I Have a UITableView with sections and rows, one cell for sections and another one for rows.
Each Section got one UIButton that is just a normal + "image". First time I open the app I need to click this button twice for it to react, after that it reacts on the first tap every single time.
Does anyone have a good solution to this or is it an Emulator bug?

I have a tableview, 3 items in a cell, basically I am showing my items in grid view format with 3 columns and I am using tableview for this. This is fine. Now I want to achieve something like when I press any item on tableview/cell for long then all items will wobble and there will be small delete icon on their top left, when user press that icon then that item will be deleted, the way it happens in iPhone home screen.
Now first I want to know is how much feasible is this idea ? Like my only 2 rows will be visible at a time, and tableview reuses cell so if I scroll down and I delete any of the item then it won't create much hassle to manage delete of correct item right? And I want some direction of achieving that long press and wobble effect animation of items. What can I try?
For the wobbling effect animation code, check out this post.
And for the tableview management,you have to save the indexpath on the layer property of the view.
[imageView.layer addObject:indexpath forKey:#"indexPath"];
Now you are able to grab the cell and delete it.
I am creating an app in which user has been provided with the feature just like radio button.
I had added the button in tableview cell and its also acting like radio button but not in all cells working only in some of the cells.
Also the cells on which feature is working i have problem that it get deselected when i scroll the table view.
Please anyone help me out or provide a snippet.
Appreciate your help.
When the UITableViewCell scrolls off the screen, it is actually reused by the UITableView. You will need to account for this by saving off the state of each button in your model the moment they are pressed and then during tableView:cellForRowAtIndexPath:, read back in that value and set the button's state.
I need this kind of component to my iPhone Application. How could I Added to this to my project.
after i click that black color I need to animated it to left side and show next one.. like that
Try a tableView with one row and one section. Then the action of clicking on the row can trigger the delegate method of the tableView and use that to do whatever you like.
Alternately, you can make this a button with a custom view and swap out the view each time the user taps it.
I have a UIPickerView that pops up from the bottom of the IPhone's screen when a UITextField begins editing. When a row is selected my UIPickerView is dismissed.
But the problem is that don't manage to select the first row which is shown under the selection indicator.
Right now I can select all except the first row. So the UIPickerView never dismisses and I can't choose that value.
The only workaround I found is to scroll a bit the picker in order to still select the first row, so when I "release the touch" the first row is selected. But it's not a good workaround I need the same behavior I have with the other rows.
Thanks for your help as usual.

The way many apps do the trick is to add a button upon the picker to validate the selected item.
I'm building an app (not necessarily a twitter client) and I'm trying to figure out how developers create the buttons above and below a table view where a user presses them to either reload newer data or reload older data into a table view. Does anyone know of any tutorials out there that does this or know of an easy way?
If you want fixed buttons, you can just make your table view not use the full screen and add the buttons in the space. If you want the buttons to scroll with the table view, you can add a header or footer view to the table and put your buttons inside that.
Check the Three20 project. I believe there's a tableview there that does that.
It's actually not that hard to add inline buttons to a tableview. First you check and see if there's actually more data to show. If so, you want to add 1 to the number of rows returned from the datasource. When asked to draw that last row you return a cell that contains "Press for more" caption as well as a hidden spinner instead of the standard cell that shows your normal data.
If the user presses that last button the table view handler turns on the spinner then fires off a network event. Once the network request completes the data is processed and added to the same tableview datasource that was used to draw the first table.
Now all you have to do is tell the tableview to reload itself and the new data will show up. If you want to limit the amount of data shown you can prune out N number of items from the head of the datasource before redrawing so the memory-use stays manageable.
