Why Use Different Input Types?
Keyboard input types help us obtain necessary inputs from users.
It removes unnecessary keys and includes the required ones. Users can set the input type using the keyboard property of UITextField.
- For example: textField.keyboardType = UIKeyboardTypeDefault

Adding Custom Method addTextFieldWithDifferentKeyboard
-(void) addTextFieldWithDifferentKeyboard{
UITextField *textField1 = [[UITextField alloc]initWithFrame:
CGRectMake(20, 50, 280, 30)];
textField1.delegate = self;
textField1.borderStyle = UITextBorderStyleRoundedRect;
textField1.placeholder = @"Default Keyboard";
[self.view addSubview:textField1];
UITextField *textField2 = [[UITextField alloc]initWithFrame:
CGRectMake(20, 100, 280, 30)];
textField2.delegate = self;
textField2.borderStyle = UITextBorderStyleRoundedRect;
textField2.keyboardType = UIKeyboardTypeASCIICapable;
textField2.placeholder = @"ASCII keyboard";
[self.view addSubview:textField2];
UITextField *textField3 = [[UITextField alloc]initWithFrame:
CGRectMake(20, 150, 280, 30)];
textField3.delegate = self;
textField3.borderStyle = UITextBorderStyleRoundedRect;
textField3.keyboardType = UIKeyboardTypePhonePad;
textField3.placeholder = @"Phone pad keyboard";
[self.view addSubview:textField3];
UITextField *textField4 = [[UITextField alloc]initWithFrame:
CGRectMake(20, 200, 280, 30)];
textField4.delegate = self;
textField4.borderStyle = UITextBorderStyleRoundedRect;
textField4.keyboardType = UIKeyboardTypeDecimalPad;
textField4.placeholder = @"Decimal pad keyboard";
[self.view addSubview:textField4];
UITextField *textField5 = [[UITextField alloc]initWithFrame:
CGRectMake(20, 250, 280, 30)]; textField5.delegate = self; textField5.borderStyle = UITextBorderStyleRoundedRect; textField5.keyboardType = UIKeyboardTypeEmailAddress; textField5.placeholder = @"Email keyboard"; [self.view addSubview:textField5];
UITextField *textField6= [[UITextField alloc]initWithFrame: CGRectMake(20, 300, 280, 30)]; textField6.delegate = self; textField6.borderStyle = UITextBorderStyleRoundedRect; textField6.keyboardType = UIKeyboardTypeURL; textField6.placeholder = @"URL keyboard"; [self.view addSubview:textField6]; }
Update `viewDidLoad` in `ViewController.m` as shown below:
(void)viewDidLoad { [super viewDidLoad]; //The custom method to create textfield with different keyboard input [self addTextFieldWithDifferentKeyboard]; //Do any additional setup after loading the view, typically from a nib }
## Output

Now when we run the application, we will get the following output:
Selecting different text fields will show different keyboards.
