Custom controls to turn UITextfields into item-selection with picker and date-selections.
Step 1. pod 'SRKControls', '~> 3.0.1'
Step 2. After above pod-line, add line use_frameworks!
Step 3. pod install
Step 4. Go to your ViewController.swift & import SRKControls
Step 5. Go to your ViewController.xib or Main.Storyboard, drag & drop UITextField object on user-interface. Connect delegate of that textField-object.
Step 6. Change textField-Object class to SRKComboBox or SRKDateTimeBox as per your need. Also have an IBOutlet Connection to your ViewController.
Step 7. Add UITextFieldDelegate, SRKComboBoxDelegate and / or SRKDateTimeBoxDelegate as per your need.
Step 8. Put following lines of code
// Some sample objects.
@IBOutlet weak var myComboBox:SRKComboBox!
@IBOutlet weak var myDateBox:SRKDateTimeBox!
@IBOutlet weak var myTimeBox:SRKDateTimeBox!
// Some sample array
let arrayForComboBox = ["Sagar", "Sagar R. Kothari", "Kothari", "sag333ar", "sag333ar.github.io", "samurai", "jack", "cartoon", "network"]
//MARK:- UITextFieldDelegate
func textFieldShouldBeginEditing(textField: UITextField) -> Bool {
if let txt = textField as? SRKComboBox {
txt.delegateForComboBox = self
txt.showOptions()
return false
}
if let txt = textField as? SRKDateTimeBox {
txt.delegateForDateTimeBox = self
txt.showOptions()
return false
}
return true
}

}
func comboBoxDidTappedDone(textField:SRKComboBox) {
print("Let's do some action here")
}
//MARK:- SRKDateTimeBoxDelegate
func dateTimeBox(textField:SRKDateTimeBox, didSelectDate date:NSDate) {
let df = NSDateFormatter()
if textField == self.myDateBox {
df.dateFormat = "dd-MMM-yyyy"
self.myDateBox.text = df.stringFromDate(date)
} else if textField == self.myTimeBox {
df.dateFormat = "HH:mm"
self.myTimeBox.text = df.stringFromDate(date)
}
}
func dateTimeBoxType(textField:SRKDateTimeBox) -> UIDatePickerMode {
if textField == self.myDateBox {
return UIDatePickerMode.Date
} else if textField == self.myTimeBox {
return UIDatePickerMode.Time
} else {
return UIDatePickerMode.Date
}
}
func dateTimeBoxMinimumDate(textField:SRKDateTimeBox) -> NSDate? {
return nil
}
func dateTimeBoxMaximumDate(textField:SRKDateTimeBox) -> NSDate? {
return nil
}
func dateTimeBoxPresentingViewController(textField:SRKDateTimeBox) -> UIViewController {
return self
}
func dateTimeBoxRectFromWhereToPresent(textField:SRKDateTimeBox) -> CGRect {
return textField.frame
}
func dateTimeBoxFromBarButton(textField:SRKDateTimeBox) -> UIBarButtonItem? {
return nil
}
func dateTimeBoxTintColor(textField:SRKDateTimeBox) -> UIColor {
return UIColor.blackColor()
}
func dateTimeBoxToolbarColor(textField:SRKDateTimeBox) -> UIColor {
return UIColor.whiteColor()
}
func dateTimeBoxDidTappedCancel(textField:SRKDateTimeBox) {
textField.text = ""
}
func dateTimeBoxDidTappedDone(textField:SRKDateTimeBox) {
print("Let's do some action here")
