ioshtml转富文本设置字体字体失效

ioshtml转富文本设置字体字体失效:首先定义自己的标签格式

解析字符串，分别获得标签中文字的属性和内容

根据属性，创建NSAttributedString

例如：// [标签名称_粗细_字号_字体颜色_下划线_斜体_背景色_对其方式]

[custom_0_16_#004455_0_0_#000000_01]我是内容[/custom]

二、NSAttributedString 转 自定义标签

获得NSAttributedString数据

使用对应的方法，获取NSAttributedString中字符串的属性信息

根据属性信息，定义自己的自定义标签

例如：// 获取富文本中，每段字符串的属性信息

实现：1、首次图文混编，输出是html标签的字符串；

            2、将html标签的内容再次编辑；

创建编辑控制器

.h文件

@property (nonatomic,strong)NSString *inHtmlString

block是将编辑的内容返回上个页面 *** 作

@property (nonatomic, copy)void (^postBlock)(NSString *htmlString)

.m文件

JavaScriptCore/JavaScriptCore.h

WebKit/WebKit.h

实现WKWebView的代理及相册的代理（懒得弄。用的系统相册）

NSString*_htmlString//保存输出的富文本

    NSMutableArray*_imageArr//保存添加的图片

@property (nonatomic, strong) WKWebView *webView

加载写好的 .html文件 给个简易版本的即可

NSBundle *bundle = [NSBundle mainBundle]

    NSURL*indexFileURL = [bundleURLForResource:@"richTextEditor"withExtension:@"html"]

    [self.webView loadRequest:[NSURLRequest requestWithURL:indexFileURL]]

创建一个button 选择图片，给个点击事件

[btn1 addTarget:self action:@selector(addImage) forControlEvents:UIControlEventTouchUpInside]

创建一个button 保存html字符串，给个点击事件

[btn2 addTarget:self action:@selector(printHTML) forControlEvents:UIControlEventTouchUpInside]

- (void)printHTML{

    [self.webView evaluateJavaScript:@"document.getElementById('content').innerHTML" completionHandler:^(id _Nullable result, NSError * _Nullable error) {

        NSLog(@"html=%@",result)

        !self.postBlock?:self.postBlock(result)

        [self.navigationController popViewControllerAnimated:YES]

    }]

}

- (void)addImage{

    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init]

    imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary

    imagePickerController.delegate=self

    [self presentViewController:imagePickerController animated:YES completion:nil]

}

实现相册代理方法

#pragma mark - ImagePickerController Delegate

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

{

    UIImage * image = [info objectForKey:UIImagePickerControllerOriginalImage]

    NSData *data = UIImagePNGRepresentation(image)

    if(2*1024*1024>[datalength]) {

        data =UIImageJPEGRepresentation(image,0.6)

    }else{

    }

    UIImage*resultImage = [UIImageimageWithData:data]

    NSString *imagePath = [NSString stringWithFormat:@"%@", [info objectForKey:UIImagePickerControllerImageURL]]//本地图片路径

    [datawriteToFile:imagePathatomically:YES]

此处是将已添加的图片上传至你们的服务器

上传成功后执行

            NSString*url =服务器图片地址

            NSString*script = [NSStringstringWithFormat:@"window.insertImage('%@', '%@')", imagePath, url]

            NSDictionary*dic =@{@"url":url,@"image":image,@"name":imagePath}

            [_imageArraddObject:dic]

            [self.webViewevaluateJavaScript:scriptcompletionHandler:^(id_Nullableresult,NSError*_Nullableerror) {

            }]

            [self dismissViewControllerAnimated:YES completion:nil]

}
