On pressing a disclosure button i want to push another view containing the details of the cell from which the disclosure button was pushed. I have the code below but dont know why it doesnt work. On clicking the disclosure button the programme does go into the tableView:accessoryButtonTappedForRowWithIndexPath function but doesnt bring up the view.
-(void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath{
self.detailController.title = #"Single Contact";
NSMutableArray *array = [[NSMutableArray alloc] init];
if (indexPath.section == 0) {
array = self.friends;
}
else if (indexPath.section == 1) {
array = self.members;
}else{
array = self.invite;
}
NSDictionary *data = [array objectAtIndex:indexPath.row];
NSString *name = [data valueForKey:#"firstName"];
self.detailController.message = name;
[self alertMeWithString:#"THIS STRING"];
[self.navigationController pushViewController:self.detailController animated:YES];
}
-(id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if(self){
self.detailController = [[DSZContactDetailViewController alloc] init];
}
return self;

I have added my delegate method and
I have a UITableView with a list of names. It has sections with an alphabetical index on the right hand side (see picture).
My program crashes whenever I enter a first character in the search field. I get the following error:
UpdateSearchResultsForSearchController
[__NSArrayM objectAtIndex:]: index 0 beyond bounds for empty array'
Understand I am trying to access an empty array, in the method UpdateSearchResultsForSearchController.
The program crashes in the last line of the method.

The problem is that, your are removing all objects at this line
[self.tableSectionsAndItems removeAllObjects];
and you have commented the lines, which again feels that array, just above the lines which you mentioned in your question. so, uncomment the following lines
//NSDictionary *namesByGroup = [Item fetchItemNamesByGroupFilteredBySearchText:searchText ////inManagedObjectContext:self.managedObjectContext];
//self.tableSectionsAndItems = [[[NSArray alloc] initWithObjects:namesByGroup, nil] mutableCopy];
And in numberOfRows Method, you are accessing the object at index on empty array that leads to crash.
[self.tableSectionsAndItems objectAtIndex:section];
So, uncomment those two lines above, in the following method and it will fix.
-(void)updateSearchResultsForSearchController:(UISearchController *)searchController

I'm working on an application in which I have a UITableView, two arrays and one UISegmentedControl. Now I need to when the UISegmentedControl value is 0 loaded in the UITableView data from the array one, and when UISegmentedControl has value 1 loaded data from array two. Simply, I need to switch the data to be loaded into UITableView from arrays. I tried to use a bool, but it does not work, I also think that it's not ideal.
Here is my code:
- (void)viewDidLoad
{
[super viewDidLoad];
allTableData = [[NSMutableArray alloc] initWithObjects:
[[Food alloc] initWithName:#"BWM" andDescription:#"Auto" andDefinice:#"Osobni"],nil ];
allTableData2 = [[NSMutableArray alloc] initWithObjects:
[[Food alloc] initWithName:#"Renault" andDescription:#"Dodavka" andDefinice:#"Velka"],nil ];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
long rowCount;
if(self.isSwich == false)
rowCount = allTableData.count;
else
rowCount = allTableData2.count;
return rowCount;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
Food* food;
if(self.isSwitch == false)
{
food = [allTableData objectAtIndex:indexPath.row];
}
else
{
food = [allTableData2 objectAtIndex:indexPath.row];
}
cell.textLabel.text = food.name;
cell.detailTextLabel.text = food.description;
return cell;
}
-(IBAction)switchdata:(id)sender
{
if(self.myswitcher.selectedSegmentIndex == 0)
{
isSwitch = FALSE;
}
else
{
isSwitch = TRUE;
}
}
You are missing a call to reloadData in the witchdata: implementation. Adding this call will fix the problem.
I also think that it's not ideal.
That's right. Rather than storing a flag that says which array to use for your data source, store the array itself. This would eliminate all the ifs on the isSwitch property:
// Declare this as an instance variable, and use it
// in your data source methods.
NSArray *theSource;
- (void)viewDidLoad {
[super viewDidLoad];
allTableData = [[NSMutableArray alloc] initWithObjects:
[[Food alloc] initWithName:#"BWM" andDescription:#"Auto" andDefinice:#"Osobni"],nil ];
allTableData2 = [[NSMutableArray alloc] initWithObjects:
[[Food alloc] initWithName:#"Renault" andDescription:#"Dodavka" andDefinice:#"Velka"], nil];
theSource = allTableData;
}
-(IBAction)switchdata:(id)sender {
if(self.myswitcher.selectedSegmentIndex == 0) {
theSource = allTableData;
} else {
theSource = allTableData2;
}
[myTable reloadData];
}
Alternatively you could make isSwitch an integer, and use it as an index into an array that has your allTableData at index zero and allTableData2 at index one:
NSArray *sources;
int sourceIndex;
// Use sources[sourceIndex] as the current source
- (void)viewDidLoad {
[super viewDidLoad];
allTableData = [[NSMutableArray alloc] initWithObjects:
[[Food alloc] initWithName:#"BWM" andDescription:#"Auto" andDefinice:#"Osobni"], nil];
allTableData2 = [[NSMutableArray alloc] initWithObjects:
[[Food alloc] initWithName:#"Renault" andDescription:#"Dodavka" andDefinice:#"Velka"],nil ];
sources = #[allTableData, allTableData2];
sourceIndex = 0;
}
-(IBAction)switchdata:(id)sender {
sourceIndex = self.myswitcher.selectedSegmentIndex;
[myTable reloadData];
}
Firstly, in your switchData: method - use self.switch to access its setters,getters.
Secondly, Rather than using a bool value to track segment value, use the direct segment value.
Replace your self.switch value with self.switcher.selectedSegmentIndex in the table view delegate,datasource methods.
Finally, reload table view in your switchData: method.
I'm trying to create a simple create, display and edit contacts in Xcode 4.2 for iOS using AddressBook, so far I have done the create and display function. Now I need to implement edit function along with display. Now when I click on display it displays all the contacts and when I click on any name it shows info with a back button and a cancel button. I need to change the cancel button to edit and call the edit functionality. Below is the code of ViewController.m which I have done so far. Appreciate if u could give me a solution.

return aCell;
}

I can get the desired result if I code like this in the tableview didselectRowAtIndexPath property, but I want to implement and integrate this code inside my displayContacts method instead of tableview here. Because this method is for initial screen for display and create contacts. Is there any other way that I could get the indexPath of the current selected names once I am inside the display contacts???
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
ABPersonViewController *DVC=[[ABPersonViewController alloc]init];
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL,NULL);
NSMutableArray *allPeople = (__bridge NSMutableArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);
int nPeople = ABAddressBookGetPersonCount(addressBook);
for(int i=0;i<nPeople;i++) {
ABRecordRef person = (__bridge ABRecordRef)([allPeople objectAtIndex:i]);
NSString *name = [self.contactAdd objectAtIndex:indexPath.row],*name2;
if(ABRecordCopyValue(person, kABPersonFirstNameProperty) != NULL) {
name2 = [[NSString stringWithFormat:#"%#", ABRecordCopyValue(person, kABPersonFirstNameProperty)]
stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
name2=[name2 stringByAppendingString:#" "];
name2=[name2 stringByAppendingString:[[NSString stringWithFormat:#"%#", ABRecordCopyValue(person, kABPersonLastNameProperty)]
stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]];
}
if([name isEqualToString:name2])
{
DVC.displayedPerson=person;
DVC.allowsEditing=YES;
[self.navigationController pushViewController:DVC animated:YES];
break;
}
}
}
-(BOOL)peoplePickerNavigationController:
(ABPeoplePickerNavigationController *)peoplePicker
shouldContinueAfterSelectingPerson:(ABRecordRef)person {
[peoplePicker dismissModalViewControllerAnimated:NO];
ABPersonViewController *picker = [[ABPersonViewController alloc] init];
picker.personViewDelegate = self;
picker.displayedPerson = person;
// Allow users to edit the person’s information
picker.allowsEditing = YES;
[self.navigationController pushViewController:picker animated:YES];
return YES;
}
Got the solution with help of this function, but now stuck in adding delete function :P
I have an iPhone app that I'm wanting to make a universal app and implement a split view on the iPad. I have the master view set up so that when the user selects a row, the master view goes to another table view. When a row is selected in that table view, I want the detail view to show my web view. This all works but the issue I'm having is when the web view shows on the detail view, it is just getting added to the navigation stack instead of just replacing what is currently there. This makes it so that the user has to press the back button on the detail view navigation bar in order to make another selection in the master view. If another selection is made in the master view without pressing the back button on the detail view, the app crashes.
I need to figure out how to have the web view not get added to the navigation stack of the detail view and instead replace the current detail view.

I want developed a similar alarm application to remind user send message, and my question is I want get user field in data like numbers, message and date to table view by array.
I do this use tabbar controller,my first view is gave to user field in all data and check save button. My second view is table view to remind user.
Now I can save the data in NSMutableArray by one time only, where I save the data again, the old data with replace. Anyone know how to do this?
My code here.
Here is save button for another view.
I call FirstView
- (IBAction)SaveAll:(id)sender{
if(numText.text == nil || textView.text == nil || Selectime == nil){
NSLog(#"error becos value null");
UIAlertView *errorview = [[UIAlertView alloc]initWithTitle:#"Error Info" message:#"You nomber , message text or date no input or select.Pls fill in all. "delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[errorview show];
[errorview release];
}else{
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
if (localNotif == nil)
return;
DataClass *obj=[DataClass getInstance];
localNotif.fireDate = obj.showdate;
NSString *getdate = [obj.showdate description];
[defaults setObject:getdate forKey:#"date"];
NSLog(#"localNotif = %#", localNotif.fireDate);
localNotif.timeZone = [NSTimeZone localTimeZone];
obj.showdate = nil;
NSString *getnum =numText.text;
[defaults setObject:getnum forKey:#"keyToLookupString"];
// Notification details
// localNotif.alertBody = [eventText text];
NSString *getmessage = self.textView.text;
[defaults setObject:getmessage forKey:#"message"];
localNotif.alertBody = self.textView.text;
NSLog(#"alertBody message = %#",localNotif.alertBody);
// Set the action button
localNotif.alertAction = #"Send Now?";
localNotif.soundName = UILocalNotificationDefaultSoundName;
localNotif.applicationIconBadgeNumber = 1;
// Specify custom data for the notification
NSDictionary *infoDict = [NSDictionary dictionaryWithObject:#"someValue" forKey:#"someKey"];
localNotif.userInfo = infoDict;
// Schedule the notification
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
[localNotif release];
numText.text = #"";
textView.text = #"";
Selectime.text = #"";
self.textView.placeholder = NSLocalizedString(#"Event Here....",);

Replace the viewDidLoad with viewWillappear...viewDidLoad is called only once when you loaded the view so you cant able to replace the array. viewWillappear is called everytime when the view is appeared on the screen...
EDIT:afer seeing the comments.
keep the viewdidload as it is . add these codes to your application.
