14. KSScreenshotManager
    •Make your code generate the screenshots
    •Fully-Automated
    •Runnable from scripting environments
    •Sample Python Script included
    •Uses “WaxSim” to drive the iOS Simulator

15. Like Test Automation
    •Not “For Free”
    •Cheaper to repeat over time
    •Effort scales more slowly than manual
    screenshots

16. Modifying Your Code

    target

    #if CREATING_SCREENSHOTS
    dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.0 *
    NSEC_PER_SEC));
    dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
    MyScreenshotManager *screenshotManager = [[MyScreenshotManager alloc]
    init];
    [screenshotManager setTableViewController:viewController];
    [screenshotManager takeScreenshots];
    });
    #endif
