代码实现
NSLog(@"filpath------%@", filpath);NSData *Data = [NSData dataWithContentsOfFile:_filePath];NSString *type = [filpath componentsSeparatedByString:@"."].lastObject;if ([type isEqualToString:@"docx"]){[self.webView loadData:Data MIMEType:@"application/vnd.openxmlformats-officedocument.wordprocessingml.document" textEncodingName:@"UTF-8" baseURL:[NSURL fileURLWithPath:NSTemporaryDirectory()]];}else if ([type isEqualToString:@"doc"]){[self.webView loadData:Data MIMEType:@"application/msword" textEncodingName:@"UTF-8" baseURL:[NSURL fileURLWithPath:NSTemporaryDirectory()]];}else if([type isEqualToString:@"txt"]){[self.webView loadData:Data MIMEType:@"text/plain" textEncodingName:@"UTF-8" baseURL:[NSURL fileURLWithPath:NSTemporaryDirectory()]];}else if([type isEqualToString:@"PDF"] || [type isEqualToString:@"pdf"]){[self.webView loadData:Data MIMEType:@"application/pdf" textEncodingName:@"UTF-8" baseURL:[NSURL fileURLWithPath:NSTemporaryDirectory()]];}else if([type isEqualToString:@"PNG"] || [type isEqualToString:@"png"]){[self.webView loadData:Data MIMEType:@"image/png" textEncodingName:@"UTF-8" baseURL:[NSURL fileURLWithPath:NSTemporaryDirectory()]];}else if([type isEqualToString:@"ppt"]){[self.webView loadData:Data MIMEType:@"application/vnd.ms-powerpoint" textEncodingName:@"UTF-8" baseURL:[NSURL fileURLWithPath:NSTemporaryDirectory()]];}else if ([type isEqualToString:@"pptx"]){[self.webView loadData:Data MIMEType:@"application/vnd.openxmlformats-officedocument.presentationml.presentation" textEncodingName:@"UTF-8" baseURL:[NSURL fileURLWithPath:NSTemporaryDirectory()]];}else if ([type isEqualToString:@"xlsx"]){[self.webView loadData:Data MIMEType:@"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" textEncodingName:@"UTF-8" baseURL:[NSURL fileURLWithPath:NSTemporaryDirectory()]];}else if ([type isEqualToString:@"xls"]){[self.webView loadData:Data MIMEType:@"application/vnd.ms-excel" textEncodingName:@"UTF-8" baseURL:[NSURL fileURLWithPath:NSTemporaryDirectory()]];}else{}
