Instead the label styles the new string using the font, textColor, and other style-related properties of the class. 38 | - **attributedText** Assigning a new value to this property also replaces the value of the text property with the same string data, albeit without any formatting information. In addition, assigning a new a value updates the values in the font, textColor, and other style-related properties so that they reflect the style information starting at location 0 in the attributed string. 39 | - **numberOfLines** This property controls the maximum number of lines to use in order to fit the label’s text into its bounding rectangle. The default value for this property is 0 which means using as many lines as needed（By now found a bug with Text Kit，numberOfLines will not work when lineBreakMode set to NSLineBreakByCharWrapping) 40 | 41 | 42 | 43 | Here gives an example of creating a SwiftyLabel： 44 | 45 | 46 | ```objc 47 | let label = SwiftyLabel(frame: CGRectMake(0, 0, 300, 400)) 48 | label.center = self.view.center 49 | label.delegate = self 50 | label.backgroundColor = UIColor(red: 243/255.0, green: 1, blue: 236/255.0, alpha: 1) 51 | label.text = "Swift is a powerful and intuitive programming language for iOS, OS X, tvOS, and watchOS. https://developer.apple.com/swift/resources/ . Writing Swift code is interactive and fun, the syntax is concise yet expressive, and apps run lightning-fast. Swift is ready for your next project — or addition into your current app — because Swift code works side-by-side with Objective-C. " 52 | label.textContainerInset = UIEdgeInsetsMake(6, 6, 6, 6) 53 | label.font = UIFont.systemFontOfSize(14) 54 | label.textColor = UIColor.blackColor() 55 | label.firstLineHeadIndent = 24 56 | label.drawsTextAsynchronously = true 57 | ``` 58 | 59 | #### Link 60 | The **Link** Attribute convert a range of text to clickable item. 61 | The **SwiftyTextLink** class is a model class designed to describe the link style and infomation. 62 | - **attributes**: Link attributes for the target text 63 | - **highlightedAttributes**: When highlighted, set the highlightedAttributes to the target text 64 | - **highlightedMaskRadius**, **highlightedMaskColor**: Stylish for mask when highlighted 65 | - **URL** ,**date**,**timeZone**,**phoneNumber**,**addressComponents**: These properties used for specialized link such as URL links, phoneNumber links 66 | 67 | Example： 68 | 69 | ```objc 70 | let link = SwiftyTextLink() 71 | link.URL = NSURL(string: "https://developer.apple.com/swift/") 72 | link.attributes = [NSForegroundColorAttributeName:UIColor(red: 0, green: 122/255.0, blue: 1.0, alpha: 1.0),NSUnderlineStyleAttributeName:NSUnderlineStyle.StyleSingle.rawValue] 73 | label.textStorage.setLink(link, range: NSMakeRange(0, 5)) 74 | ``` 75 | 76 | 77 | #### TextDetector 78 | 79 | The properties of **TBTextDetector** class: 80 | 81 | - **name**: The name of the detector 82 | - **linkable**: Should make the matched text to be clickable 83 | - **regularExpression**: The instance of NSRegularExpression class or subclass 84 | - **attributes**: Text attributes for matched text 85 | - **highlightedAttributes**: for the link attribute when linable is YES 86 | - **replacementBlock**: When **attributes** is not statisfy the requirements use this block to return the attributed text for replacement 87 | 88 | Example: 89 | 90 | ```objc 91 | let detector = SwiftyTextDetector.detectorWithType([.URL,.Address]) 92 | if detector != nil { 93 | label.addTextDetector(detector!) 94 | } 95 | ``` 96 | 97 | #### Attachment 98 | SwiftyTextAttachment makes some enhancements to vertical alignment and attachment type. With SwiftyTextAttachment you can treat a view as attachement. 99 | 100 | Example: 101 | 102 | ```objc 103 | let imageAttachment = SwiftyTextAttachment() 104 | imageAttachment.image = UIImage(named: "logo") 105 | imageAttachment.attachmentTextVerticalAlignment = .Top 106 | label.textStorage.insertAttachment(imageAttachment, atIndex: label.textStorage.length) 107 | 108 | let sliderAttachment = SwiftyTextAttachment() 109 | let slider = UISlider() 110 | sliderAttachment.contentView = slider; 111 | sliderAttachment.contentViewPadding = 3.0 112 | sliderAttachment.attachmentTextVerticalAlignment = .Center 113 | label.textStorage.insertAttachment(sliderAttachment, atIndex: 8) 114 | ``` 115 | 116 | The screenshot of the demo: 117 | 118 | 119 | 120 | #### Other Text Kit Features 121 | Other features of Text Kit can be achieved by NSTextStorage，NSLayoutManager，and NSTextContainer through properties of SwiftyLabel. 122 | 123 | ### Licenese 124 | SwiftyText is released under the MIT license.

Writing Swift code is interactive and fun, the syntax is concise yet expressive, and apps run lightning-fast. Swift is ready for your next project — or addition into your current app — because Swift code works side-by-side with Objective-C. " 83 | label.textContainerInset = UIEdgeInsetsMake(6, 6, 6, 6) 84 | label.font = UIFont.systemFontOfSize(14) 85 | label.textColor = UIColor.blackColor() 86 | label.firstLineHeadIndent = 24 87 | label.drawsTextAsynchronously = true 88 | ``` 89 | 90 | #### Link 91 | 这里的链接指的是文本中可以点击的内容。 92 | 链接属性在SwiftyText中使用 SwiftyTextLink来表示,SwiftyTextLink中包含如下的一些属性: 93 | - attributes 设置链接属性对应的文本的式样，使用标准的NSAttributedString的attributes 94 | - highlightedAttributes 点击高亮时 对应文本的样式属性，非高亮的时候会恢复到高亮之前的样式 95 | - highlightedMaskRadius，highlightedMaskColor 分别设置点击时 文本上的蒙层边角半径以及颜色 96 | - URL,date,timeZone,phoneNumber,addressComponents 这些是可能出现的常见的链接类型的相关值，如果不是这些特定链接，可以使用userInfo自己进行设置 97 | 98 | 代码示例： 99 | 100 | ```objc 101 | let link = SwiftyTextLink() 102 | link.URL = NSURL(string: "https://developer.apple.com/swift/") 103 | link.attributes = [NSForegroundColorAttributeName:UIColor(red: 0, green: 122/255.0, blue: 1.0, alpha: 1.0),NSUnderlineStyleAttributeName:NSUnderlineStyle.StyleSingle.rawValue] 104 | label.setLink(link, range: NSMakeRange(0, 5)) 105 | ``` 106 | 107 | 108 | #### TextParser 109 | 有很多时候我们需要对特定的模式的文本做特殊处理，诸如文本替换，或者特定的文本设置特定的属性，诸如颜色，字体等，这个时候我们便可以通过实现SwiftyTextParser protocol来实现自己的Text Parser，设置到SwiftyLabel中。Text Parser存在的好处在于处理逻辑的复用。 110 | 在SwiftyText中定义了一种叫做Detector的特殊Text Parser，可以通过设置正则以及对应的属性的方式来创建一个Parser。 111 | 还有一个特殊的Text Parser叫做 SwiftyTextSuperParser，它其实就是一个parser container， 是一个Text Parser的容器，这样就可以将多个 Text Parser合并成一个。 112 | 113 | 下面主要讲解下Detector 114 | - name detector的名字 115 | - linkable 是否是链接，如果是链接的话会对匹配的文本设置上Link属性，支持点击, 你还可以通过linkGestures来设置链接支持的手势 116 | - regularExpression 匹配的模式，类型为NSRegularExpression的实例或者其子类的对象 117 | - attributes 匹配的文本需要设置的属性，比如特定颜色，字体，下划线等 118 | - highlightedAttributes 当linkable为YES时，此属性用来决定匹配的文本的点击时的高亮属性 119 | - replacementBlock 当匹配的文本的属性的设置比较复杂的时候，没法通过简单的attributes来实现的时候，可以通过此block返回替换的attributedText 120 | 121 | ```objc 122 | let detector = SwiftyTextDetector.detectorWithType([.URL,.Address]) 123 | if detector != nil { 124 | label.parser = detector 125 | } 126 | ``` 127 | 128 | #### Attachment 129 | SwiftyTextAttachment在NSTextAttachment上做了增强，同时支持基于图片以及基于UIView的Attachment。 130 | 图片，UIView类型的附件都支持和文本在纵向上的各种对齐方式:靠顶对齐，居中，靠底对齐，缩放以适配文本高度，都支持通过设置padding来控制前后的padding。 131 | 图片Attachment还支持通过设置imageSize来控制图片的大小（当垂直对齐为 靠顶对齐，居中，靠底对齐时起作用） 132 | 133 | 134 | ```objc 135 | let imageAttachment = SwiftyTextAttachment() 136 | imageAttachment.image = UIImage(named: "logo") 137 | imageAttachment.attachmentTextVerticalAlignment = .Top 138 | label.insertAttachment(imageAttachment, atIndex: label.textStorage.length) 139 | 140 | let sliderAttachment = SwiftyTextAttachment() 141 | let slider = UISlider() 142 | sliderAttachment.contentView = slider; 143 | sliderAttachment.padding = 3.0 144 | sliderAttachment.attachmentTextVerticalAlignment = .Center 145 | label.insertAttachment(sliderAttachment, atIndex: 8) 146 | ``` 147 | 148 | 下图为demo的效果截图： 149 | 150 | 151 | 152 | #### 其余Text Kit的特性 153 | 其余的Text Kit的特性比如exclusionPaths，可以通过SwiftyLabel的exclusionPaths的属性进行设置。 154 | 155 | ### 许可证 156 | SwiftyText 基于 MIT license进行开源。 具体详情请查看根目录下的LICENSE文件。 157 | -------------------------------------------------------------------------------- /SwiftyText.podspec: -------------------------------------------------------------------------------- 1 | Pod::Spec.new do |s| 2 | s.name = 'SwiftyText' 3 | s.version = '0.0.3' 4 | s.license = 'MIT' 5 | s.summary = 'SwiftyText in Swift based on Text Kit' 6 | s.homepage = 'https://github.com/kejinlu/SwiftyText' 7 | s.social_media_url = 'http://weibo.com/kejinlu' 8 | s.authors = { 'Luke' => 'kejinlu@gmail.com' } 9 | s.source = { :git => 'https://github.com/kejinlu/SwiftyText.git', :tag => s.version } 10 | 11 | s.ios.deployment_target = '8.0' 12 | 13 | s.source_files = 'SwiftyText/**/*.swift' 14 | 15 | s.requires_arc = true 16 | end -------------------------------------------------------------------------------- /SwiftyText.xcodeproj/project.pbxproj: -------------------------------------------------------------------------------- 1 | // !$*UTF8*$! 2 | { 3 | archiveVersion = 1;
