Are there any alternative controls instead of UIPickerView in XCode. If yes, how do they work? Can anyone suggest an alternative for UIPickerView?
You can see one in action if you download the free One Stop Plus app (women's clothes), drill down on the products until you get a view with Color, Size, etc. Tapping those buttons animates a table out of the button, with choices. Selecting one causes the table to animate back into the button. If you like that post a comment to this answer and I can tell you how to do it.
With iPhone interface, it is not feasible to enable a Combo box like a website. (I believe even Apple Guidelines would say not to do it). What you need to do is the use the UITableView to enable users to pick one option.
One thing you can do is decide whether you want to have the choice in a view shared with other controls. OR if your list if too long you can chose to push in a new view with only the choices on them and when a user selects one, the view will pop back one level.
Here is a screen shot of what i mean (maybe not the best example out there):

Right now i am developing app. One of it's ViewControllers has tableview with list of blog posts. I want to put some control so user can select blog's categories and then app will show posts only from those selected categories.
I thought it would be nice if there will be "filter" button in top right corner of my app's viewcontroller. After pressing it dropdown list of category appears and user can select categories.
What custom UI element can handle it?
Really there's a ton of options at your disposal, not including all the custom elements you can probably grab from GitHub
For an iPad, you can use a UIPopoverController https://developer.apple.com/library/prerelease/ios/documentation/UIKit/Reference/UIPopoverController_class/index.html
Depending on the number of filters and the style of the design, a good starting point could even be a UIActionSheet.
If you want to do something really fancy, you could have a second UITableView hidden underneath by your main UITableView containing the blog posts, and then when the "Filter" button gets hit you can animate your blog UITableView slightly over revealing your filters menu (maybe even shaded slightly darker to give a feeling of depth to the app)
I searched for a while and can recommend CZPicker https://github.com/chenzeyu/CZPicker because it very nice and easy picker view for iOS that supports iOS 7 and is well working not only iPhones but whit iPads too.
It's the first time I'm creating a keyboard for iOS. I've created the first page with all the buttons but I don't understand how to add the second page.
For example: first page QWERTY, second page 123.
Is here anyone that can explain all the passages and functions/classes that I have to add on my codes and where precisely?
Thanks a lot
Well I haven't built a custom keyboard personally but I would make seperate views for the "pages" of keyboards and just hide away and unhide the view of the keyboard you want to show when the user presses the "alt" button. You could have as many keyboards as you like with this method and have it pre-built in the backround so that it would function very quickly to swap between them. Or animate them as you like really as views are easy to slide around. Actually sounds like a lot of fun as I have often thought about building a keyboard that has alpha-numeric values all in one, which would make filling in details on a login screen much quicker/more convenient.
In one of my views I need a control that lets the user multi-pick items on a horizontal, graphical list (tap to select, tap again to deselect...think: locking pushbuttons across the screen).
Rather than laying out a bunch of UISwitch controls side-by-side I want to use something prettier...icons of the elements being chosen. I thought a custom UITabBar might do the trick.
Is there a way to get the buttons on a UITabBar to lock state in a multi-pick fashion? So if my user taps the 1st, 2nd, and 4th buttons they stay selected but the 3rd, 5th, and 6th don't?
(If not, I guess I can build something. Can a standard UISwitch control take on a different look?)
Thanks!
Nope, there’s nothing in the UITabBar API that indicates that you can have multiple selections.
As for customizing UISwitch—that’s not what you want. As of iOS 7 you can no longer set a custom “on” or “off” image. You’re better off customizing UIButton, which isn’t quite as close semantically, but which still provides all of the API you’ll need for your application.
I am writing a small iPad app using Storyboards. On the first screen the user will be presented with about 7 pieces of information to enter.
Several pieces of information are of the form "How important is X to you" with 5 or 6 possible answers, like "Extremely Important" and "Very Important" and so on.
I think the correct design pattern is to have a Button on the storyboard with the value on the button, and the user can change the value by tapping the button, and then I will present a list of values in a UIPopover in a ContainerView.
First, is this the best design pattern.
Second, can someone point me in the right direction for accomplishing this? I just can't seem to get the pieces to work.
I am thinking that maybe I do not need the Container View, just the UIPopover.
Any help would be greatly appreciated!

I suggest using a UITableViewController in a popover. The table contains all the valid options in the appropriate order. When the user taps (selects) a row in the table, invoke a delegate method that passes the selected option, sets the button text, and dismisses the popover.
I am building an iOS app that allows the user to browse a tableView, click a cell, then navigate deeper into another tableView using a navigationController.
I have a requirement to be able to move any of those items/cells to another place in the navigation stack. Right now my idea is, once the user selects the cells to move, to display a modal tableView that will allow the user to navigate through the same structure as before, but this time choose the location (by pressing and holding) to place those cells.
Are there any other UI ideas or clever programatic ideas that anyone might have that could be a better solution to this problem?
Perhaps take a look at how Apple's iOS Mail moves email messages between different mailboxes?
This also basically displays a modal view controller, but it flattens the hierarchy, by indenting nested items below their parent objects. You than just select the item that is the destination.
This of course only works if your hierarchy is not too deep, otherwise it's probably best to do it like you outlined it. The only thing I would perhaps recommend doing in addition, is to also have some sort of visual method (button?) to select the destination. A long press by itself might not be intuitive enough.
