    self.checkBoxButton.selected = isChecked;
    self.checkBoxButton.contentHorizontalAlignment = UIControlContentVerticalAlignmentFill;
    self.checkBoxButton.contentVerticalAlignment = UIControlContentVerticalAlignmentFill;
    self.checkBoxButton.imageView.contentMode = UIViewContentModeScaleAspectFit;

this is my tableview looks like

I would like my uibutton image be same size as the big ones.

when my view loads the sizes of images is fine..however when i begin the touch of button the images begin to collapse, it even put the big ones smaller and smaller ones bigger randomly.

Per update

Looks to me like the button isn't set to UIButtonTypeCustom and the system is somehow adjusting it on the touch began event. Try changing the button type to custom.

In the cellForRowAtIndexPath delegate method, after you dequeue a reusable cell, try resetting the checkbox to either nil or its default image, or try forcing its BOOL value to false. Once you've reset the image, then try calling the method (not setting the property) for selected:

BOOL isChecked = [model.isChecked boolValue];
[self.checkBoxButton setSelected:isChecked];

My vague guess to what's going on here is that somehow the value from the model is being retrieved before the cell is dequeued, and thus it retains some value from the last time the cell was used. If you clear it out after dequeuing, then set the value from the model, it should set it correctly.
