/**
|
Entry point for using VK sdk. Should be initialized at application start.
|
|
Typical scenario of using SDK is next:
|
|
1) Register new standalone application on https://vk.com/editapp?act=create
|
|
2) Setup your application delegate and Info.plist as described on project page: https://github.com/VKCOM/vk-ios-sdk#how-to-set-up-vk-ios-sdk
|
|
3) Initialize SDK with your VK application ID.
|
|
VKSdk *sdkInstance = [VKSdk initializeWithAppId:VK_APP_ID];
|
|
4) Register required SDK-delegates (VKSdkDelegate) and single UI-delegate (VKSdkUIDelegate).
|
|
[sdkInstance registerDelegate:self];
|
[sdkInstance setUiDelegate:self];
|
|
5) Check if user already authorized.
|
|
[VKSdk wakeUpSession:SCOPE completeBlock:^(VKAuthorizationState state, NSError *error) {
|
switch (state) {
|
case VKAuthorizationAuthorized:
|
// User already autorized, and session is correct
|
break;
|
|
case VKAuthorizationInitialized:
|
// User not yet authorized, proceed to next step
|
break;
|
|
default:
|
// Probably, network error occured, try call +[VKSdk wakeUpSession:completeBlock:] later
|
break;
|
}
|
}];
|
|
6) If user is not authorized, call +[VKSdk authorize:] method with required scope (permission for token you required).
|
|
[VKSdk authorize:@[VK_PER_FRIENDS, VK_PER_WALL]];
|
|
7) You wait for -[VKSdkDelegate vkSdkAccessAuthorizationFinishedWithResult:] method called.
|
|
- (void)vkSdkAccessAuthorizationFinishedWithResult:(VKAuthorizationResult *)result {
|
if (result.token) {
|
// User successfully authorized, you may start working with VK API
|
} else if (result.error) {
|
// User canceled authorization, or occured unresolving networking error. Reset your UI to initial state and try authorize user later
|
}
|
}
