Multiple UITextfield Create Dynamically in iphone sdk - iphone

Question

I have to create a multiple textfield dynamically on scrollview in ipad app. textfield created successfully and i use popup view on clicked textfield but when i clicked on textfield i dont get the Tag of Textfield. i get tag of last textfield so i cant set the text on the current textfield.
Following code i used...
int j = 430;
int k = 413;
int RB = 423;
for (int i=0; i<[appDelegate.questions count]; i++) {
imgTxtQue = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"textbox.png"]];
imgTxtQue.frame = CGRectMake(267, k, 490, 60);
// UIImageView *imgRatingBtn = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#""]];
// imgRatingBtn.frame = CGRectMake(633, RB, 102, 39);
//ratingButton1.hidden = NO;
ratingButton1 = [[UIButton alloc] initWithFrame:CGRectMake(633, RB, 102, 39)];
[ratingButton1 setImage:[UIImage imageNamed:#"rating_selected.png"] forState:UIControlStateNormal];
txtQuestions = [[UITextField alloc] initWithFrame:CGRectMake(296, j, 429, 24)];
//txtQuestions.tag = i;
[txtQuestions setTag:i];
NSLog(#"%d", txtQuestions.tag);
txtQuestions.delegate = self;
[txtQuestions setPlaceholder:[[appDelegate.questions objectAtIndex:i] objectForKey:#"question"]];
txtQuestions.borderStyle = UITextBorderStyleNone;
// txtQuestions.background = imgTxtQue.image;
[scrView addSubview:imgTxtQue];
[scrView addSubview:ratingButton1];
[scrView addSubview:txtQuestions];
j = j+50;
k = k+50;
RB = RB+50;
}
-(void)loadQuestion
{
txtQuestionOne.hidden=NO;
imgTxtQue.hidden=NO;
CGRect aFrame1 = imgTxtQue.frame;
aFrame1.size.width = aFrame1.size.width + 200;
// aFrame.size.height = newHeight;
NSString *strQue = [NSString stringWithFormat:#"%#",[[appDelegate.questions objectAtIndex:0] objectForKey:#"question"]];
CGSize newSize1 = [strQue sizeWithFont: [UIFont fontWithName: #"TrebuchetMS" size: 12] ];
if (strQue.length > 42) {
imgTxtQue.frame = CGRectMake(267, 413, newSize1.width+353, 60);
[txtQuestionOne setFrame:CGRectMake(294, 430, newSize1.width+350, 24)];
ratingButton1.frame = CGRectMake(855, 423, 102, 39);
ratingLabel1.frame = CGRectMake(900, 430, 42, 21);
}
[txtQuestionOne setPlaceholder:[[appDelegate.questions objectAtIndex:0] objectForKey:#"question"]];
appDelegate.dynamicQues =[[appDelegate.questions objectAtIndex:0] objectForKey:#"question"];
NSLog(#"current q1 %#", [[appDelegate.questions objectAtIndex:0] objectForKey:#"question"]);
if ([[[appDelegate.questions objectAtIndex:0] objectForKey:#"permission"] isEqualToString:#"1"]) {
ratingButton1.hidden=NO;
ratingLabel1.hidden=NO;
}
}
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
BOOL editing=YES;
for (UIImageView *img in ViewPost.subviews)
{
if ([img isKindOfClass:[UIImageView class]])
{
if (img.tag==textField.tag)
{
[img setImage:[UIImage imageNamed:#"Redtextbox.png"]];;
}
else{
if (img.tag!=0) {
if (img.tag != 10) {
[img setImage:[UIImage imageNamed:#"textbox.png"]];
}
else
{
[img setImage:[UIImage imageNamed:#"inputbox.png"]];
}
}
}
}
}
if (textField==txtcategory) {
[textField resignFirstResponder];
appDelegate.category=YES;
editing=NO;
touchflag=1;
[self performSelectorOnMainThread:#selector(CategoryListClick) withObject:nil waitUntilDone:YES];
//[self CategoryListClick];
return NO;
}
if (textField==txtsubcategory) {
appDelegate.category=NO;
editing=NO;
[self performSelectorOnMainThread:#selector(CategoryListClick) withObject:nil waitUntilDone:YES];
}
if (txtQuestions.tag) {
// if (textField==txtQuestions) {
editing=NO;
index=txtQuestions.tag;
NSLog(#"%d",txtQuestions.tag);
touchflag = 1;
[self performSelectorOnMainThread:#selector(loadAnswers) withObject:nil waitUntilDone:YES];
// }
}
-(void)loadAnswers{
if (touchflag==1) {
[Name resignFirstResponder];
[Email resignFirstResponder];
[txtCityCode resignFirstResponder];
[txtcategory resignFirstResponder];
[txtTitle resignFirstResponder];
[txtQuestions resignFirstResponder];
[txtsubcategory resignFirstResponder];
SubcategoryPopViewController *objPopview = [[SubcategoryPopViewController alloc]initWithNibName:#"SubcategoryPopViewController" bundle:nil];
objPopview.delegate = self;
objPopview.index=txtQuestions.tag;
popView =[[UIPopoverController alloc]initWithContentViewController:objPopview];
[self RescheduleTimer];
[popView presentPopoverFromRect:imgTxtQue.frame inView:ViewPost permittedArrowDirections:0 animated:NO];
[popView setPopoverContentSize:CGSizeMake(376, 260)];
}
}
-(void) didSelectAnswer{
touchflag=0;
[popView dismissPopoverAnimated:YES];
[self RescheduleTimer];
if (appDelegate.ansDynamic==YES) {
// txtQuestionOne.text=appDelegate.answerOne;
if (txtQuestions.tag) {
txtQuestions.text = appDelegate.answerDynamic;
}
appDelegate.ansDynamic=NO;
questionIndex=txtQuestions.tag;
if (![ratingButton1 isHidden]) {
ratingButton1.enabled=YES;
RatingPopViewController *objPopview = [[RatingPopViewController alloc]initWithNibName:#"RatingPopViewController" bundle:nil];
objPopview.index=txtQuestions.tag;
objPopview.checkedCell=ratingLabel1.text;
objPopview.QuestionText=appDelegate.answerDynamic;
objPopview.delegate=self;
popSweepStakes =[[UIPopoverController alloc]initWithContentViewController:objPopview];
[popSweepStakes presentPopoverFromRect:ratingButton1.frame inView:ViewPost permittedArrowDirections:UIPopoverArrowDirectionRight animated:YES];
[popSweepStakes setPopoverContentSize:CGSizeMake(300, 400)];
}
return;
}
In the above code i get the tag correctly but when i use tag on other mathod then i only get the last textfields tag.
Thanks,

Answer 1

You overwrite txtQuestions variable.
Declare a class attribute like this NSMutableArray * _textFieldArray. (It's import declare a NSMutableArray object for add your textField).
In the init method of your class allocate and init your array: _textFieldArray = [[NSmutableArray alloc]init].
In your for statement use the following code for allocate a textField:
UItextField * txtQuestions = [[UITextField alloc] initWithFrame:CGRectMake(296, j, 429, 24)];
After setting all your property on txtQuestions object, add it to the array
[_textFieldArray addObject:txtQuestions]
When you need for a textfield use this code:
[_textFieldArray objectAtIndex:txtQuestions.tag]
Is it Clear?
