Hpple Implementation/unrecognized Selector

I am working with the hpple html parser here: https://github.com/topfunky/hpple To test the function I've added it to a simple project and am able to compile and open the simulator

Solution 1:

Here's your problem:

NSData *htmlData = [NSString stringWithContentsOfURL:[NSURL URLWithString: urlRequest] encoding:NSUTF8StringEncoding error:nil];

TFHpple *xpathParser = [[TFHpple alloc] initWithHTMLData:htmlData];

TFHpple's initWithHTMLData is supposed to take an NSData. You declare htmlData to be an NSData, but the actual object you're assigning to it is an NSString.

This should fix it:

NSData *htmlData = [NSData dataWithContentsOfURL:[NSURL URLWithString: urlRequest]];
