Helge: Attaching a UIToolbar to the iPhone's Keyboard

nospam@example.com (Helge) — Sun, 11 Apr 2010 14:10:38 +0200

I just solved this simply by observing notifications I needed to track anyway. In my case these were delegate messages coming in from a searchbar:

- (BOOL)searchBarShouldBeginEditing:(UISearchBar )searchBar
- (BOOL)searchBarShouldEndEditing:(UISearchBar )searchBar

I just simply added my own animation for the searchbar to move in. I figured out which kind of animation the keyboard used just by guessing & try+error. ;-)

Works fine! But this is definitely the better approach. Problems I have now deal with change of orientation of the device...

happy sunday,
Helge

dj,

I haven't checked that situation yet, but I should be able to give it some attention shortly.

I'll get back to you when I have a solution.

Cheers,

dj: Paging-enabled UIScrollView With Previews

nospam@example.com (dj) — Thu, 01 Apr 2010 08:40:27 +0200

the scrollView itself is not responding to any touches. for example, i added a button on the scrollview and it doesn't receive any touches. I think the ARScrollView is blocking it??

Is there any way to solve this problem?

Anya,

sorry for not getting back to your earlier. You will have to leave some empty space at the sides of your views so that they don't seem to stick to each other.

Hope that helps.

Cheers,
Alex

Thanks for this great reference, there is a little documentation about paging in scrollview.
I have one issue though, which you might have a clue about:
I have used the same parameters you have used, but when adding a view different from uiimageview used in the example , I see the scroll view connected without the spaces between the views as you see in the images example.
Any clue ?
Thanks a lot.

Good point, this might be necessary if you have a more complex view layout.

However, for this simple example, the shorter version should suffice. :)

Or you can just call super with more flexibility when dealing complex subviews:

- (UIView )hitTest:(CGPoint)point withEvent:(UIEvent )event {
UIView *child = [super hitTest:point withEvent:event];

if (child == self) {
return self.scrollView;
}

return child;
}

Thanks for this pointer, I did something similar for a project but it involved making an 'infinite' horizontal scroller for tableviews, but the app didn't have any kind of 'preview'. I just kept 3 views around and kept reusing them / redrawing the content depending on which "direction" the user went. But this is great, thanks!

Alexander Repty: Attaching a UIToolbar to the iPhone's Keyboard

nospam@example.com (Alexander Repty) — Sun, 24 Jan 2010 22:05:07 +0100

Eric,

I'm glad you enjoyed the tutorial.

I've faced the same problem you're currently facing before, and I solved it by adding an instance variable to keep track of whether the keyboard is already displayed (or is currently being animated) or not.

You might want to consider having different states (animating in/is currently being shown/animated out) and set those in -keyboardWillShow: / -keyboardWillHide: and another method you set up via + (void)setAnimationDidStopSelector:(SEL)selector.

Then, you can act accordingly in -keyboardWillShow / -keyboardWillHide and only run the animation when it's appropriate.

Hope that helps,
Alex

This is a great tutorial. Thanks!

The trouble I have with this method is that if I have multiple text fields in a form, then the animation of the toolbar happens as my user clicks from one text field to the next. Even though the keyboard changes from, say the default alpha to the number pad as the user moves from field to field, it does not actually animate on and off the screen. Yet my controller still gets the willShow and willHide notices and kicks off its own animation.

Does anyone have an idea how to determine whether the keyboard is really coming or going?

Tim,

I haven't seen that issue before, but I'll be sure to check it out and if possible work on a fix for the next version.

Cheers,

The latest version of LabTick seems to have an issue. I typically have my brightness set to the lowest setting, but each time I log in it's set to the highest setting and I have to change it. It's like it's confusing 100% off with 100% on.

Alexander Repty: Asynchronous Networking Using NSOperation And Delegates

nospam@example.com (Alexander Repty) — Wed, 07 Oct 2009 17:00:17 +0200

Ed,

in this simple case, NSURLConnection and its delegates would probably suffice. However, I wanted to illustrate the point of using NSOperation and NSOperationQueue.

If you have a huge library designed for complex operations, I think of the NSOperation-based approach as cleaner. All the logic for this particular step and associated tasks ends up in a single operation, which is executed asynchronously in its entirety and will only give control back to the delegate once the results are there.

Maybe this is just a question of flavour, but I'm all for strictly seperating these tasks. That doesn't mean that your approach would be worse though. :)

Cheers,
Alex
