It doesn't matter what I try I cant seem to even get past changing UITableView with the PFQueryTableViewController. I have added code, gone back through code, got rid of code and it all seems to throw the same error pretty much after changing from UITableView
i get
* Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason:'-[UITableViewController loadView] loaded the "2-view-3" nib but didn't get a UITableView.'
i'm just trying to populate a table from PARSE, basic stuff but i'm just trying to help my younger brother with my limited capabilities. Any help would be much appreciated
here's some code. i've linked to parse in my appdelegate, all that's fine. ive tested that.

i am very new to iOS how to get the selected cell values in one array and unselected cell value in the another array using by using checkmarks in objective c

for (int i=0; i<selectedRows.count; i++) {
[indexofselectedcell addObject:indexPath
customcell *cell = (customcell *)[_mytableview cellForRowAtIndexPath:indexPath];
NSString *test = cell.balance.text;
[valueofselectedcell addObject:test];

Pavithra I tried sample project for your question and output.If I get unselected and selected cells in separate array,it crashed as I could not check two array in cellForRowAtIndexPath.So that I save selected and unSelected values in one array.
I created simple understandable solution.I have set values in tableview as unselected as default.If you selected(when you click the cell) it shows UITableViewCellAccessoryCheckmark and other show UITableViewCellAccessoryNone.
It works perfectly.You can easily get.

I am trying to populate a UITableView that I put inside a UIViewController, underneath a UISegmentedControl, which is depicted in the picture:
Upon pressing any of the segments, I want the UITableView to be repopulated with a different set of data. Here is my relevant code:
#interface OTValuesViewController ()
#property (weak, nonatomic) IBOutlet UITableView *tableView;
#property (weak, nonatomic) IBOutlet UISegmentedControl *segmentControl;
#end
#implementation OTValuesViewController
- (IBAction)segmentValueChanged:(id)sender {

UINavigationItem *navItem = self.navigationItem;
UIBarButtonItem *addButton = navItem.rightBarButtonItem;
switch (segment.selectedSegmentIndex) {
case 0:
addButton.action = #selector(addNewVision:);
[self.tableView reloadData];
break;
case 1:
addButton.action = #selector(addNewPurpose:);
[self.tableView reloadData];
break;
case 2:

break;
}
}

}

My issue is: when I build and run the project, everything is fine -- the cells are populated in my default tab (vision). When I click a UISegmentedControl button, I get the error:
Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 1 beyond bounds [0 .. 0]'
If I remove:
self.tableView.dataSource = self;
self.tableView.delegate = self;
from my viewDidLoad, this error does not occur (though, the UITableView obviously doesn't get populated.) This leads me to believe that the error is derived from my populating the cells based on the UISegmentedController's selected segment, however, I do not know what is specifically causing it.
Any help would be greatly appreciated!
The problem is in your cellForRowAtIndexPath method. You try to use the current index path for all of your arrays, not just the applicable array. Try something like this:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UISegmentedControl *segment = self.segmentControl;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"OTValuesTableViewCell" forIndexPath:indexPath];
if (segment.selectedSegmentIndex==0) {
NSArray *visions = [[OTVisionStore sharedStore] allVisions];
OTVision *vision = [visions objectAtIndex:indexPath.row];
NSString *textLabel = [vision description];
cell.textLabel.text = textLabel;
}
else if (segment.selectedSegmentIndex==1) {
NSArray *purposes = [[OTPurposeStore sharedStore] allPurposes];
OTVision *purpose = [purposes objectAtIndex:indexPath.row];
NSString *textLabel = [purpose description];
cell.textLabel.text = textLabel;
}
else{
NSArray *plans = [[OTPlanStore sharedStore]allPlans];
OTVision *plan = [plans objectAtIndex:indexPath.row];
NSString *textLabel = [plan description];
cell.textLabel.text = textLabel;
}
return cell;
}
I'm new to the whole iOS developement, so not really good at it. I currently have a viewController with two tableviews. The first table is always visible and contains categories. The second table should only be visible when a cell from the first table is selected. The second table then contains subitems from the cell that was selected in the first tableview. Both tableviews are connected to their property in the .h file.
The viewcontroller itself is connected to a FoodAddViewController.h and FoodAddViewController.m file.
In the FoodAddViewController.h file, I have:
#import <UIKit/UIKit.h>
#class FoodAddViewController;
#interface FoodAddViewController : UIViewController<UITableViewDataSource, UITableViewDelegate>
#property (strong, nonatomic) IBOutlet UITableView *Categorien;
#property (strong, nonatomic) IBOutlet UITableView *Invulling;
- (IBAction)cancel:(id)sender;
#end
For the FoodAddViewController.m, I have:
#interface FoodAddViewController ()
{
NSArray *CategoryLabel;
NSMutableArray *elementen;
}
#end
#implementation FoodAddViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.Categorien.layer.transform = CATransform3DRotate(CATransform3DIdentity,-1.57079633,0,0,1);
self.Categorien.frame=CGRectMake(0,200, 700,234);
[self.Invulling setHidden:TRUE];
self.Invulling.layer.transform = CATransform3DRotate(CATransform3DIdentity,-1.57079633,0,0,1);
self.Invulling.frame=CGRectMake(0,200, 700,234);
self.Categorien.dataSource = self;
self.Categorien.delegate = self;
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"categorie" ofType:#"txt"];
NSString *content = [NSString stringWithContentsOfFile:filePath
encoding:NSMacOSRomanStringEncoding
error:NULL];
NSArray * categories = [content componentsSeparatedByString:#"\n"];
CategoryLabel = categories;
}
- (NSInteger) numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if(self.Categorien==tableView) {
return CategoryLabel.count;
}
if(self.Invulling==tableView) {
return elementen.count;
}
return 0;
}
- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(self.Categorien==tableView) {
static NSString *CellIdentifier = #"Cell";
CustomCell *Cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!Cell) {
Cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
Cell.layer.transform = CATransform3DRotate(CATransform3DIdentity,1.57079633,0,0,1);
Cell.frame=CGRectMake(0,0,234,150);
Cell.textLabel.text = [CategoryLabel objectAtIndex:indexPath.row];
return Cell;
}
if(self.Invulling==tableView) {
static NSString *CellIdentifier = #"DetailCell";
CustomCell *Cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!Cell) {
Cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
Cell.layer.transform = CATransform3DRotate(CATransform3DIdentity,1.57079633,0,0,1);
Cell.frame=CGRectMake(0,0,234,150);
Cell.textLabel.text = [elementen objectAtIndex:indexPath.row];
return Cell;
}
return NULL;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return 200;
}
- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
self.Invulling.dataSource = self;
self.Invulling.delegate = self;
elementen = [[NSMutableArray alloc]init];
if(self.Categorien==tableView) {
UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];
NSString *cellText = selectedCell.textLabel.text;
PFQuery *query = [PFQuery queryWithClassName:cellText];
[query selectKeys:#[#"Naam"]];
NSArray *result = [query findObjects];
for (PFObject *object in result) {
NSString *naam = object[#"Naam"];
if(![elementen containsObject:naam]) {
[elementen addObject:naam];
}
}
}
[self.Invulling setHidden:FALSE];
[self.Invulling reloadData];
}
end
Now, the problem is that the reloadData method does not work correctly. For example: if I press the first cell from the first tableview (Categorien), then nothing happens. But when I click another cell, the second tableview (Invulling) gets loaded with the results from the first cell.
you have to use didSelectRowAtIndexPath not didDeselectRowAtIndexPath method
Also look up some tutorial on debugging, you could have known that the method is not
being called if you have added breakpoints
You are using
- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:
Instead, use
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:
I am having an app in which I am showing some data in my tableview as shown in the ScreenShot1 below.
Screenshot1.
Now I am having an imageview On my each tableview cell.
If I select any of the cell from tableview, I want an image on that selected cell as shown in screenshot2 below.
Screenshot2.
Now If I select any other cell form tableview. I want to set my imageview's image only on those selected cells as shown in Screenshot3 below.
Below is the code I am doing.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
lblRecipe = [[UILabel alloc] initWithFrame:CGRectMake(50, 5, 600, 32)];
lblRecipe.backgroundColor = [UIColor clearColor];
lblRecipe.font = [UIFont systemFontOfSize:20.0f];
[cell.contentView addSubview:lblRecipe];
checkedimg=[[UIImageView alloc]initWithFrame:CGRectMake(40, 20, 500, 5)];
[cell.contentView addSubview:checkedimg];
lblRecipe.text = [array objectAtIndex:indexPath.row];
return cell;
}
On Tableview's didselect method, what should i keep to have this kind of a functionality?
I searched a lot and there are lots of questions for this but couldn't find one for this.
So Please help me on this.
Thanks in advance.
You may be better off just subclassing UITableViewCell, as this would let you change the way the cells draw, and add a property or something of the sort to indicate this state.
To create the subclass, create a new file in Xcode, and select UITableViewCell as its superclass.
Then, within that subclass, you could implement a method called setStrikeThrough: like this that you can call on the cell you dequeue from the table:
- (void) setStrikeThrough:(BOOL) striked {
if(striked) {
// create image view here and display, if it doesn't exist
} else {
// hide image view
}
}
Then, in the view controller that holds the table, you'd call this in viewDidLoad to register your subclass with the table view:
[_tableView registerClass:[YourAmazingTableCell class] forCellReuseIdentifier:#"AmazingCellSubclass"];
You would then alter your tableView:cellForRowAtIndexPath: to be something like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"AmazingCellSubclass";
YourAmazingTableCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[YourAmazingTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// here you would look up if this row should be selected
[cell setStrikeThrough:YES];
// Set up the remainder of the cell, again based on the row
cell.textLabel.text = #"chilli";
return cell;
}
Try this,
Add a NSMutableArray checkedCellArray, as property and alloc init.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
UILabel *labelRecipe = [[UILabel alloc] initWithFrame:CGRectMake(50, 5, 600, 32)];
labelRecipe.backgroundColor = [UIColor clearColor];
labelRecipe.font = [UIFont systemFontOfSize:20.0f];
labelRecipe.tag = kRecipeTag;//a tag to label
[cell.contentView addSubview:labelRecipe];
UIImageView *checkedimg = [[UIImageView alloc]initWithFrame:CGRectMake(40, 20, 500, 5)];
[checkedimg setImage:[UIImage imageNamed:#"checked.png"];
checkedimg.tag = kCheckedImageTag;//a tag to imageView
[cell.contentView addSubview:checkedimg];
checkedimg.hidden = YES;
}
UILabel *labelRecipe = (UILabel *)[cell.contentView viewWithTag:kRecipeTag];
UIImageView *checkedimg = (UIImageView *)[cell.contentView viewWithTag:kCheckedImageTag];
if ([self.checkedCellArray containsObject:indexPath]) {
checkedimg.hidden = NO;
} else {
checkedimg.hidden = YES;
}
labelRecipe.text = [array objectAtIndex:indexPath.row];
return cell;
}
and in didSelectRowAtIndexPath:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (![self.checkedCellArray containsObject:indexPath]) {
[self.checkedCellArray addObject:indexPath];
}
NSArray* rowsToReload = [NSArray arrayWithObjects:indexPath, nil];
[UITableView reloadRowsAtIndexPaths:rowsToReload withRowAnimation:UITableViewRowAnimationNone];
}
Oky hear you can do like this
just subclass the tableview cell
in CustomCell.h file
#import <UIKit/UIKit.h>
#interface CustomCell : UITableViewCell
#property (nonatomic,retain)UIImageView *dashImageView; //add a property of image view
#end
in CustomCell.m file
#import "CustomCell.h"
#implementation CustomCell
{
BOOL isCellSelected; //add this to check
}
#synthesize dashImageView = _dashImageView; //synthesize it
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
isCellSelected = NO;//initially set it no
_dashImageView = [[UIImageView alloc]initWithFrame:CGRectMake(self.bounds.origin.x + 15, self.bounds.origin.y + 10, self.bounds.size.width, 15.0f)];
_dashImageView.backgroundColor = [UIColor redColor];
_dashImageView.tag = 12345;
_dashImageView.hidden = YES;
[self.contentView addSubview:_dashImageView];
}
return self;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
if(selected)
{
UIImageView *dashImageVIew = (UIImageView *)[self viewWithTag:12345];
if(dashImageVIew)
{
if(!isCellSelected)
{
dashImageVIew.hidden = NO;
isCellSelected = YES;
}
else
{
dashImageVIew.hidden = YES;
isCellSelected = NO;
}
}
}
}
EDIT:2 *For selecting both section and row for the table view*
there is no change in the custom cell only change in the controller so that u hav to reflect what changes that u made to tableview cell i.e weather u select or deselect
since u want select section along with the selected row.(your requirement) there are various way to do that, but i go by using some model object which contains index section and row.
for that u need to create a subclass of NSObject and name it as MySelectedIndex then in
in MySelectedIndex.h file
#import <Foundation/Foundation.h>
#interface MySelectedIndex : NSObject<NSCoding>//to store and retrieve data like user defaults, for non-property list objects, confirms to NSCoding protocol
#property (nonatomic,retain) NSNumber *selectedRow;
#property (nonatomic,retain) NSNumber *selectedSection;
- (id)initWithSelectedRow:(NSNumber *)selRow andSelectedIndex:(NSNumber *)selSection;
#end
in MySelectedIndex.m file
#import "MySelectedIndex.h"
#implementation MySelectedIndex
#synthesize selectedSection = _selectedSection;
#synthesize selectedRow = _selectedRow;
- (id)initWithSelectedRow:(NSNumber *)selRow andSelectedIndex:(NSNumber *)selSection
{
self = [super init];
if(self)
{
_selectedRow = selRow;
_selectedSection = selSection;
}
return self;
}
- (void)encodeWithCoder:(NSCoder *)aCoder
{
[aCoder encodeObject:_selectedRow forKey:#"ROW"];
[aCoder encodeObject:_selectedSection forKey:#"SECTION"];
}
-(id)initWithCoder:(NSCoder *)aDecoder
{
self = [super init];
if(self)
{
_selectedRow = [aDecoder decodeObjectForKey:#"ROW"];
_selectedSection = [aDecoder decodeObjectForKey:#"SECTION"];
}
return self;
}
#end
now get back to controller where u are using the table
in .m file
import it #import "CustomCell.h"
and in the method
in viewController.m
#interface SampleViewController ()<UITableViewDataSource,UITableViewDelegate>
{
NSMutableArray *indexes;//to store in defaults
NSMutableArray *indexesRed;//to red from the defaults
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
//...other stuff's
indexes = [[NSMutableArray alloc]init];//initilise your arrays
indexesRed = [[NSMutableArray alloc]init];
//after initilizing your array
NSData *data = [[NSUserDefaults standardUserDefaults] objectForKey:#"SELECTED_CELLL"];
if(data != nil)
{
indexes = [NSKeyedUnarchiver unarchiveObjectWithData:data];
[indexes retain];//you hav to retain the objects other wise u will get crash, make sure u will release it by proper memory mabagement (if u are not using ARC)
}
}
as u said u are using buttons to pop this viewcontroller so already u know where to place so put this in all the action methods(just replace where u are saving to user defaults )
and also read the comments that i put in the code
//put all these codes where u poping this viewcontroller
NSData *data = [NSKeyedArchiver archivedDataWithRootObject:indexes];
[[NSUserDefaults standardUserDefaults] setObject:data forKey:#"SELECTED_CELLL"];
[[NSUserDefaults standardUserDefaults] synchronize];
[self.navigationController popViewControllerAnimated:YES];
replace the cellForRowAtIndexPath by following code (i added in the below method)
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:( NSIndexPath *)indexPath
{
CustomTabedCell *Cell = [tableView dequeueReusableCellWithIdentifier:#"CELL"];
if(Cell == nil)
{
Cell = [[CustomTabedCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"CELL"];
}
Cell.textLabel.text = #"Apple";
NSNumber *rowNum = [NSNumber numberWithInt:indexPath.row];
NSNumber *secNum = [NSNumber numberWithInt:indexPath.section];
__block BOOL isImageHidden = YES;
[indexes enumerateObjectsUsingBlock:^(MySelectedIndex *obj, NSUInteger idx, BOOL *stop)
{
if(obj.selectedRow == rowNum && obj.selectedSection == secNum)
{
isImageHidden = NO;
}

thats it simple .. :)
hope this helps u .. :)

I have implemented the search functionality as below. I am able to retrieve the rows based on search string but they are empty, when i click on the empty search result cell am able to navigate correctly for each search result.I am using story board configured cells to display the table. I mean am using tags in order to populate the data and the images.

-(void)searchBarSearchButtonClicked:(UISearchBar *)searchBar

[self.searchBar resignFirstResponder];
}
Edit :
after changing the code to self.tableview :
Instead of this :
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
use this :
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
Search results displayed in a separate table view. So if you use tableView without self you may be referring search results table view.
