ios - CallKit:如何区分拒绝调用和结束连接调用

Question

假设一个应用程序一次支持两个调用。第一个电话已接通，第二个电话打进来。一个得到“结束通话和接听电话”、“拒绝”、“保持通话和接听电话”按钮。

如果是“挂断接听电话”，则表示结束已接通的通话并接听新来电。
在“拒绝”的情况下，意味着拒绝来电。

在这两种情况下，代表

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

被触发。现在，如何知道要结束哪些调用，来电还是已接通的调用？ CXEndCallAction没有说明“拒绝”或“结束已连接调用”的原因

有没有人有办法解决吗？

Answer 1

我发现有一个事务列表委托(delegate):

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

如果有一个事务会触发其他委托(delegate)，例如 CXSetHeldCallAction，那么实现这个委托(delegate)将提供足够的信息。或 CXEndCallAction .所以现在我可以决定触发什么 Action ，并在必要时绕过其他代表。

如果其他人在苦苦挣扎，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;
}
