显示图片请调用:
10 | `+ initWithView:viewSize:lineAlignment:configure:`或者
11 | `+ insertViewAtAttrString:view:viewSize:atIndex:lineAlignment:configure:`方法初始化`NSAttributedString`后显示 12 | 5. `extendsLinkTouchArea`设置是否扩大链点点击识别范围 13 | 6. `shadowRadius`设置文本阴影模糊半径 14 | 7. `textInsets` 设置文本内边距 15 | 8. `verticalAlignment` 设置垂直方向的文本对齐方式。注意与显示图片时候的`imagelineAlignment`作区分，`self.verticalAlignment`对应的是整体文本在垂直方向的对齐方式，而`imagelineAlignment`只对图片所在行的垂直对齐方式有效 16 | 9. `delegate` 点击链点代理 17 | 10. `attributedTruncationToken`自定义截断字符，默认"...",只针对`self.lineBreakMode`的以下三种值有效，假如`attributedTruncationToken`=`***`，则：
18 | `NSLineBreakByTruncatingHead, // 头部截断: "***wxyz"`
19 | `NSLineBreakByTruncatingTail, // 中间截断: "abcd***"`

38 | 39 | ## CJLabel引用 40 | ##### 1. 直接导入 41 | 下载demo，将CJLabel文件夹导入项目，引用头文件 `#import "CJLabel.h"` 42 | ##### 2. CocoaPods安装 43 | ```ruby 44 | pod 'CJLabel' 45 | 46 | ``` 47 | 48 | ## 用法 49 | * 根据NSAttributedString计算CJLabel的size大小 50 | 51 | ```objective-c 52 | CGSize size = [CJLabel sizeWithAttributedString:str withConstraints:CGSizeMake(320, CGFLOAT_MAX) limitedToNumberOfLines:0]; 53 | ``` 54 | * 指定内边距以及限定行数计算CJLabel的size大小 55 | ```objective-c 56 | CGSize size = [CJLabel sizeWithAttributedString:str withConstraints:CGSizeMake(320, CGFLOAT_MAX) limitedToNumberOfLines:0 textInsets:3]; 57 | ``` 58 | 59 | * 设置富文本展示 60 |

188 | `+ initWithAttributedString:strIdentifier:configure:`
189 | 190 | * ***V2.1.2***
