    <p>I need to take this data structure, an nsmutablearray, and iterate through each index and print each field into a textfield. every "forward" button increments the data ahead and "backwards" goes back. I am having a really hard time getting this to work properly, does anyone know what im doing wrong. Keep in mind, the object held in the array, called info_holder, is an object that holds 3 strings and one counter:</p> <pre><code>#import "ZDViewController.h" @implementation ZDViewController @synthesize password; @synthesize count; @synthesize web; @synthesize username; @synthesize header; - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } #pragma mark - View lifecycle - (void)viewDidLoad { [super viewDidLoad]; NSMutableArray *array = [[NSMutableArray alloc] init]; info_holder *set1 = [[info_holder alloc] init]; info_holder *set2 = [[info_holder alloc] init]; info_holder *set3 = [[info_holder alloc] init]; info_holder *set4 = [[info_holder alloc] init]; info_holder *set5 = [[info_holder alloc] init]; [set1 SetUser: @"info1"]; //temporary information until big is fixed [set1 SetPass: @"info2"]; [set1 SetKey: @"webinfo1"]; [set1 SetCount: 0]; [set2 SetUser: @"info3"]; [set2 SetPass: @"info4"]; [set2 SetKey: @"webinfo2"]; [set2 SetCount: 0]; [set3 SetUser: @"info5"]; [set3 SetPass: @"info6"]; [set3 SetKey: @"webinfo3"]; [set3 SetCount: 0]; [set4 SetUser: @"info7"]; [set4 SetPass: @"info8"]; [set4 SetKey: @"webinfo4"]; [set4 SetCount: 0]; [set5 SetUser: @"info9"]; [set5 SetPass: @"info10"]; [set5 SetKey: @"Webinfo5"]; [set5 SetCount: 0]; } - (void)viewDidUnload { [self setHeader:nil]; [self setWeb:nil]; [self setPassword:nil]; [self setCount:nil]; [self setUsername:nil]; [super viewDidUnload]; } - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; } - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; } - (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; } - (void)viewDidDisappear:(BOOL)animated { [super viewDidDisappear:animated]; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown); } - (IBAction)increment:(id)sender { if(username.text==@"test") username.text=@"test2"; else username.text=@"test"; //this should print a new username NSSTRING, wedsite NSTRING, password NSTRING and INEGER counter, heald in the info_holder object, incremented per click backwards } - (IBAction)decrement:(id)sender { } - (IBAction)Inc:(id)sender { } - (IBAction)textFieldDoneEditing:(id)sender { [sender resignFirstResponder]; } - (IBAction)backgroundTap:(id)sender { [web resignFirstResponder]; [username resignFirstResponder]; [count resignFirstResponder]; [password resignFirstResponder]; } @end </code></pre> <p>and my main is:</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import "ZDAppDelegate.h" #import "info_holder.h" int main(int argc, char *argv[]) { @autoreleasepool { return UIApplicationMain(argc, argv, nil, NSStringFromClass([ZDAppDelegate class])); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
