How to make collage of images according to different shapes [closed]

Answer 1

I just put my logic.

• your view has been display 4 images (with different shape) so you need to take 4 UIImageView in .h file and one UIView name is ImgContainerView in .h file

• make sure that your all button has same action method and give all button to it's tag. for example each button has method name is

  -(void) buttonMethodName:(UIButton *) sender

• Then you need to create one method name is,

  -(void)setUpimagesByselectedButton:(int) buttonTag

Call this method in button's action method, such like

-(void) buttonMethodName:(UIButton *) sender           
{
  [self setUpimagesByselectedButton:sender.tag]; // pass button's tag as parameter.
}

Here now in method,

-(void)setUpimagesByselectedButton:(int) buttonTag
{
  // first you need to remove all subview of ImgContainerView 
  if(self.ImgContainerView)
  {
    for(UIView *subview in self.ImgContainerView.subviews)
        [subview removeFromSuperview];
    [self.ImgContainerView removeFromSuperview]; self.ImgContainerView = nil;
  }
  // Then re-create  ImgContainerView with background color is white;
  // add all UIImageView as subView of ImgContainerView;
  // and then set FRAME of your UIImageView base on selected button's tag such like.
  if(buttonTag == 1)// for ex. i take 1, here you write your button's tag.
    self.imageView1.frame....
  // create one by one imageView and set it's frame by put condition as above       
  // your UIImageView's contentMode should be  UIViewContentModeScaleAspectFill or UIViewContentModeCenter;
}

When you tap any button then each time ImgContainerView is re-created with it's particular shape.
