@KumarKl No `IBOutlet` used only Drag and Drop `UITextField` using Interface builder and Run the Project only in one and another new project working fine. :) — Buntylm, Mar 26 '14 at 11:33
@AhmedZ. No Code I added `UITextField` using Interface Builder — Buntylm, Mar 26 '14 at 11:34
how about the superView of it .. if all fine, then it might be a bug. — Kumar KL, Mar 26 '14 at 11:48
It's unlikely to be an IOS bug but may be a "feechure". You need to reproduce the behavior in a minimal app and post the code here. — Hot Licks, Mar 26 '14 at 11:54
Guys i Also Added `Youtube` Video Link as what issue i am facing. [please review](https://www.youtube.com/watch?v=Rm1LwZe68ks) — Buntylm, Mar 26 '14 at 12:33
whats the behaviour if you set the font back to the default value? Is the font you used a provided font in iOS or a custom one you added? I have seen a lot of problems with fonts that were originally intended for print use having there baselines way off when used in an app. — Cocoadelica, Mar 26 '14 at 13:04
I Deleted the last one `UITextField` and created new as this one is fresh one as given by `UIKit` — Buntylm, Mar 27 '14 at 04:12
Should I submit this issue to `Apple` with my `iOS project` ? — Buntylm, Mar 27 '14 at 05:54

I had the exact same issue. Didn't have this in a previous release of my app 2 weeks ago.

I've found that the issue is coming from presenting a view controller embedded in a navigation controller with a translucent navigation bar.

I set opaque bar in the simulated metrics of the navigation controller I was presenting and no more issue with UITextField.

On my case at least, everything were resolved at the moment I set opaque bar for top bar in simulated metrics in InterfaceBuilder for my UINavigationController which embed a UIViewController I've wanted to present modally

Hope it will be the same for you as well.

Same problem just arrived here, and I reached this post via Google. In my case, the UITextField was added in a xib, in a view controller presented modally, and I needed the navigationbar to remain translucent.

So the only workaround I found was to remove the outlet from XIB, and add it programmatically in viewDidLoad method.

That did the trick.

In my case it was when UITextField was added as first element of UI. I worked with StoryBoard, so I put another element (UIButton) to first position and problem disappeared.

Maybe the solution is this: func textFieldDidEndEditing(textField: UITextField) { textField.layoutIfNeeded() }

taken from here:

Text in UITextField moves up after editing (center while editing)
