Six definitions of button types:

Uibuttontypecustom = 0, no type

Uibuttontyperoundedrect, Four corners are arc shaped

Uibuttontypedetaildisclosure

Uibuttontypeinfolight

Uibuttontypeinfodark

Uibuttontypecontactadd

Forstate setting the state of the button before and after clicking

Click before you click

uicontrolstatehighlighted

uicontrolstateselected

Uicontrolstatedisabled

UIControlStateNormal

Uibuttontyperoundedrect is set to this property, is to meet our normal situation of the button fillet, when we add a background image and background color on the button, we will find that this property does not apply, because the button is now not rounded corners, It shows the shape of the picture, and it can be displayed when the setting background color is set to the Uibuttontypecustom property. So we need to use the other properties of the UIButton control to meet our needs.

UIButton *btn;    [Btn.layer Setmaskstobounds:yes];    [Btn.layer setcornerradius:10.0];//Set Rectangle four fillet radius/        *        [btn.layer setborderwidth:1.0];//Border Width     */
