Getting the value of textfields which are created during runtime
i am building a form when a button is pressed. When the button has been pressed, an ASIHTTPRequest to a server get send. This server is returning a XML document, which i am building a form of.
the method, which is building up a form looks like this:
- (void) traverseElement:(TBXMLElement *)element {
static CGFloat y = 300.0f;
static CGFloat dynamicHeight = 400.0f;
do {
if ([[TBXML elementName:element] isEqualToString:@"wcqQuestionText"]) {
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(75, y, 200, 50)];
label.text = [TBXML textForElement:element];
[scrollView addSubview:label];
scrollView.contentSize = CGSizeMake(768, dynamicHeight);
[formulierText removeFromSuperview];
[label release];
y += 50.0f;
dynamicHeight += 50.0f;
}
if([[TBXML elementName:element] isEqualToString:@"wcqAnswerValues"]) {
NSString *segmentItemsStr = [TBXML textForElement:element];
NSArray *segmentItemsArray = [segmentItemsStr componentsSeparatedByString:@";"];
UISegmentedControl *answer = [[UISegmentedControl alloc] initWithItems:segmentItemsArray];
answer.frame = CGRec开发者_运维百科tMake(50, y, 400, 40);
[answer addTarget:self action:@selector(textpopup:) forControlEvents:UIControlEventValueChanged];
answer.segmentedControlStyle = UISegmentedControlStyleBar;
[scrollView addSubview:answer];
scrollView.contentSize = CGSizeMake(768, dynamicHeight);
[formulierText removeFromSuperview];
[answer release];
y += 40.0f;
dynamicHeight += 40.0f;
}
if([[TBXML elementName:element] isEqualToString:@"rayonfiliaal"]) {
NSString *rayonFiliaal = [TBXML textForElement:element];
[stringsArray addObject:rayonFiliaal];
}
if([[TBXML elementName:element] isEqualToString:@"filiaal"]) {
NSString *filiaalNaam = [TBXML textForElement:element];
[filiaalArray addObject:filiaalNaam];
}
if ([[TBXML elementName:element] isEqualToString:@"formdata"]) {
y = 300.0f;
dynamicHeight = 400.0f;
}
// if the element has child elements, process them
if (element->firstChild)
[self traverseElement:element->firstChild];
// Obtain next sibling element
} while ((element = element->nextSibling));
}
What i wanted to do is:
If an user fills in the form. I need to save it as a local XML file, with the values in it. What is the best way to achieve this?
You could just store those values in a plist.
This link should show you how to create a plist.
Property List Programming Guide
You can just read each of the values in the label by using this method [label text]
;
For the segmented control you would use the following method
[answer titleForSegmentAtIndex:index]
;
These methods will return a NSString which you can store in a NSDictionary.
Once you have gotten those values, just create the NSDictionary object and call [dictionary writeToFile:pathToDirectory atomically:YES];
