UNIapp 自定义uni-picker 确定取消文字

在uni.css 里面加上这几行css就好了

.uni-picker-container .uni-picker-action.uni-picker-action-confirm{color:#fff!important;position:relative;}
.uni-picker-container .uni-picker-action.uni-picker-action-confirm:after{content:'Confirm';color:red;}
.uni-picker-container .uni-picker-action.uni-picker-action-cancel{color:#fff!important;position:relative;}
.uni-picker-container .uni-picker-action.uni-picker-action-cancel:before{content:'Cancel';color:#888;}
uni-actionsheet .uni-actionsheet__action .uni-actionsheet__cell{color:#fff!important}
.uni-actionsheet .uni-actionsheet__action .uni-actionsheet__cell::after{content:'Cancel';color:#000;position: absolute;left:50%;transform: translateX(-50%);}
