我试图列出许多 UISegmentControls 的选定索引。我分别在1、2、3、4、5上设置了5个，使用这段代码后的结果（在数组中）是：2、2、0、0、0...

for (UISegmentedControl *seg in segmentArray)
{
    NSString* xWrapped = [NSString stringWithFormat:@"%d", seg.selectedSegmentIndex+1];
    [difficultyH addObject: xWrapped];
}

为什么？？

编辑：

这是创建细分的方式：

//segment controll

            NSArray *itemArray2 = [NSArray arrayWithObjects: @"very easy", @"easy", @"ok", @"hard", @"challenging", nil];
            UISegmentedControl *segmentedControl2 = [[UISegmentedControl alloc] initWithItems:itemArray2];
            segmentedControl2.frame = CGRectMake(480, -60, 130, 350);
            segmentedControl2.segmentedControlStyle = UISegmentedControlStyleBar;
            segmentedControl2.selectedSegmentIndex = val - 1;
            [segmentedControl2 addTarget:self action:@selector(segmentedControlHomework:) forControlEvents:UIControlEventValueChanged];

            segmentedControl2.transform =
            CGAffineTransformRotate(segmentedControl2.transform, degreesToRadians(90));

            NSArray *arr = [segmentedControl2 subviews];
            for (int i = 0; i < [arr count]; i++) {
                UIView *v = (UIView*) [arr objectAtIndex:i];
                NSArray *subarr = [v subviews];
                for (int j = 0; j < [subarr count]; j++) {
                    if ([[subarr objectAtIndex:j] isKindOfClass:[UILabel class]]) {
                        UILabel *l = (UILabel*) [subarr objectAtIndex:j];
                        l.transform = CGAffineTransformMakeRotation(- M_PI / 2.0); //do the reverse of what Ben did
                    }
                }
            }

            [image1 addSubview:segmentedControl2];

            segmentedControl2.tag = i;

            [segmentArray addObject: segmentedControl2];

            //segment controll
