iPhone – Capture Screenshot Programmatically

Capturing screenshot on iPhone needs the QuartzCore framework.

1. Right click the Framework folder in your Xcode project.

2. Add -< Add Existing Frameworks

3. Choose the QuartzCore.framework


4. Import the QuartzCore framework in the .h header file

#import <QuartzCore/QuartzCore.h>


5. Add the following few lines in the .m implementation file to capture the screenshot

// Capture Screenshot
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *screenshotImage = UIGraphicsGetImageFromCurrentImageContext();
UIImageWriteToSavedPhotosAlbum(screenshotImage, nil, nil, nil);


6. Try it

Done =)

    CurrentScreen.transform = CGAffineTransformMakeRotation(4.71238898);
    thats how i rotate my image


  3. I’m at Startup Weekend in LA right now where a few of the iPhone developers here have said that it’s impossible to take a screenshot programmatically between applications due to iOS sandbox restrictions but I’m not convinced of this. Two tutorials explain how to capture a screenshot programmatically when using a single application (see “Programmatically Getting a Screencapture of any UIView”, http://www.icodeblog.com/2009/07/27/1188/ and “iPhone – Capture Screenshot Programmatically”, https://ykyuen.wordpress.com/2010/04/10/iphone-capture-screenshot-programmatically/) but I am trying to figure out if a screenshot can be taken between one application and another like when a new text message comes in when the iPhone is not locked, and when it is.

    Any help will be appreciated…thanks.



  4. Hi Noah,

    Do you mean you want to take a screenshot and save it to the iphone album when
    1. The iPhone is unlocked
    2. The iPhone is locked
    3. When a sms is received

    if that is the case, i think you can refer to the following Q&A for the 1st and 2nd scenarios.
    StackOverflow – Lock Unlock events iphone

    For the third one, i think there should be some api to detect that. you can try to search on google.



  5. Thanks much for posting this.
    I just put it in my application, and got a great picture of everything BUT my navigation bar.
    Do you have any idea how to capture that as well?
