Show less records initially in UITableView in iOS SDK - iphone

When I hit the server i am getting multiple records, but I want to display only three records for each section in UITableView initially.
Later on user press more button I want to display more records.
Can any one please give any ideas on these.
Thanks in advance.

control your numberOfRowsInSection.
Return 3 initially when user presses more update the row count to your data(possibly an array) count and reload the section.

You can see this sample . If you just want to display few records at launch time n later on want to load more cells, this might help you ..

Using addHeaderView in Android

On clicking the button following happens to the ListView:
1. Through addHeaderView the header is displayed.
2. SimpleCursorAdapter displays data from the database table.
Now when I click the button again then the header duplicates, in the list while the data from the table is correctly displayed.This keeps happening every time the button is clicked.How to solve the problem.
The Adapter does not provide HeaderView-s and doesn't count them.
Use ListView.getHeaderViewsCount() to get the number of header views. This is how you can avoid adding unnecessary views.

customized uitableview with chat bubbles

I'm building a SMS like app, with chat bubbles. To do that I'm using a customized uitableview which gets data from an array and puts cells with pair indexPath on the right and with odd indexPath on the left
Everything works fine, but the only problem is that there can't be 2 cells one above the other in the same same position (left or right) and I need this as maybe a user can send 2 or more messages while the other one didn't send anything
I'm thinking in a way of doing that but nothing comes up to my mind so do you suggest a way ?
You can't assume that the two users will alternate messages back and forth, so the even/odd check will have to be thrown out.
You mention you store the messages in an array. Perhaps create another array of the same size, and when you add a message to the first array, you can add something to the second array that lets you know which user it is from. Then, when you create your cells, you can determine if it should be on the left or right using the second array, and fill the content of the bubble from the message array.
Could you just check if the message originated from the device I'm holding and put it on the left side?
If the data you are pulling from somehow identifies the user, you could easily check which user sent the message and position the cell based on that.

how to display just 10 rows in uitablView iphone application

I have a large data to be displayed in Tableview cell can anybody tell me how to show just 10 of them after click display button.
and then add more 10 when user click on load more button.
Thanks in advance.
In the "number of rows i in section method" return a integer wich initially is 10. When the "load more" button is clicked add 10 to the integer and reload tableview.
You need to go give this a try first. People here will be very willing to help, but this isn't a "code it for me for free" site.
Here's the idea: Load your 10 out of however many items into an array or NSDictionary or what have you. Initialize your table with the same number of rows as you have in that data object (in -tableView:numberOfRowsInSection:).
Then build a view in the .tableFooterView property that maybe reports on how many of the elements are being displayed out of how many, and has a button to load more. Attach a target to that button to call a function that loads the next 10, and calls -reloadData on your UITableView.

Prompting user for multiple selections in an iphone app

I'm currently looking for a way to provide the user with being able to select multiple items from a collection of values.
I know this is done in the mail app whereby you can go into the edit mode of a folder and select multiple items by clicking on the circle on the left hand side.
What I'm unsure about is how this is achievable. Is anyone familiar with how to reproduce such functionality?
Thanks,
Matt Delves
The easiest way is this:
Provide a UITableView with all values the user can select.
Keep a mutable array with one object (e.g. an NSNumber) per table row to store each row's selection state.
In tableView:didSelectRowAtIndexPath:, toggle the selection state in your array for the tapped row and set the tapped cell's accessory type to checkmark or none, depending on the selection state.

GridView displaying old data

On the Select event on the Grid View I went to the next page. After some time if I want to use the same page I got the same data on that page; how could I get out of this problem?
I am not sure to what you are asking, but I guess you keep getting the same results no matter what select button you click.
Try to set EnableViewState="False" on grids and see what happens.
