UITableViewCell Subtitle not showing up - ios

I have my UITableView displaying JSON info being returned from a cloud code function. For some reason, it correctly displays the titles of the items being returned, but I can't get it to display the price as a subtitle of each cell. Setting the style as UITableViewCellStyleSubtitle doesn't seem to work, and gives me a warning stating Implicit conversion from enumeration type 'enum UITableviewCellStyle' to different enumeration type.

The cell you have registered is a default styled UITableViewCell, it does not have a subTitle. You can't change the style of the cell once it's created.
You basically have two options:
create a simple UITableViewCell subclass that uses UITableViewCellStyleSubtitle (or any other style of your choice)
#interface MyTableViewCell : UITableViewCell
#end
#implementation MyTableViewCell
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
// overwrite style
self = [super initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:reuseIdentifier];
return self;
}
#end
...
[self.matchCenter registerClass:[MyTableViewCell class] forCellReuseIdentifier:#"Cell"];
Or return to the old style dequeue technique where you create a cell if none could be dequeued
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
// if no cell could be dequeued create a new one
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
/* configure */
}
If you do this, you have to remove the registerClass:forCellReuseIdentifier: call.
I would go with option one, because most likely pretty soon you will figure out that the built in cells are very limited and you want to add your own views (e.g. labels, image views). And if you use a subclass you can use properties to access those views, and don't have to use hacks like tags to access them.

In Table View subtitle is not present otherwise you customize your cell
use detail text label
cell.detailTextLabel.text = [array objectForKey:#"Value"];

Populate UITableView from NSMutableArray

Having an issue where the array values do not display in my tableview cells, but can be printed out correctly with NSLog. Thanks in advance for your help!

cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}

NSLog(#"%#", _namesArray[indexPath.row]);
cell.image.image = [self.imagesArray objectAtIndex:indexPath.row];
[cell setAccessoryType: UITableViewCellAccessoryDisclosureIndicator];
return cell;
}
When you make the cell in a xib file, you should register the nib in viewDidLoad. Since you didn't do that, the dequeue method will return nil, and you're just creating a default cell (in the if (cell == nil) clause) instead of your custom cell. The default cell doesn't have a nameLabel or image property, so the lines to set the values of those outlets won't do anything.
[self.tableView registerNib:[UINib nibWithNibName:#"Your nib name here" bundle:nil] forCellReuseIdentifier:#"TableViewCell];
In your TableViewController class, you need to include
self.tableView.delegate = self;
self.tableView.datasource = self;
in your viewDidLoad method. Or you can do this in interface builder by right click dragging the table view in your tableview controller to file's owner and setting delegate, then repeat for datasource

PFQueryTableViewController with custom cells crash while launching

I do not understand to this but always when I try to launch my app, I get error.
Can someone help me? I think it will be maybe something in TableeViewController.m. But i am not sure.

It looks like you have subclassed the PFTableViewCell and created the properties "cellTitle" and "cellDescription" but you haven't initialized and added them them in TableCell.
There seems to be no reason to subclass the PFTableViewCell if you are not making any changes to it. You can actually just use the normal UITableViewCell.
So, delete "TableCell" and create the cells by using a UITableViewCell:
static NSString *simpleTableIdentifier = #"ColorsCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:simpleTableIdentifier];
}
Then you can access the properties "textLabel" and "detailTextLabel" by doing this:
cell.textLabel.text = [object objectForKey:#"cellTitle"];
cell.detailTextLabel.text = [object objectForKey:#"cellDescript"];

Good luck!

Adding a UITableView as a Subview

I am trying to create a view that has a UITableView as only part of that view. I believe this is the correct pattern when creating from code (not interface builder) but please feel free to add suggestions if my approach is wrong as well.
The exception I am getting is:
[KBSMoreViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance
I have a class header as below (I am implementing the constructor in the implementation):
#import <UIKit/UIKit.h>
#interface KBSMoreTableView : UITableView
- (id)initWithFrame:(CGRect)frame style:(UITableViewStyle)style;
#end
I then have a ViewController class header as:
#interface KBSMoreViewController : UIViewController <UITableViewDataSource, UITableViewDelegate>
#end
The ViewController, which is part of a tab bar and works fine (outside of the tableview I am trying to add) implementation is written as:
#import "../Models/KBSMoreTableView.h"
#interface KBSMoreViewController ()
#property (strong, nonatomic) KBSMoreTableView* tableView;
#property (strong, nonatomic) NSString* cellIdentifier;
#property (copy, nonatomic) NSArray *source;
#end
#implementation KBSMoreViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.tabBarItem = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemMore tag:0];
self.source = [[NSArray alloc] initWithObjects:#"Test1", #"Test2", nil];
self.cellIdentifier = #"MoreCellId";
}
return self;
}
- (NSInteger)numberOfRowsInSection:(NSInteger)section
{
return self.source.count;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:self.cellIdentifier];
if (cell == nil)
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:self.cellIdentifier];
cell.textLabel.text = self.source[indexPath.row];
return cell;
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.tableView = [[KBSMoreTableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain];
self.tableView.dataSource = self;
self.tableView.delegate = self;
[self.view addSubview:self.tableView];
}
The error is very clear. You don't implement the tableView:numberOfRowsInSection: table view data source method. Instead, you have created a method named numberOfRowsInSection:.
Change this:
- (NSInteger)numberOfRowsInSection:(NSInteger)section
to:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

cellForRowAtIndexPath doesn't work

On my xcode project I have a view with a tableview. I also have a "special" string that contains the objects to populate the array that populates the tableview.
Example:
NSString *myValues=[[NSString alloc]init];
myValues = #"aaa$bbb$ccc?111$222$333?";
as you can see the characters $ and ? separate the objects.
When I call the view I populate the array by the string but the tableview doesn't work. Here some code:

On nib file the tableview has the connection with the delegate and datasource, as the IBoutlet is connected with it.
Thanks for your support.
EDIT: [arrayEquipaggio count] return 0.
By the looks of your question your problem is that the method cellForRowAtIndexPath is not being called and as you said the [arrayEquipaggio count] return 0.
Since you are using that array at the method numberOfRowsInSection with a return value of 0 is normal that your table is not calling the method cellForRowAtIndexPath. Since you are telling to your table that there are no rows.
If you want your table to be populated then check that your array return a value greater than 0.
In a nutshell It has no data to populate your table, that why it doesnt work.
Check that in your viewDidAppear:(BOOL)animated that your are pulling anything to stringaDati.
NSLog(#"info: %#",stringaDati);

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.

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
