Rundown of NSURLConnection Class in iOS
by Coding Tag CodingtagAs we all know, how the iPhone is rapidly growing with its iOS
operating system. 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.
