本文对比了UIAlertView和UIAlertController在实现弹窗功能时的区别与联系，包括使用方法、参数设置以及应用场景。

二者都可实现弹窗功能:
UIAlertView:

//用button触发
- (void)button{
    UIAlertView *alterView = [[UIAlertView alloc] initWithTitle:@"提示" message:@"网络不给力...." delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"继续",@"再试一次", nil];
    [alterView show];
}

效果图

UIAlertController

- (void)button{
    UIAlertController *controller = [UIAlertController alertControllerWithTitle:@"提示" message:@"网速不给力..." preferredStyle:(UIAlertControllerStyleAlert)];
    [self presentViewController:controller animated:YES completion:nil];
    UIAlertAction *action1 = [UIAlertAction actionWithTitle:@"取消" style:(UIAlertActionStyleCancel) handler:nil];
    UIAlertAction *action2 = [UIAlertAction actionWithTitle:@"继续" style:(UIAlertActionStyleDefault) handler:nil];
    UIAlertAction *action3 = [UIAlertAction actionWithTitle:@"再试一次" style:(UIAlertActionStyleDestructive) handler:nil];

    [controller addAction:action1];
    [controller addAction:action2];
    [controller addAction:action3];
}
