MAC的屏幕保护程序启动事件 [英] mac screensaver start event

问题描述

有没有屏保启动时触发的事件？像钥匙扣锁定：

  OSStatus keychain_locked（SecKeychainEvent keychainEvent，SecKeychainCallbackInfo *信息，无效*上下文）{...}
 

解决方案

终于找到了 - 该解决方案是使用NSDistributedNotificationCenter并遵守如下因素的事件

• com.apple.screensaver.didstart


• com.apple.screensaver.willstop


• com.apple.screensaver.didstop


• com.apple.screenIsLocked


• com.apple.screenIsUnlocked

如同

  [NSDistributedNotificationCenter defaultCenter]
   的addObserver：自我
   选择：@选择（screensaverStarted :)
   名：@com.apple.screensaver.didstart
   对象：无];
 

Is there an event fired when screensaver starts? Like for keychain locking:

OSStatus keychain_locked(SecKeychainEvent keychainEvent, SecKeychainCallbackInfo *info, void *context){...}

解决方案

Finally found it — the solution is to use NSDistributedNotificationCenter and observe folowing events

• com.apple.screensaver.didstart
• com.apple.screensaver.willstop
• com.apple.screensaver.didstop
• com.apple.screenIsLocked
• com.apple.screenIsUnlocked

Like

[[NSDistributedNotificationCenter defaultCenter]
   addObserver:self
   selector:@selector(screensaverStarted:)
   name:@"com.apple.screensaver.didstart"
   object:nil];
