I have some textfield values & uiimage stored in one view controller. I have tableview in another view controller . I want store values using nsuserdefaults in tableview and retrieve using nsuserdefaults then want to add rows dynamically as user enters?

Answer 1

Let's say you have an NSMutableArray of this data like this:
NSMutableArray *cellLabelValues = [[NSMutableArray alloc] initWithObjects: #"1",#"2",#"3",nil];
In your tableView delegates do this:
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return cellLabelValues.count;
}
You must have a button or something to receive user's intent to add new cells. Lets assume it calls this method:
-(void) addNewCell:
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Enter New Value"
message:#" "
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"OK", nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
}
And write the delegate of UIAlertView. Make sure you have made your ViewController to be UIAlertViewDelegate:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 1) {
NSString *value = [alertView textFieldAtIndex:0].text;
[cellLabelValues addObject:value];
[tableView reloadData];
}
}
What happens here is, user taps new cell button. It takes entry from user. Then it reloads the table after adding it to your array. When it reaches numberOfRowsInSection delegate method, it sees that the array is now incremented by 1. So it will show one extra cell.

You can maintain a Mutable array with strings from textfield.
Then based on the array.count you can get the size of array.
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return array.count
}
and also don't forget to reload table view.

Answer 3

Suppose you have two UIViewControllers ViewController1 with UITextFields and ViewController2 with UITableView
Now in ViewController2 declare an NSMutableArray *dataArray;
and add record in it from ViewController1 before moving to ViewController2
In ViewController2
use this function
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return dataArray.count;
}
It will help.
