由 北慕城南 提交于 2019-12-07 11:25:38
问题 I have sandboxing enabled and use /sbin/ping with NSTask: [task setLaunchPath:@"/sbin/ping"]; [task setArguments:[NSArray arrayWithObjects:@"-c10", iPAddress, nil]]; Everything works great and I get the expected output. I also want to use /usr/sbin/traceroute with NSTask: [task setLaunchPath:@"/usr/sbin/traceroute"]; [task setArguments:[NSArray arrayWithObject:iPAddress]]; But the task terminates with the message: NSTask: Task create for path '/usr/sbin/traceroute' failed: 22, "Invalid

How can I reload the com.apple.systemuiserver preferences into the SystemUIServer application?

问题 For my Mac OSX application, I have a feature that removes the system clock in the upper right hand corner of the screen when a button is clicked. The preferences that control which system menus are displayed (including the system clock) is stored in ~/Library/Preferences/com.apple.systemuiserver.plist. I was able to update the relevant preferences in that file to remove the system clock. However, the SystemUIServer application needs to be restarted so that the new preferences can be reloaded

问题 I'm using NSTask to execute a series of long running commands like so: commandToRun = @"command 1;command2"; NSArray *arguments = [NSArray arrayWithObjects: @"-c", commandToRun, nil]; self.task = [[NSTask alloc] init]; [self.task setLaunchPath: @"/bin/sh"]; [self.task setArguments: arguments]; [self.task launch]; This creates a process for the shell, and a child process for whichever command is running at the time (command 1 or command 2). If I kill the task with [self.task terminate] it only

Ignoring user input while waiting for a task - Objective-C

由 淺唱寂寞╮ 提交于 2019-12-06 20:37:31
I have an app with a button 'convert'. When I click this button, the app starts a new process using NSTask and then greys out the button until the process finishes. My problem is, the app saves any clicks made by the user while it is waiting for the process to finish. So even though the button is grayed out, the user can click it and the process will immediately start again as soon as it finishes. I'm waiting for the process to finish using: [task waitUntilExit]; How do I ignore any user input while waiting for this task to finish? -[NSTask waitUntilExit] is, of course, a blocking call. That

If I can explain my self better knowing if a user is running some particular program such as word or chrome, etc. I will try to update my question as I write code or find more information. Thank you (: You don't have to go through NSTask , you can use Cocoa's NSWorkspace to get the list of running applications: import Cocoa let apps = NSWorkspace.sharedWorkspace().runningApplications It returns an array of NSRunningApplication objects. Let's say you want the running applications names in an array: let appsNames = apps.flatMap { $0.localizedName } If you want to know for example if iTunes is
