How to disable vertical scrolling in UIScrollView

Question

I want to disable vertical scrolling from my UIScrollView if possible.. My code is like below.. Working fine except users can scroll up and down which shouldn't be there I believe.. Thanks in advance..

    UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 100, self.view.frame.size.width, self.view.frame.size.height / 3)];   
    scroll.contentSize = CGSizeMake(scroll.contentSize.width,scroll.frame.size.height); 
    scroll.pagingEnabled = YES;
    scroll.backgroundColor = [UIColor blackColor];
    int xVal = 30;

    NSInteger numberOfViews = 5;
    for (int i = 0; i < numberOfViews; i++) {
        UILabel *testLabel1 = [[UILabel alloc] initWithFrame:CGRectMake(xVal, 0, 90, 100)];
        UILabel *testLabel2 = [[UILabel alloc] initWithFrame:CGRectMake(xVal, 20, 90, 100)];
        UILabel *testLabel3 = [[UILabel alloc] initWithFrame:CGRectMake(xVal, 40, 90, 100)];

        testLabel2.backgroundColor = [UIColor clearColor];
        testLabel2.text =@"Test1";
        testLabel2.textColor = [UIColor whiteColor];
        testLabel2.font = [UIFont boldSystemFontOfSize:12];

        testLabel1.backgroundColor = [UIColor clearColor];
        testLabel1.text =@"Test2";
        testLabel1.textColor = [UIColor whiteColor];
        testLabel1.font = [UIFont boldSystemFontOfSize:12];

        testLabel3.backgroundColor = [UIColor clearColor];
        testLabel3.text =@"Test3";
        testLabel3.textColor = [UIColor whiteColor];
        testLabel3.font = [UIFont boldSystemFontOfSize:12];

        xVal += 120;

        UIView *view = [[UIView alloc] initWithFrame:CGRectMake(xVal, 30, 150, 130)];
        view.backgroundColor = [UIColor blackColor];

        xVal += 200;

        [scroll addSubview:testLabel1];
        [scroll addSubview:testLabel2];
        [scroll addSubview:testLabel3];
        [scroll addSubview:view];
    }

    [self.view addSubview:scroll];

disabling vertical scrolling in UIScrollView

or you can also try this:

self.scrollview.contentSize = CGSizeMake(self.scrollview.frame.size.width * number_of_items, 1);

Answer 2

you must set your scrollview content height to the scroll view height

CGSize scrollableSize = CGSizeMake(scrollableWidth, yourScrollViewHeight);
[myScrollView setContentSize:scrollableSize];

Answer 3

You should do like this:

aScrollView.scrollsToTop = NO;
aScrollView.delegate = self;
aScrollView.contentSize = CGSizeMake(aScrollView.frame.size.width * X, aScrollView.frame.size.height/2);

Answer 4

In your xml file there are two properties are available for scrollview are horizontal scroll and vertical scroll. as per your requirement you can check or uncheck and if you want to stop vertical or horizontal scroll then you have to make same content size of scrollview with height or width of scrollview respectively

Answer 5

There is no problem with that simply change the contentSize of your UIScrollView and you are done.Increase its width size and its height should be as it is at present.Moreover you can also hide the vertical scrollers also.

scroll.showsVerticalScrollIndicator = NO;
scroll.contentSize = CGSizeMake(scroll.contentSize.width + xVal,scroll.frame.size.height); 

Answer 6

Assuming it's an iPhone app, so the screen resolution is 320×480 .

Now you are setting your scroll view's height as self.view.frame.size.height / 3 . Here your view's height is actually taken as 460 and not 480 (20px for staus bar).

So when you add the other view as subview to your scroll view, its frame goes out of the scroll's content view. So you need to manage this while setting your frames/content size.

Let me know if this works for you.
