CGRect rect = [[UIScreen mainScreen] bounds];
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
[yourView.layer renderInContext:context];

试试这个来拍摄你的 screeShoT

-(UIImage*)getScreenShot
{
    CGSize screenSize = [[UIScreen mainScreen] applicationFrame].size;

    //CGSize screenSize = CGSizeMake(1024, 768);
    CGColorSpaceRef colorSpaceRef = CGColorSpaceCreateDeviceRGB();

    CGContextRef ctx = CGBitmapContextCreate(nil, screenSize.width, 416, 8, 4*(int)screenSize.width, colorSpaceRef, kCGImageAlphaPremultipliedLast);
    CGContextTranslateCTM(ctx, 0.0, screenSize.height);
    CGContextScaleCTM(ctx, 1.0, -1.0);

    [(CALayer*)self.yourView.layer renderInContext:ctx];

    CGImageRef cgImage = CGBitmapContextCreateImage(ctx);
    UIImage *image = [UIImage imageWithCGImage:cgImage];
    CGImageRelease(cgImage);
    CGContextRelease(ctx);

    return image;

}

这是我们如何做到：

UIGraphicsBeginImageContextWithOptions(yourView.bounds.size, yourView.opaque, 0.0);
[yourView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *LastImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
