NSAppleScript自动打开iTunes

Question

当iTunes关闭时，不应该得到歌名，因为iTunes必须打开它才能检查并返回false。

请帮忙。

//run applescript 
NSAppleScript *script = [[NSAppleScript alloc] initWithSource:@"try\n tell application \"System Events\" to set checkIfItunesIsRunning to (name of processes) contains \"iTunes\"\n if checkIfItunesIsRunning is equal to true then\n tell application \"iTunes\" to get name of current track\n else\n return \"No Song\"\n end if\n on error errmsg number errNum\n return \"No Song\"\n end try"]; 

NSAppleEventDescriptor *theResult = [script executeAndReturnError:nil]; 
//Set MenuItem 
    [song setTitle:[theResult stringValue]];

你可能有更好的运气的东西，如：

if ([[NSRunningApplication runningApplicationsWithBundleIdentifier:@"com.apple.iTunes"] count] != 0) { 
    // run your script 
} else { 
    // itunes isn't running 
}
