问题 Need to avoid the conformation dialog. 回答1: The dialog box a security feature of the keychain. Because it stores sensitive user information, the OS takes the position that the user should always have the option to prevent the use of this information so that the user can trust they're not being used without their knowledge.

问题 I have several NSViews that trigger re-draws during the mouseEntered and mouseExited methods. When showing an NSMenu in the same window, updating of those NSViews is suspended (they don't get the mouseEntered and Exited events). My problem is that once the NSMenu is closed (after moving the mouse all over the window outside of the NSMenu), every mouseEntered and Exited event that would have been triggered immediately trigger in a fast sequence. So basically they were queueing up and then

问题 How do I flip the y value of an NSPoint to a flipped coordinate space. I have two sources of points, both in global screen space, but one is flipped: one from a screen coordinate space with 0,0 = top left. one from a screen coordinate space with 0,0 = bottom left. I need to flip the second one (bottom left) to be in the same space as the first one, top left. How can I do that on an NSPoint or CGPoint? 回答1: For Mac OSX Cocoa, you can flip the y Coordinate for a view, just override isFlipped to

问题 I have an application consisting of the following single .m file: #import <Cocoa/Cocoa.h> int main(int argc, char* argv[]) { [[[NSThread alloc] initWithBlock: ^{ sleep(2); dispatch_async(dispatch_get_main_queue(), ^{ NSLog(@"Stop"); [[NSApplication sharedApplication] stop:nil]; }); }] start]; [[NSApplication sharedApplication] run]; NSLog(@"Run finished"); return 0; } According to the developer documentation, stop should stop the main loop ( run ), but it doesn't (at least not on OS X 10.12
