欢迎使用京东云开发者 iOS 工具套件（使用 Objective-C 语言编写）。使用京东云 iOS SDK，您无需复杂编程就可以访问京东云提供的各种服务。
为了方便您理解SDK中的一些概念和参数的含义，使用SDK前建议您先查看OpenAPI使用入门。要了解每个API的具体参数和含义，请参考程序注释或参考OpenAPI&SDK下具体产品线的API文档。
目前没有上传 pod 因此请手动引用源码到您的项目中进行编译。
关于使用方法请查看项目的JDCloudOCSDKVmTests 文件夹下的JDCloudOCSDKVmTests.m 文件 ，简单的调用示例如下：
Objective-C
-(void)testRequestSync{
/// init Credential
Credential * credential = [[Credential alloc]initWithAccessKeyId:@"your jdcloud ak" secretAccessKey:@"your jdcloud sk"];
/// if use internal service create this object and set client sdkEnvironment property
SDKEnvironment* sdkEnvironment = [[SDKEnvironment alloc]initWithEndPoint:@"apigw-internal.cn-north-1.jcloudcs.com"];
/// init client if use default environment please write like this "VmClient* vmClient = [[VmClient alloc] initWithCredential:credential]"
VmClient* vmClient = [[VmClient alloc] initWithCredential:credential sdkEnvironment:sdkEnvironment];
/// if set debug true it will write debug log
[GlobalConfig setDebug:true];
// set httpRequestProtocol if use internal set http else do not need to set this property , default value is https
vmClient.httpRequestProtocol = @"http";
// create request param
VmDescribeInstancesRequest* describeInstancesRequest = [[VmDescribeInstancesRequest alloc]initWithRegion:@"cn-north-1"];
// call sync method , if you want call async method see "JDCloudOCSDKVmTests/JDCloudOCSDKVmTests.m"
NSDictionary* result = [vmClient describeInstancesSyncWithRequest:describeInstancesRequest];
//get response data, the result key please see client notice
VmDescribeInstancesResponse* response = [result objectForKey:@"describeInstancesResponse"];
NSLog(@"总条数为：%@",[[response result] totalCount]);
}
[vmClient addCustomerHeaderWithKey:@"x-jdcloud-security-token" value:@"xxx"]
Credential * credential = [[Credential alloc]initWithAccessKeyId:@"ak" secretAccessKey:@"sk"];
// set request host
SDKEnvironment* sdkEnvironment = [[SDKEnvironment alloc]initWithEndPoint:@"apigw-internal.cn-north-1.jcloudcs.com"];
VmClient* vmClient = [[VmClient alloc] initWithCredential:credential sdkEnvironment:sdkEnvironment];
[GlobalConfig setDebug:true];
VmDescribeInstancesRequest* describeInstancesRequest = [[VmDescribeInstancesRequest alloc]initWithRegion:@"cn-north-1"];
vmClient.httpRequestProtocol = @"http";
dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);
[vmClient describeInstancesAsyncWithRequest:describeInstancesRequest completionHandler:^(int statusCode, VmDescribeInstancesResponse * _Nullable describeInstancesResponse, NSData * _Nullable responseData, NSError * _Nullable error) {
NSLog(@"总条数为：%@",[[describeInstancesResponse result] totalCount]);
dispatch_semaphore_signal(semaphore);
}];
dispatch_semaphore_wait(semaphore, DISPATCH_TIME_FOREVER);
