I'm using this method to take a screenshot of my app:
+ (NSData*)TakeScreenshot { // Create a graphics context with the target size // On iOS 4 and later, use UIGraphicsBeginImageContextWithOptions to take the scale into consideration // On iOS prior to 4, fall back to use UIGraphicsBeginImageContext CGSize imageSize = [[UIScreen mainScreen]bounds].size; if (NULL != UIGraphicsBeginImageContextWithOptions) UIGraphicsBeginImageContextWithOptions(imageSize, NO, 0); else UIGraphicsBeginImageContext(imageSize); CGContextRef context = UIGraphicsGetCurrentContext(); // Iterate over every window from back to front for (UIWindow *window in [[UIApplication sharedApplication] windows]) { if (![window respondsToSelector:@selector(screen)] || [window screen] == [UIScreen mainScreen]) { // -renderInContext: renders in the coordinate space of the layer, // so we must first apply the layer's geometry to the graphics context CGContextSaveGState(context); // Center the context around the window's anchor point CGContextTranslateCTM(context, [window center].x, [window center].y); // Apply the window's transform about the anchor point CGContextConcatCTM(context, [window transform]); // Offset by the portion of the bounds left of and above the anchor point CGContextTranslateCTM(context, -[window bounds].size.width * [[window layer] anchorPoint].x, -[window bounds].size.height * [[window layer] anchorPoint].y); // Render the layer hierarchy to the current context [[window layer] renderInContext:context]; // Restore the context CGContextRestoreGState(context); } } // Retrieve the screenshot image UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); NSData *imageData = UIImageJPEGRepresentation(image, 100); UIGraphicsEndImageContext(); return imageData;}The problem is, I don't see the status bar. I'm getting only a white area without the status bar. How can I take a screenshot of the whole screen, with the status bar and other controls like tabbar, navigation bar and etc.
Thanks in advance!
