UILocalNotification无法正常工作... iPhone 4 iOS 4.3上没有振动 [英] UILocalNotification Not Working ... No Vibration on iPhone 4 iOS 4.3
问题描述
我会写尽可能多的内容，但标题几乎说明了一切.我已经在几种不同的情况下对其进行了测试:
I would write as much as I could write here, but the Title pretty much says it all. I've tested it in several different situations:
我知道这通过应用程序委托的didReceiveLocalNotification进行，并且没有声音或振动，除了我在didReceiveLocalNotification下包含的处理代码之外.实际称为
I know that this goes through app delegate's didReceiveLocalNotification and didn't expect a sound or vibration, except for the handling code that I included under didReceiveLocalNotification. The handling code actually called
NSURL *Sound = [[NSBundle mainBundle] URLForResource: self.currentSoundPVC
withExtension: @"caf"];
// Create a system sound object representing the sound file.
AudioServicesCreateSystemSoundID (soundFileURLRef,&soundFileObject);
AudioServicesPlayAlertSound (soundFileObject);
这确实有效！它会播放声音并同时振动手机.
and that actually works! It plays a sound and vibrates the phone simultaneously.
现在，我使用以下代码在应用程序委托的applicationDidEnterBackground中设置uilocalnotification警报
Now, I set up my uilocalnotification alarms in app delegate's applicationDidEnterBackground, using the following code
NSString *Sound = [self.currentSoundPVC stringByAppendingString:@".caf"];
UILocalNotification* alarm = [[[UILocalNotification alloc] init] autorelease];
alarm.fireDate = [NSDate dateWithTimeIntervalSinceNow:seconds];
[alarm setSoundName:Sound];
[[UIApplication sharedApplication] scheduleLocalNotification:alarm];
，这仅部分起作用！声音被播放，但是没有振动！现在，我认为这是一个错误，因为我是从Apple开发人员网站
and this only partially works! The sound gets played but there is NO VIBRATION! Now, this I think is a bug because I am quoting from the apple developer website,
http://developer.apple.com/library/ios/#documentation/iphone/conceptual/iphoneosprogrammingguide/BackgroundExecution/BackgroundExecution.html, Scheduling the Delivery of Local Notifications section:
发送通知并播放声音时，系统还会在支持该通知的设备上触发振动."
"When the notification is sent and the sound is played, the system also triggers a vibration on devices that support it. "
现在，很明显，这不是我的iPhone的情况，而且模拟器显然没有振动，因此我无法对其进行测试，并希望在开发人员社区中解决此问题！
Now, obviously that is NOT THE CASE for my iPhone and obviously the simulator doesn't vibrate, so I can't test this and would like to have this addressed in the developer community!
与#2相同
与#2相同
与#2相同，因为uilocalnotifications从未被取消，因此iOS仍然认为它们是有效的.
Same as #2, because the uilocalnotifications were never cancelled, so the iOS still thinks they are valid.
没有声音，没有振动，什么都没有！糟透了！我本来希望苹果能像往常一样直接开箱即用！
no sound, no vibration, NOTHING! This sucks! I would have hoped that apple would have come up with something that works straight out of the box, as usual!
推荐答案
这些是选项和效果(均假定音量设置为某个合理的值):
These are the options and the effects (all assume the volume is set to some reasonable value):
配置:
- [由开发人员控制]在UILocalNotification中设置的有效声音名称=否
- 该应用的[用户控制]通知中心设置:声音=不适用
- [用户控制]静默模式(iPhone侧面的开关)= N/A
行为:
- 发出通知时声音=否
- 以通知=否振动
配置:
- 在UILocalNotification中设置的有效声音名称=是
- 该应用程序的通知中心设置:声音" =关闭"
- 静音模式(iPhone侧面的开关)= N/A
行为:
- 发出通知时声音=否
- 以通知=否振动
配置:
- 在UILocalNotification中设置的有效声音名称=是
- 应用程序的通知中心设置:声音=开"
- 静音模式(iPhone侧面的开关)=否(未选择)
行为:
- 发出通知时发出的声音=是
- 以通知=否振动
配置:
- 在UILocalNotification中设置的有效声音名称=是
- 应用程序的通知中心设置:声音=开"
- 静音模式(在iPhone侧面打开)=是(已选择)
行为:
- 发出通知时声音=否
- 通过通知振动=是
