iOS UIWebview加载本地设备HTML文件路径

Question

我正在开发一个iOS应用程序,我想在其中加载HTML文件UIWebView,我的html文件路径如下所示,

iPhone HTML文件路径:

/var/mobile/Applications/65A8E000-21A6-429E-90A0-6BF03BAB3EA5/SarkBuilderApp.app/SarkBuilerHtmlFile_new.html

我想加载这个iPhone设备的HTML文件路径UIWebView.

我怎样才能做到这一点？

非常感谢您的快速回答.让我解释一下我的基本要求,我正在开发一个iOS应用程序,其中我的要求是填充屏幕上的某些字段并生成.pdf文件.

为此,我采用了一个预先定义的HTML表单,之后我更新了.html文件并通过以下代码保存:

NSString *fileName = @"new_file_htmlfile.html";
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *html_file_name_location = [documentsDirectory stringByAppendingPathComponent:fileName];

NSError *error;

// Write the file
[data writeToFile:html_file_name_location atomically:YES
        encoding:NSUTF8StringEncoding error:&error];

通过这样做,我已经生成了新的HTML文件,我已经从代码中读取了文件路径.iPhone设备路径是:

/var/mobile/Applications/65A8E000-21A6-429E-90A0-6BF03BAB3EA5/SarkBuilderApp.app/SarkBuilerHtmlFile_new.html

iPhone模拟器路径是:

/Users/rightwaysolution/Library/Application Support/iPhone Simulator/6.1/Applications/20748991-EE5C-44FE-ACFF-D93542FCF95B/Documents/new_file_htmlfile.html

现在我正在尝试在我的UIWebView上加载iPhone设备HTML文件,以便我可以将其转换为.pdf.

你能告诉我如何访问该文件吗？

Answer 1

使用此代码来实现您想要的

NSString *htmlFile = [[NSBundle mainBundle] pathForResource:@"SarkBuilerHtmlFile_new" ofType:@"html"];
NSString* htmlString = [NSString stringWithContentsOfFile:htmlFile encoding:NSUTF8StringEncoding error:nil];
[webView loadHTMLString:htmlString baseURL:nil];

但为此,请确保您的html文件必须位于xcode中的app文件夹中

编辑: -

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"txtFile.txt"];
NSString *content = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:NULL];

NSString* htmlString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
[webView loadHTMLString:htmlString baseURL:nil];

要么

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"txtFile.txt"];
NSString *content = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:NULL];

NSString* htmlString = [NSString stringWithContentsOfFile:content encoding:NSUTF8StringEncoding error:nil];
[webView loadHTMLString:htmlString baseURL:nil];
