UIScrollView不滚动iOS

我试图在一个视图中创建几个UIScrollView，这些视图在iOS中水平滚动。这是我目前的代码：

-(void)updateSection {
    [feedLoadingActInd stopAnimating];
    feedLoadingActInd.hidden = YES;
    builder = [NSMutableArray array];
    float xPosition = 0;
    float xPosBut = 0;

    scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 400, self.frame.size.width, self.frame.size.height - 29)];
    [scrollView setScrollEnabled:YES];
    scrollView.backgroundColor = [UIColor yellowColor];

    scrollView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    scrollView.pagingEnabled = YES;
    scrollView.delegate = self;

    for (int i = 0; i < itemArticleArray.count; i++) {
        testButton = [[UIButton alloc] initWithFrame:CGRectMake(xPosBut, 40, 40, 40)];
        [testButton setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];
        [testButton setTitle:@"Test" forState:UIControlStateNormal];
        [testButton addTarget:self action:@selector(buttonPressed) forControlEvents:UIControlEventTouchUpInside];
        testButton.backgroundColor = [UIColor blueColor];
        xPosBut += testButton.frame.size.width;
        NSLog(@"scroll.frame.size.width = %f", scrollView.frame.size.width);

        xPosition += 2;
        UIView *seperatorView = [[UIView alloc] initWithFrame:CGRectMake(xPosition, 4, 350, scrollView.frame.size.height - 8)];
        seperatorView.backgroundColor = [UIColor redColor];
        [scrollView addSubview:seperatorView];
        xPosition += 350;

        [seperatorView addSubview:testButton];
        [scrollView addSubview:seperatorView];
        [builder addObject:testButton];

    }
    [self addSubview:scrollView];
    [scrollView setUserInteractionEnabled:YES];
    [scrollView setContentSize: CGSizeMake(xPosition, scrollView.frame.size.height)];

    NSLog(@"scroll.contentsize.width = %f", scrollView.contentSize.width);

-（void）updateSection{
[FeedLoadingActin and Stop Animating]；
feedLoadingActInd.hidden=是；
生成器=[NSMutableArray]；
浮点xPosition=0；
float xPosBut=0；
scrollView=[[UIScrollView alloc]initWithFrame:CGRectMake（0400，self.frame.size.width，self.frame.size.height-29）]；
[滚动视图设置可滚动：是]；
scrollView.backgroundColor=[UIColor yellowColor]；
scrollView.autoresizingMask=UIViewAutoresizingFlexibleWidth | UIViewAutoResizingFlexibleHight；
scrollView.PaginEnabled=是；
scrollView.delegate=self；
对于（int i=0；i[scrollView setContentSize:CGSizeMake（xPosition，scrollView.frame.size.height）]；
NSLog（@“scroll.contentsize.width=%f”，scrollView.contentsize.width）；

}

然而，没有一个滚动视图实际上是滚动的，我对此感到困惑，因为添加了多个按钮。另外，我添加的按钮在我按下时实际上没有任何作用。他们应该运行buttonPressed方法，但它没有

任何帮助都将不胜感激

试试这个

float xPosition = 0;
    float xPosBut = 0;

    scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 100,self.view.frame.size.width, self.view.frame.size.height - 29)];
    [scrollView setScrollEnabled:YES];

    scrollView.backgroundColor = [UIColor yellowColor];

    for (int i = 0; i < 10; i++) {
       UIButton *testButton = [[UIButton alloc] initWithFrame:CGRectMake(xPosition, 10, scrollView.frame.size.width, 50)];
        [testButton setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];
        [testButton setTitle:@"Test" forState:UIControlStateNormal];
        [testButton addTarget:self action:@selector(buttonPressed) forControlEvents:UIControlEventTouchUpInside];
        testButton.backgroundColor = [UIColor blueColor];
        xPosition += testButton.frame.size.width;
        NSLog(@"xposbut = %f", xPosBut);
        NSLog(@"scroll.frame.size.width = %f", scrollView.frame.size.width);

        xPosition += scrollView.frame.size.width+2;
        UIView *seperatorView = [[UIView alloc] initWithFrame:CGRectMake(xPosition, 4, 2, scrollView.frame.size.height - 8)];
        seperatorView.backgroundColor = [UIColor redColor];
        [scrollView addSubview:seperatorView];
        xPosition +=scrollView.frame.size.width+ 4;

        [self.view addSubview:scrollView];
        [scrollView addSubview:seperatorView];
        [scrollView addSubview:testButton];
        [builder addObject:testButton];

    }
    [scrollView setContentSize: CGSizeMake(xPosition, scrollView.frame.size.height)];
    [self.view addSubview:scrollView];

float xPosition=0；
float xPosBut=0；
scrollView=[[UIScrollView alloc]initWithFrame:CGRectMake（0,100，self.view.frame.size.width，self.view.frame.size.height-29）]；
[滚动视图设置可滚动：是]；
scrollView.backgroundColor=[UIColor yellowColor]；
对于（int i=0；i<10；i++）{
UIButton*testButton=[[UIButton alloc]initWithFrame:CGRectMake（xPosition，10，scrollView.frame.size.width，50）]；
[testButton setTitleColor:[UIColor greenColor]用于状态：UIControlStateNormal]；
[testButton setTitle:@“测试”状态：UIControlStateNormal]；
[testButton addTarget:self action:@selector（按钮按下）for ControlEvents:UIControlEventTouchUpInside]；
testButton.backgroundColor=[UIColor blueColor]；
xPosition+=testButton.frame.size.width；
NSLog（@“xposbut=%f”，xposbut）；
NSLog（@“scroll.frame.size.width=%f”，scrollView.frame.size.width）；
xPosition+=scrollView.frame.size.width+2；
UIView*separatorview=[[UIView alloc]initWithFrame:CGRectMake（xPosition，4,2，scrollView.frame.size.height-8）]；
separatorview.backgroundColor=[UIColor redColor]；
[滚动视图添加子视图：分隔视图]；
xPosition+=scrollView.frame.size.width+4；
[self.view addSubview:scrollView]；
[滚动视图添加子视图：分隔视图]；
[滚动视图添加子视图：测试按钮]；
[builder addObject:testButton]；
}
[scrollView setContentSize:CGSizeMake（xPosition，scrollView.frame.size.height）]；
[self.view addSubview:scrollView]；

根据您的要求设置for循环条件部件。 希望这对你有帮助。
