Using CocoaPods - Coming Soon

FCAlertView is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'FCAlertView'


Clone or Download this Repo. Then simply drag the folder FCAlertView to your Xcode project. Please make sure to drag the whole folder, which includes assets needed for some alert types.


FCAlertView comes with an example app that you can use to try out all of the customizations below. It's recommended that you go through all of the docs before using the example app. To use the example app, clone or download FCAlertView, open and run Example/FCAlertView.xcworkspace.

Adding FCAlertView

Start by adding the following to your desired View Controller:

import FCAlertView

Presenting an FCAlertView

let alert = FCAlertView()

alert.showAlert(inView: self,
                withTitle: "Alert Title",
                withSubtitle: "This is your alert's subtitle. Keep it short and concise. ๐Ÿ˜œ๐Ÿ‘Œ",
                withCustomImage: nil,
                withDoneButtonTitle: nil,
                andButtons: nil)

Base Customizations

  • Title (String?): You can leave the Title as nil or Give it a String.

  • Subtitle (String): FCAlertView always requires a subtitle, even if you want just a few words, add it here instead of the title (then leave the title as nil). Take a look at Screenshot 2 for an example.

  • CustomImage (UIImage?): You can leave this image as nil or Give it a UIImage which will show at the top of the alert. Take a look at Screenshot 4 for an example.

  • DoneButtonTitle (String?): You can leave this as nil to show "Ok" as the dismiss button for the AlertView, or Give it an String.

  • Buttons ([String]?): If you want to add buttons to your alert, simply add an array of 1 or 2 button titles as String here, anything more will be ignored as 2 is the max custom buttons you can add (aside from the done button). Read more about buttons and actions further down.

Extra Customizations

This section includes all the tiny details that you can customize your alert with, which makes FCAlertView very customizable. Or leave it as is and enjoy the simplicity.

Color Scheme

By default, FCAlertView doesn't include a color scheme, much like UIAlertView, but you can add one by adding this line:

alert.colorScheme = UIColor(red: 150/255, green: 150/255, blue: 150/255, alpha: 1)

FCAlertView also comes with a set of pre-made colors that you can use:

alt text

Simply choose the color you'd like to use for your AlertView, and add:

alert.colorScheme = UIColor.flatBlue // Replace "Blue" with your preferred color from the image above
alert.colorScheme = .flatBlue // Alternative

Title and Subtitle Colors

Change Title Color by Adding one of:
alert.titleColor = UIColor.flatPurple
alert.titleColor = .flatPurple
Change SubTitle Color by Adding one of
alert.subTitleColor = UIColor.flatBlue
alert.subTitleColor = .flatBlue

AlertView Rounded Corners

Change the Rounding of the FCAlertView's corners as desired using:

alert.cornerRadius = 4 // Replace 4 with your desired corner radius amount (Set to 0.1 if you don't want rounding)

Alert Types

FCAlertView comes with 3 pre-designed custom alert types. Success, Caution, or Warning, simply add the type while initializing the FCAlertView.

let alert = FCAlertView(type: .success)
let alert = FCAlertView(type: .caution)
let alert = FCAlertView(type: .warning)

Dismissing FCAlertView

There are multiple ways you can dismiss an FCAlertView

Close on Outside Touch

When the user taps anywhere outside the alert, you can dismiss it by adding this line:

alert.dismissOnOutsideTouch = true
Auto-Close the Alert

Dismiss the AlertView when a certain time has elapsed after the AlertView is presented, by adding this line:

alert.autoHideSeconds = 5 // Replace 5 with the number of Seconds you'd like the view to appear for before dismissing itself
Done Button or Any Custom Buttons

All Buttons including the Done/Dismiss Button will make the FCAlertView dismiss.

Dismissing it yourself

If you'd like to dismiss the AlertView yourself, simply add the following line to where you need it:


Hiding Done/Dismiss Button

If you'd like to have no buttons on your AlertView (to simply display a notification or approval of something) or you want all your buttons to be a custom one which you've added yourself. Simply hide the Done buttons by adding this line:

alert.hideDoneButton = true

Hiding All Buttons

If you'd like to simply hide all buttons from your alert, you can do so by adding this line:

alert.hideAllButtons = true

Button Actions

To add actions to your buttons, you have to first delegate your FCAlertView with your view, and then add a helper method which will detect button touches. Here's how you can add an alert with buttons and perform actions:

First add the FCAlertViewDelegate protocol to your View Controller as such:

import UIKit
import FCAlertView

class ViewController : FCAlertViewDelegate {...}

Now add your FCAlertView with Buttons where you need to present it:

let alert = FCAlertView();

alert.delegate = self

alert.showAlert(inView: self,
             withTitle:"Alert Title",
          withSubtitle:"This is your alert's subtitle. Keep it short and concise. ๐Ÿ˜œ๐Ÿ‘Œ",
            andButtons:["Button 1", "Button 2"]) // Set your button titles here

After adding your FCAlertView, you can detect button touches by adding this method to your class:

func alertView(alertView: FCAlertView, clickedButtonIndex index: Int, buttonTitle title: String) {

    if title == "Button 1" {
        // Perform Action for Button 1
    }else if title == "Button 2"{
        // Perform Action for Button 2
Done Button Method

If you'd also like to detect button touch for the Done/Dismiss button, simply add this method to your class:

func FCAlertDoneButtonClicked(alertView: FCAlertView){
    // Done Button was Pressed, Perform the Action you'd like here.

Other Helper Methods

Make sure to add the FCAlertViewDelegate protocol to your View Controller as such:

import UIKit
import FCAlertView

class ViewController: FCAlertViewDelegate {...}

and setting the delegate of your FCAlertView, as such:

let alert = FCAlertView()
alert.delegate = self

Detect when FCAlertView has been dismissed

func FCAlertViewDismissed(alertView: FCAlertView){
    // Your FCAlertView was Dismissed, Perform the Action you'd like here.

Detect when FCAlertView is about to present

func FCAlertViewWillAppear(alertView: FCAlertView){
    // Your FCAlertView will be Presented, Perform the Action you'd like here.

About FCAlertView

FCAlertView is a fully customizable and beautifully designed AlertView. I designed FCAlertView beacuse I've always wanted to have access to change the different attributes of the default UIAlertView. Design wise, FCAlertView is similar looking to the default AlertView, however, as you start customizing it for your specific need, you realize it can do a lot more while looking flat and sharp.

FCAlertView lets you do things such as specify the number of buttons, the color scheme of the view, adding a small image to it, hide the view after a certain time, and more. A full description of how to customize FCAlertView to fit your alert can be found on http://github.com/nimati/FCAlertView.

The Vision for FC Libraries

My goal is to create a set of different libraries, each targetting a certain UI element of iOS, with the goal to improve the design and add more customizations. As such, FCAlertView is a more Flat/Customizable AlertView. With this mindset, I'd like to create more FC libraries, such as FCActionSheet, FCNotification (for quick, in app alerts), FCGuideView (for guiding your users around your app). If you also have a suggestion for an FC Library, please send it here.

Ultimately, FC Libraries is here to improve the look and feel of your app for your end users. So all improvements and suggestions are welcome.

Cheers ๐Ÿป
