退出可可的其他应用程序 [英] Quitting other applications in cocoa

问题描述

我需要在可可中退出其他应用程式。我有一个userInfo字典从通知，告诉我应用程序的名称。我尝试了方法terminate和forceTerminate，但他们没有工作（我认为他们只有在雪豹。）

I need to quit other applications in cocoa. I have a userInfo dictionary from a notification that tells me the name of the application. I tried the methods terminate and forceTerminate, but they did not work (I think they are only available in snow leopard.)

推荐答案

解决方案（占用OS X的最后3-4个版本中可用的所有不同的API）将使用AppleScript。只要生成必要的脚本在Obj-C / Python / Java无论你是真正使用（我假设Obj-C，因为你特别说在可可）。并使用NSAppleScript类（一个假设的例子）执行它：

The best solution (accounting for all the different API's available in the last 3-4 versions of OS X) is going to be using AppleScript. Just generate the necessary script in Obj-C/Python/Java whatever it is you are actually using (I'm assuming Obj-C since you specifically said 'In Cocoa'). And execute it using the NSAppleScript class (a contrived example):

// Grab the appName
NSString *appName = [someDict valueForKey:@"keyForApplicationName"];
// Generate the script
NSString *appleScriptString = 
    [NSString stringWithFormat:@"tell application \"%@\"\nquit\nend tell",
                               appName];
// Execute the script
NSDictionary *errorInfo = nil;
NSAppleScript *run = [[NSAppleScript alloc] initWithSource:theScript];
NSAppleEventDescriptor *theDescriptor = [run executeAndReturnError:&errorInfo];
// Get the result if your script happens to return anything (this example
//  really doesn't return anything)
NSString *theResult = [theDescriptor stringValue];
NSLog(@"%@",theResult);

这有效地运行一个脚本（如果appName是'Safari'）：

This effectively runs a script that (if appName was 'Safari') looks like:

tell application "Safari"
quit
end tell
