问题 I'm trying to use either an NSTextView or NSTextField which displays text that I am adding via textField.stringValue = [dictionary objectForKey:@"info"]; The problem is I need the bounds / frame of the text area to vertically re-size to show all of the text. The text varies from a couple of words (1 line) to a paragraph or two. When I try [textField sizeToFit]; It re-sizes the whole thing down to a single line which is absurdly too long (and goes off view). I need it to auto re-size its width

问题 This should be simple but I cannot understand how to implement this action. I found this reference using objective-c but I want to do this using swift: - (NSArray<NSTableViewRowAction *> *)tableView:(NSTableView *)tableView rowActionsForRow:(NSInteger)row edge:(NSTableRowActionEdge)edge { NSTableViewRowAction *action = [NSTableViewRowAction rowActionWithStyle:NSTableViewRowActionStyleDestructive title:@"Delete" handler:^(NSTableViewRowAction * _Nonnull action, NSInteger row) { // TODO: You

问题 I'm working on a preferences window for my app, where the user can add and remove presets using NSTableView . A preset is defined as: struct Preset: Codable { var name: String var value: Int } These presets should be persisted to UserDefaults . My goal is to write as little code as possible, and what little is written should be generic code, so my project makes use of NSUserDefaultsController , NSArrayController and Cocoa Bindings. Seeing as array, string and integer types are available in

问题 I'm facing a rather odd problem. With subclassing some NSViews, NSTableView and NSScrollView to be specific. Situation : I'm working on a quite old (ca. 7 year) project for macOS. The codebase is about 50% objc and 50% swift 3.2 and uses XIB files for the individual views. The application runs smoothly on 10.10 - 10.12 but it crashes on 10.13 pretty much instantly. The backtrace shows the following: * thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address

问题 I use view-based NSTableView in my Cocoa app which is written in Swift, and want to implement a sort functionality on two table columns. However, in Objective-C, you can implement it by first setting the "Sort Key" in Attribute Inspector, and then implement the data source delegate method named tableView: sortDescriptorsDidChange: . However, this method takes sortDescriptor as a parameter and lets developers use it within the method, like so: - (void) tableView:( NSTableView *) tableView

问题 I have a Cocoa app with a view-based table view bound to an NSArrayController with a list of custom Employee objects. The table view shows the list of employees. In a subview, the employee's details can be changed. Everything is set up, so that when an employee's details are changed, the table view contents are reloaded, showing the changes. So far, so good. Now NSArrayController has the ability to preserve the selected object across reloads via preservesSelection . For my custom Employee

问题 I have an NSTableView that contains 2 different Columns - one is an NSImageCell that shows a file icon, and the second is a custom subclass of NSTextFieldCell that contains a quick look button on the right of the text. When I click the Quick Look button, the following code is invoked: [[QLPreviewPanel sharedPreviewPanel] makeKeyAndOrderFront:nil]; This does it's job and shows the blank Quick Look panel saying "No Items Selected." After I did a bit of research on the internet, I implemented a
