    代码：

    01.if(SYSTEM_VERSION >= 8.0)
    02.{
    03.UIAlertController * alertCtr = [UIAlertController alertControllerWithTitle:@"" message:@"删除联系人？" preferredStyle:UIAlertControllerStyleAlert];
    04.UIAlertAction *firstAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
    05.//do something
    06.}];
    07.UIAlertAction *secondAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
    08.//do something
    09.}];
    10.[alertCtr addAction:firstAction];
    11.[alertCtr addAction:secondAction];
    12.[self presentViewController:alertCtr animated:YES completion:^{
