AWSS3PreSignedURLBuilder

Objective-C

@interface AWSS3PreSignedURLBuilder : AWSService

/**
 Returns the singleton service client. If the singleton object does not exist, the SDK instantiates the default service client with `defaultServiceConfiguration` from `[AWSServiceManager defaultServiceManager]`. The reference to this object is maintained by the SDK, and you do not need to retain it manually.

 For example, set the default service configuration in `- application:didFinishLaunchingWithOptions:`

 *Swift*

     func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
         let credentialProvider = AWSCognitoCredentialsProvider(regionType: .USEast1, identityPoolId: "YourIdentityPoolId")
         let configuration = AWSServiceConfiguration(region: .USEast1, credentialsProvider: credentialProvider)
         AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = configuration

         return true
     }

 *Objective-C*

     - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
          AWSCognitoCredentialsProvider *credentialsProvider = [[AWSCognitoCredentialsProvider alloc] initWithRegionType:AWSRegionUSEast1
                                                                                                          identityPoolId:@"YourIdentityPoolId"];
          AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionUSEast1
                                                                               credentialsProvider:credentialsProvider];
          [AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;

          return YES;
      }

 Then call the following to get the default service client:

 *Swift*

     let S3PreSignedURLBuilder = AWSS3PreSignedURLBuilder.defaultS3PreSignedURLBuilder()

 *Objective-C*

     AWSS3PreSignedURLBuilder *S3PreSignedURLBuilder = [AWSS3PreSignedURLBuilder defaultS3PreSignedURLBuilder];

 @return The default service client.
