There’s only two methods for the datasource. Mine look like this:
#pragma mark - QLPreviewPanelDataSource
- (NSInteger)numberOfPreviewItemsInPreviewPanel:(QLPreviewPanel *)panel
{
return [_arrayController selectedObjects].count; // returns ‘1'
}
- (id <QLPreviewItem>)previewPanel:(QLPreviewPanel *)panel previewItemAtIndex:(NSInteger)index
{
NSArray *pathArray = [[_arrayController selectedObjects] valueForKey:@"Path"];
NSString *pathString = pathArray[0];
NSURL *previewPath = [[NSURL URLWithString:pathString] absoluteURL];
return previewPath; //returns ‘Users/phil/Documents/sample.txt'
}
Best
