iOS中系统基础的弹窗主要有两种样式：UIAlertControllerStyleAlert 与 UIAlertControllerStyleActionSheet。
Android中系统基本的弹出样式有：按钮positiveButton与negativeButton, setSingleChoiceItems单选框，setMultiChoiceItems多选框以及setProgressStyle进度样式的弹窗。当然、吐司(Toast)也算是Android中比较经典的弹窗了。

//UIAlertActionStyleDefault 默认的style
UIAlertAction *enter = [UIAlertAction actionWithTitle:@"enter" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
NSLog(@"这里是点击enter后的回调");
}];
//UIAlertActionStyleDestructive 会出现红色字体，用于提示操作 例如删除等
UIAlertAction *back = [UIAlertAction actionWithTitle:@"back" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action) {

}];
//UIAlertActionStyleCancel 取消操作的style
