Adding MKInputBoxView To Your Project


CocoaPods is the recommended way to add MKInputBoxView to your project. Just add

pod 'MKInputBoxView'

and run
pod install. It will install the most recent version of MKInputBoxView.

If you would like to use the latest code of MKInputBoxView use:

pod 'MKInputBoxView', :head

Alternatively, just add MKInputBoxView.hand MKInputBoxView.m to your project.


Creating an input box

MKInputBoxView *inputBoxView = [MKInputBoxView boxOfType:NumberInput];
[inputBoxView show];

Available styles:

  • PlainTextInput – Simple text field
  • NumberInput – Text field accepting numbers only – numeric keyboard
  • PhoneNumberInput – Text field accepting numbers only – phone keyboard
  • EmailInput – Text field accepting email addresses – email keyboard
  • SecureTextInput – Secure text field for passwords
  • LoginAndPasswordInput – Two text fields for user and password entry

Customising the box

Changing the blur effect (UIBlurEffectStyle: ExtraLight, Light, Dark).

[inputBoxView setBlurEffectStyle:UIBlurEffectStyleDark];

Set title and message.

[inputBoxView setTitle:@"Who are you?"];
[inputBoxView setMessage:@"Please enter your username and password to get access to the system."];

Set text of the buttons

[inputBoxView setSubmitButtonText:@"OK"];
[inputBoxView setCancelButtonText:@"Cancel"];

Decimals for the NumberInput type. Default is 0. If set, the user input will be converted to Double with 2 decimals.

[inputBoxView setNumberOfDecimals:2];

Easy way to manipulate the textField’s properties.

inputBoxView.customise = ^(UITextField *textField) {
    textField.placeholder = @"Your eMail address";
    if (textField.secureTextEntry) {
        textField.placeholder = @"Your password";
    textField.textColor = [UIColor whiteColor];
    textField.layer.cornerRadius = 4.0f;
    return textField;

Closures for submission and cancellation

inputBoxView.onSubmit = ^(NSString *value1, NSString *value2) {
    NSLog(@"user: %@", value1);
    NSLog(@"pass: %@", value2);
    if ([value1 isValid] && [value2 isValid]){
    return YES; // YES to hide the inputBoxView
    } else {
    return NO; // NO will keep the inputBoxView open
inputBoxView.onCancel = ^{
