2014-02-13 13:47:14.863 Ribbit[23778:70b] -[SignupViewController passwordField:]: unrecognized selector sent to instance 0x9a6d230 (lldb)
I keep getting this message. When I switch fields in a signup page. I have username password and email. I enter username and password perfectly but when i click email the thing just shuts down and stops

You had a few unnecessary actions connected to the email and password text fields for some reason (didEndEditing and a few others) that were causing problems. you can fix it yourself by removing your text field connections on your sign up view controller and deleting the declarations in your .h for sign up, then just reconnect everything and name them usernameField, passwordField, and emailField and it will work.

It was a relatively simple problem that was hard to diagnose without actually looking at the project and the connections. I noticed you had some weird actions connected to your text fields (instead of just the outlet connections you had a few more) removed your text field connections and re added and it doesnt crash anymore. Isnt debugging fun!
David Greenstein
6,734 Pointsis this going to mess up my parse thing though because its a different file
Stone Preston
42,016 Pointseh it shouldnt. But if I were you I would just do what I Did in your own project. remove all the outlet connections and actions associated with your text fields in the connections inspector of your signup view controller (on the far right of xcode in the utiities view with your view controller selected press the arrow button at the top to view connections). delete anything that has to do with your text fields. including actions (but not your sign up button action). then delete the outlet declarations for your textfields in your .h, then add the connections again by control clicking and dragging from each text field to your .h
David Greenstein
6,734 Pointsi jsut looked at your file and took what you took out and then did the same on my file
Stone Preston
42,016 Pointsalright is it working?
David Greenstein
6,734 Pointsis it weird that all i had to do was that first step. I didnt have to control click and drag in the .h file and its working apparently fine no errors
Stone Preston
42,016 Pointsnot sure. i would connect it if i were you just to be safe.
David Greenstein
6,734 Pointscan i ask you one more question?
Stone Preston
42,016 Pointssure whats up
David Greenstein
6,734 Pointson the last } at the bottom. it keeps saying control reaches end of non-void function how do i fix this?
pragma mark - Table view delegate
-
(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [self.tableView deselectRowAtIndexPath:indexPath animated:NO];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; cell.accessoryType =UITableViewCellAccessoryCheckmark;
PFUser *user = [self.allUsers objectAtIndex:indexPath.row]; PFRelation *friendsRelation = [self.currentUser relationForKey:@"friendsRelation"]; [friendsRelation addObject:user]; [self.currentUser saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) { if (error) { NSLog(@"Error %@ %@", error, [error userInfo]); } }]; }
pragma mark - Helper methods
- (BOOL)isFriend:(PFUser *)user {
}
@end
Stone Preston
42,016 Pointsok your isFriend method has a return type of BOOL, which means inside the method you will have to return a BOOL. If you are following along in the videos im sure it does this at some point so just keep watching.
David Greenstein
6,734 Pointsin the video however it does not have error at this point
David Greenstein
6,734 Pointsdo u see any error?
Stone Preston
42,016 Pointswell yes, the error is your function has a return type of bool and you arent returning anything. Thats what the control reaches end of non void function means, it gets to the end without there being anything returned. but if ben doesnt have anything in that method at this point just keep following along and it will be implemented correctly.
David Greenstein
6,734 Pointsits the } before the @end
David Greenstein
6,734 Pointsi fixed my other problems but in the create your own destroying messaging app. I have an error with the line self.videoFilePath = [[info objectForKey:UIImagePickerControllerMediaURL] path]; It says implicit conversion of C pointer type 'CGPathRef (aka 'const struct CGPath *) to Objective-C pointer type 'NSString *' requires a bridged cast. What does this mean?
Stone Preston
42,016 Pointssee the teachers notes in this video. it mentions splitting that line into two parts.
replace
self.videoFilePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];
with
NSURL *imagePickerURL = [info objectForKey:UIImagePickerControllerMediaURL]; self.videoFilePath = [imagePickerURL path];
