When UIPickerView Value changed then table row changed in ios - ios

Question

In my UIview I have UITextField when textfield clicked then I use UIPickerView. Then I select value this value goes in textField.
Now I want when textfield value changed then table row value change.
I have used following code
- (void)viewDidLoad:
{
[super viewDidLoad];
[self loadCriteria];
UILabel * projectDetailLable = [[UILabel alloc] initWithFrame:CGRectMake(0,[topBar bottom],320, 30)];
projectDetailLable.textColor = [UIColor whiteColor];
projectDetailLable.backgroundColor = UIColorFromRGB(0x28a0d8);
projectDetailLable.font = [UIFont boldSystemFontOfSize:16];
projectDetailLable.text = #"Choose Criteria Category:";
projectDetailLable.textAlignment = NSTextAlignmentLeft;
[self.view addSubview:projectDetailLable];
criteriaTextField = [[UITextField alloc] initWithFrame:CGRectMake(2, [projectDetailLable bottom]+2, 316, 30)];
criteriaTextField.borderStyle = UITextBorderStyleLine;
// criteriaTextField.text = #"Health & Well being";
criteriaTextField.font = [UIFont systemFontOfSize:13];
[self.view addSubview:criteriaTextField];
UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = criteriaTextField.frame;
[button addTarget:self action:#selector(launchCriteriaPicker) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
caseStudyTableView = [[UITableView alloc] initWithFrame:CGRectMake(0, [criteriaTextField bottom]+5, 320, self.view.frame.size.height )];
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"7.0")){
[caseStudyTableView setSeparatorInset:UIEdgeInsetsZero];
}
caseStudyTableView.delegate = self;
caseStudyTableView.dataSource = self;
caseStudyTableView.rowHeight = 40;
caseStudyHeaderView.backgroundColor = [UIColor clearColor];
[self.view addSubview:caseStudyTableView];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
[ cell.textLabel setFont:[UIFont boldSystemFontOfSize:13]];
[ cell.textLabel setTextAlignment:NSTextAlignmentLeft];
cell.textLabel.numberOfLines=0;
[ cell.textLabel setTextColor:[UIColor blackColor]];
cell.textLabel.backgroundColor = UIColorFromRGB(0xc8f898);
cell.contentView.backgroundColor = UIColorFromRGB(0xc8f898);
NSLog(#"%#",criteriaNameArray);
cell.textLabel.text = [criteriaNameArray objectAtIndex:indexPath.row];
return cell;
}
how to change table value in IOS.

Answer 1

Use the UITextField Delegate method :
- (void)textFieldDidEndEditing:(UITextField *)textField{
// [criteriaNameArray replaceObjectAtIndex:atIndexToReplace withObject:textField.text];
[self.tableView reloadData]; // Handle the DataSource accordingly in the cellForRowAtIndexPath
}

Answer 2

Try [tableView reloadData]; in pickerview didselect method.

Answer 3

//in view did load listen for text changed notification
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(textFieldChanged:)
name:UITextFieldTextDidChangeNotification
object:yourTextField]
//Reload the table view Whenever the text field changes the text
-(void)textFieldChanged:(id)sender{
[yourTableView reloadData];
}
