Since there is no pre-existing component for creating a combobox (or select box) as seen on webpages through Safari, can someone provide an example or pre-existing 3rd party component of creating one?
I don't think this is hard to do.
In a view controller you have a UITextField and a UITableView. Assign the view controller to be the delegate of the both controls, plus the data source of the table.
Implement the UITextField delegate method textField:shouldChangeCharactersInRange:replacementString: in your controller. This intercepts the changes as they are being typed in your text field. In this method, iterate through your list of possible options and store the matches in an NSMutableArray instance variable on your view controller. Then call [myTableView reloadData].
Have your table cells generated from the array of matches you previously stored.
It should be pretty straightforward and shouldn't take much code at all beyond a few delegate methods to get working.

I want to have the ability to allow the user to fill out a profile, almost like the notes app and then when they are done it adds it to the UITableViewCell and displays certain parts of what they filled out on the Cell..Then they can obviously repeat this action..
I am not sure where to look for a tutorial on this or what this may be called, anyone have any suggestions?
Five simple steps :
1)Design how form is gonna look like and your tableview.
2)Make the form using a sample UIviewcontroller layout your components using xib or
storyboard
3) Embed your UIViewcontroller designed in step 2 into a UINavigationViewController
This helps you to transition from your form to UITableView
4) Design your UITableViewController and put a back button on UINavigationBar to allow user to go to previous view controller.
5) Connect UIViewController to UITableViewController
-(void)submitButtonPressed:(id)sender{
UITableViewController *tvc = [[UITableViewController alloc] initWithNib:#"your view controller name"];
// pass data to UITableViewController
tvc.userdata = self.userdata;
[self.navigationController pushviewController:tvc];
}

I have problem about accessing class, and i ve been looking for solution, couldnt figured out yet.
I have 3 classes:
1 - ViewController
2 - XmlParser
3 - AllDeals,
When i open app, ViewController uses XmlParses class, and XmlParser class parses xml file and stores information into NSMutableArray in the XmlParser Class.
I would like to access that NSMutableArray(in XmlParser class) and all information that it stored already from AllDeals class. I cannot split up Xml file again. it s taking too much time.
When i tried to access nothing comes. I have tried many things.
How am i gonna point or access that class or NSMutableArray...
Thank you for your helps.
Have you tried to use shared instance of XmlParser Class ? If Not then make shared instance whenever you want to use this class and access that NSMutableArray with the help of XmlParser Class shared instance.
if you're aware about the delegates then you can pass values over delegate at the success of your parsing else create one NSMutableArray into your 1-ViewController globally and take advantage of it by passing the parent of viewController to XmlParser then you'll have filled NSMutableArray of your desired output and access it further more.

passing response data from one class to another class
//i want to pass "reside:15" to another View controller.
2013-08-16 14:29:57.273 blabby[1432:1a603] Login response:{"response":"success","resid":15}
add an class
Constant.h
in constant.h
take an string like
NSString *str;
import constant class into your class and than str =your response data;
and use it into another class.
This is an NSDictionary. As with any NSObject, you can make it a property of source view controller and access it in another view controller.
Read it in detail: Coordination between View Controllers.
create a dictionary in the view controller you want to hold that data,while pushing that view controller you can take that data and use it.It is called as design patterns.

WARNING: Using legacy cell layout due to delegate implementation of tableView:accessoryTypeForRowWithIndexPath: in <Settings: 0x250c60>. Please remove your implementation of this method and set the cell properties accessoryType and/or editingAccessoryType to move to the new cell layout behavior.
Here,
accessoryTypeForRowWithIndexPath is deprecated in iPhone OS 3.0.
Instead set like this.
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;

I've heard varying things about whether or not creating a Subclass of UIWebView is allowable. Can someone link me to any documentation that clarifies this one way or another?
There are mixed messages coming from Apple on this.
The docs do say not to subclass as BoltClock noted. However, one of the presentations from WWDC 2011, Rich Text Editing in Safari on iOS, suggests subclassing. It appears to be the only way to add custom UIMenuItems.
From the slides:
// For your UIWebView subclass:
- (void)bold:(id)sender {
[self stringByEvaluatingJavaScript:#”document.execCommand(‘Bold’)];
}
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {
if (action == #selector(bold:))
return YES;
return [super canPerformAction:action withSender:sender];
}
I need functionality other than Copy and Paste in my app so I'll be subclassing.
Under Subclassing Notes of the UIWebView reference, all it says is:
Subclassing Notes
The UIWebView class should not be subclassed.
It doesn't say why. I would guess that it's to maintain the integrity of the underlying WebKit control or something, I dunno.
