UIButton Content left

Sometimes we want UIButton's title to be left aligned, we set
Btn.textLabel.textAlignment = Uitextalignmentleft
is not useful, we need to set
Btn.contenthorizontalalignment = Uicontrolcontenthorizonalignmentleft;
Uicontrolcontenthorizontalalignmentleft
But the problem comes up and the text sticks to the border, and we can set the
Btn.contentedgeinsets = Uiedgeinsetsmake (0,10, 0, 0); The
keeps the text distance from a border of 10 pixels.
