How to manage UITableView + Dynamic Custom Cell(UIBUtton + UITextField + UIBUtton) Insertion?
I am having problem in managing UITableView. I 'm posting a screenshot here to briefly explain the problem. Image 1 shows the default View when First Time view Appears. When I tap on yellow button(Yellow Button is in a custom table section header view) I open an UIAlertView with table in it like shown in the image 2
And here is the .m file implementation code for analyze the problem
#import "contactsViewController.h"
#import "textFieldCell.h"
#import "SBTableAlert.h"
#import "PhoneFieldCell.h"
#import "DHValidation.h"
#define kTextFieldTag 222
#define kTitleButtonTag 111
#define MAX_LENGTH 20
#define charecterLimit 13
#define PHONE_NUMBER @"0123456789+-"
@implementation contactsViewController
@synthesize currentTextField;
@synthesize choiceList;
@synthesize labelHeaders;
@synthesize selectedIndexPath;
@synthesize aTable;
@synthesize customText;
@synthesize currentSelectionType;
@synthesize phoneList;
@synthesize emailList;
@synthesize otherDetailsList;
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
//Prepare array's for display in table header and in custom alert option table
[self prepareDataForTable];

}
//prepare array's for table

here is your answer http://www.icodeblog.com/2011/01/04/elctextfieldcell-a-useful-tableviewcell-for-forms/
u can also manually do some customization according to your app need
- (void)tableView:(UITableView *)tableView didEndEditingRowAtIndexPath:(NSIndexPath *)indexPath{
[tableView reloadData];
}
加载中,请稍侯......
