GRichLabel

A rich Label that supports selection, copying.

Features

• 1,基于coretext绘制文本.内部使用YYAsyncLayer提供异步绘制任务
• 2,支持选择/复制文本.
• 3,支持自定义表情排版
• 4,可自定义文本选择弹出menuView GMenuContoller
• 5,对于文本token 采用多模匹配算法. 详见GMatcherExpression.文本匹配效率比系统字符串匹配效率提高百倍.
• 6,功能以及代码还在更新完善中. 后期会支持更多功能.欢迎star.
• 7,支持文本在滚动视图中做文本滚动选择 （微信聊天气泡文本选择）

Usage

1

 GRichLabel *richLabel = [GRichLabel new];
richLabel.frame = CGRectMake(5, 0, self.view.frame.size.width-10, 500);
richLabel.text = @"xxxxxx";

2

{
self.tokens = @[@"@冯科",@"@王金yu",@"@巩柯",@"#郭天池#"];
GRichLabel *richLabel = [GRichLabel new];
richLabel.frame = CGRectMake(5, 0, self.view.frame.size.width-10, 500);
}
- (void)setRichText
{
__weak typeof(self) ws = self;
NSString* string =[selfcontent1];
__block NSMutableArray *tokens = [NSMutableArrayarray];
[self.tokens enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
if (!obj) *stop = NO;
GAttributedToken * token = [GAttributedToken attributedTextToken:obj];
token.tokenClickBlock = ^(GAttributedToken *token) {
[ws gotoVC:token.textToken];
};
[tokens addObject:token];
}];
GAttributedToken *regex = [GAttributedToken new];
regex.regexToken = Phone;
regex.tokenClickBlock = ^(GAttributedToken *token) {
};
GAttributedStringLayout *layout = [GAttributedStringLayout attributedLayout:string];
layout.tokenPatternConfigs = tokens.copy;
layout.regexPatternConifgs = @[regex];
layout.textAlignment = kCTTextAlignmentJustified;
layout.linespace = 1;
layout.lineIndent = 2;
layout.font = [UIFont systemFontOfSize:14];
NSMutableAttributedString * truncation = [[NSMutableAttributedStringalloc] initWithString:@"...全文"];
layout.truncationToken = truncation;
GDrawTextBuilder * builder = [GAttributedStringFactory createDrawTextBuilderWithLayout:layout boundSize:self.richLabel.frame.size];
self.richLabel.textBuilder = builder;
}

Installation

• 手动添加

1. git clone https://github.com/GIKICoder/GRichLabel.git
2. 选择GRichLabel文件夹.拖入项目中.
3. GRichLabel 依赖 GMenuController https://github.com/GIKICoder/GMenuController, YYAsyncLayer https://github.com/ibireme/YYAsyncLayer 这2个库. 可以使用pod添加. 也可下载手动添加到项目

update Info

• 29/10/2017 代码重构.处理耦合逻辑.简化代码.重新整理NSAttributedString分类(参考NSAttributedString+YYText).使GRichLabel具有更强大的文本处理能力.
• 06/12/2017 增加kGAttributeTokenReplaceStringName. 支持自定义表情 链接等字符串copy 处理.
• 19/04/2018 增加GMatherExpression 增加字符匹配模式.
• 27/08/2018 增加文本选择模式，在滚动视图下可支持滚动文本选择。
