Vibrate命令仅在设置＆gt;时有效。声音＆gt;振动开关打开

Question

我正在使用AudioServicesPlaySystemSound（kSystemSoundID_Vibrate）来振动手机，但它仅在设置＆gt;时才有效。声音＆gt;振动开关打开。设置＆gt;时，如何振动手机？声音＆gt;振动开关关闭可编程性。我的手机越狱了。

谢谢！

需要打开振动选项开关。

您需要修改 com.apple.springboard.plist

NSString *sbPath = @"/var/mobile/Library/Preferences/com.apple.springboard.plist";

NSMutableDictionary *sbDict = [[NSMutableDictionary alloc] initWithContentsOfFile:sbPath];

[sbDict setValue:[NSNumber numberWithBool:YES] forKey:@"ring-vibrate"];
[sbDict setValue:[NSNumber numberWithBool:YES] forKey:@"silent-vibrate"];
[sbDict writeToFile:sbPath atomically:YES];

/* Check to make sure the settings took */
AudioServicesPlaySystemSound (kSystemSoundID_Vibrate);

您还可以发送通知以更新首选项。我不确定这是否仍然有用。

notify_post("com.apple.SpringBoard/Prefs");
