Placement of fonts inside the IOS button

Button.contenthorizontalalignment = Uicontrolcontenthorizontalalignmentleft;

Button.titleedgeinsets = Uiedgeinsetsmake (0, 10, 0, 0);

First of all, use button.titleLabel.textAlignment = Nstextalignmentleft here; This line of code is not effective, it just makes the text in the label left-justified, but does not change the alignment of the label in the button.

So we use button.contenthorizontalalignment = Uicontrolcontenthorizontalalignmentleft;

This line of code, the content (control) of the button to modify the alignment to horizontal left-aligned, but this will be tightly to the left, not good-looking, so we can also modify the properties: Button.titleedgeinsets = Uiedgeinsetsmake (0, 10, 0, 0);

This line of code allows the button's contents (controls) to be 10 pixels from the left, which makes it much more attractive.
