如何在UIWebview中保存本地加载的HTML文件 [英] How to save a locally loaded HTML file in UIWebview

问题描述

我正在使用UIWebView编写一个富文本编辑器。为此，我使用一个模板文件作为启动器。

I am writing a rich text editor using UIWebView. To do this, I used a template file for a starter.

然后当用户完成编辑但尚未发布时，我想将当前内容保存为备份html文件，以防应用程序损坏。

Then when user finishes editing but has not published yet, I would like to save the current content into a back-up html file in case app corrupts.

我如何做？

Here you go... buddy

    NSFileHandle *file;
    NSMutableData *data;

    const char *bytestring = "black dog";//In your case html string here

    data = [NSMutableData dataWithBytes:bytestring length:strlen(bytestring)];
    NSString *path = //Path to your html file
     if ([filemgr fileExistsAtPath:path] == YES){
    NSLog (@"File exists");
file = [NSFileHandle fileHandleForUpdatingAtPath:path];

        if (file == nil)
                NSLog(@"Failed to open file");

        [file writeData: data];

        [file closeFile];
}
      else
    NSLog (@"File not found");
