Introduction

To search for any resource in user’s Personal Cloud Storage account, call search:withCompletionHandler: method.

1. If you have not done that already, add Cloud SDK framework for IOS to an existing or a new IOS application.
2. Include VerizonCloudAPI.framework header file in you class: #import <VerizonCloudAPI/VerizonCloudAPI.h>
3. Initalize the PCSearchAPIParams and provide the required parameter. If the required parameter is not provided, the API call results in NSInvalidArgumentException exception.
4. Initalize the PCAPISDK object and call the search:withCompletionHandler: method.
5. Perform the search:withCompletionHandler: API call using the code sample in this example.
6. If the session is no longer valid:
   1. Call the logout API which the removes the access token stored in the keychain.
   2. Call authenticate:fromViewController:withCompletionHandler: API to get a new access token.

Examples

The following examples provide code samples that allow you to easily search for any resource.

Search for Files

This code sample returns all files sorted by name and displayed in ascending order.

Code Sample

@try {
PCSearchAPIParams *searchParams = [[PCSearchAPIParams alloc] init];

[[PCAPISDK sharedInstance] search:searchParams withCompletionHandler:^(NSArray *results, PCAPIQueryResponse *response){
switch (response.urlResponse.statusCode) {
case PCAPIResponseCodeOK:
case PCAPIResponseCodePreconditionFailed: {
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void) {

NSMutableArray *searchResult = [NSMutableArray new];

for (NSManagedObjectID *objID in results) {
PCResource *resource = [[PCResource alloc] initWithDBResourceID:objID];
NSLog(@"name: %@",resource.name);
[searchResult addObject:resource];
}

});
NSLog(@"Return list of file.");
