如何对UILabel文本进行右对齐？

感谢

Answer 1

myLabel.textAlignment = UITextAlignmentRight;

iOS Developer Library是一个很好的资源。

Answer 2

您应该将文本对齐设置为对齐并将属性字符串基本书写方向设置为RightToLeft：

# chmod -R 777 /opt/apache-tomcat-8.0.23

Answer 3

上述方法已被弃用。新方法调用是：

label.textAlignment = NSTextAlignmentRight;

Answer 4

这是：如果需要应用完全证明，请注意firstLineIndent不应为零。

NSMutableParagraphStyle* paragraph = [[NSMutableParagraphStyle alloc] init];
paragraph.alignment = NSTextAlignmentJustified;
paragraph.baseWritingDirection = NSWritingDirectionRightToLeft;
paragraph.firstLineHeadIndent = 1.0;
NSDictionary* attributes = @{
                             NSForegroundColorAttributeName: [UIColor colorWithRed:0.2 green:0.239 blue:0.451 alpha:1],NSParagraphStyleAttributeName: paragraph};
NSString* txt = @"your long text";
NSAttributedString* aString = [[NSAttributedString alloc] initWithString: txt attributes: attributes];

Answer 5

它可以通过界面构建器。或 label.textAlignment = UITextAlignmentRight;

Answer 6

您可以将以下扩展程序用于Swift 5：

extension UILabel {
   func setJustifiedRight(_ title : String?) {
      if let desc = title {
           let text: NSMutableAttributedString = NSMutableAttributedString(string: desc)
           let paragraphStyle: NSMutableParagraphStyle = NSParagraphStyle.default.mutableCopy() as! NSMutableParagraphStyle
           paragraphStyle.alignment = NSTextAlignment.justified
           paragraphStyle.lineBreakMode = NSLineBreakMode.byWordWrapping
           paragraphStyle.baseWritingDirection = NSWritingDirection.rightToLeft
           text.addAttribute(NSAttributedString.Key.paragraphStyle, value: paragraphStyle, range: NSMakeRange(0, text.length))
           self.attributedText = text
       }
    }
}

并像这样简单地将文本设置为标签

self.YourLabel.setJustifiedRight("your texts")
