textFieldShouldReturn does not get called (textField loaded programmatically)

Question

I'm currently loading a -UITextField programmatically and trying to make the keyboard go down once I click on 'Search'.

I declare the -UITextFeild inside the .m file as UITextField *searchTextField;

Inside the .h file I do indeed declare the -UITextField's delegate

@interface firstChannel : UIViewController<LBYouTubePlayerControllerDelegate, UITableViewDelegate,UITableViewDataSource, NSXMLParserDelegate, UITextFieldDelegate, AVPlayerItemOutputPullDelegate>{

This is how I add the UITextField programmatically.

 searchTextField = [[UITextField alloc] initWithFrame:CGRectMake(10, -26, 300, 30)]; searchTextField.borderStyle = UITextBorderStyleRoundedRect; searchTextField.font = [UIFont fontWithName:@"Heiti TC" size:13]; searchTextField.autocorrectionType = UITextAutocorrectionTypeNo; searchTextField.clearButtonMode = UITextFieldViewModeWhileEditing; searchTextField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; searchTextField.placeholder = @"Search on the Channel"; searchTextField.borderStyle = UITextBorderStyleNone;; searchTextField.textAlignment = UITextAlignmentCenter; searchTextField.center = CGPointMake(160, 43); searchTextField.textColor = [UIColor colorWithRed:(232.0/255.0) green:(232.0/255.0) blue:(232.0/255.0) alpha:(100.0/100.0)]; searchTextField.clearButtonMode = UITextFieldViewModeNever; searchTextField.returnKeyType = UIReturnKeySearch; [searchTextField setKeyboardAppearance:UIKeyboardAppearanceAlert]; [self.view.window addSubview:searchTextField]; [searchTextField becomeFirstResponder];

I added the delegate inside -viewDidLoad

searchTextField.delegate = self;

However when I click on "Search" on the keyboard nothing happens. I'm unsure why that's happening I've even debugged it by logging something once you hit returns but nothing happens.

I forgot to mention that inside -viewDidLoad I did add searchTextField.delegate = self; — Gretar Agnarsson

@GretarAgnarsson Is the call to searchTExtField.delegate made before or after you create and setup the text field? Make sure it is done after. — rmaddy

I was calling it before the textField was created, I called it now after it was created and it works, thanks @rmaddy — Gretar Agnarsson

Call the searchTExtField.delegate after you create and setup the text field.

Try moving all the code in viewDidLoad

 - (void)viewDidLoad { [super viewDidLoad]; searchTextField = [[UITextField alloc] initWithFrame:CGRectMake(10, -26, 300, 30)]; searchTextField.borderStyle = UITextBorderStyleRoundedRect; searchTextField.font = [UIFont fontWithName:@"Heiti TC" size:13]; searchTextField.autocorrectionType = UITextAutocorrectionTypeNo; searchTextField.clearButtonMode = UITextFieldViewModeWhileEditing; searchTextField.delegate = self; searchTextField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; searchTextField.placeholder = @"Search on the Channel"; searchTextField.borderStyle = UITextBorderStyleNone;; searchTextField.textAlignment = UITextAlignmentCenter; searchTextField.center = CGPointMake(160, 43); searchTextField.textColor = [UIColor colorWithRed:(232.0/255.0) green:(232.0/255.0) blue:(232.0/255.0) alpha:(100.0/100.0)]; searchTextField.clearButtonMode = UITextFieldViewModeNever; searchTextField.returnKeyType = UIReturnKeySearch; [searchTextField setKeyboardAppearance:UIKeyboardAppearanceAlert]; [self.view.window addSubview:searchTextField]; [searchTextField becomeFirstResponder]; }

Also, if you are using search bar then you need to use search bar delegate. If you are just using UITextfield, then you should be okay.

Have you implemented the delegate method (this method gets called when the user taps the return key):

- (BOOL)textFieldShouldReturn:(UITextField *)textField { [textField resignFirstResponder]; //Perform search with text: [self performSearch:[textField text]]; return NO; }

This will resign the responder. Here you can also call your search method.
