Custom UISlider - Increase “hot spot” size

Resize frame and change image alignment to desired one. You can make its alignment centred, left, right, top or bottom. Make it this way:

CGRect newFrame = sliderHandle.frame;
CGRectSetWidth(newFrame, 80);
CGRectSetHeight(newFrame, 80);
[sliderHandle setFrame:newFrame];
[sliderHandle setContentMode:UIViewContentModeCenter];

So your touching frame will be bigger and image scale will remain unchanged.
