封装第三方支付（支付宝、银联、微信支付）
今天对第三方支付做了一个小小的封装，框架的导入与配置这里就不多说了，可以去看集成文档。直接上封装的demo
使用方式：[[SKAliPayTool sharedSKAliPayTool] goPayByPayType:payName
andOrderNum:self.orderNumber
andTitle:self.orderNumber
andDescribetion:@"测试"
andPrice:[self.goodsDictionary safeJsonObjForKey:@"FactPrice"]];
[SKAliPayTool sharedSKAliPayTool].paySuccess = ^{
};
[SKAliPayTool sharedSKAliPayTool].payFailed = ^{
};
首先.h文件
#import <Foundation/Foundation.h>
#import "SKSingle.h"
/**支付宝*/
#import <AlipaySDK/AlipaySDK.h>
#import "Order.h"
#import "DataSigner.h"
/**微信支付*/
#import "WXApi.h"
#import "payRequsestHandler.h"
/**y银联支付*/
#import "UPPaymentControl.h"
typedef void(^alipaySuccessBlock)();
typedef void(^alipayFailedBlock)();
@interface SKAliPayTool : NSObject
SKSingleH(SKAliPayTool)
/**支付宝支付*/
- (void)gopayForAli;
/**微信支付*/
- (void)gopayForWeChat;
/**综合方法*/
- (void)goPayByPayType:(NSString *)payType andOrderNum:(NSString *)orderNum andTitle:(NSString *)title andDescribetion:(NSString *)describe andPrice:(NSString *)price;
/**订单号*/
@property (nonatomic,copy) NSString *orderNum;
/**标题*/
@property (nonatomic,copy) NSString *title;
/**商品描述*/
@property (nonatomic,copy) NSString *describe;
/**付款价格*/
@property (nonatomic,copy) NSString *totalPrice;
/**支付成功*/
@property (nonatomic,copy) alipaySuccessBlock paySuccess;
@property (nonatomic,copy) alipayFailedBlock payFailed;
@end
