BMInputBox

BMInputBox is an iOS drop-in class wrote in Swift that displays input boxes for the user to input different kinds of data, for instance username and password, email address, numbers, plain text. BMInputBox is meant as a replacement for the limited UIAlertView input options.

Requirements

Built in Swift 4 for iOS 10.0+. All devices supported. BMInputBox can be used in both Swift and in ObjectiveC projects.

Adding BMInputBox To Your Project

CocoaPods

CocoaPods is the recommended way to add BMInputBox to your project. As BMInputBox is written in Swift, you need to add the use_frameworks! option to your podfile.

pod 'BMInputBox'

Usage

Import the module to your project.

import BMInputBox

Creating an input box

let inputBox = BMInputBox.boxWithStyle(.NumberInput)
inputBox.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

Blur Effect

UIBlurEffectStyle: .extraLight, .light, .dark

inputBox.blurEffectStyle = .light

Custom Texts And I18n

You can set a custom text for all the components in the view. See also the Validation section.

inputBox.title = NSLocalizedString("This Is The Title", comment: "")
inputBox.message = NSLocalizedString("This is the message in the view, can be as long as three lines.", comment: "")
inputBox.submitButtonText = NSLocalizedString("OK", comment: "")
inputBox.cancelButtonText = NSLocalizedString("Cancel", comment: "")
inputBox.validationLabelText = NSLocalizedString("Text must be 6 characters long.", comment: "")

Mandatory Decimals

For the .NumberInput type. Default is 0. If set, the user input will be convertd to Double with 2 decimals. For instance "1" becomes "0.01" and "1234" becomes "12.34".

inputBox.numberOfDecimals = 2

Going Crazy

Doing whatever you need with the textField in the box.

inputBox.customiseInputElement = {(element: UITextField) in
  element.placeholder = "Custom placeholder"
  if element.secureTextEntry == true {
    element.placeholder = "Secure placeholder"
  }
  return element
}

Validation

Minimum And Maximum Values

Setting minimum and maximum values for the .NumberInput type. Shows a message to the user below the textField. The entered value is validated against these values.

Setting a minimum value:

inputBox.minimumValue = 10
inputBox.validationLabelText = "A number greater %@."

Setting minimum and maximum values:

inputBox.minimumValue = 10
inputBox.maximumValue = 30
inputBox.validationLabelText = "A number between %@ and %@."

Text Length

Setting minimum and maximum lenght of the entered text. If the values are the same, it will check for an exact length.

inputBox.minimumLenght = 4
inputBox.maximumLength = 6
inputBox.validationLabelText = "A text between %i and %i characters."

Optional Input

When setting the box to be optional, nil values will be accepted as well. However, if text is entered, it will be validated agains the rest of the properties above.

inputBox.isOptional = true

Closures For Events

Submit

inputBox.onSubmit = {(value: AnyObject...) in
  for text in value {
    if text is String {
      NSLog("%@", text as String)
    }
    else if text is NSDate {
      NSLog("%@", text as NSDate)
    }
    else if text is Int {
      NSLog("%i", text as Int)
    }
  }
}

Cancel

inputBox.onCancel = {
  NSLog("Cancelled")
}

Tuples in Objective C are not supported, therefore, you have to use the onSubmitObjc closure if your project is in Objective C. This returns an array with the values of the Input Box.

inputBox.onSubmitObjc = {(values: [AnyObject]) in
  for text in values {
    if text is String {
      NSLog("%@", text as String)
    }
    else if text is NSDate {
      NSLog("%@", text as NSDate)
    }
    else if text is Int {
      NSLog("%i", text as Int)
    }
  }
}

Change

You can interact with the text as it is being entered. The closure is tied to the .editingChanged event of the UITextField.

inputBox.onChange = {(value: String) in
  return value.uppercaseString
}
