Examples
Here are some code examples illustrating the usage of the ADAL iOS SDK:
// Import ADAL iOS SDK
@import ADAL;
// Create an instance of the ADAuthenticationContext class
ADAuthenticationContext *authContext = [[ADAuthenticationContext alloc] initWithAuthority:@"https://login.microsoftonline.com/common"
error:&error];
// Set the authentication context's client ID
[authContext setClientId:@"YOUR_CLIENT_ID"];
// Acquire an access token
[authContext acquireTokenWithResource:@"https://graph.microsoft.com"
clientId:@"YOUR_CLIENT_ID"
redirectUri:[NSURL URLWithString:@"YOUR_REDIRECT_URI"]
promptBehavior:AD_PROMPT_ALWAYS
userId:nil
extraQueryParameters:nil
completionBlock:^(ADAuthenticationResult *result) {
if (result.status == AD_SUCCEEDED) {
// Use the obtained access token to authenticate requests
NSLog(@"Access token: %@", result.accessToken);
} else {
// Handle error
NSLog(@"Error: %@", result.error.errorDetails);
}
}];
