.h file

#import <UIKit/UIKit.h>

        @interface AddEventViewController : UIViewController <UITextFieldDelegate>

        @end 

.m file

@property (weak, nonatomic) IBOutlet UITextField *textField1;
    @property (weak, nonatomic) IBOutlet UITextField *textField2;
    @property (weak, nonatomic) IBOutlet UITextField *textField3;
    - (IBAction)textFieldReturn:(id)sender;

    @end

    @implementation AddEventViewController

    @synthesize textField1, textField2, textField3;

    - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
    {
        self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
        if (self) {
            // Custom initialization
        }
        return self;
    }

    - (IBAction)textFieldReturn:(id)sender;
    {
        [sender resignFirstResponder];
    }

    - (void)viewDidLoad
    {
        [super viewDidLoad];
        self.textField1.delegate = self;
        textField1.delegate = self;


        // Do any additional setup after loading the view.
    }

    - (void)didReceiveMemoryWarning
    {
        [super didReceiveMemoryWarning];
        // Dispose of any resources that can be recreated.
    }

    - (void)touchesBegan: (NSSet *) touches withEvent: (UIEvent *)event
    {
        if (textField1)
        {
            if ([textField1 canResignFirstResponder]) [textField1 resignFirstResponder];
        }
        [super touchesBegan: touches withEvent: event];

        if (textField2)
        {
            if ([textField2 canResignFirstResponder]) [textField2 resignFirstResponder];
        }
        [super touchesBegan: touches withEvent: event];

        if (textField3)
        {
            if ([textField3 canResignFirstResponder]) [textField3 resignFirstResponder];
        }
        [super touchesBegan: touches withEvent: event];
    }


    - (BOOL)textFieldShouldReturn:(UITextField *)textField
    {
        [textField1 resignFirstResponder];
        return NO;

        [textField2 resignFirstResponder];
        return NO;

        [textField3 resignFirstResponder];
        return NO;
    }

    @end

Ok so im getting the yellow bug symbol on the lines:

    - (void)viewDidLoad
    {
      [super viewDidLoad];
        self.textField1.delegate = self;
        textField1.delegate = self;
    }

I don’t know how to delegate all of my textFields? how do i make this textFieldReturn work for all of my textFields.. that viewDidLoad area has to be the problem, because everything else works good…

Answer 1

Switch UITextViewDelegate to UITextFieldDelegate in your header file. This should do it. Let me know if you still have trouble.
