iOS--支付宝环境集成

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{
@privatefloat     _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;@end

9.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.
}

}@end

10.appdelegate.m中添加如下代码：

- (BOOL)application:(UIApplication *)applicationopenURL:(NSURL *)urlsourceApplication:(NSString *)sourceApplicationannotation:(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;
}
