Extending your SciChart Trial

If you have requested a trial extension from us, you will get the KeyCode that must be set in your app once, and once only before any SciChartSurface instance is shown.

For iOS: do this by calling the static SciChartSurface.SetRuntimeLicenseKey() method in AppDelegate.

Code samples below:

Swift

//
//  AppDelegate.swift
//  SciChartSwiftDemo
//
 
import UIKit
import SciChart

@UIApplicationMain

class SCSAppDelegate: UIResponder, UIApplicationDelegate {

 var window: UIWindow?

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        // Note! This is just an example. 
        // The real License KeyCode is found by following steps above
        SCIChartSurface.setRuntimeLicenseKey("YOUR_KEYCODE")
 
        return true
 }

}

Objective-C

//
//  AppDelegate.m
//  SciChartDemo
//
 
#import "AppDelegate.h"
#import "SCDConstants.h"
 
// NOTE: Import SciChart.h 
#import <SciChart/SciChart.h> 
 
@interface AppDelegate ()
 
@end
 
@implementation AppDelegate
 
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
     
    // Note! This is just an example. 
    // The real License KeyCode is found by following steps above
    [SCIChartSurface setRuntimeLicenseKey:@"YOUR_KEYCODE"];
     
    //...    
    return YES;
}
 
@end
