1.下载支付宝SDK以及Demo
https://doc.open.alipay.com/doc2/detail?treeId=54&articleId=103419&docType=1
2.新建文件夹“AliSDK”，将压缩包内的文件拷贝到该文件夹下，完成后如下图所示：
3.将文件夹拷贝到项目中，
4.执行完第二步后项目目录里会出现蓝色的AliSDK分组。然后添加相应的库文件，添加完成后如下图所示：
5.拷贝完成后编译会出现如下错误：只需要在相应的类内添加：#import <Foundation/Foundation.h>即可解决
6.添加完成后编译仍然有错误：
解决办法：Targets->Build Settings->Header Search Path中添加1中建立的aliSDK文件夹的路径（找到alisdk路径拖拽到这儿就好了）：
此时问题解决了。
7.整理项目目录，把添加的库文件移动的framework分组内，ali也移动到framework分组内，如下所示：
8.新建Product类，Product.h内如下所示：
#import <Foundation/Foundation.h>
@interface Product : NSObject{
@private
float _price;
NSString *_subject;
NSString *_body;
NSString *_orderId;
}
@property (nonatomic, assign) float price;
@property (nonatomic, copy) NSString *subject;
@property (nonatomic, copy) NSString *body;
@property (nonatomic, copy) NSString *orderId;
@end9.viewController.h
#import "ViewController.h"
#import "Product.h"
#import "Order.h"
#import "AliSDK/Util/DataSigner.h"
#import <AlipaySDK/AlipaySDK.h>
@interface ViewController () @end @implementation ViewController - (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}

NSLog(@"reslut = %@",resultDic);
}]; } }

}
return resultStr;
} - (void)didReceiveMemoryWarning {

} @end
10.appdelegate.m中添加如下代码：
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation { if ([url.host isEqualToString:@"safepay"]) {
//跳转支付宝钱包进行支付，处理支付结果
[[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
NSLog(@"result = %@",resultDic);
}];
}
return YES;
} // NOTE: 9.0以后使用新API接口
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options
{
if ([url.host isEqualToString:@"safepay"]) {
//跳转支付宝钱包进行支付，处理支付结果
[[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
NSLog(@"result = %@",resultDic);
}];
}
return YES;
}
大功告成！！
