Programmatically create UIButtons on CircleImage

Question

I need to create Arch shaped UIButtons, on a circle image.(the O/p need to look like Concentric Circles),

At present I am using 5 images, but in future I may add some more Images, Dynamically I need to fil the circle Image with the added images.

I had a sample Piece of code and O/P is the below image

int numberOfSections = 6;
    CGFloat angleSize = 2*M_PI/numberOfSections;
 for (int j = 0; j < numberOfSections; ++j) {
        UIButton *sectionLabel = [[UIButton alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 150.0f, 2.0f)];
sectionLabel.backgroundColor = [UIColor redColor];
 sectionLabel.layer.anchorPoint = CGPointMake(1.0f, 0.5f);
        sectionLabel.layer.position = CGPointMake(container.bounds.size.width/2.0, container.bounds.size.height/2.0); // places anchorPoint of each label directly in the center of the circle.
        sectionLabel.transform = CGAffineTransformMakeRotation(angleSize*j);
        [container addSubview:sectionLabel];
    }

I have tried with this piece of code and the O/P is the below image

 int numberOfSections = 5;
    CGFloat angleSize = 2*M_PI/numberOfSections;
    for (int j = 0; j<numberOfSections; ++j) {
        UIImage *imageframe = [imagesArray objectAtIndex:j];
OBShapedButton *button = [[OBShapedButton alloc] initWithFrame:CGRectMake(0.0f, 150.0f, 150.0f, 128.0f)];
button.transform = CGAffineTransformMakeRotation(angleSize*j);
[container addSubview:button];
}

I need my output as the below image

How can i Achieve that

O/P after I Tried with Sarah Zuo's code

same width and height buttons
AnyKind of Help is more Appreciated

Answer 1

I can answer only last part,

If you are able to get images for buttons, then you can refer this tutorial. This might help you. Provided, your image formed is having transparent background.

Answer 2

If all buttons' image look like the one (same direction), the transform value may be work.

button.transform = CGAffineTransformMakeRotation(2*M_PI-angleSize*j);
button.center = CGPointMake(radius + radius * sin(angleSize * j) / 2, radius +  radius * cos(angleSize * j) / 2);

Answer 3

You can use your UIImageView instead. You can give different tag to image view and add Gesture Recognizer. Now you can get touch events like button click event on image views.
