1、替代UIAlertView

代码：

 if(SYSTEM_VERSION >= 8.0)    {        UIAlertController * alertCtr = [UIAlertController alertControllerWithTitle:@"" message:@"删除联系人？" preferredStyle:UIAlertControllerStyleAlert];        UIAlertAction *firstAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {            //do something        }];        UIAlertAction *secondAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {            //do something        }];        [alertCtr addAction:firstAction];        [alertCtr addAction:secondAction];        [self presentViewController:alertCtr animated:YES completion:^{                    }];    }

2、替代UIActionSheet

代码：

 if(SYSTEM_VERSION >= 8.0)    {        UIAlertController * alertCtr = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];        UIAlertAction *firstAction = [UIAlertAction actionWithTitle:@"回复" style:UIAlertActionStyleDestructive handler:^(UIAlertAction *action) {            //do something        }];        UIAlertAction *secondAction = [UIAlertAction actionWithTitle:@"转发" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {            //do something        }];        UIAlertAction *thirdAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {            //do something        }];        [alertCtr addAction:firstAction];        [alertCtr addAction:secondAction];        [alertCtr addAction:thirdAction];        [self presentViewController:alertCtr animated:YES completion:^{                    }];    }
