1、监听系统截屏通知
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleUserDidTakeScreenshotNotification:) name:UIApplicationUserDidTakeScreenshotNotification object:nil];
2、监听到截屏后获取屏幕截屏图片
UIWindow *window = [[[UIApplication sharedApplication] delegate] window]; // 1.开启上下文 UIGraphicsBeginImageContextWithOptions(window.bounds.size, window.opaque, 0); // 2.渲染 [window drawViewHierarchyInRect:window.bounds afterScreenUpdates:NO]; // 3.获取图片 UIImage *snapshotImage=UIGraphicsGetImageFromCurrentImageContext(); // 4.结束上下文 UIGraphicsEndImageContext();
3、对图片进行存储本地或者服务器进行分享操作
