POUITableViewController to display a persons information -- need assistance with editing
text
Body
copied!<p>I have a UITableViewController that is being called when the user clicks on a row in the previous ViewController (which shows all contacts for the app). </p> <p>This view that I'm working on needs to show detailed information. Right now I'm only working with </p> <ul> <li>First Name</li> <li>Last Name</li> <li>Home Email</li> <li>Work Email</li> </ul> <p>Eventually I will add in much more information but this is my proof of concept data I want to work with.</p> <p><img src="https://i.stack.imgur.com/bOTTx.png" alt="Here is what the Scene looks like"></p> <p>The information passed into this scene is populated from a <strong>Person</strong> object.</p> <p>I'm trying to figure out how I can do a few things when the user hits Edit.</p> <ol> <li>I need to be able to show all the information that can be entered. So if the Person object only has "First Name", "Last Name" defined, then I also want to show that the other two email fields are available.</li> <li>To piggy back off of the first issue I'm having, I would like to hide the fields if they are not present (outside of editing)</li> <li>I want to be able to delete a field and be able to delete the whole Person object (maybe a button at the bottom like iOS7 contacts).</li> </ol> <p>I just need some assistance or a push in the right direction.</p> <hr> <p>Here is the code that I have for this ViewController</p> <pre><code>// // SingleContactViewController.h // General view to display a single person record #import <UIKit/UIKit.h> #import "PublicContactsViewController.h" #import "Person.h" @interface SingleContactViewController : UITableViewController <ADBannerViewDelegate> @property (nonatomic, strong) Person *person; @property (strong, nonatomic) IBOutlet UIBarButtonItem *editButton; @property (nonatomic, assign, getter=isPrivate) BOOL private; @property (strong, nonatomic) IBOutlet UITextField *firstNameTextField; @property (strong, nonatomic) IBOutlet UITextField *lastNameTextField; @property (strong, nonatomic) IBOutlet UITextField *homeEmailTextField; @property (strong, nonatomic) IBOutlet UITextField *workEmailTextField; @end </code></pre> <hr> <pre><code>// // SingleContactViewController.m // #import "SingleContactViewController.h" #import "Person.h" @interface SingleContactViewController () @property (strong, nonatomic) IBOutlet ADBannerView *banner; @property (nonatomic, assign) BOOL isEditing; - (IBAction)popBackToContacts:(UIBarButtonItem *)sender; - (IBAction)editContact:(UIBarButtonItem *)sender; @end @implementation SingleContactViewController - (void)viewWillAppear:(BOOL)animated { self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:.498 green:0 blue:.0 alpha:1]; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. _banner.delegate = self; NSLog(@"SingleContactView - viewDidLoad method: person = %@",self.person.firstName); self.firstNameTextField.text = [self.person.firstName copy]; self.lastNameTextField.text = [self.person.lastName copy]; self.homeEmailTextField.text = [self.person.homeEmail copy]; self.workEmailTextField.text = [self.person.workEmail copy]; } #pragma mark - Editing Methods - (void)setEditing:(BOOL)editing animated:(BOOL)animated { NSLog(@"Entered setEditing"); [super setEditing:editing animated:animated]; [self.tableView setEditing:editing animated:animated]; if (editing == YES){ // Change views to edit mode. } else { // } } - (IBAction)editContact:(UIBarButtonItem *)sender { NSLog(@"User pressed 'Edit' button.
