I'm quite new to the Xcode programming. I've added some view controller, labels, buttons and image view to my program, but, when I try to adjust, for example, the size of a label, the view controller that that label is in, gets displaced. I mean, when I try to drag the side of the label to change its size, the view controller moves down, making my label get displaced in the view controller. It is a very weird situation, here you have the screenshot of my project, the view controller misplaced is the one that says "Perfil" on the navigation bar. Every time I try to change one of those light blue views size, the entire view controller changes place. The more I try to change the side the more it will go down.
Sorry for my English, not my native language.
I think the bigger issue is that you are using Table View Cells that are not part of a table view.
Table ViewCells are supposed to be a part of a UITableView and not just stuck in a view.
Using UITableViewCells in this way is what is causing the strange behavior.
If you are trying to make a table, put a UITableView in your view, and then you can customize the table view cells in there.
It you aren't trying to make a table, just use UIView's instead of those UITableViewCells.
I have two ideas that may fix the problem:
First, if you're trying to drag and drop the label but the view controller moves instead, then you might just be grabbing the view controller's background by mistake. When this happened to me, it was because the order of my components in the xib file was wrong. Things are ordered from back to front, and when you click and drag something, you'll just be clicking and dragging whatever's on top. You can try and get past this by clicking the UI element on the left to be sure you select it, then dragging the handles.
It looks like you have things in a reasonable order, so that may not be the culprit at all.
Second, if that doesn't work, select the element you want to edit on the left, then open up the utilities pane on the right. Click the Attributes icon (should be fourth from the left) and look towards the bottom. You should see something like this:
Just manually edit the position and size of your labels there. You should see the change immediately reflected in the display.
Hope this helps!
Setting no autoresize behavior in Interface Builder solves the issue.

I'm working on a screen that has a UITableView below the screen(thus invisible) initially, but will pop up when user click on a button. I know it's not supposed to be seen on the screen, but just for the sake of design, is there a way to make it visible when I'm working on main.storyboard?
Please see the picture attached below. It's really hard to work on the UITableView when it's beneath the toolbar. How can I force xcode to display them so it's much easier to work on?
You can't, but you have 3 workarounds:
Move it into view (Xcode will complain that it's not in the right position, but it doesn't matter)
On the bottom left on your storyboard, you can open up the view hierarchy, you can find your element there for creating constraints, linking it with your code and everything else you'd want to do.
Increase the visible size of the viewcontroller on your storyboard, trough selecting your viewcontroller on the storyboard, changing Simulated Size to freeform and increasing the values (will not affect size when running).
The easiest way to deal with this is to:
open storyboard
select the viewcontroller you want to edit
open the Size Inspector
Switch from Fixed to Freeform
Type in a larger height (like 1000)
Simplest thing is to manually do what your button does in the app.
In the view hierarchy on the left, select your table view and move it down to the bottom. This will bring it to the front in interface builder.
When you are done, move it back.
I do this all the time and you get used to doing it. Just watch out for accidentally moving it inside another view when you drag it down or up.
I have a UICollectionViewController setup. It shows something kind of like a gantt chart, with selectable bars, scrolling, etc. I want to have a "trash/delete" button that always floats in the bottom right of the screen, regardless of scroll. It will delete the current selection (if there's one) in the UICollectionView.
I see two basic approaches:
Use the Supplementary Views facility of my UICollectionView. What I dread about this, is that I'll have to muck with its layout in my layout (I'm using my own subclass of UICollectionViewLayout) to keep it positioned in the bottom right corner, regardless of scroll.
Just add a UIButton to the canvas and set it up there. Maybe this isn't even a real approach, because this is what I wanted to do. While my button may manipulate items found in the UICollectionView, it's not really a real member of the collection view. But I found when I tried to drag a UIButton onto my Controller in the storyboard, it wouldn't stick. It doesn't seem to want to add it. Do I have to change to use a UISingleViewController, and then have a top level view that I can add both my button and collection view into? And then repeat all of the handy delegate/property setup that I get for free from UICollectionViewController?
You:
drag a button on to the view
in storyboard/xib.
Then, in the hierarchy column on the left, ensure it is at the bottom. That means it will be in front of everything else.
So, if necessary move it so it is in front of (ie, below in hierarchy) the collection view.
Note that there is absolutely no problem, at all, with putting one control "in front of" the other (i.e., so that it "blocks" you from seeing all or part of the other one).
If you had a problem doing this, you've made a trivial mistake. For example you may have dragged the new button "into" the collection view, rather than as a "sibling of" the collection view. Hope it helps.
This might be a simple question but using storyboard I can't seem to position my table, a message field and a button correctly. In the picture below, if it's positioned that way, only then do I get to see the text field and button at the bottom of the screen and the table view takes up the rest of the screen. If I drag the text field and button to the bottom and resize the table, the text field and button disappear and the table is cut off. Why is that? Is there a solution to this without doing it programmatically?
Easy solution is to remove all constraints then position them where you want them.
You'll find you get different effect when try to reposition items depending where you drag from for example double tap an item and nudge it with arrow keys or grab the middle to move it resizing via the corners.
But in my opinion it's easier remove all constraints from the view and then set them as you go.
Also you might want to consider using a container view for the table view and have a separate UItableViewController that way you can easily separate out that the tableview logic from the other ViewController. It will help stop things getting a little messy later on as project grows.
I've been searching through here and googling like crazy for a possible solution to this problem. Thus far I'm turning up exactly nothing that actually fixes it so I'm hoping someone can help.
I'm working on the UI for a iPad app. I'm doing it using interface builder. I worked with storyboards briefly but I don't like them all that much so I'm sticking with IB for now. Unfortunately I'm not very experienced with the workings of IOS Ui but it's been going relatively smoothly so far. In my app, I have a view controller, which holds a view containing a pair of sub views. One subview contains a rather windows like header bar (i like the look). The second contains a UITableView. The UITableView is set up properly as far as I can tell, and feeds it's info from a data source using custom UITableViewCells. The UITableView is set to grouped though currently there is only one section. The table is in edit mode by default because I want the user to be able to add new items and use the VC as a selection dialog. The view controller is presented (rather than pushed) using UIModalPresentationFormSheet (again, because I like the view) but I don't know that has any bearing on the problem. The cell border is flush with the X origin, the only reason the text isn't currently starting there is because I went into my cell and move the label over, leaving a gap between the edge of the cell and the label containing my text.
The Offending View http://bit.ly/144cbjT
The Problem: The UITableViewCells, for some reason are positioning themselves at X: 0. This puts them outside the border drawn on the UITablewView when you set it to grouped style. I could probably just turn off the border and get away with it, but I like the look so i want to keep it. I've tried messing around with constraints and anchor points on the cells, the content of the cells, the table itself, the view... I've tried simply moving my cell's labels over a bit. I've also had clipping subviews turned on and off. I've made sure the controls are being loaded properly from the XIB. I've made sure everything is added as a subview where needed. I've made sure I've tried everything I could think of short of setting the cell's X position in code. But since I'm not sure how to tell where the border is, I'd rather have the tableview or the cell do the work itself.
The question: How do I fix this? The selection accessory should be outside the grouping box. The text should be inside, not bleeding out onto the background like it is.I believe the content of the cell should be displayed inside the border within the yellow area.
The odd thing is, this is my fifth or sixth table in this app and I've been doing them all basically the same. Thus far this is the only one I've had trouble with.
Can anyone shed some light as to what's going on?
Thanks in advance
I think that to get this in code, you'd have to do something explicit, so the most likely candidate is a messed up IB file.
Since it doesn't cost anything, I'd just delete the tableView from the IB and then re-add it. If that doesn't work, try recreating the complete IB.
Hope that helps
I have unfortunately decided to make my app using the IB, which I discovered was a terrible choice, but I'm afraid I must deal with it.
So originally, I had all my fields, buttons, etc, placed on a single view, with enough space left on the bottom that on the 3.5" screens everything displays neatly.
Well was that a terrible idea. Now I need to add just a few more things to the screen, and although it works in the 4" mode, 3.5" is out of luck. "Ah ha," I thought, "All I need to do is add a scrollview containing everything on my screen, and for the 3.5", it will scroll instead of reposition.
Long story short, I added my subview, placed it as the very back object on my screen, draged all items into it... And I got a mess.
Ain't that just dandy.
Anyways, I would like to know if there is someway to get Xcode to not reposition all these elements when I do this, or, is there another way to get all these elements to become subviews under this scrollview.
First select all the views from the tree on the left. Then click once on the view controller's frame (the black status bar, not the objects inside the controller). Now press cntl-c to copy all of them. Now double click on the view you wish to add them to and paste them. This will retain all the view's layout locations. If they don't copy over exactly into position just hold down shift and press the arrow keys to get them into position. Dragging the views into another view reset all the position back to the center.
