封裝第三方支付（支付寶、銀聯、微信支付）

今天對第三方支付作了一個小小的封裝，框架的導入與配置這裏就很少說了，能夠去看集成文檔。直接上封裝的demo

使用方式：[[SKAliPayTool sharedSKAliPayTool] goPayByPayType:payName
                                          andOrderNum:self.orderNumber
                                             andTitle:self.orderNumber
                                      andDescribetion:@"測試"
                                             andPrice:[self.goodsDictionary safeJsonObjForKey:@"FactPrice"]];
    
    [SKAliPayTool sharedSKAliPayTool].paySuccess = ^{
      
    };
    [SKAliPayTool sharedSKAliPayTool].payFailed = ^{
      
    };

首先.h文件

#import <Foundation/Foundation.h>
#import "SKSingle.h"
/**支付寶*/
#import <AlipaySDK/AlipaySDK.h>
#import "Order.h"
#import "DataSigner.h"

#import "WXApi.h"
#import "payRequsestHandler.h"
/**y銀聯支付*/

typedef void(^alipaySuccessBlock)();
typedef void(^alipayFailedBlock)();


@interface SKAliPayTool : NSObject
SKSingleH(SKAliPayTool)

/**支付寶支付*/

/**微信支付*/
- (void)gopayForWeChat;

/**綜合方法*/
- (void)goPayByPayType:(NSString *)payType andOrderNum:(NSString *)orderNum andTitle:(NSString *)title andDescribetion:(NSString *)describe andPrice:(NSString *)price;

/**訂單號*/
@property (nonatomic,copy) NSString *orderNum;
/**標題*/
@property (nonatomic,copy) NSString *title;
/**商品描述*/
@property (nonatomic,copy) NSString *describe;
/**付款價格*/

/**支付成功*/

支付成功直接調用： [SKAliPayTool sharedSKAliPayTool].paySuccess();
