# TYAttributedLabel v2.6
TYAttributedLabel 简单,强大的属性文本的控件(无需了解CoreText),支持图文混排显示,支持添加链接,image和UIView控件,支持自定义排版显示

**新的异步渲染[TYText](https://github.com/12207480/TYText)**:text asynchronous rendering by TextKit

**更新:**

详细的使用请看[LovePlayNews](https://github.com/12207480/LovePlayNews)项目

使用autolayout 如果需要自动推断高度,必须设置preferredMaxLayoutWidth

添加到CocoaPods

微博demo(建议真机调试) 下载地址:链接: http://pan.baidu.com/s/1sjnBWRj 密码: t7qn

v2.6 新增宽度自适应isWidthToFit,空心字设置strokeWidth,段落间距paragraphSpacing

v2.5 把label的一些操作移动textContainer,label只负责draw了。

v2.4 修复imge放大bug,新增imageAlignment 和 autolayout支持,以及相应的demo,感谢xinzhengzhang,nonstriater

v2.3 新增 做题demo,代码优化

v2.2 新增 TYImagecache类,新增 image URL 下载缓存,功能优化,改进

v2.1 添加 tableViewCell demo

v2.0 重构优化代码,性能提升,稳定(已在项目中使用), 分离出TYTextContainer ,可以提前生成,也可以生成attributedString,显著提升cell滑动场景流畅度,可以和微博一样流畅

v1.2 添加设置行数,修复bug,增强稳定性

v1.1 添加链接高亮效果,链接便利方法,长按手势代理,优化代码

## CocoaPods
```
pod 'TYAttributedLabel', '~> 2.6.2'
```

## Requirements
* Xcode 5 or higher
* Apple LLVM compiler
* iOS 6.0 or higher
* ARC

## Features
* 支持属性文本,图文混排显示,支持行间距 行间距 段落间距,设置行数,自适应高度,宽度
* 支持添加自定义文本属性
* 支持添加属性文本,自定义链接,新增高亮效果显示(文字和背景)
* 支持添加UIImage和UIView控件

## Demo
运行demo可以查看效果,而且在demo中,针对各种文本和图文的实现都有详细的用例,每个头文件中都有详细的用法注释,这里简单的介绍下用法

## Usage
### API Quickstart

* **Category And Protocol**

|Class | Function|
|--------|---------|
|NSMutableAttributedString (TY) |category提供便利color,font CharacterSpacing,UnderlineStyle,ParagraphStyle的属性添加,无需了解复杂的CoreText|
|TYTextStorageProtocol|自定义文本属性 遵守最基本的协议 即可 addTextStorage 添加进去|
|TYAppendTextStorageProtocol|自定义文本属性协议 遵守即可appendTextStorage 添加进去|
|TYLinkStorageProtocol|自定义文本链接属性 继承TYAppendTextStorageProtocol|
|TYDrawStorageProtocol|自定义显示内容协议 如 UIImage UIView|

下层协议继承上层的协议,如果觉得复杂,其实我已经实现了常用的自定义属性,拿来就可以用,或者继承,添加你想要的

* **Label And Storage**

|Class |Function |
|--------|---------|
|TYAttributedLabel|简单易用的属性文本,富文本的显示控件,
addTextStorage在已经设置文本的基础上添加属性,image或者view,
appendTextStorage(无需事先设置文本)直接添加属性,image或者view到最后|
|TYTextContainer|文本容器,可以提前生成,也可以生成attributedString,显著提升cell滚动流畅度|
|TYTextStorage|自定义文本属性,支持textColor,font,underLineStyle|
|TYLinkTextStorage|自定义链接属性,继承TYTextStorage,支持点击代理|
|TYDrawStorage|自定义显示内容属性,如UIImage,UIView,支持点击代理|
|TYImageStorage|自定义图片显示,继承TYDrawStorage|
|TYViewStorage|自定义UIView控件,继承TYDrawStorage|
|TYImageCache|image缓存类,支持URL请求|

如果需要更加详细的内容,请看各个头文件,有详细的注释

### Delegate

```objc

// 点击代理
- (void)attributedLabel:(TYAttributedLabel *)attributedLabel textStorageClicked:(id)textStorage atPoint:(CGPoint)point;

// 长按代理 有多个状态 begin, changes, end 都会调用,所以需要判断状态
- (void)attributedLabel:(TYAttributedLabel *)attributedLabel textStorageLongPressed:(id)textStorage onState:(UIGestureRecognizerState)state atPoint:(CGPoint)point;

```

### Examples

* **appendStorage demo**

```objc

TYAttributedLabel *label = [[TYAttributedLabel alloc]init];
[self.view addSubview:label];

// 文字间隙
label.characterSpacing = 2;
// 文本行间隙
label.linesSpacing = 6;

NSString *text = @"\t总有一天你将破蛹而出,成长得比人们期待的还要美丽。\n";
[label appendText:text];

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc]initWithString:text];
[attributedString addAttributeTextColor:[UIColor blueColor]];
[attributedString addAttributeFont:[UIFont systemFontOfSize:15]];
[label appendTextAttributedString:attributedString];

[label appendImageWithName:@"CYLoLi" size:CGSizeMake(CGRectGetWidth(label.frame), 180)];

UIImageView *imageView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"CYLoLi"]];
imageView.frame = CGRectMake(0, 0, CGRectGetWidth(label.frame), 180);
[label appendView:imageView];

[label setFrameWithOrign:CGPointMake(0,0) Width:CGRectGetWidth(self.view.frame)];

```
* **addStorage demo**

```objc

TYAttributedLabel *label = [[TYAttributedLabel alloc]initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.view.frame), 0)];
[self.view addSubview:label];

NSString *text = @"\t总有一天你将破蛹而出,成长得比人们期待的还要美丽。\n";
[label setText:text];

// 文字间隙
label.characterSpacing = 2;
// 文本行间隙
label.linesSpacing = 6;

textStorage = [[TYTextStorage alloc]init];
textStorage.range = [text rangeOfString:@"总有一天你将破蛹而出"];
textStorage.textColor = RGB(0, 155, 0, 1);
textStorage.font = [UIFont systemFontOfSize:18];
[label addTextStorage:textStorage];

[label addLinkWithLinkData:@"www.baidu.com" range:NSMakeRange(5, 8)];

[label addImageWithName:@"haha" range:NSMakeRange(2, 1)];

UIImageView *imageView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"CYLoLi"]];
imageView.frame = CGRectMake(0, 0, CGRectGetWidth(label.frame), 180);
[label addView:imageView range:NSMakeRange(16, 1)];

[label sizeToFit];

```

* **TextContainer demo**
```objc
NSString *text = @"\t总有一天你将破蛹而出,成长得比人们期待的还要美丽。\n";
TYTextContainer *textContainer = [[TYTextContainer alloc]init];
textContainer.text = text;
// 文字间隙
textContainer.characterSpacing = 2;
// 文本行间隙
textContainer.linesSpacing = 5;

textStorage = [[TYTextStorage alloc]init];
textStorage.range = [text rangeOfString:@"总有一天你将破蛹而出"];
textStorage.textColor = RGB(0, 155, 0, 1);
textStorage.font = [UIFont systemFontOfSize:18];
[textContainer addTextStorage:textStorage];

[textContainer addLinkWithLinkData:@"www.baidu.com" range:NSMakeRange(5, 8)];

[textContainer addImageWithName:@"haha" range:NSMakeRange(2, 1)];

UIImageView *imageView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"CYLoLi"]];
imageView.frame = CGRectMake(0, 0, CGRectGetWidth(label.frame), 180);
[textContainer addView:imageView range:NSMakeRange(16, 1)];

// 生成 textContainer 文本容器
[textContainer createTextContainerWithTextWidth:CGRectGetWidth(self.view.frame)];

TYAttributedLabel *label = [[TYAttributedLabel alloc]init];
label.textContainer = textContainer;

// 也可以 生成NSAttributedString 属性文本
//NSAttributedString *attString = [textContainer createAttributedString];
//label.attributedText = attString;

[label setFrameWithOrign:CGPointZero Width:CGRectGetWidth(self.view.frame)];
[self.view addSubView:label];
```
