macOS Float Label Pattern Text Field

A macOS Cocoa single-line NSTextField/NSSecureTextField that implements the Float Label Pattern. You can read about the float pattern here.

I was curious as to whether this pattern would work for a Mac program. I wanted this to be a basic drop-in for an existing text field, using the NSTextField placeholderString value as the floating label title.

Add https://github.com/dagronf/DSFFloatLabelledTextControl to your project.

Add pod 'DSFFloatLabelledTextControl', :git => 'https://github.com/dagronf/DSFFloatLabelledTextControl' to your podfile.

• Drop in a new Text Field into your canvas and set its class to DSFFloatLabelledTextField or DSFFloatLabelledSecureTextControl depending on whether you need a secure field
• Set the size and style of your primary font as you would a regular text field
• Set the size of the secondary font via the attributes inspector for the control

let field = DSFFloatLabelledTextField()
field.placeholderString = "Dynamic Created"
field.font = NSFont.systemFont(ofSize: 16)
parentView.addSubview(field)
		
/// Setup autolayout constraints etc.

These controls inherit from NSTextField, so all NSTextField functionalities (like cocoa binding and Interface Builder settings) are available. If you can use an NSTextField, you can use this control.

• placeholderTextSize - the size of the text used in the floating label (in pt)
• placeholderSpacing - the distance between the text field text and the floating label (in px)

You can specify a delegate (floatLabelDelegate), either programatically or via Interface Builder, to receive additional information regarding the actions of the control.

• Pattern devised by Matt D. Smith
• Read about the pattern here
• UITextField implementation

• 2.0.0: Moved secure text field into separate class (fixing security warnings in modern Xcode)
• 1.8.0: Added secure text field support, delegate support
