I wanted to know if it is possible and if so how to know the url you are accessing via objective-c takes you to the correct webpage. To elaborate further:
If a user is using an app that connects to a webpage to get it’s data, and if this user is say at an airport. The internet connection at airport in many cases will redirect u to their webpage (regardless of what url u maybe type) where u have to either pay or something to get any further internet access. Thus if a app needing data from a webpage is used without user’s knowledge of this limited access to internet, i want to display a popup message that informs the user saying something that the webpage it tried to access was required to a different webpage thus cannot access data. As oppose to getting false data and the user thinking the app is buggy.
Is there a way to do this. Thanks in advance for all of your help.
If you are using
NSURLConnectionyou can implement theNSURLConnectionDelegatemethodwhich is called if it is determined that the request must redirect to a new location. The delegate can the choose to allow the redirect, modify the destination, or deny the redirect.
