ios - UIButton border disappears -


i'm designing new button app, i'd avoid coding have use same button style through app. added attributes , works fine, when add border color (doesn't matter color) no reason border disappears. going on? enter image description here

you can not set properties of view's layer through interface builder. can set layer's borderwidth , cornerradius via interface builder tool of xcode, not able set bordercolor using interface builder , it's because layer.bordercolor wants cgcolor instead of uicolor. , unfortunately, there's no way assign cgcolorref type in interface builder.

you can programmatically set button's border color on layer as-

[[button layer] setbordercolor:[uicolor redcolor].cgcolor];
