I have an array filled with dictionaries.
Each dictionary have strings like title, info and date.
Cells in the table are arranged by the date from the dictionary.
What should I do to make it show the cell as active if the date field in dictionary=current date or closest date in the future?
Thanks in advance! I'd really appreciate your help!
I am assuming that you want to somehow highlight the current date. A simple thing would be to select the cell using [cell setSelected:YES animated:YES]. An other thing would be setting the accessoryType to UITableViewCellAccessoryCheckmark ([cell setAccessoryType:UITableViewCellAccessoryCheckmark]). If you don't like these approaches, you can still create a custom UITableViewCell with support of some sort of highlighting, like showing an arrow in the cell.

I would like to know if there is any sneaky way of getting a UITableViewCell to appear at the beginning of a UITableView no matter what the array that is going to populate the tableview contains?
I am having issues where I would like to have a "select all" cell at the top of the tableview but currently having issues trying to adjust the arrays I have going into the tableView:cellForRowAtIndexPath:
Not sure of your end goal, but there are many ways some easier (sneaky ways) than others depending on your needs. It sounds like your items are fairly static, so you can just insert them before you display or update the table row.
say you have a datasource called self.items and you did something to get data. Maybe in your app you are round tripping to some data source based upon input, like sort selectors or from the search bar delegate.
try something like this in the area where you load your datasource.
NSString *myCustomObject = #"Jump To Songs";
self.items = [self getGetMovieList];
[self.items insertObject:myCustomObject atIndex:0];
[self.tableView reloadData];
Another easy way would be to add sections to your table and just make the first section your navigation items.
Note: you may need to handle the actions in didSelectRowAtIndexPath......
there you go, not so sneaky, but pretty simple.
be well
You can make two types of UITableViewCell, then return the "select all" one if indexPath.row == 0.
On the other hand, how about just make a UIView for the "select all" functionality, and set it as the tableHeaderView of your table view?
i have 2 test fields with from Date and to Date and a button. when the button is tapped the validation should take place then if the valid dates are given i want the data to be displayed in the tableView.
I am very much confused on where to write this code. Either in cellForRowAtIndexPath or in the IBAction method for the button?.
if its written in cellForRowAtIndexPath the validation is taking place when the view is loaded.and if its written in the method where should i write the code for displaying the data.
if i'm not wrong ,
it is better to do it in IBAction and then if you are setting values , if you think you are doing them right then the only thing you need to call is :
["your-table-view" reloadData];
then it will be done i guess..
i hope this helps..
Actually i used the pickerView for display My database value containing Name, SSN, Research Area etc. Now I need to search in each component of pickerview, like Name,SSN using SearchBar is it Possible?
If I understand you right, you want to filter the rows of the components when the searchtext changed.
You can have a NSArray for each component to populate it with: In – searchBar:textDidChange: you can check which entries in your arrays fit to the search text and add it to a array, that you will use to fill the picker. Don't forget to either call [aPickerView reloadAllComponents] or [aPickerView reloadComponent:i], this will tell the picker to draw itself again.
My data is sourced in a plist and displayed in a tableview with navigation bar.
I want to load the subview with the cell that was clicked.
I know this would set it correct, but I'm not sure how to implement indexPath in the viewDidLoad method?
self.navigationItem.title = [[self.exerciseArray objectAtIndex:indexPath.row]objectForKey: #"name"];
You have an array of Dictionary With you. Now IndexPath is seen called in TableView delegate methods. I doesn't mean that you can't create one. Create an NSIndexpath obect and assign the indexes parameters and send it to the function which contains the above code( separate the code which sets the title from the Cell for row at index path).
But the problem is as I see, You want to show only a specific set of data in dictionary which is stored in an Array. The real problem is You should know which the index of the Array you want to load. to the title and the tableview. If you can know that then its solved.

I am beginner iphone developer I want created table in programatically. In the table we take more than 20 row. But i have some problem that after 11th row the same value repeated.
plz help me with code and other method
You may want to look at this question which is the same problem. In that case, the person was setting the text of the cell only when creating a new cell (when nil was returned from [tableView dequeueReusableCellWithIdentifier:].) It needs to be set every time the tableView:cellForRowAtIndexPath: is called.
when you use reuseIdentifyer, the new cell to display is the cell that has just disappeared. so it will contain all the data from the disappeared cell. for example, if the cell, that has just disappeared, has detailDisclosureIndicator, the new cell will have it too even you don't set it.
