Question

我有几个像这样的NSStrings：

@property (nonatomic, copy,   readonly) NSString          *browserName;
@property (nonatomic, copy,   readonly) NSString          *browserVersion;
@property (nonatomic, copy,   readonly) NSString          *browserMajor;
@property (nonatomic, copy,   readonly) NSString          *operatingSystemName;

我如何使用UIDocumentInteractionController获取这些字符串并创建可以共享，发送电子邮件，复制等文档

我已经在我的应用程序中显示了文档控制器，我只是不知道如何使用这些字符串中的信息填充文件。

我是这样做的：

NSArray *visitorInfoArray = [NSArray arrayWithObjects:@"Visitor Location", _visitor.location, @"currentURL", _visitor.currentURL, nil];
    NSString *visitorInfo = [visitorInfoArray componentsJoinedByString:@" "];

    NSString *filename = @"User Info";
    NSURL *tempURL = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:filename]];
    [visitorInfo writeToURL:tempURL atomically:YES encoding:NSUTF8StringEncoding error:nil];
    [MTq main:^{
        [FCIProgress dismiss];
        DLog(@"%@", visitorInfo);
        self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:tempURL];
        self.documentInteractionController.UTI = @"public.plain-text";
        [self.documentInteractionController presentOptionsMenuFromBarButtonItem:sender animated:YES];
    }];

使用UIDocumentInteractionController从多个NSStrings创建文档
