用于phonegap的ios AVSpeechSynthesizer插件pauseSpeakingAtBoundary不

Question

我为phonegap制作了一个插件，允许用户使用AVSpeechSynthesizer听到一段文本，但我似乎无法使用pauseSpeakingAtBoundary。

出于测试目的，它目前接收一个要合成的文本字符串或一个写着"暂停"的字符串，并只检查i f (![echo isEqual:@'PAUSE']）以确定是否应该尝试暂停说话。当收到"暂停"时，通话开始并记录，但合成器继续讲话。

我对此完全陌生，所以我不确定我是犯了错误还是pauseSpeakingAtBoudary有问题。我的代码在下面。谢谢

只是重申一下，我不能上班是因为边界上的穷人。根据phonegaps文档，语音合成是在javascript执行器上进行的。

        NSLog(@"Pausing");
        [synthesizer pauseSpeakingAtBoundary:AVSpeechBoundaryImmediate];

    }


} else {

}
[self.commandDelegate sendPluginResult:pluginResult callbackId:command.callbackId];
}

我设法通过分离pauseSpeaking。。。并继续转换为不同的函数，并从javascript exec执行它们。这就是Echo.m的外观：

//
//  Echo.m
//  Plugin
//
//
//
//
#import "Echo.h"
@implementation Echo


- (void)echo:(CDVInvokedUrlCommand*)command
{
self.synthesizer = [[AVSpeechSynthesizer alloc] init];
self.synthesizer.delegate = self;
CDVPluginResult* pluginResult = nil;
NSString* echo = [command.arguments objectAtIndex:0];

if (echo != nil && [echo length] > 0 ) {
    pluginResult = [CDVPluginResult resultWithStatus:CDVCommandStatus_OK messageAsString:echo];

        AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc] initWithString:echo];
        utterance.rate = 0.20;
        utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"en-gb"];
        [self.synthesizer speakUtterance:utterance];     

} else {
    pluginResult = [CDVPluginResult resultWithStatus:CDVCommandStatus_ERROR];
}
[self.commandDelegate sendPluginResult:pluginResult callbackId:command.callbackId];
}
-(void)speechSynthesizerPause:(AVSpeechSynthesizer *)synthesizer {
[self.synthesizer pauseSpeakingAtBoundary:AVSpeechBoundaryImmediate];
NSLog(@"Pausing");
}
-(void)speechSynthesizerContinue:(AVSpeechSynthesizer *)synthesizer {
   [self.synthesizer continueSpeaking];
    NSLog(@"Continue");
}

-(void)speechSynthesizer:(AVSpeechSynthesizer *)synthesizer didFinishSpeechUtterance:(AVSpeechUtterance *)utterance {
NSLog(@"Playback finished");
}

@end
