  cgfloat top, left, bottom, right;//Specify amount to inset (positive) for each of the Edges. Values can be negative to ' outset '
} uiedgeinsets;

There are three sets of edgeinsets in UIButton: Contentedgeinsets, Titleedgeinsets, imageedgeinsets

@property (nonatomic)     uiedgeinsets contentedgeinsets ui_appearance_selector;//default is Uiedgeinsetszero
@ Property (nonatomic)     uiedgeinsets titleedgeinsets;        Default is Uiedgeinsetszero
@property (nonatomic)     BOOL     reversestitleshadowwhenhighlighted; Default is NO. If YES, shadow reverses to shift between engrave and emboss appearance
@property (nonatomic)     uiedgeinsets Imagee Dgeinsets;        Default is Uiedgeinsetszero

Uiedgeinsetsmake

The four parameters inside the
