Question

我使用下面的代码验证我的Shopify结帐是否成功...但行：

 [self.client getCompletionStatusOfCheckout:self.checkout
 completion:^(BUYCheckout *checkout, BUYStatus status, NSError *error)
 {

给我一个最奇怪的错误：

＆＃34;不兼容的块指针类型发送＆＃39; void（^）（BUYCheckout * ___强，BUY状态，NSError * ___强＆＃39;参数类型＆＃39; BUYDataCheckoutStatusBlock＆＃39;＆＃39;

我该如何解决这个问题？这是什么意思？如果您需要更多代码/详细信息，请与我们联系。欢呼声。

·H

@property (nonatomic, strong) BUYClient *client;

的.m

-(void)verifyCheckout{

    __block BUYStatus buyStatus = BUYStatusUnknown;
    __block BUYCheckout *completedCheckout = self.checkout;
    dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);
    do {

        [self.client getCompletionStatusOfCheckout:self.checkout completion:^(BUYCheckout *checkout, BUYStatus status, NSError *error) {
            completedCheckout = checkout;
            buyStatus = status;
            dispatch_semaphore_signal(semaphore);
        }];
        dispatch_semaphore_wait(semaphore, DISPATCH_TIME_FOREVER);
        if (buyStatus == BUYStatusProcessing) {
            [NSThread sleepForTimeInterval:0.5];
        } else {

        }

    } while (completedCheckout.token && buyStatus != BUYStatusFailed && buyStatus != BUYStatusComplete);

}

Shopify文档说完成块只接受两个参数：

typedef void (^BUYDataCheckoutStatusBlock)(BUYStatus status, NSError *error);

所以行

 [self.client getCompletionStatusOfCheckout:self.checkout
 completion:^(BUYCheckout *checkout, BUYStatus status, NSError *error)
 {

应该是

[self.client getCompletionStatusOfCheckout:self.checkout
 completion:^(BUYStatus status, NSError *error)
 {

获取错误：＆＃34;不兼容的块指针类型发送＆＃39; void（^）＆＃34;？
