ios8不用于以前，uiAlertController属于UIViewController,而以前UIAlertView是属于UIView的。

//添加对话提示框

UIAlertController *actionSheetController = [UIAlertController alertControllerWithTitle:@"提示" message:@"请选择”"preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *actionCancel = [UIAlertAction actionWithTitle:@"确定"style:UIAlertActionStyleDestructivehandler:^(UIAlertAction * action) {}];

[actionSheetController addAction:actionCancel];

[actionSheetController.view setTintColor:[UIColor redColor]];

[self presentViewController:actionSheetController animated:YES completion:nil];

用法二---多选项

UIAlertController *actionSheetController = [UIAlertController alertControllerWithTitle:@"action选项" message:nilpreferredStyle:UIAlertControllerStyleActionSheet];

UIAlertAction *action0 = [UIAlertAction actionWithTitle:@"选项一" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {

[self customMethod1];

}];

[actionSheetController addAction:action0];

UIAlertAction *action = [UIAlertAction actionWithTitle:@"选项二" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {

[self <span style="font-family: Arial, Helvetica, sans-serif;">customMethod2</span>];

}];

UIAlertAction *action1 = [UIAlertAction actionWithTitle:@"选项三" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {

[self customMethod3];

}];
