Taking screenshots in iOS

There are two ways to do this.
option 1 )
[sourcecode language=”objc”]
CGSize size = [self.view bounds].size;
[[self.view layer] renderInContext:UIGraphicsGetCurrentContext()];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
The above code is helpful when you have static uiviews.
Consider you have a many uiviews and you are moving them around with gestures. At this instant, if you use the above code, it will take a screenshot but only the original positions of the uiviews not the current positions of the uiviews.
For this you will need to the following. I got this code from the apple website.
[sourcecode language=”objc”]
#import <QuartzCore/QuartzCore.h>
– (UIImage*)screenshot
// 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);
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
// 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
-[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
// Retrieve the screenshot image
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
return image;
The above code will do the work for you.
