如何在ios objective-c中使用NSAttributedString在多行标签中添加背景行

概述我想在 objective-c中使用NSAttributedString在多行标签中添加背景线,如下图所示 我使用以下代码 [yourView.layer setBorderWidth:5.0];[yourView.layer setBorderColor:[[UIColor colorWithPatternImage:[UIImage imageNamed:@"DotedImage.png"] 我想在 objective-c中使用NSAttributedString在多行标签中添加背景线,如下图所示

我使用以下代码

[yourVIEw.layer setborderWIDth:5.0];[yourVIEw.layer setbordercolor:[[UIcolor colorWithPatternImage:[UIImage imagenamed:@"DotedImage.png"]] CGcolor]];///just add image name and create image with dashed or doted drawing and add here

但它没有完美的工作,我想实现适当的方法,我怎么能实现这一点.使用这些也不合适Link1,Link2,Link3,Link4

我能够使用以下代码解决

NSAttributedString * Title =            [[NSAttributedString alloc] initWithString:@"I implement My test in here"                                            attributes:@{NsstrikethroughStyleAttributename:@(NSUnderlinestyleSingle)}];            [ self.vIEwOrderCell.labelitem setAttributedText:Title];

解决方法 你可能意味着Strike,iOS 6.0和更高版本,UILabel支持NSAttributedString和NSMutableAttributedString

使用NSAttributedString时

NSAttributedString * Title =    [[NSAttributedString alloc] initWithString:@"Your String here"                                    attributes:@{NsstrikethroughStyleAttributename:@(NSUnderlinestyleSingle)}];[label setAttributedText:Title];

定义：

/**  * Returns an NSAttributedString object initialized with a given string and attributes. * *  @param str : The string for the new attributed string. *  @param attrs : The attributes for the new attributed string. For information *  about where to find the attribute keys you can include in this dictionary,*  see the overvIEw section of this document. * *  @return     Returns an NSAttributedString object initialized with the characters of aString and the attributes of attributes. The returned object might be different from the original receiver. */- (instancetype)initWithString:(Nsstring *)str attributes:(NSDictionary *)attrs;

使用NSMutableAttributedString时

NSMutableAttributedString *attributeString = [[NSMutableAttributedString alloc] initWithString:@"Your String here"];[attributeString addAttribute:NsstrikethroughStyleAttributename                        value:@2                        range:NSMakeRange(0,[attributeString length])];

定义：

/** * *  @param name : A string specifying the attribute name. Attribute keys can be *  supplIEd by another framework or can be custom ones you define. For *  information about where to find the system-supplIEd attribute keys,see the *  overvIEw section in NSAttributedString Class Reference.   * *  @param value : The  attribute value associated with name. * *  @param arange : The range of characters *  to which the specifIEd attribute/value pair applIEs. */- (voID)addAttribute:(Nsstring *)name value:(ID)value range:(NSRange)arange;

然后

yourLabel.attributedText = attributeString;
