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操作
@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];
}
