Question

Is it possible to set an image over an other image,
respectively to overlay an image above an UIImage.

I give some code:

• Headerfile:

  @property (nonatomic,assign)UIImageView* imageView;
  

• Implementationfile

  UIImage *overlayImage = [UIImage imageNamed:@"lamp.png"];
  

---

The “imageView.image” has got an image and above that I will have this lamp, but later on it has to be possible to move it.

I searched some methods, but all methods gave me warnings.

Could you help me how to manage it? And is Core Animation an alternative to handle that?

Just add it as a subview. UIImageView is a UIView like any other.

UIImage *overlayImage = [UIImage imageNamed:@"lamp.png"];
UIImageView *overlayImageView = [[UIImageView alloc] initWithImage:overlayImage];
[self.imageView addSubview:overlayImageView];
