- (IBAction)doClick:(UIButton *)sender {
UIAlertController * alertC = [UIAlertController alertControllerWithTitle:@"隨便按" message:@"讓你按你就按" preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction * action1 = [UIAlertAction actionWithTitle:@"選項(xiàng)1" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

- 該方法于iOS8推出剥悟，并代替
UIAlertView和UIActionSheet兩種方法缀拭，分別用創(chuàng)建時(shí)的preferredStyle來(lái)代表前兩種方法：UIAlertControllerStyleActionAlert涕癣、UIAlertControllerStyleActionSheet峻村。 - 對(duì)應(yīng)選項(xiàng)的響應(yīng)分別在UIAlertAction的block內(nèi)部實(shí)現(xiàn)谷遂。
