Question

我从WebKit框架创建了一个自定义浏览器。我几乎完成了所有设置。

然而，当访问带有文件上传的网页（比如flickr）时，按下“上传”按钮时没有任何反应。通常这会在safari / firefox /..

中弹出一个弹出窗口

在Cocoa中使用WebKit进行文件上传需要什么？ NSFileHandler，NSFileManager？我该怎么做？

此致 Friesgaard

Answer 1

好吧，我认为我是出于自我。

在类中实现以下方法。在Interface Builder中将类设置为UIDelegate的{{1}}。

（如何使用我在此处找到的WebView： http://ekle.us/index.php/2006/12/displaying_a_file_open_dialog_in_cocoa_w ）

NSOpenPanel

PS。将- (void)webView:(WebView *)sender runOpenPanelForFileButtonWithResultListener:(id < WebOpenPanelResultListener >)resultListener { // Create the File Open Dialog class. NSOpenPanel* openDlg = [NSOpenPanel openPanel]; // Enable the selection of files in the dialog. [openDlg setCanChooseFiles:YES]; // Enable the selection of directories in the dialog. [openDlg setCanChooseDirectories:NO]; // Display the dialog. If the OK button was pressed, // process the files. if ( [openDlg runModalForDirectory:nil file:nil] == NSOKButton ) { // Get an array containing the full filenames of all // files and directories selected. NSArray* files = [openDlg filenames]; // Loop through all the files and process them. //for(int i = 0; i < [files count]; i++ ) { NSString* fileName = [files objectAtIndex:0]; //i]; // Do something with the filename. [resultListener chooseFilename:fileName]; } } }用于多个文件

我通过改变这一点来实现它，因为表单部分已经折旧：

- (void)webView:(WebView *)sender runOpenPanelForFileButtonWithResultListener:(id < WebOpenPanelResultListener >)resultListener
{       
    // Create the File Open Dialog class.
    NSOpenPanel* openDlg = [NSOpenPanel openPanel];

    // Enable the selection of files in the dialog.
    [openDlg setCanChooseFiles:YES];

    // Enable the selection of directories in the dialog.
    [openDlg setCanChooseDirectories:NO];

    if ( [openDlg runModal] == NSOKButton )
    {
        NSArray* URLs = [openDlg URLs];
        NSMutableArray *files = [[NSMutableArray alloc]init];
        for (int i = 0; i <[URLs count]; i++) {
            NSString *filename = [[URLs objectAtIndex:i]relativePath];
            [files addObject:filename];
        }

        for(int i = 0; i < [files count]; i++ )
        {
            NSString* fileName = [files objectAtIndex:i];
            [resultListener chooseFilename:fileName]; 
        }
        [files release];
    }

}
