I feel like this is a fairly easy question, but I've tried for hours and can't seem to get it. I'm trying to create an app that calculates different equations that are critical to my job. Essentially, I've grouped the calculations into categories using nested TableViewControllers. This part works.
The part I am trying to figure out is how to push to a UIViewController so I can actually have the user enter data to do the calculations. For some reason I can't seem to get it to work. I am using Xcode 5 and am using Storyboards.
Really sorry for the long post. I've also included a screenshot of the storyboard at the following link: http://imgur.com/0oSxsR1

If I understand correctly, you want calculatorTableViewController to perform segue to next view.
//when you select a row
-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
//perform a segue
if (indexPath.row == 1)
{
[self performSegueWithIdentifier:#"your_segue_identifier" sender:your_sender];

I am passing NSMutableArray to another a tableview and I want to show it in the table view. My NSMutableArray is as follows
2017-02-07 18:32:24.086 krib[13753:2978659] (
"Balcony.png",
"Utilities Included.png",

"Washing Machine.png",
"Dryer.png",
"Sofa.png",
"TV.png",
"Curtains.png",
"Refrigerator.png",
"Water Heater.png",

)
I send data as,
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:#"segue"]) {
MZFormSheetPresentationViewControllerSegue *presentationSegue = (id)segue;
presentationSegue.formSheetPresentationController.presentationController.shouldApplyBackgroundBlurEffect = YES;
UINavigationController *navigationController = (id)presentationSegue.formSheetPresentationController.contentViewController;
AmennitiesTableTableViewController *presentedViewController = [navigationController.viewControllers firstObject];
// presentedViewController.textFieldBecomeFirstResponder = YES;
presentedViewController.passingString = facilities;
}
and receive data in table view controller,
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Close" style:UIBarButtonItemStylePlain target:self action:#selector(close)];
NSLog(#"%#",self.passingString);
[self.tableView reloadData];
}
I tried showing the mutable array as follows,
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"facilitiesCell";
AmenitiesTableCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
cell.facilitylbl.text = [self.passingString objectAtIndex:indexPath.row];
// Configure the cell...
return cell;
}
But I am not understanding what exactly i am missing to Populate data on the tableview.
I think you are missing to set tableview delegate & datasource.
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Close" style:UIBarButtonItemStylePlain target:self action:#selector(close)];
[self.myTable setDelegate:self];
[self.myTable setDataSource:self];
NSLog(#"%#",self.passingString);
[self.tableView reloadData];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return self.passingString.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"facilitiesCell";
AmenitiesTableCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if(self.passingString.count > 0){
cell.facilitylbl.text = [self.passingString objectAtIndex:indexPath.row];
}
// Configure the cell...
return cell;
}
I'm learning how to make a contact using TableView and navigation controller. I have done the first view page with some cells, but I have some problem with showing the cells on the detail view page of each cell from first view.
when tap the Group A, Group B, Group C on first view page, it goes to the detail view of each cell, it should show cells named A1 A2 A3, B1 B2 B3 or C1 C2 C3 according to my code on detail view page. but it display nothing.
Hope someone can give me some advises, thank you so much!

detail view but nothing displayed
Have you set the delegate and datasource of tableview?
If Yes, check if the datasource methods (numberOfRowsInSection:) are called after you do
groupA = [NSArray arrayWithObjects:#"A1",#"A2",#"A3",nil]; in viewDidLoad method.
I want to make paging swipe left and right using UIScrollView after view detailController.
First, main.m:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
OZDetailViewController *detailViewController = [[OZDetailViewController alloc] initWithNibName:#"OZDetailViewController" bundle:nil];
detailViewController.arrDetailNews = [_arrNews objectAtIndex:indexPath.row];
[self.navigationController pushViewController:detailViewController animated:YES];
OZDetailViewController *arrNewsAll = [[OZDetailViewController alloc] initWithNibName:#"OZDetailViewController" bundle:nil];
arrNewsAll.allNewsArray = _arrNews;
[self.navigationController pushViewController:arrNewsAll animated:YES];
}
When I selected content in tableviewcell, arrDetailNews can loaded in method viewDidLoad() and cellForRowAtIndexPath(). But arrNewsAll cannot loaded in method cellForRowAtIndexPath().
This is my detailViewController.h:
#property (nonatomic, copy) NSArray *allNewsArray;
And detailViewCOntroller.m:
#synthesize allNewsArray;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.tableView.separatorColor = [UIColor clearColor];
NSLog(#"dataArray: %#", allNewsArray);
}
- (int)numberINSectionsInTableView: (UITableView *)tableView
{
return 1;
}
- (int)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 4;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"dataArrayCell: %#", allNewsArray);
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"New Cell"];
}
if(indexPath.row != self.arrDetailNews.count-1){
UIImageView *line = [[UIImageView alloc] initWithFrame:CGRectMake(0, 44, 320, 2)];
line.backgroundColor = [UIColor whiteColor];
[cell addSubview:line];
}
tableView.allowsSelection = NO;
cell.textLabel.text = [NSString stringWithFormat:#"%u", indexPath.row];
if (indexPath.row==0) {
cell.textLabel.text = #"1st";
}
if (indexPath.row==1) {
cell.textLabel.text = #"2nd";
}
if (indexPath.row==2) {
cell.textLabel.text = #"3rd";
}
return cell;
}
If allNewsArray can loaded in cellForRowAtIndexPath() I can continue next step for paging with UIScrollView. Note, numberOfRowsInSection I set to 4 because I need 4 rows (custom view).
Assuming you setup your delegate & dataSource outlets correctly from xib/storyboard, you still need to specify the number of rows per section (or number of sections).
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return allNewsArray.count;
}
Alternatively, the method for number of sections is:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView;
I've ran into a problem. I have a TableView that I have created programmatically which does not display the TextView that I have added corresponding to the rows of TableView. I cannot find a solution to this on Stack Overflow.

#interface MasterTableViewController ()

You should init your cell
And... You have a common way for initiate your variables. This one should be suitable for you. That method calls before all others and you can initiate your variables here:
-(id)initWithStyle:(UITableViewStyle)style
{
if (self = [super initWithStyle:style])
{
someArray = [NSMutableArray array]; //init the array
}
return self;
}
i wanted to make collapsable/expandable tableview in which i have two headers product and services and each of them contains 10+ object with custom cell which contains checkmark on left side and label. i check for the tutorials but most of them are using .xib while my project is based on storyboard.
i check these tutorials, can anyone please help me regarding this.
