iOS SDK
You can use Nearpay Connect in your IOS app
- 1.
2. Import the framework into your projects
Steps:
- In the project navigator, select your project.
- Select your target.
- Select the "General" tab.
- Open "Framework , Libraries and Embedded Content" expander.
- Click the + button.
- Add file
- (optional) or you can just drag and drop the file to "Framework , Libraries and Embedded Content".
3. Add bluetooth as "Bluetooth Always Usage Description" to your info.
4. import NearpayConnectKit
import NearpayConnectKit
5. Define connectivity object
@StateObject var conn: Connectivity = Connectivity.shared
6. add this modifier in the end of root view
.nearpayConnectivity()
7. Add sessionDelegate in main root
.onAppear {
conn.sessionDelegate = self
}
8. Start Purchase
conn.startPurchaseTransaction(amount: 300)
9. Add extension to root view
extension ContentView: TransactionSessionDelegate
{
func transactionSesison(didReciviedDataFor transaction: NearpayConnectKit.RemoteTransaction?, withError error: Error?) {
print("data received \(transaction)")
}
func transactionSession(didEndWithFor transaction: NearpayConnectKit.RemoteTransaction?, withError error: Error?) {
print("data error \(error)")
}
}
This function is used to show the setupUI of Nearpay connect
conn.setupUI()
Purchase is used to send the amount to the other Device
conn.startPurchaseTransaction(amount: 300)
Reset setting is used to reset all the settings .
conn.resetSetting()
ShowUI is a Boolean to check if UI is opened or closed.
var uiStatus = conn.showUI // it will be true or false
Please check the example
