96 | 97 | ### 讲解 98 | 99 | * `RZColorfulConferrer` 中 `paragraphStyle` 和 `shadow` 属于全局的设置，在block中任何位置都可设置 100 | * 文字和图片都可设置`paragraphStyle` 和 `shadow`，对齐方式是`paragraphStyle` 的`alignment`，设置后，当前行文字图片的全局样式将被此覆盖，即全局样式无效，不影响其他行。 101 | 102 | 103 | ### 基本的简单使用方法 104 | ```objc 105 | [cell.textLabel rz_colorfulConfer:^(RZColorfulConferrer * _Nonnull confer) { 106 | confer.paragraphStyle.paragraphSpacing(15); // 设置段落之间的行距 107 | 108 | confer.text(@"日常用处:(图片+标题+描述)\n").font(rzFont(17)).textColor([UIColor redColor]); 109 | 110 | confer.appendImage([UIImage imageNamed:@"test.jpg"]).bounds(CGRectMake(0, -2, 15, 15)); // 图片 111 | confer.text(@" 姓 名: ").font(rzFont(15)).textColor(RGBA(151, 151, 151, 11)); 112 | confer.text(@"rztime").font(rzFont(15)).textColor(RGBA(51, 51, 51, 1)); 113 | 114 | confer.text(@"\n"); 115 | confer.appendImage([UIImage imageNamed:@"test.jpg"]).bounds(CGRectMake(0, -2, 15, 15)); 116 | confer.text(@" 时 间: ").font(rzFont(15)).textColor(RGBA(151, 151, 151, 11)); 117 | confer.text([NSString stringWithFormat:@"%@", [NSDate new]]).font(rzFont(15)).textColor(RGBA(51, 51, 51, 1)); 118 | 119 | confer.text(@"\n"); 120 | confer.appendImage([UIImage imageNamed:@"test.jpg"]).bounds(CGRectMake(0, -2, 15, 15)); 121 | confer.text(@" 当次消费: ").font(rzFont(15)).textColor(RGBA(151, 151, 151, 11)); 122 | confer.text(@"￥").font(rzFont(15)).textColor(RGBA(51, 51, 51, 1)); 123 | confer.text(@"100").font(rzFont(15)).textColor(RGBA(251, 51, 51, 1)); 124 | confer.text(@"元").font(rzFont(15)).textColor(RGBA(51, 51, 51, 1)); 125 | }]; 126 | ``` 127 | 效果如下 128 |

129 | 130 |

131 | 132 | ### 段落样式、阴影（局部与全局统一的区别） 133 | 如果设置有局部样式，则全局样式无效 134 | ```objc 135 | [cell.textLabel rz_colorfulConfer:^(RZColorfulConferrer * _Nonnull confer) { 136 | confer.paragraphStyle.lineSpacing(5).paragraphSpacingBefore(5).alignment(NSTextAlignmentCenter); // 段落全局样式 137 | confer.shadow.color(RGBA(255, 0, 0, 0.3)).offset(CGSizeMake(1, 1)); // 阴影全局 138 | 139 | // 此部分显示全局样式的风格 （红色阴影，居中对齐，段落行距等） 140 | confer.appendImage([UIImage imageNamed:@"test.jpg"]).bounds(CGRectMake(0, -2, 15, 15)); 141 | confer.text(@" 姓名: ").font(rzFont(15)).textColor(RGBA(151, 151, 151, 11)); 142 | confer.text(@"rztime").font(rzFont(15)).textColor(RGBA(51, 51, 51, 1)); 143 | 144 | confer.text(@"\n"); 145 | confer.appendImage([UIImage imageNamed:@"test.jpg"]).bounds(CGRectMake(0, -2, 15, 15)); 146 | confer.text(@" 时间: ").font(rzFont(15)).textColor(RGBA(151, 151, 151, 11)); 147 | confer.text([NSString stringWithFormat:@"%@", [NSDate new]]).font(rzFont(15)).textColor(RGBA(51, 51, 51, 1)); 148 | 149 | // 此部分显示全局样式的风格 （居中对齐，段落行距等） 阴影将被局部覆盖（灰色） 150 | confer.text(@"\n地址: ").font(rzFont(15)).textColor(RGBA(151, 151, 151, 11)).paragraphStyle.paragraphSpacingBefore(20).and.shadow.color(GRAY(151)).offset(CGSizeMake(3, 3));; 151 | confer.text(@"成都-软件园").font(rzFont(15)).textColor(RGBA(51, 51, 51, 1)).shadow.color(GRAY(151)).offset(CGSizeMake(3, 3)); 152 | 153 | // 此部分段落样式被局部覆盖 阴影显示全局的 154 | confer.text(@"\n爱好: ").font(rzFont(15)).textColor(RGBA(151, 151, 151, 11)).paragraphStyle.paragraphSpacingBefore(20); 155 | confer.text(@"游山、").font(rzFont(15)).textColor(RGBA(151, 51, 51, 1)); 156 | confer.text(@"玩水、").font(rzFont(10)).textColor(RGBA(51, 151, 51, 1)); 157 | confer.text(@"听歌、").font(rzFont(18)).textColor(RGBA(51, 51, 151, 1)); 158 | confer.text(@"美食、").font(rzFont(17)).textColor(RGBA(51, 151, 51, 1)); 159 | confer.text(@"看电影、").font(rzFont(16)).textColor(RGBA(151, 51, 51, 1)); 160 | confer.text(@"撸代码、").font(rzFont(15)).textColor(RGBA(51, 151, 51, 1)); 161 | confer.text(@"等等\n\n").font(rzFont(15)).textColor(RGBA(251, 51, 51, 1)); 162 | }]; 163 | ``` 164 | 效果如下 165 |

166 | 167 |

168 | 169 | 通过url加载图片 170 | ```objc 171 | [cell.textLabel rz_colorfulConfer:^(RZColorfulConferrer * _Nonnull confer) { 172 | confer.appendImageByUrl(@"http://pic28.photophoto.cn/20130830/0005018667531249_b.jpg").bounds(CGRectMake(0, 0, 200, 0)).paragraphStyle.alignment(NSTextAlignmentLeft); // 宽或高为0时，即自动宽/高按照图片比例来 173 | }]; 174 | ``` 175 | 通过html源码加载文本 176 | ```objc 177 | [cell.textLabel rz_colorfulConfer:^(RZColorfulConferrer * _Nonnull confer) { 178 | NSString *resourcePath = [[NSBundle mainBundle] resourcePath]; 179 | NSString *filePath =[resourcePath stringByAppendingPathComponent:@"test.html"]; 180 | NSString *htmlstring=[[NSString alloc] initWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil]; 181 | confer.htmlText(htmlstring); 182 | }]; 183 | ``` 184 | 185 | 给UILabel添加富文本可点击功能 给文本添加tapActionByLable属性 186 | ```objc 187 | [_label rz_colorfulConfer:^(RZColorfulConferrer * _Nonnull confer) { 188 | confer.text(@"可点击的：").font([UIFont systemFontOfSize:17]).textColor(UIColor.blackColor); 189 | confer.text(@"文本").font([UIFont systemFontOfSize:17]).textColor(UIColor.redColor).tapActionByLable(@"1"); 190 | }]; 191 | [_label rz_tapAction:^(UILabel * _Nonnull label, NSString * _Nonnull tapActionId, NSRange range) { 192 | NSLog(@"%@", tapActionId); // print: 1 193 | }]; 194 | ``` 195 | 196 | 给UILabel添加超行之后的折叠、展开功能 197 | ```objc 198 | UILabel 199 | 200 | /// 设置富文本（超过行数后，自动追加“展开” “收起”） 201 | /// @param attr 原文 202 | /// @param line 最大显示行数 203 | /// @param width 最大显示宽度，这个宽度用于计算文本行 204 | /// @param fold 当前是否折叠 205 | /// @param allText 超过了行数之后，折叠状态显示的文本 如”展开“ 需要给文本设置NSTapActionByLabel属性 (tapActionByLable) 206 | /// @param foldText 超过行数之后，全部展开状态显示的文本 如”收起“ 需要给文本设置NSTapActionByLabel属性 (tapActionByLable) 207 | - (void)rz_setAttributedString:(NSAttributedString * _Nullable)attr maxLine:(NSInteger)line maxWidth:(CGFloat)width isFold:(BOOL)fold showAllText:(NSAttributedString *_Nullable)allText showFoldText:(NSAttributedString *_Nullable)foldText; 208 | ``` 209 | 210 | # 备注： 211 | * 多种属性使用名请参考对应的文件。 212 | * UILabel、UITextFile是同样的使用方法。 213 | * 在UILabel、UITextFiled上url点击方法无效。 214 | * 在UITextView中若要设置文本和图片的点击事件（即对文本和图片设置附带URL的属性），请先设置其editable = NO, 并实现代理。 215 | * 设置了URL属性的文本，内部自带蓝色和下划线，若要去掉，可设置 `textView.linkTextAttributes = @{};` 216 | 217 | ```objc 218 | // 实现下列方法 （二选一、或都可以实现，当都返回YES时，可能会打开safari浏览器） 219 | textView.rzDidTapTextView = ^BOOL(id _Nullable tapObj) { 220 | NSString *url = tapObj; 221 | if ([tapObj isKindOfClass:[NSURL class]]) { 222 | url = [(NSURL *)tapObj absoluteString]; 223 | } 224 | url = url.rz_decodedString; 225 | 226 | NSLog(@"rzDidTapTextView：tapObj:%@ \n如果url中包含了有中文,URL将会进行编码，所以请rz_decodedString解码之后查看:%@", tapObj, url); 227 | return NO; 228 | }; 229 | 230 | - (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange interaction:(UITextItemInteraction)interaction { 231 | NSLog(@"URL:%@", URL); 232 | // return NO;则不跳转，这里可以做一些基本判断在执行是否跳转浏览器打开url 233 | return YES; 234 | } 235 | ``` 236 | 237 | ## 注意 238 | 239 | * 尽管我已经在代码中已经处理过（弱）引用问题，但是在实际运用写入text时，还是请尽量检查避免循环引用 240 | 241 | 242 | ## 最后 243 | * 在使用过程中，如果您发现有什么问题，欢迎向我反馈，谢谢 244 | -------------------------------------------------------------------------------- /RZColorful/Classes/AttributeCore/RZColorfulAttribute.m: -------------------------------------------------------------------------------- 1 | // 2 | // RZAttribute.m 3 | // RZAttributedStringText 4 | // 5 | // Created by 乄若醉灬 on 2017/7/21. 6 | // Copyright © 2017年 rztime.
