Hello everyone this is Ghaith. In this lesson, we will see how we can start creating a new iOS application that uses the DJI SDK that we connect to and get feedback on the registration status as it is the most important step if you want to develop a fully integrated DJI mobile app. I got already my Xcode project is opened here and a simulator. Now if you initiate a new pod file and type inside it. put DJI SDK iOS since we will be using this SDK the DJI SDK in our project so we need to install it using Cocoapods so go ahead and create a new file project and place this line of code or this line here and then go to your terminal to your project and then type pod install wait a minute and then you will get your DJI SDK iOS integrated and installed in your project now to make sure that the SDK is working you have to import it in your ViewController and then build command build to see if the SDK is connecting are working correctly in your environment yeah so the build is actually succeeded now to communicate with the server DJI server we need a protocol which is called DJISDKManagerDelegate if you want your view controller to follow this protocol you have to import or follow these two functions I prefer putting them below the viewDidLoad function for the time being we will not be using this function just ignore it and we will just be depending on the result of this function which is it checking if we get back an error or not so now we have to create another function that says register app in this function here we will be calling the DJI SDK manager and saying register app on this view controller now if you check this function explanation it says the first time the app is initialized after installation the app connects to a DJI server through the internet to verify the application key where is the application key we dont have any application key yet we will be creating that in a few seconds after we finish our code so first lets call this function from the viewDidload here register app and after we call this register app function and the callback will be in here and then we will get the result of the calling and after the DJI server will check for us the DJI SDK app key if is not if it is matching correctly or not so we got the error now here we will type some logic define a new of our message and inside this message well say we will say register register app succeed maybe now if error is not equal to null what does that mean this means that if there is an error if we got an error then we change the message context to register app field, please enter your app key in the Plist file and check the network yeah else we could print out some statement that says for example register success now lets create another function that will show a pop-up message for us to show alert view for example with a with title uh for example lets say uh with title oh sorry we have here definition with title and insight title of type string and then with the message the inside message is also of type string and inside logic here is about defining an alert of type UI alert controller with the title the same title we pass here and miss a message the same message we pass here and the preferred style is alert and let for example ok action we need action here to close the pop-up message which is the UI alert action with a title for example okay and the style default and here just nil for the handler now we can add for the alert controller a new action which is ok action and then we can display this action on the screen we can say yeah of course the alert animated to true and completion is nil now now if you run this app as it is we should get the alert view function I will pop up an alert view with a without any success for the app key, yeah but here first we have to call it here with the message and yeah with message sorry the message should go here as the logic yeah and the title should be here, for example, lets say uh lets say the title is register app run again yeah so it says register app field please enter your app key in the Plist file and check the network so we dont have yet the, okay we will do that we dont have yet the uh DJI SDK app key here so we have to go to the website of the DJI you can get to the account.dgi.com and register a new developer account if you dont have one from here I already got my own so I will be creating a new app under the SDK mobile SDK and the app name, for example, lets say test you can type here whatever you want and choose ios where the bundle identifier should be the same as this app bundle identifier so you can get it from here I guess yeah so paste it here and then for the category you can choose whatever you want and here just type test create one so after youre creating it the DJI will send you an email that has the activation account or activation email that says just open it and you will be redirected to this page after as you can see here if I refresh I will get the app key so copy this app key and go to the info.plist and then just add this key under something called DJI SDK app key and put it here sorry I will do it again DJI SDK why Im getting s at the beginning DJI SDK app key and then passed past this string here yeah make sure to type all of this capital and then small double p and then the k is capital and then small e e y okay and place this key here and run again now the communication should be yeah done correctly register app is succeeded so this is the first lesson see you in the next one thank you
