Courses Plus Student 65 PointsNavigation Controller between view controller and table view controller
Any ideas on how to add a Navigation Controller in iOS7 between a Table View and View Controller. As soon as I embed the Navigation Controller to the table view the app crashes. With out the navigation controller it works fine. But then the Table View becomes a View Controller. This is the code I'm using:
[self.navigationController performSegueWithIdentifier:@"setup" sender:self];

This is the code:
<p>
- (IBAction)signup:(id)sender {
NSString *username = [self.usernameField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSString *password = [self.passwordField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSString *email = [self.emailField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
if ([username length] == 0 || [password length] == 0 || [email length] == 0) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Please try again."
message:@"Make sure you enter all fields."
delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alertView show];
}
else {
PFUser *newUser = [PFUser user];
newUser.username = username;
newUser.password = password;
newUser.email = email;
[newUser signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (error) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Sorry!"
message:[error.userInfo objectForKey:@"error"]
delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alertView show];
}
else {
[self.navigationController performSegueWithIdentifier:@"setup" sender:self];
}
}];
}
}
</p>

14,957 Pointsremove that:
else {
[self.navigationController performSegueWithIdentifier:@"setup" sender:self];
}

Courses Plus Student 65 PointsBut how do I get to the next controller then?
Thomas Nilsen
14,957 PointsIf your segue is connected from the "Sign Up" button, and it's a push-segue you don't need it. I should have explained a bit instead of just showing code.
Take a look at this example: https://www.dropbox.com/sh/otilgs627pksjke/p2II6Sk2Dh

Courses Plus Student 65 PointsThanks man. Do you have the whole project so I can try it out?
Thomas Nilsen
14,957 PointsWhat do you mean? That was just something I made to make it easier to understand :)
Nicolaus Nsarray
Courses Plus Student 65 PointsYes. But you cant open the project with only one file. Everything is missing
Thomas Nilsen
14,957 PointsThat's strange. I can mail it to you. What's your email?
Nicolaus Nsarray
Courses Plus Student 65 PointsThanks it worked out anyway
