NSAppleScript自動打開iTunes

Question

當iTunes關閉時，不應該得到歌名，因爲iTunes必須打開它才能檢查並返回false。

請幫忙。

//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]];

你可能有更好的運氣的東西，如：

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