问题 I'm trying to limit the number of touches recognised on a UIScrollView as it's executing with another gesture that has more than one touch required. I don't want the pan & swipe gestures to fire if the number of touches is greater than 1. But I'm having no success. I've subclassed the UIScrollView and overridden the obvious methods, but numberOfTouches always returns 1? -(BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer { if (gestureRecognizer.numberOfTouches > 1) {

问题 Ok. here is the story: I have a UIWebView in full screen, width = 768 It loads several images and those images are in one line, which means the UIWebView will scroll only horizontally. Now, I set the UIScrollView inside the UIWebView to pagingEnabled = YES. So the scroll on the UIWebView will move page by page. The problem is that every image's width is about 900. I won't scale them down and if I scroll the UIWebView, from the 2nd page on, always 132points of previous image will show. This is

问题 I have this code linked to a button on a ViewController with a UITableView as subview: -(IBAction)Action:(id)sender{ [tableView setContentSize:CGSizeMake(320, 1000)]; } This makes tha tableView scrollable to the bottom so that I can use a couple of buttons I programatically added to the bottom. So far so good. However, I want the tableView to be ok from the beginning, so I added the code inside viewDidLoad. Surprisingly, it doesn't work at all. Could somebody give me a hand? thanks! 回答1: If

问题 in my iPhone Application I have a UIImageView on the top and a UITextView below that. I want the UITextView to expand to the upper site and cover the UIImageView once the User starts scrolling.

There you can view the cover on the top and the upcoming title below, once the user starts to scroll, the upcoming titles view expands and covers the cover. How can that be done? Thanks. 回答1: Try to use one of the delegate methods of UIScrollView

问题 How can i detect which image object user is on? Trying to do it this way but it is not working - (void)scrollViewDidScroll:(UIScrollView *)sender { // [_imageScrollView contentOffset]; CGFloat imageViewWidth = _imageScrollView.frame.size.width; //int currentPage = floor((_imageScrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1; NSInteger image = (NSInteger)floor((self.imageScrollView.contentOffset.x * 2.0f + imageViewWidth) / (imageViewWidth * 2.0f)); [_imageScrollView contentOffset

问题 A little background: My app is designed as a web form in a UITableView. It is similar in format to the iPhone's Settings > Mail,Contacts,Calendars > "Account Name" > Account Info. A few differences: 1) I have a big text box on the bottom where you can put a "message body". 2) I have a big red button underneath the text box, similar to the red "Delete Account" button at Settings > Mail,Contacts,Calendars > "Account Name". the red button button submits the "form". The view described above fits

问题 I am trying to make a sketch pad app. I used UIScrollView for paging and UIImageView for the drawing. I put the UIImageView on top of the scrollView but it's not added to UIScrollView so it will not scroll. The issue now... It's not writing when...
