On iPhone, is there a way to tap a rounded rect button and take a screenshot, I don't want my users taking a photo by pressing sleep+home button! What are the code and frameworks needed?

Here's a Class method that will return a UIImage of the UIView and CGRect you pass to it:

+ (UIImage *)captureView:(UIView *)view withArea:(CGRect)screenRect {

    UIGraphicsBeginImageContext(screenRect.size);

    CGContextRef ctx = UIGraphicsGetCurrentContext();
    [[UIColor blackColor] set];
    CGContextFillRect(ctx, screenRect);

    [view.layer renderInContext:ctx];

    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    return newImage;
}

  • Can I add newImage to UIImage *pic = [UIImage imageNamed:@"newImage"]; in other function? And in what format is newImage? – wagashi Sep 20 '11 at 18:05
