated with NSURLConnection class which were named NSURLConnectionDelegate,  NSURLConnectionDownloadDelegate, and NSURLConnectionDataDelegate.

To implement these three protocols, there is a need to write a class and method that imitates them. After a class creation and selecting a suitable method, the class instance is created as the delegate.

Major Highlights of NSURLConnection class:

During iOS application development, when some situations arise like there is a need of retrieving some contents of a URL along with delegates or URL requests management including custom authentication, data acquiring, and redirection then developers make use of NSURLConnection section class.

NSURLConnection class is also implemented by the developer to make the application compatible with advanced iOS.

Conclusion:

We have discussed some major points related to the NSURLConnection class that plays a prime role during application development in iOS to build an NSURLSession object to capture configuration selections and multiple task management. The in-depth knowledge of the mentioned-above concept might be a great boost during the interview. So, aspirants are required to read thoroughly each class during preparation. Along with iOS highlights, If they refer to Desktop Support interview questions, this can become a plus point as sometimes recruiters simply ask questions related to basic networking questions too to verify your state of mind.
