我为您提供了手动解决方案。但我认为这不是一个好的解决方案:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Added to Cart" message:@"Some items are added for time being!" delegate:self cancelButtonTitle:@"View Cart" otherButtonTitles:@"", nil];

    UILabel *buttonTitle = [[UILabel alloc] initWithFrame:CGRectMake(148, 102, 125, 40)];
    buttonTitle.text = @"Continue Shopping";
    buttonTitle.font = [UIFont boldSystemFontOfSize:15];
    buttonTitle.textColor = [UIColor whiteColor];
    buttonTitle.textAlignment = UITextAlignmentCenter;
    buttonTitle.backgroundColor = [UIColor clearColor];
    buttonTitle.numberOfLines = 2;
    [alert addSubview:buttonTitle];
    alert.tag = 20;
    [buttonTitle release];
    [alert show];

无论如何你都可以使用它......
