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 •WARNING Private API Usage! •Make sure none of this ships to the AppStore •Conditional Compile and perhaps use a new target
17. Modifying Your Code •Add KSScreenshotManager and KSScreenshotAction.h / .m to your project. #de ne CREATING_SCREENSHOTS
18. Modifying Your Code •Create a subclass of KSScreenshotManager •Override -(void)setupScreenshotActions;
19. setupScreenshotActions •Create instances of KSScreenshotAction •block-based API with optional cleanup blocks •synch or async, status bar or no [self addScreenshotAction:newAction];
20. KSScreenshotAction block •Get the app to the correct state •Cheat as necessary •Fake Data, Mock Objects, etc. •Private APIs, both app and OS
21. AppDelegate Changes #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
