xcode textfield to NSURL path - xcode

Question

I am trying to get a URL from my user in a TextField and then process the result. Presently an exception is being thrown with the following -[UITextField length]: unrecognized selector sent to instance in the NSURLRequest below when I supply URLWithString: (NSString *)self.urlNameInput].
myViewController.h
#class myViewController;
#interface myViewController : UIViewController <UITextFieldDelegate, NSURLConnectionDataDelegate, NSURLConnectionDelegate>
{
NSMutableData *receivedData;
}
#property (weak, nonatomic) IBOutlet UITextField *urlNameInput;
#property (nonatomic, retain) IBOutlet UINavigationController *navigationController;
#end
myViewController.m
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
if (textField == self.urlNameInput) {
[textField resignFirstResponder];
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString: (NSString *)self.urlNameInput] cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
// create the connection with the request
// and start loading the data
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if (theConnection) {
// Create the NSMutableData to hold the received data.
// receivedData is an instance variable declared elsewhere.
receivedData = [NSMutableData data] ;
} else {
// Inform the user that the connection failed.
NSLog(#"Their is an error with that URL.");
}
}
return YES;
}

I think your mistake is, that you pass an UITextField to a method expecting a NSString.
Change
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString: (NSString *)self.urlNameInput] cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
to
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:self.urlNameInput.text] cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
