[英]Playing system click sound in iOS keyboard extension
I have followed the instructions on both these links: 我已经按照这两个链接上的说明进行操作:
How to play keyboard click sound in custom keyboard? 如何在自定义键盘中播放键盘点击声音?
https://developer.apple.com/library/ios/documentation/StringsTextFonts/Conceptual/TextAndWebiPhoneOS/InputViews/InputViews.html https://developer.apple.com/library/ios/documentation/StringsTextFonts/Conceptual/TextAndWebiPhoneOS/InputViews/InputViews.html
and done the following: 并执行以下操作:
header: 标头:
@interface Key : UIView <UIInputViewAudioFeedback>
implementation: 实施:
- (BOOL) enableInputClicksWhenVisible {
return YES;
}
- (void)tapped:(UITapGestureRecognizer *)sender
{
[[UIDevice currentDevice] playInputClick];
[self.delegate keyHit:_title];
}
Yet it is still not working. 但是它仍然无法正常工作。 What have I missed?
我错过了什么?
Try this code any time you want to play system click sound in a keyboard extension: 每当您想播放键盘扩展名中的系统点击声音时,请尝试以下代码:
+ (void)keyboardClickSound {
// Check system preference for current setting of Keyboard Click Sound.
CFStringRef applicationID = CFSTR("/var/mobile/Library/Preferences/com.apple.preferences.sounds");
Boolean keyExistsAndHasValidFormat;
BOOL enableInputClicks
= CFPreferencesGetAppBooleanValue(CFSTR("keyboard"), applicationID, &keyExistsAndHasValidFormat);
// Note: If the key does not exist because it has never been changed by a user,
// set it to the default, YES.
if (!keyExistsAndHasValidFormat)
enableInputClicks = YES;
// Play Keyboard Click Sound, if enabled.
// Note: If Open Access=Off, no click sound.
if (enableInputClicks)
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0),
^{ AudioServicesPlaySystemSound(1104); });
}
If your keyboard extension app contains "RequestsOpenAccess" field to YES, 如果您的键盘扩展程序应用程序的“ RequestsOpenAccess”字段为“是”,
Then keyboard click sound must need "Allow full Access" switch to On from 然后,键盘点击声音必须需要将“允许完全访问权限”从
General > Keyboard > Keyboards > Your_keyboard setting. 常规>键盘>键盘> Your_keyboard设置。
If It is Off then you can not play keyboard key sound. 如果关闭,则无法播放键盘按键声音。
