UIWebView 不打开 ms word (doc) 和 ms excel (xls) 文件 [英] UIWebView does not open ms word (doc) and ms excel (xls) files

问题描述

我正在使用 XCode 3.2.5 iOS SDK 4.2 为 iPad 开发应用程序.此应用程序需要打开 PDF、DOC 和 XLS 文件并向用户预览.

I'm developing an application for iPad using XCode 3.2.5 iOS SDK 4.2. This application requires to open PDF, DOC and XLS files and preview them to the user.

我正在尝试使用 UIWebView 控件打开它们.只有 PDF 文件被正确打开.打开 DOC 或 XLS 时，我看到一个黑色的空白视图.这发生在模拟器和设备中.

I'm trying to open them with the UIWebView control. Only PDF files are being opened correctly. When opening DOC or XLS I got a black empty view. This is happening in Simulator and Device.

我做错了什么?

代码如下:

-(void)prepareToShow:(NSString*)filePath fileType:(NSString*)fileType request:(NSURLRequest*)request{

UIWebView *webView = (UIWebView*)self.view;
self.actualFilePath = filePath;

NSLog(@"File Path %@",filePath);

NSString *mimeType = @"";
if ([fileType caseInsensitiveCompare:@"PDF"]==NSOrderedSame){
    mimeType = @"application/pdf";
} else  if ([fileType caseInsensitiveCompare:@"DOC"]==NSOrderedSame){
    mimeType = @"application/msword";
} else  if ([fileType caseInsensitiveCompare:@"XLS"]==NSOrderedSame){
    mimeType = @"application/vnd.ms-excel";
}

[webView loadData:[NSData dataWithContentsOfFile:filePath] MIMEType:mimeType textEncodingName:@"UTF-8" baseURL:[NSURL URLWithString:@"http://www.google.com"]];

}

推荐答案

为了加载word或excel或pdf文档，你需要的是文档文件的物理路径.这意味着文件应该保存在文档或临时目录中，或者它可能在应用程序包中.

For loading word or excel or pdf documents, you need is physical path of document file. it means file should saved in document or temporary directory or it may be in application bundle.

//now use file path to load in webview
[yourWebView loadRequest:[NSURLRequest requestWithURL:[NSURL  fileURLWithPath:yourFilePath]]];
