问题 Can "Full Keyboard Access" (System Prefs -> Keyboard -> (Radio) All Controls) be controlled with some API? It causes major issues when this thing is on in my app (like buttons not working as expected etc ... it has some custom UI) Regards, Erik 回答1: Override nextValidKeyView and previousValidKeyView in your custom view to return something sane, or set the view's nextKeyView and previousKeyView to specific views if detecting valid key views automatically isn't possible. If Full Keyboard Access

问题 I'm new to Swift and I am struggling with NSTableView! I'm trying to create a custom NSTableCellView from a NIB. I want to load the cell from a NIB because: - it will be reused in multiple columns and multiple table-views - it will be visually and functionally complex (relatively) - it is likely to evolve during development I'm able to load the cell in my table view but I'm getting a "Failed to connect outlet from... missing setter or instance variable" error in the debug area when I try to

问题 The title of the question really says it all. I am trying to tie in AppKit elements like buttons and other controls into a OS X SpriteKit game. My understanding is that AppKit elements can be placed on top of SKScenes, but how does this work? Would this be handled via an NSView? How does the layer get created in SpriteKit or is this a separate process altogether? 回答1: All AppKit UI elements are subclasses of NSResponder and most are subclasses of NSView This means like any other Cocoa app,

问题 I have several WebViews that I swap in and out of my view hierarchy. Some of these WebViews contain form fields, so I implement the editingDelegate to provide the NSUndoManager for my document. The problem is that any typing done in the WebView generates actions that are placed on the undo stack. After the view is removed from the hierarchy, the actions are still in the undo stack. At that point, if a user uses Cmd-Z to "Undo Typing", an exception is thrown because -undoEditing: is being sent

问题 I am creating a grouped NSTableView that loads just fine and with all my objects the way I want to. I also created the possibility to collapse entire group sections (the rows between group rows) and I use the hideRowsAtIndexes:withAnimation: and unhideRowsAtIndexes:withAnimation: that were added to NSTableView ( https://developer.apple.com/library/mac/releasenotes/AppKit/RN-AppKit/#10_11TableView). Hiding always seem to work, but unhiding crashes for some rows. The last row hides and unhides

问题 I have an NSTextField that contains an NSAttributedString which itself contains a clickable link.

问题 On mountain lion, I try the new sharing possiblities with the NSSharingService class of AppKit.framework Everything goes fine with this kind of code NSArray* array = @[ @"myText", [NSImage imageNamed:@"myImageFile"] ]; NSSharingService* sharingServiceFB = [NSSharingService sharingServiceNamed:NSSharingServiceNamePostOnFacebook]; [sharingServiceFB performWithItems:array]; But I'd like to do the same without the sharing window generated by the performWithItems function. As I'm considering that

问题 I want to get a thumbnail representation of a file I have to display in my app. I'm using NSURL here: NSDictionary *thumbnails = nil; BOOL success = [fileURL getResourceValue:&thumbnails forKey:NSURLThumbnailDictionaryKey error: &error]; This works fine if I am connected to iCloud, and the URL is a link to a file stored in iCloud. The fileURL is something like: file:///Users/me/Library/Mobile%20Documents/BJXXGLR9R3~com~myapp~icloud/FileStorage/contact-page%20copy.png If I use the same code
