How can i scroll my UINavigationBar according to a UITableView scroll,i mean:
When the user scrolls the UITableView down,the UINavigationBar should scroll with the UITableView and disappear;
When the user scrolls the UITableView up,the UINavigationBar should stay fixed on the top of the view.
I want a similar effect to this question but instead of a UISearchBar i need to do the same effect with a UINavigationBar,i've already tried the code from the link.Please any piece of code or source code will be appreciated.
Thanks in advance.
You can checkout the code for this library. It behaves a little differently (it mimicks the Chrome ios7 app), but you can easily rework the navbar handling to fit your needs.
I found an interesting post that might help.

I would do this by hiding the navigationBar of the ViewController and adding a fake UINavigationBar into the Header of the first section of the tableView.

I am trying to add a UILabel along with a UIWebView together in a view controller and want them to scroll together. So to accomplish that, i have added a UIScrollView behind these two views but the UIScrollView is just not scrolling. I am using Storyboard and iOS 7 SDK.
I have seen many questions but they are not of much help. Some are suggesting that i should disable the AutoLayout that i cannot do due to the requirements of my project. What else can i do to make it work? Thanks!
According to Apple's documentation, you shouldn't use UIWebView inside UIScrollView. What you can do is to add your UILabels and UIWebView inside aother UIView and then add this UIview inside the UIScrollView.
Secondly, you have to set the contentSize of the UIScrollView in order for it to work.
You also have to disable the scrolling of UIWebView that is embeded inside the UIScrollView.
Still if your problem is not solved. It is better to just turn of AutoLayout. I have had the same issue and i wasnt able to solve it without disable the AutoLayout.
The documentation for UIWebView states:
Important: You should not embed UIWebView or UITableView objects in
UIScrollView objects. If you do so, unexpected behavior can result
because touch events for the two objects can be mixed up and wrongly
handled.
You need to wrap the label and web view in a regular UIView. Add the regular view to the scroll view.
I have a UISearchBar linked with a UISearchDisplayController in the header of a UITableView in iOS7.
I set the UISearchBar with the style minimal. When the searchdisplaycontroller shows his table it has the behavior of the picture below. The table is scrolling above the searchbar. When I switch the style of the tableview to Prominent the table scrolls under the searchbar as expected.
Is this a bug or this behavior is expected?
The text isn't floating above the search bar, it's going below. Minimal style doesn't provide a background so this is expected. It will, however, provide a background during activation if there is a navigation bar present (Minimal style really wants to be over either no content or blurred content).
You are free to add your own custom background if you'd like.
Try with
self.edgesForExtendedLayout = UIRectEdgeNone;
in viewDidLoad method. It works for me.
I think this issue may for the Auto-Layout or Auto-Resizing. Just check in the nib file in insppector view.
Make the x=0 and y=0 for search bar and for tableview x=0 and y=44 , now you will get the tableview below the searchbar.
I have got a uitableview inside of a uiscrollview.
So the uitableview is smaller than the uiscrollview. And when I start to scroll down on the uitableview and it reaches the bottom, I am able to scroll in the uiscrollview.
And it works fairly. But not perfectly.
I would like to make the ux perfect so the scrollview would be kind of an extension (or another section of the uitableview). I don't want to add any section or footerview at the bottom of the tableview.
I was wondering on doing this by implementing something like this:
//
if tableview didscroll to bottom
then scrollview scrolltorect xxx
//
but it would only work if the uitableview was scrolling down.
I am not sure if this would replicate the correct ux behaviour.
Could you guys give me your advice on how to do this?
Thank you and best regards.
I found this very hard and difficult to execute so I changed my UI in order to put the bottom of the interface inside the tableview footer's view. This way the experience of scrolling my app got much smoother.
I've been searching for two days for a solution to this problem, and I just can't figure out a cohesive solution. What I'm trying to do is:
Have a UISearchBar with an extra button to the left like in this thread Adding button to left of UISearchBar.
Have a table view that shows the results that the UISearchBar is not part of, so that the search bar stays on screen even if you scroll down in the table view. I was only able to do this by separating the tableview and the search bar, meaning I can't use UITableViewController
Have refresh control on the table view. From this thread UIRefreshControl without UITableViewController it looks like I can't do this in a supported way if I can't use a tableViewController.
I've tried using the UIToolbar solution to adding a button to a UISearchBar, but the gradients don't really blend, so I'd prefer not to use that solution. I also haven't had any luck using any of the code snippets I've found here to add the button in a subclass in a way that can support autolayout for rotation.
Any help is much appreciated!
Perhaps you could make a custom object that just stacks a UISearchBar on top of a UINavigationBar and then use a UIBarButtonItem for the button that you are talking about. If you make this a re-usable custom object, you should be able to implement it app-wide.
I've got an UIScrollView with an UIImageView at the top and an UITableView.
inside every cell of the UITableView I've placed a UITextField
I would like to know how I can automatically scroll to the UITextField selected so that it doesn't go under the keyboard
I've already looked at this Get UITableView to scroll to the selected UITextField and Avoid Being Hidden by Keyboard but it doesn't works very well for my situation..
could you help me?
Thank You!
Check out Matt Gallagher's fantastic Sliding UITextFields around to avoid the keyboard. It ought to be just what you need. You can modify it to only scroll a specific element, or just leave it as is to scroll the whole superview.
