NSSavePanel File Path

Question

I use NSSavePanel only when I deal with text files. If I have an image to export, I use NSOpenPanel so that the user can select a directory, and I don't get caught with in the sandbox file path restriction. This time, though, I want to use NSSavePanel to let the user save an image file (bmp, gif, jpeg, jp2, png).

- (void)exportfile {    
    NSString *documentFolderPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
    NSSavePanel *panel = [NSSavePanel savePanel];

    [panel setMessage:@"Please select a path where to save checkboard as an image."]; // Message inside modal window
    if ([self fileExists:destinationpath]) {
        [panel setDirectoryURL:[NSURL fileURLWithPath:destinationpath]];
    } else {
        [panel setDirectoryURL:[NSURL fileURLWithPath:documentFolderPath]];
    }

    //[panel setAllowedFileTypes:[[NSArray alloc] initWithObjects:@"bmp",@"gif",@"jpg",@"jp2",@"png",nil]];
    [panel setAllowsOtherFileTypes:YES];
    [panel setExtensionHidden:YES];
    [panel setCanCreateDirectories:YES];
    [panel setNameFieldStringValue:filename];
    [panel setTitle:@"Saving checkboard..."]; // Window title
    [panel setAccessoryView:accessoryView1];

    NSInteger result = [panel runModal];
    NSError *error = nil;

    if (result == NSOKButton) {     
        ////////////////////////////////////////////
        NSString *path0 = [[panel URL] path];
        NSMutableString *path1 = [[NSMutableString alloc] initWithString:path0];
        if (formatIndex1 == 0) { // formatIndex1 is the index of NSPopMenu
            [path1 appendString:@".bmp"];
        }
        else if (formatIndex1 == 1) {
            [path1 appendString:@".gif"];
        }
        else if (formatIndex1 == 2) {
            [path1 appendString:@".jpg"];
        }
        else if (formatIndex1 == 3) {
            [path1 appendString:@".jp2"];
        }
        else if (formatIndex1 == 4) {
            [path1 appendString:@".png"];
        }
        [self exportfile2:path1]; // <<<<<<<<<<<<<<< Immediate goal
        ////////////////////////////////////////////

        if (error) {
            [NSApp presentError:error];
        }
    }
}

This NSSavePanel has an AccessoryView control, allowing the user to select a graphic format with an NSPopupMenu. Its index is formatIndex1. I know that the code fails if the application is sandboxed. That's because the exact path that the user selects is path0, and the code above appends a file extension to it before reaching exportfile2. So how do I go about getting the exact path with a file extension. Preview automatically appends a file extension if 'Hide extension' is off. Yet, Preview won't fail to export an image.

Thank you for your help.

It seems that the last person at the following link has a solution. I'm not sure how to exactly implement it. http://t6580.codeinpro.us/q/5080f5b24f1eba38a4d13bd7 — El Tomato, Aug 26 '13 at 07:50

Try like this below:-

- (void)exportfile {    
    NSSavePanel *panel = [NSSavePanel savePanel];
NSString *fileName=nil;

        if (formatIndex1 == 0) { // formatIndex1 is the index of NSPopMenu
        fileName=@"untitle.bmp"
        }
        else if (formatIndex1 == 1) {
        fileName=@"untitle.gif"
        }
        else if (formatIndex1 == 2) {
          fileName=@"untitle.jpg"
        }

[panel setMessage:@"Please select a path where to save checkboard as an image."]; // Message inside modal window
    [panel setAllowsOtherFileTypes:YES];
    [panel setExtensionHidden:YES];
    [panel setCanCreateDirectories:YES];
    [panel setNameFieldStringValue:filename];
    [panel setTitle:@"Saving checkboard..."]; // Window title
    [panel setAccessoryView:accessoryView1];

    NSInteger result = [panel runModal];
    NSError *error = nil;

    if (result == NSOKButton) {     
        ////////////////////////////////////////////
        NSString *path0 = [[panel URL] path];


        [self exportfile2:path0]; // <<<<<<<<<<<<<<< Immediate goal
        ////////////////////////////////////////////

        if (error) {
            [NSApp presentError:error];
        }
    }
}

No. That's not going to solve anything because the exported file will simply lose a file extension, which would make the file unreadable unless the user manually adds an appropriate one. — El Tomato, Aug 26 '13 at 22:43
If you don't understand the issue, see the link that I've give at the top or see the following. http://stackoverflow.com/questions/1930352/nssavepanel-squelching-the-confirm-replace-dialog — El Tomato, Aug 29 '13 at 07:11
