행간 조절이 가능한 UITextView의 subclass (Swift 2.0)

텍스트 속성 조절 가능한 UITextView의 subclass : MYTextFrame예제.

initializeTextBox()의 파라메터에 적절한 값을 넣어 주면 굴러감.

import UIKit

class MYTextFrame: UITextView {

    

    var contentText = NSString()

    

    func initializeTextBox(pathOfTextFile: String, typeOfExtension: String, spaceOfLine: CGFloat, canScroll: Bool, canEdit: Bool){

        

        //Text path

        let filePath = NSBundle.mainBundle().pathForResource(pathOfTextFile, ofType: typeOfExtension)

        

        //Text file to string

        do {

            contentText = try NSString(contentsOfFile: filePath!, encoding: NSUTF8StringEncoding)

        } catch {

            contentText = "text is not found."

        }

                

        //Line Spacing

        let lineSpaceAmount = NSMutableParagraphStyle()

        lineSpaceAmount.lineSpacing = spaceOfLine

        self.attributedText = NSAttributedString(string: contentText as String, attributes: [NSParagraphStyleAttributeName:lineSpaceAmount])

        

        //Scrollable?

        self.scrollEnabled = canScroll

        //Editable?

        self.editable = canEdit

    }

    

}
