我想设置电子邮件共享主题UIActivityViewController,也想在Twitter上分享.我知道在Twitter上我们想分享 - 我们需要将文本压缩到140个字符.我检查了许多SO解决方案,但没有任何工作.

最新的iOS版本是否修复了此问题？还有其他"工作方案"吗？

我正在为来自美国以外的美国客户开发使用Apple Pay的应用程序.我正在使用Braintree + Apple Pay.我们支持真实的信用卡到Passbook,但我们无法验证它们.

我成功生成了一个客户端令牌,self.braintree并尝试了BT的两种集成方式.

1. BTPaymentProvider - 我们对付款方式创建的抽象.

   if(self.braintree && ![self.braintree isKindOfClass:[NSNull class]])
   {
       self.provider = [braintree paymentProviderWithDelegate:self];
       if ([self.provider canCreatePaymentMethodWithProviderType:BTPaymentProviderTypeApplePay])
       {
           self.provider.paymentSummaryItems = @[[PKPaymentSummaryItem summaryItemWithLabel:@"XXXX" amount:[NSDecimalNumber decimalNumberWithString:@"1"]]];
       }
       [self.provider createPaymentMethod:BTPaymentProviderTypeApplePay];
   }

   但它没有推动" PKPaymentAuthorizationViewController".跟踪它也不例外.

2. PassKit - Apple的ApplePay API.

   if([PKPaymentAuthorizationViewController canMakePayments]) // It returns TRUE
   {
       PKPaymentRequest *paymentRequest = [[PKPaymentRequest alloc] init];
       paymentRequest.countryCode = @"US";
       paymentRequest.currencyCode = @"USD";
       paymentRequest.merchantCapabilities = PKMerchantCapabilityEMV | PKMerchantCapability3DS;
       paymentRequest.merchantIdentifier = MERCHANTID;
       paymentRequest.supportedNetworks = @[PKPaymentNetworkAmex, PKPaymentNetworkMasterCard, PKPaymentNetworkVisa];
       paymentRequest.paymentSummaryItems = @[ [PKPaymentSummaryItem summaryItemWithLabel:@"TEST" amount:[NSDecimalNumber …

我想在 Objective c 中使用正则表达式检查字符串。我的代码

NSString *regexAmazonOrder =@"[a-zA-Z0-9]*";
NSPredicate *predicateAmazonOrder = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regexAmazonOrder];

if([predicateAmazonOrder evaluateWithObject:cardNumber.text])
{
    NSLog(@"Its coming inside AMAZON ORDER EVALUATIONS");
    ...
}

但它不起作用。帮帮我。我知道这很简单，但是却让我心碎！！！谢谢

• 如何提取电子邮件、电话号码等值。我成功获得了帐单和送货地址。但是，我无法获得电子邮件和电话号码。请以编程方式建议我......（使用 kABPersonEmailProperty 等）

  • 此外，在

      (void) paymentAuthorizationViewController:(PKPaymentAuthorizationViewController*)controller
    
           didSelectShippingAddress:(ABRecordRef)address
                         completion:(void (^)(PKPaymentAuthorizationStatus, NSArray *, NSArray *))completion
      {
                -------- // I am getting street property Nil. 
      }

所有人都建议从“didAuthorizePayment”获取，但我需要根据“街道”（如 POBox 位置等）动态生成运费。建议我解决这种情况。

虽然我们有很多人问同样的问题,但没有一个答案有助于解决我的问题.所以这是我的代码,

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

    NSString *text = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSLog(@"Response: %@", text);



    //The NSJSONSerialization method to transform the NSData responseObject into a dictionnary does work
    NSJSONSerialization *jsonResponse = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:nil];

    //This NSLog makes the app crash with an unrecognized selector sent error
    NSLog(@"JSON: %@",jsonResponse);

    NSArray *result1=(NSArray *)[jsonResponse valueForKeyPath:@"result"];

    NSLog(@"result1: %@",result1);

    NSMutableString  *shipPrice =[[NSMutableString alloc]init];
    NSMutableString  *freeLimitString =[[NSMutableString alloc]init];

    if(result1!=Nil && ![result1 count]==0)
    {
               for (int i=0; i<result1.count; i++) …
