To export to MS Word using Cocoa, you can use the NSAttributedString class to create an attributed string from your content, and then use the NSFileWrapper class to create a file wrapper to represent the Word document. Here is an example code snippet:
// Create an attributed string representing your content
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithString:@"Hello, World!"];
// Specify the file path for the Word document
NSString *filePath = @"~/Desktop/HelloWorld.docx";
NSURL *fileURL = [NSURL fileURLWithPath:[filePath stringByExpandingTildeInPath]];
// Create the file wrapper for the Word document
NSFileWrapper *fileWrapper = [[NSFileWrapper alloc] initRegularFileWithContents:nil];
fileWrapper.preferredFilename = fileURL.lastPathComponent;
fileWrapper.filename = fileURL.lastPathComponent;
// Create a Word exporter
NSSavePanel *savePanel = [NSSavePanel savePanel];
[savePanel setAllowedFileTypes:@[@"docx"]];
[savePanel setNameFieldStringValue:@"HelloWorld"];
[savePanel beginSheetModalForWindow:self.view.window completionHandler:^(NSInteger result) {
if (result == NSModalResponseOK) {
NSURL *saveURL = savePanel.URL;
NSData *wordData = /* call Word exporter */;
[wordData writeToURL:saveURL atomically:YES];
}
}];
// Write the attributed string to the file wrapper as RTF
NSError *error = nil;
NSData *rtfData = [attributedString dataFromRange:(NSRange){0, attributedString.length}
documentAttributes:@{NSDocumentTypeDocumentAttribute: NSRTFTextDocumentType}
error:&error];
if (rtfData) {
[fileWrapper addRegularFileWithContents:rtfData preferredFilename:@"document.rtf"];
} else {
NSLog(@"Error: %@", error.localizedDescription);
}
// Write the file wrapper to the Word document file
NSError *writeError = nil;
BOOL success = [fileWrapper writeToURL:fileURL
options:NSFileWrapperWritingAtomic
originalContentsURL:nil
error:&writeError];
if (!success) {
NSLog(@"Error writing file wrapper: %@", writeError.localizedDescription);
}
In this example, we create an attributed string representing the content we want to export, and then use the NSFileWrapper class to create a file wrapper to represent the Word document. We then write the RTF representation of the attributed string to the file wrapper, and finally write the file wrapper itself to the Word document file. The code also includes a NSSavePanel to allow the user to specify the file location and name for the Word document. Note that the Word exporter code is not included and would need to be implemented separately.
