I have a sorted array of strings. I want to group them using tableview section according to first letter similar to iPhone contact.
I am new to iOS can any one help me to do this, The array is retrieving from server.
and also there is a search option for table view
If I understood your question correctly, you want to group and index the items alphabetically?
There is a system class to do that, called UILocalizedIndexedCollation.
Here is a nice tutorial for it:

I have an angular table where table rows and columns are developed from ngfor loop.
As shown in image my table is currently.So when i clicked on save button we need to iterate through each table row and read the values present in each td and need to store them in object.so please tell how to do develop logic in angular.
You can do this using formGroup easily.
See this example,
Table data binding example
Hope this example will give you a better understanding rather than explaining all with words.
So I have did some RnD regarding this already and didn't found anything that will help me to solve this one. So the problem is consider and paper pattern of MCQ question paper and I want to store the each question's answer and at end I need to convert it into JSON data to post it to server. So here all sections are my questions and all rows are my respective answers. For now I've rendered UI and now I'm just concerned about how I can store this data against each question. Also suffering from common problem of repeating dequeue cells. So request to anyone who can guide me in correct way.
So storing each selected index of UICollectionView in [[IndexPath]] array solved this problem for me. Where I initialized this array on view didLoad as per the count of my dataSource array. So my multi-dimensional arrays's outer loop will hold an section per count and inner loop will hold an row count. e.g. [[1,0],[1,2],[3,4],[4,1]] .
A question:
Does anyone know how to get data out of angular ui-grid in the currently displayed sorted order?
I found out how to access data out of the grid using gridApi.grid.rows, but those rows do not appear to be sorted per the current sort order applied to the grid.
I feel like the grid is taunting me...showing me data in sorted order, but refusing to allow me to access it! Help!
Have you tried gridApi.grid.sortByColumn(gridApi.grid.rows)?
O Sean that's hot.
But will that re sort the data? Ideally id just be able to get at the data in its already sorted state.

Load UITableView From CSV Database File?

Closed 8 years ago.
I currently have a list of 1,000 records that I would like to use to populate into a Tableview but I am not sure how to go about doing so. The list is currently in a .txt file. Does anyone have any suggestions as to how to go about populating the table view with this list. Any suggested line of codes would be greatly appreciated.
EDIT: Updating initial question to provide more detail.
Say I have a list of all of the countries in the world that I want to load into a tableview. I have the list in a text file. Is the best approach to insert all of the countries one by one into an array or can I just link the data source of the table view to the .txt file to load the data? Maybe there is another way that I cannot think of. (Sorry if this is not enough detail, I am new to Objective C)
Just read the file using NSFileManager. Once you have the file into a single string object, then you can check this answer in how to split an string obtained from a file.

Then once you have this into an array you can fill your tableView really easy using the UITableViewDataSource Delegate Method
cellForRowAtIndexPath:
just assign to the cell.textLabel.text the value for the array at index indexPath.row provided by the method.

If you can provide some code and the example in how your file looks you could receive more help. Your questions is vague but what I just answer might help to clarify your ideas
I have a list field which contains questions in the first screen and I am passing the selected index of the list to the second screen I am parsing JSON according to the question id. I am parsing the answers for the questions. The question will be 2 types such as single answer and multiple answer. I am displaying an array of Radio button field for single answers and a array of Checkbox field for multiple answers.
If the user selects the answer, I need to store it temporarily and I should show him the answer which he selected when he selects the same question. I don't have idea in this. Can any one guide me in this? I need to do it using sqlite?
you can use Persistent object in BlackBerry. Here is a code sample demonstrates the example to use the persistent-object-in-blackberry
