UITableViewCell not displaying contents from array - ios

I am working on Fitness(workout) scheduler app with SWRevealView Controller, which offers side bar menu feature.
I have tried to link one cell from the side bar menu to another Tableview controller, where I have set segue between them.
The segue is fine, but it does not display the text data that I have in the mutable array.
MainViewController.h
#import <UIKit/UIKit.h>
#interface MainViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
#property (weak, nonatomic) IBOutlet UIBarButtonItem *sidebarButton;
#end
MainViewController.m
#import "MainViewController.h"
#import "SWRevealViewController.h"
#interface MainViewController ()
#property (nonatomic) NSMutableArray *plans;
#property (nonatomic) NSArray *categories;
#end
#implementation MainViewController
- (void)viewDidLoad {
[super viewDidLoad];
// [UITableView setDelegate:self];

self.plans = #[#{#"name" : #"Week 1-3", #"category" : #"Buff Dudes Workout"}, #{#"name" : #"Week 4-6", #"category" : #"Buff Dudes Workout"}, #{#"name" : #"Week 7-9", #"category" : #"Buff Dudes Workout"}, #{#"name" : #"Week 10-12", #"category" : #"Buff Dudes Workout"}].mutableCopy;
self.categories = #[#"Buff Dudes Workout"];
self.title = #"Workout Programs";
SWRevealViewController *revealViewController = self.revealViewController;
if ( revealViewController )
{
[self.sidebarButton setTarget: self.revealViewController];
[self.sidebarButton setAction: #selector( revealToggle: )];
[self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];
}

if (cell == nil)
{

}
NSDictionary *plans = [self itemAtIndexPath:indexPath];
cell.textLabel.text = plans[#"name"];
return cell;
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
return self.categories[section];
}
#end
I think there is something wrong in my ellForRowAtIndexPath method.

Make sure your tableView dataSource and delegate in IB are connected to files owner (MainViewController).
Add a reference to your tableView and call tableView.reloadData() after setting plans and categories.

Transitioning from UISearchDisplayController ==> UISearchController can't get search bar to show

I have an app that was written for iOS 7 the I need to update as UISearchDisplayController is deprecated for UISearchController.
I have went through several tutorials and tried but I cannot get this to work, however I am close.
I am following this pattern.
The problem I am running into is that the pattern I am following loads the data from a son file into an NSDict object, but my data is in an Array. No problem, I just modified the search to use a predicate (I hard coded something for now, get all records with an E in the name).
But I am getting the following error:
2017-09-12 13:01:41.538 Scoular[7644:1963822] -[employee isEqualToString:]: unrecognized selector sent to instance 0x608000105580

In the SearchResultsTableViewController.m file, at the line
cell.textLabel.text = self.searchResults[indexPath.row];
from the m file below. I am stumped. Any help would be greatly appreciated.

In your updateFilteredContentForAirlineName function you are searching from self.employees array which probably contains employee custom class object. For that reason your self.searchResults array also containing same class object.
But in your cellForRowAtIndexPath of SearchResultsTableViewController your are doing cell.textLabel.text = self.searchResults[indexPath.row]; that means you are adding employee object as string in cell.textLabel which causing your app to crash. Instead you can try this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"SearchResultCell" forIndexPath:indexPath];
employee *thisEmployee = self.searchResults[indexPath.row];
cell.textLabel.text = thisEmployee.fulNme;
return cell;

View flashes when popToRootViewController

I am having a problem with popToRootViewController. I have a root view A and a table view B. And when a row is selected in the table view I pass a string back to the root view and depending on the string. I change the title of buttons on A.
I have made a very simple version of this and put it on gitHub at this link: https://github.com/spennyf/didSelect_test. I am doing this because it is very hard to explain until you actually run this on your phone of the simulator. And see the flash. I don't know why it is happening or how to fix it. Any help would be greatly appreciated I will also post most of the code below, but if you could see the flash for yourself I think it would help explain the problem. Heres the code:

}

cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
//NSLog(#"%#", _objects);
cell.textLabel.text = [[_objects objectAtIndex:indexPath.row] objectForKey:#"title"];
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

myController.object = [[_objects objectAtIndex:indexPath.row] objectForKey:#"title"];
[self.navigationController popToRootViewControllerAnimated:YES];
}
#end
Again thanks for the help.
There is no problem with your code. It is intended behavior for UIButtons of type UIButtonTypeSystem to flash when its title is changed.
A simple workaround is to set the type of your buttons to UIButtonTypeCustom.
Edit:
You can change the type of the button in Interface Builder:

Get Object attributes in tableviewcontroller

I'm just going to be crazy. I want to display some attributes from an object in a TableViewController.
To resume :
I've got a first screen with a list of different Aircraft. Each Aircraft is different and get 2 attributes (a name and an identification number). When i click on an aircraft i want to display its informations in a new view controller (here a TableViewController).
The only thing i get is an empty string... I don't understand how to do this.

Thx for helping...
I don't exactly get your problem, but in your code you are:
//1. creating a new aircraft
Aircraft *aircraft = [[Aircraft alloc] init];
//2. this aircraft object is new and dose not have a name yet as you never assigned a name to it.
//3. this is why your log shows an empty string
NSLog(#"String is %#", aircraft.name);
Looks like you need to print the info:
NSLog(#"String is %#", _info);
But it will be helpful to help you if you could explain what you want to get better.

Passing data from dynamic tableview back to static tableview

Please help i have been struggling passing back the data. I have 2 tableViews. 1st tableview=static table=RootVC. 2nd tableview=dynamic table=FirstVC. in RootVC i have a cell with two labels, "repeatLabel" and "repeatDetail" with a disclosure indicator. When i click on the cell it display the next table which is FirstVC, FistVC is populated with weekdays. after selection of my choice, i want the selected days to be passed back into RootVC in "repeatDetail" and when i go back still be able to see previously selected data.
My RootVC looks like this:
#import "RepeatViewController.h"
#interface SettingsViewController : UITableViewController
#property (strong, nonatomic) IBOutlet UILabel *repeatDetail;
#property (strong, nonatomic) IBOutlet UILabel *repeatLabel;
#property (strong,nonatomic) NSString *getRepeatDetail;

When you work with static cells you have to bind the control you are using directly, there's no need.
So what I can suggest you is the following:
Bind your controls with some specific identifier, like labelFieldRow{rowid} example: labelFieldRow1.
So on prepare for segue, just check what's the selected row and pass the data you want to the destination controller.
Probably not the best, but it should work.
You have to pass data (selected by user before) from your RootVC to FirstVC. To do that in your RootVC add property to keep the selected data;
#property (nonatomic, strong) NSMutableArray *selectedDaysArray;
In prepareForSegue method you have to pass that array to let the table view know what needs to be selected:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
UIViewController *destinationController = segue.destinationViewController;
if( [destinationController isKindOfClass:[RepeatViewController class]] )
{
//You can reuse your selectedDays arrays
((RepeatViewController*)destinationController).selectedDays = self.selectedDaysArray;
[(RepeatViewController *)destinationController setReturnBlock:^(NSArray *retDaysArray) // <- make this change
{
// Save your changes
self.selectedDaysArray = [NSMutableArray arrayWithArray: retDaysArray]; // <- make this change
NSLog(#"DATA: %#", self.selectedDaysArray) //<- Add this debug line
}];
}
}
Remove this line from viewDidLoad you don't want to allocate it every time now you just pass it from rootVC
_selectedDays = [[NSMutableArray alloc] init];
And in cellForRowInIndexPath replace this line:
cell.textLabel.text = [completionBlock objectAtIndex:indexPath.row];
with this code:
NSString *day = completionBlock[indexPath.row];
cell.textLabel.text = day;
if ([self.selectedDays containsObject:day])
cell.accessoryType = UITableViewCellAccessoryCheckmark;
else
cell.accessoryType = UITableViewCellAccessoryNone;
And change didSelectRowAtIndexPath: to
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if (!self.selectedDays)
self.selectedDays = [[NSMutableArray alloc] init];
if (cell.accessoryType == UITableViewCellAccessoryCheckmark)
{
cell.accessoryType = UITableViewCellAccessoryNone;
//remove data from array
[self.selectedDays removeObject:[completionBlock objectAtIndex:indexPath.row]];
}
else
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
//add data to array
[self.selectedDays addObject:[completionBlock objectAtIndex:indexPath.row]];
}
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
Hope this help.

iOS reload UITableView using UISegmentedControl

Hi I'm trying to reload my table view based off of two different arrays. Which array should be loaded is determined by a segment control in the navigation bar. Currently it only will load the first array and nothing happens when the segment control is pressed. Below is my code any help as to why this isn't working is greatly appreciated. I've also checked that my IBAction segmenter is connected in the nib.
MessageViewController.h
#import <UIKit/UIKit.h>
#interface MessageViewController : UIViewController<UITableViewDelegate> {
IBOutlet UISegmentedControl *segmentControl;
IBOutlet UINavigationBar *navBar;
IBOutlet UITableView *tableView;
}
#property (retain, nonatomic) IBOutlet UISegmentedControl *segmentControl;
#property (retain, nonatomic) IBOutlet UITableView *tableView;
#property (nonatomic, retain) NSMutableArray *inbox;

Not sure why it wasn't working in the end all I did was delete the three classes and redo everything with the code above something must have just got borked along the way but it's working now and I'm a happy camper. Didn't need the delegate stuff either since that's all done in the nib so my original code worked fine.
set the delegate and datasource methods and take breakpoint to check the data . your code is right .
tableview.delegate=self;
tableView.datasource=self;
The only problem I see is that you're using a view controller with a table view in it, but you're not setting up the delegate for it in your viewDidLoad, and you're not implementing the delegate for your view controller.
#interface MessageViewController () <UITableViewDelegate, UITableViewDataSource>
#end
In viewDidLoad:
self.tableView.delegate = self;
self.tableView.dataSource = self;
Also make sure you have everything hooked up properly in IB, both your segmented control and your table view.
EDIT: I made my own test as per what you're trying to do, Here's my own implementation file
