I am trying to use: checkResourceIsReachableAndReturnError of NSURL class
But I always get FALSE and the NSError shows : Domain=NSCocoaErrorDomain Code=4 “The operation couldn’t be completed. (Cocoa error 4.)”
I checked the URL with safary and it works, any idea?
This is not the method you are looking for. The description of the method in NSURL’s class reference states:
Returns whether the resource pointed to by a file URL can be reached.The method should be used to test reachability of file URLs, you cannot check whether an internet resource is available or not using this method.
You’ll find several answers in stack overflow if you search for reachability testing or something similar.. However, you could probably just attempt to reach the URL and handle the error if that fails.
