Question

I want to display an image in iPhone application on the whole screen but with a semi curve shape.
The image should start from the corner touching and ends on touching the another corner. I don't have an idea to make this can anyone help me please.
This image table is semi curved but image should be displayed on semi curved shape

Changing the image to be curvical or playing with images can be achieved Using CALayer. Every imageView has a layer over it. Use it to show the effect. The effect you wanted on your table image can be acheived through this code:-
-(void) viewDidLoad{
[self paperCurlShadowImage];
}
-(void) paperCurlShadowImage{
imgView = [[UIImageView alloc] initWithImage:image];
imgView.frame=CGRectMake(0, 0, image.size.width, image.size.height);
[self.view addSubview:imgView];
imgView.layer.shadowColor = [UIColor blackColor].CGColor;
imgView.layer.shadowOpacity = 0.7f;
imgView.layer.shadowOffset = CGSizeMake(10.0f, 10.0f);
imgView.layer.shadowRadius = 2.0f;
imgView.layer.masksToBounds = NO;
imgView.layer.shadowPath = [self renderPaperCurl:imgView];
[imgView release];
}
- (CGPathRef)renderPaperCurl:(UIView*)imgView1 {
CGSize size = imgView1.bounds.size;
CGFloat curlFactor = 15.0f;
CGFloat shadowDepth = 5.0f;
UIBezierPath *path = [UIBezierPath bezierPath];
[path moveToPoint:CGPointMake(0.0f, 0.0f)];
[path addLineToPoint:CGPointMake(size.width, 0.0f)];
[path addLineToPoint:CGPointMake(size.width, size.height + shadowDepth)];
[path addCurveToPoint:CGPointMake(0.0f, size.height + shadowDepth)
controlPoint1:CGPointMake(size.width - curlFactor, size.height + shadowDepth - curlFactor)
controlPoint2:CGPointMake(curlFactor, size.height + shadowDepth - curlFactor)];
return path.CGPath;
}
