I have a view with a UIScrollView, UIImageView for a background, and a UITextView. I have created several other views just like this and they all come out okay - with a background image and scrollable text but for some reason, now I can't make that work. Either my image overlaps all of the text so that I can't read it or the UITextView default background (white) shows up so that the user can't see the background image. What could be causing this problem?
Do you use Interface Builder or build the views hierarchy in code?
In both cases you should make sure that the order of your views is correct.
In IB the view that you want to appear on top of all the rest has to be under the rest of the views.
In code, make sure that the text view is the last to be added to the hierarchy.
You could also use the next code in order to check if this is the problem:
[self.view bringSubviewToFront:textView];
Okay, it must have had something to do with choosing the delegate. I can't say that I completely understand how I fixed it but it had to do with declaring the delegate in IB.

I have an application with several (8) different Views in a UIScrollView. They are circling so that you get to the first when you try to get "behind" the last and vice versa.
My problem is how to create a titlebar like in the Stream of the Google+ App. There the titles are circling with the pages and show the current visible page.
How could I realize that? Would it be possible to create a general class to use such a view in many different apps?
I've already tried to solve this problem with some different approaches, but they all didn't work (well). I can display labels above my scrollView and move them, but how far and with which text seems to be difficult for me.
So now I'm looking forward to your answers ;D
Try using two UIScrollView, one for the content and one for the headers. The header UIScrollView would be controlled by your view controller that is also a delegate of the main UIScrollView. Update the header UIScrollView whenever you receive a -scrollViewDidScroll: message from the main UIScrollView.
I think you need to add label in customview and then add customviews in scrollView, you will get events for individual view, so you can rotate that view according to angle and keep label at fix place...
I wanted to know how can we design the view controller such that.., the upper half of the screen remains fixed and the below part of the screen can be navigated through.. !!
Should we use slipScreenController here ?
Your description sounds nothing like the Appstore app but the Appstore app simply has one vertical UIScrollView and another horizontal UIScrollView inside that for images.
If you are referring to browsing categories in AppStore then:
That is a tableView implemented in such way that it doesn't take the whole screen area. You need to create a UIViewController (not UITableViewController) and than add a tableView to the view (using Interface Builder or code). That way you can change the size and position of the tableView and use the remaining area of the view for something else, for example a UISegmentedControl above the tableView.
If you are reffering to reading description and images of single app then I think that UIScrollView is used for displaying images, not sure about the rest.
I want to make a small area to present some information in the middle of a UIToolbar and was wondering what the best way to do this is.
I need to show some text and a graphic, both of which need to be updated (around every 3 seconds) as new information arrives. The graphic is similar to the iPhone signal strength indicator, so it can be either custom drawn or selected from one of 3 graphics (low, medium, high strength).
I'll probably use initWithCustomView: to create a UIBarButtonItem, although I would like the view to be clickable (to allow the user to change the information shown).
What's the best way to make that view? Can I use a NIB, or do I need to do custom drawing in the view? What's the best way to update the buttons? I'm assuming that I'll have to remake the toolbarItems array each time and set it when the information changes. Is there a cleaner way to do this? Thanks.
Using initWithCustomView: sounds like a good way to go. You can create your custom view any way you want: with a NIB, by drawing it, even using images. It can also have its own subviews. It can be any object that inherits from UIView. (So, if you wanted, you could even make it actionable by using a UIButton, a custom UIControl, or a custom UIView with a gesture recognizer attached.)
You shouldn't have to remake toolbarItems (or, for that matter, do anything with it after you've added all your button items) if you just keep a pointer to your custom view UIBarButtonItem. It could be an instance variable. Then, to update the custom view, you could access it as you would any other view. I've never actually tried this, but I can't see any problem with doing it.
You sound like you had it mostly figured out. Hope this is helpful.
I needed the same solution and was hoping for some code examples from you. So I ended up doing it all in IB and the steps are here as follows:
Create UItoolbar in IB with no Items. (A Bar Button Item will be added again once you add the UIView)
Add UIView as subview of UIToolbar
Add UILabels to subview of UIView that is already a subview of the UIToolbar.
Create IBOutlets from UIToolbar, UIView and each UILabel and then you can reference the labels in your app.
I did set the backgrounds to clearColor so the text appears on top of UIToolbar without any box or borders.
And the text updates dynamically which was the desired outcome.
Hope this helps someone as this has been eluding me for a while.
My app has a ManagedObject that has different types of fields
So, I want it for the user to edit each one and also have it display different info for each.
If you look at the Calendar app, when you Add an Event, you'll notice Title/Location in one cell, Starts/Ends in another, Repeat... so on.
So... in Interface Builder I have all my UITableViewCells but they are all squared. Not with neatly rounded corners.
Is this done with IB and I'm missing a setting? Are they all different views amassed in one place?
I know I will have to custom code each one. I just want the rounded corners first.
To get rounded UITableViewCells, change the style of your UITableView from "Plain" to "Grouped". This can be done in Interface Builder. Then, since it's actually the edges of each section that get rounded, put each cell in its own section.
For me the problem was that I made a subview of UITableViewCell and put all my controls in there. If you do that, then you'll see the corners cut. After dragging everything on the content view, the problem was solved.
I have an iPhone application that uses a UIScrollView to display a larger version of an image on the main screen. I am using IB to create the main screen that has text, small images, and price about a product. I have it setup to show/hide the UIScrollView if the user touches the small images. It works ok, but things are pretty messing in the IB layout. I have to put the UIScrollView over top of everything else and make it hidden by default. What I'd like to know is if there is a better way to accomplish this. Can I create a new nib and load the scroll view in it and load that nib when the users touches the small image? Should I construct the scroll view in my code and not use IB? Any input is appreciated!
Sorry if this is a newb question. I'm still learning.
Set scrollView.hidden = YES and then when tapped, set it to NO.
