SCLAlertView para Swift 4.2
SCLAlertView
Animated Alert View written in Swift 4.2, which can be used as a UIAlertView
or UIAlertController
replacement. Since UIAlertView
is deprecated and UIAlertController
only works on iOS 8.x or above, if you have a Swift project where you want to support iOS 7.x too, SCLAlertView is an ideal substitution.
Easy to use
Get Started
// Get started
SCLAlertView().showInfo("Important info", subTitle: "You are great")
Updating the alert view
let alertViewResponder: SCLAlertViewResponder = SCLAlertView().showSuccess("Hello World", subTitle: "This is a more descriptive text.")
// Upon displaying, change/close view
alertViewResponder.setTitle("New Title") // Rename title
alertViewResponder.setSubTitle("New description") // Rename subtitle
alertViewResponder.close() // Close view
Alternative alert types
SCLAlertView().showError("Hello Error", subTitle: "This is a more descriptive error text.") // Error
SCLAlertView().showNotice("Hello Notice", subTitle: "This is a more descriptive notice text.") // Notice
SCLAlertView().showWarning("Hello Warning", subTitle: "This is a more descriptive warning text.") // Warning
SCLAlertView().showInfo("Hello Info", subTitle: "This is a more descriptive info text.") // Info
SCLAlertView().showEdit("Hello Edit", subTitle: "This is a more descriptive info text.") // Edit
Raw call to showTitle()
SCLAlertView().showTitle(
"Congratulations", // Title of view
subTitle: "Operation successfully completed.", // String of view
duration: 2.0, // Duration to show before closing automatically, default: 0.0
completeText: "Done", // Optional button value, default: ""
style: .success, // Styles - see below.
colorStyle: 0xA429FF,
colorTextButton: 0xFFFFFF
)
Controls
Custom Appearance
// SCLAlertView.SCLAppearanc has more than 15 different properties to customize. See below.
let appearance = SCLAlertView.SCLAppearance(
kTitleFont: UIFont(name: "HelveticaNeue", size: 20)!,
kTextFont: UIFont(name: "HelveticaNeue", size: 14)!,
kButtonFont: UIFont(name: "HelveticaNeue-Bold", size: 14)!,
showCloseButton: false
)
let alert = SCLAlertView(appearance: appearance)
Add buttons
let alertView = SCLAlertView()
alertView.addButton("First Button", target:self, selector:Selector("firstButton"))
alertView.addButton("Second Button") {
print("Second button tapped")
}
alertView.showSuccess("Button View", subTitle: "This alert view has buttons")
Hide default close button
let appearance = SCLAlertView.SCLAppearance(
showCloseButton: false
)
let alertView = SCLAlertView(appearance: appearance)
alertView.showSuccess("No button", subTitle: "You will have hard times trying to close me")
Hide default close button & a duration to close the alert
let appearance = SCLAlertView.SCLAppearance(
showCloseButton: false
)
let alertView = SCLAlertView(appearance: appearance)
alertView.showWarning("No button", subTitle: "Just wait for 3 seconds and I will disappear", duration: 3)
Hide alert icon
let appearance = SCLAlertView.SCLAppearance(
showCircularIcon: false
)
let alertView = SCLAlertView(appearance: appearance)
alertView.showSuccess("No icon", subTitle: "This is a clean alert without Icon!")
Use a custom icon
let appearance = SCLAlertView.SCLAppearance(
showCircularIcon: true
)
let alertView = SCLAlertView(appearance: appearance)
let alertViewIcon = UIImage(named: "IconImage") //Replace the IconImage text with the image name
alertView.showInfo("Custom icon", subTitle: "This is a nice alert with a custom icon you choose", circleIconImage: alertViewIcon)
Add Text fields
// Add a text field
let alert = SCLAlertView()
let txt = alert.addTextField("Enter your name")
alert.addButton("Show Name") {
print("Text value: \(txt.text)")
}
alert.showEdit("Edit View", subTitle: "This alert view shows a text box")
Use a custom subview instead of a subtitle
// Example of using the view to add two text fields to the alert
// Create the subview
let appearance = SCLAlertView.SCLAppearance(
kTitleFont: UIFont(name: "HelveticaNeue", size: 20)!,
kTextFont: UIFont(name: "HelveticaNeue", size: 14)!,
kButtonFont: UIFont(name: "HelveticaNeue-Bold", size: 14)!,
showCloseButton: false
)
// Initialize SCLAlertView using custom Appearance
let alert = SCLAlertView(appearance: appearance)
// Creat the subview
let subview = UIView(frame: CGRectMake(0,0,216,70))
let x = (subview.frame.width - 180) / 2
// Add textfield 1
let textfield1 = UITextField(frame: CGRectMake(x,10,180,25))
textfield1.layer.borderColor = UIColor.greenColor().CGColor
textfield1.layer.borderWidth = 1.5
textfield1.layer.cornerRadius = 5
textfield1.placeholder = "Username"
textfield1.textAlignment = NSTextAlignment.Center
subview.addSubview(textfield1)
// Add textfield 2
let textfield2 = UITextField(frame: CGRectMake(x,textfield1.frame.maxY + 10,180,25))
textfield2.secureTextEntry = true
textfield2.layer.borderColor = UIColor.blueColor().CGColor
textfield2.layer.borderWidth = 1.5
textfield2.layer.cornerRadius = 5
textfield1.layer.borderColor = UIColor.blueColor().CGColor
textfield2.placeholder = "Password"
textfield2.textAlignment = NSTextAlignment.Center
subview.addSubview(textfield2)
// Add the subview to the alert's UI property
alert.customSubview = subview
alert.addButton("Login") {
print("Logged in")
}
// Add Button with Duration Status and custom Colors
alert.addButton("Duration Button", backgroundColor: UIColor.brownColor(), textColor: UIColor.yellowColor(), showDurationStatus: true) {
print("Duration Button tapped")
}
alert.showInfo("Login", subTitle: "", duration: 10)

Collaboration
I tried to build an easy to use API, while beeing flexible enough for multiple variations, but I’m sure there are ways of improving and adding more features, so feel free to collaborate with ideas, issues and/or pull requests.
