IOS中的正交连字词

Question

是否有正字连字词的方法？

像这样的东西:

NSStiring *string = @"In June 2010 at the World Wide Developers Conference, Apple announced version 4 of Xcode during the Developer Tools State of the Union address.";
UILabel *label = [[UILabel alloc] init];
label.text = string;

如果框架UILabel将变窄,请进入下一步:

Answer 1

将NSAttributedString与NSParagraphStyle一起使用hyphenationFactor,其中a 为1.

目标-C

NSString *string = @"In June 2010 at the World Wide Developers Conference, Apple announced version 4 of Xcode during the Developer Tools State of the Union address.";
NSMutableParagraphStyle * paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.hyphenationFactor = 1.0;
NSMutableAttributedString * attributedString = [[NSMutableAttributedString alloc] initWithString:string];
UILabel *label = [[UILabel alloc] init];
label.attributedText = attributedString;

let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.hyphenationFactor = 1.0
let attributedString = NSMutableAttributedString(string: "Your String", attributes: [NSAttributedStringKey.paragraphStyle:paragraphStyle])
self.yourLabel.attributedText = attributedString

paragraphStyle.hyphenationFactor = 1.0
let attributedString = NSMutableAttributedString(string: "Your String", attributes: [NSParagraphStyleAttributeName:paragraphStyle])
self.yourLabel.attributedText = attributedString
