CallKit：如何区分拒绝呼叫和结束连接呼叫

Question

假设一个应用程序同时支持两个调用。第一个电话接通，第二个电话打进来。一个人得到 "end call & answer call"、"decline"、"hold call and answer call" 按钮。

如果是"end call & answer call"，则表示结束已接通的电话，接听新的电话。 "decline"表示拒接来电

在这两种情况下，代表

- (void)provider:(CXProvider *)provider performEndCallAction:(CXEndCallAction *)action

被触发。现在，应该如何知道要结束这些呼叫中的哪一个，是来电还是已接通的呼叫？ CXEndCallAction 没有说明 "decline" 或 "end-already-connected call"

的原因

有人有解决办法吗？

Answer 1

您需要访问 CXEndCallAction 的 callUUID 成员。

交易是在正确的对象上调用的，因此您只需终止与传输的 UUID 匹配的调用。这意味着您必须将对 UUID 的支持添加到您自己的调用对象模型中。

Answer 2

我发现有一个交易列表委托：

- (BOOL)provider:(CXProvider *)provider executeTransaction:(CXTransaction *)transaction

如果有交易会触发其他委托，例如 CXSetHeldCallAction 或 CXEndCallAction，则实施此委托将提供足够的信息。所以现在我可以决定触发什么操作，并在必要时绕过其他代表。

如果其他人正在苦苦挣扎，这是我的代码：

- (BOOL)provider:(CXProvider *)provider executeTransaction:(CXTransaction *)transaction
{
NSLog(@"executeTransaction : %@", transaction.debugDescription);
BOOL callEnd = NO;
BOOL callHold= NO;
BOOL callAnswer = NO;

NSPredicate *filter = [NSPredicate predicateWithFormat:@"self isKindOfClass: %@", [CXEndCallAction class]];
NSArray *ends = [transaction.actions filteredArrayUsingPredicate:filter];
callEnd = [ends count] >= 1;

filter = [NSPredicate predicateWithFormat:@"self isKindOfClass: %@", [CXAnswerCallAction class]];
NSArray *answer = [transaction.actions filteredArrayUsingPredicate:filter];
callAnswer = [answer count] >= 1;

filter = [NSPredicate predicateWithFormat:@"self isKindOfClass: %@", [CXSetHeldCallAction class]];
NSArray *hold = [transaction.actions filteredArrayUsingPredicate:filter];
callHold = [hold count] >= 1;

if(callEnd && callAnswer)
{
    actionType = kCallKitEndAndAnswer;
    [[MyCallManager sharedManager] endPreviousCallAndAnswerNewCall:^(BOOL succeeded) {
        NSLog(@"end answered call: %@", succeeded ? @"yes" : @"No");
        CXEndCallAction *en = [ends firstObject];
        succeeded ? [en fulfill] : [en fail];

        CXAnswerCallAction *an= [answer firstObject];
        succeeded ? [an fulfill] : [an fail];

    }];
    return YES;
}
else if(callHold && callAnswer)
{
    actionType = kCallKitHoldAndAnswer;

    [[MyCallManager sharedManager] answerCall:^(BOOL succeeded) {
        NSLog(@"hold answered call: %@", succeeded ? @"yes" : @"No");
        CXSetHeldCallAction *ho = [hold firstObject];
        succeeded ? [ho fulfill] : [ho fail];

        CXAnswerCallAction *an= [answer firstObject];
        succeeded ? [an fulfill] : [an fail];
    }];
    return YES;
}
else if([hold count] == 2)
{
    [[MyCallManager sharedManager] swapCalls];
    usleep(25000);
    CXSetHeldCallAction * fi = [hold firstObject];
    CXSetHeldCallAction * la = [hold lastObject];
    [fi fulfill];
    [la fulfill];

    return YES;
}

return NO;
}

Answer 3

您可以使用枚举和 "isMemberOfClass"。

在providerDelegate.h

 // Call Modes.
 typedef NS_ENUM(NSUInteger, CallMode) {
     kUnknownMode = 0,
     kEndAndAnswerMode = 1,
     kHoldAndAnswerMode = 2
};

在providerDelegate.m

@property(nonatomic, assign) CallMode mode;

并添加以下代码以获取每笔交易。

- (BOOL)provider:(CXProvider *)provider executeTransaction:(CXTransaction *)transaction {

    NSLog(@"Provider execute transaction");

    BOOL callEnd = NO;
    BOOL callHold= NO;
    BOOL callAnswer = NO;

    NSPredicate *filter = [NSPredicate predicateWithFormat:@"self isMemberOfClass: %@", [CXEndCallAction class]];
    NSArray<CXEndCallAction *> *ends = [transaction.actions filteredArrayUsingPredicate:filter];
    callEnd = [ends count] >= 1;

    filter = [NSPredicate predicateWithFormat:@"self isMemberOfClass: %@", [CXAnswerCallAction class]];
    NSArray<CXAnswerCallAction *> *answers = [transaction.actions filteredArrayUsingPredicate:filter];
    callAnswer = [answers count] >= 1;

    filter = [NSPredicate predicateWithFormat:@"self isMemberOfClass: %@", [CXSetHeldCallAction class]];
    NSArray<CXSetHeldCallAction *> *holds = [transaction.actions filteredArrayUsingPredicate:filter];
    callHold = [holds count] >= 1;

    if(callEnd && callAnswer) {
        _mode = kEndAndAnswerMode;
    } else if(callHold && callAnswer) {
        _mode = kHoldAndAnswerMode;
    } else {
        _mode = kUnknownMode;
    }

    return NO;
}
