uiscrollview

问题 I have a scrollView with paging enables. I have a UIView as a subview of the scrollView. When the scrollView reaches the buttom of it's content, I'm turning scrolling off: scrollView.scrollEnabled = false because I'm doing other things that require dragging in a part of the scrollView (Yellow part). So the scrollViews offset locks at the buttom of the page. I want to be able to drag in the UIView (red), to enable scrolling of the scrollView, and thereby change the scrollviews content offset.

问题 Cell doesn't receive touch events, when there is UIScrollView inside UITableViewCell. Is there any way to cancel tap events for UIScrollView (needs only to handle scrolling)? 回答1: If you need touches to go through, implement a subclass of UIScrollView, and add these: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { // Pass to parent [super touchesBegan:touches withEvent:event]; [self.nextResponder touchesBegan:touches withEvent:event]; } - (void)touchesEnded:(NSSet *)touches

问题 I'm using the PageViewController (https://www.cocoacontrols.com/controls/pageviewcontroller) to create a Magazine App similar to Wired. I've used this code on CustomPagerViewController to load the childview's: - (IBAction)btn_index:(id)sender { NSInteger currentPage = 3; CGPoint offset = CGPointMake(currentPage * self.scrollView.frame.size.width, 0); [self.scrollView setContentOffset:offset animated:YES];} But I need several buttons on the indexviewcontroller to load the correct views and

问题 I have an application in which i am calling image from URL in image view. Image view is add as subview of scroll view. In my implementation file i have use this code - (void)loadView { [super loadView]; // add gesture recognizers to the image view UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)]; UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)];

问题 I added a ScrollView to my View Controller. Then, I created constraints between my inner elements and the scroll view itself, but I don't understand why my yellow view for example is not taking the full width. Here is the screenshot of my view and constraints: And sometimes I get this, why? When I don't use Scroll View, all works perfectly. 回答1: Control drag from the mapView to the outer main View and select Equal-Widths 来源： https://stackoverflow.com/questions/48708331/views-in-scrollview

问题 I am creating a paging UIScrollView following this tutorial. This is the Swift code which allow paging of images with UIScrollView . However, it has a limitation. I am unable to zoom the images. class PagedScrollViewController: UIViewController, UIScrollViewDelegate { @IBOutlet var scrollView: UIScrollView! @IBOutlet var pageControl: UIPageControl! var pageImages: [UIImage] = [] var pageViews: [UIImageView?] = [] override func viewDidLoad() { super.viewDidLoad() // 1 pageImages = [UIImage

问题 I have a uiview with a uiscrollview as a subview in a nib. Then, I load another uiview with a uitableview as a subview of this other uiview (among other elements inside this view) as a subview of the uiscrollview. That is, UISCrollView -> UIView -> UITableView (and some other views inside the UIView). And I need to do the following: Once I know the final height of the tableview (depending on the number of cells and height of them) I need to resize the uiview containing it and, in turn, resize

问题 I want to display the image(which comes from webservice) the format such that the output in the screen appears like below image:- Now the logic i had implemented is,i had added the image in uiscrollview. with the below logic:- for (int j=0;j<9;j++) { for (int i=0; i<[mainRestaurantArray count];i++) { if ([[[mainRestaurantArray objectAtIndex:i] valueForKey:@"Image"] isKindOfClass:[UIImage class]]) { [CombineArray addObject:[mainRestaurantArray objectAtIndex:i]]; //NSLog(@"cnt=>%d array==>%@"

问题 I am using autolayout in Xcode and am creating a fairly tall (1300px) ViewController with a uiscrollview to navigate up and down. I made the viewcontroller freeform so its dimensions are [375,1300]. I then incorporated the scrollview, added the content view as well as all the subviews & constrained everything, leaving no constraint errors. At runtime there are no errors, but everything is all smushed into the normal screen size when I intended for it to be very tall (~1300px) and scrollable.
