Grabbing the value of specific textlabel and making json in didSelectRowAtIndexPath - ios

Following is my cellForRowAtIndexPath method in MyOrdersController.m file...
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = nil;
cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:#""];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:nil];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
self.shipmentReferenceNumberTextLabel = [[UILabel alloc]init];
self.shipmentReferenceNumberTextLabel.text = amountArray[indexPath.row];
self.shipmentReferenceNumberTextLabel.font = [UIFont fontWithName:#"HelveticaNeue" size:10];
tableView.tableFooterView = [UIView new];
cell.layer.borderWidth = 1.0;
cell.layer.cornerRadius = 10;
cell.layer.borderColor = [UIColor blackColor].CGColor;
[cell.contentView addSubview:self.productAmountLabel];
[cell.contentView addSubview:self.productAmountTextLabel];
return cell;
}
I have got a textlabel shipmentReferenceNumberTextLabel in it. I have to grab the value of shipmentReferenceNumber when a user clicks on a particular cell and I have to make json request with it in a file called APIRequest.m. Im trying grab its value as follows,
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
{
tabBar = [self.storyboard instantiateViewControllerWithIdentifier:#"TabBarController"];
[self.navigationController pushViewController:tabBar animated:YES];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
MyOrdersController *detailVC = [[MyOrdersController alloc]init];
NSLog(#"%#", detailVC.shipmentReferenceNumberTextLabel.text);
}
The problem is that, its printing null while im trying to grab its value. How can I sort out this issue.

You can get value of Lable from an array.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
{
NSLog(#"%#",amountArray[indexPath.row]);
}
You will get selected row's label value.

In UItableview, when I scroll table values are miss placing(values selecting from picker)

Here I am trying to do dynamic UITableViewCell with UIPickerView.
Step 1:
In Custom cell, I took 1 label and 1 UITextField.
Step 2:
used downpickerview library for data displaying and data fetching.
Step 3:
using below code I can able to select data, but after that, if I scroll UITableView data will be miss placing.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = #"Cell";
customCell *cell1=[tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell1 == nil)
{
cell1 = [[customCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier];
}
cell1.productTitleLabel.text =[arrProductTitle objectAtIndex:indexPath.row];
self.downPicker = [[DownPicker alloc] initWithTextField:cell1.productvalueTextfield withData:arrProductVal];
[self.downPicker addTarget:self action:#selector(measurementSelected:) forControlEvents:UIControlEventValueChanged];
[cell1.contentView addSubview:self.downPicker];
return cell1;
}
Please help me on this.

[super viewDidLoad];
self.navigationItem.title = #"DETAILS";
_dict = [[NSMutableDictionary alloc]init];

UITableViewCell values are misplacing because you haven't set the data for other cells, You need to store the values in an array and just update the values from there and it will work. :)
Something is not right with your code:
cell1.productTitleLabel.text =[arrProductTitle objectAtIndex:indexPath.row];
self.downPicker = [[DownPicker alloc] initWithTextField:cell1.productvalueTextfield withData:arrProductVal];
[self.downPicker addTarget:self action:#selector(measurementSelected:) forControlEvents:UIControlEventValueChanged];
[cell1.contentView addSubview:self.downPicker];
Bear in mind that in iOS, a tableView will reuse its cells. So when you scroll your UITableView, it will reuse the old cells which were created before, and
[cell1.contentView addSubview:self.downPicker]; Will be executed everytime a cell is reused, as a result, you will end up having many downPicker objects in one cell.

How can we select tableList row bydefault

Hi i am very new for ios and in my app i have created
one UItablaList ok fine
here by default my tableList row one textcolor
i have assigned like "RED"
and when i click on another rows that first row color must be "WHITE" and selected row color must be "RED" and if i click dy default selected first row then that color must be "RED please help me some one ,How can we implement logic for this
my code:-
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *simpleTableIdentifier = #"MyCell";
MyCellTableViewCell *cell = (MyCellTableViewCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"MyCellTableViewCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
UILabel *lineLbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 55, RightMenuTbl.frame.size.width, 1)];
lineLbl.backgroundColor = [UIColor lightGrayColor];
[cell.contentView addSubview:lineLbl];
//remove background for table:-
if (indexPath.row == 0) {
lineLbl.textColor = [UIColor redColor];
}
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
}
Take int as selectedRow in .h file and in didselectrow
selectedRow = indexPath.row;
[yourtableview reloadData];
and in cellforrow
if (selectedRow== indexPath.row) {
lineLbl.textColor = set color you want for selected
}else
lineLbl.textColor = set color you want for not
selected
try this code:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSIndexPath * cellIndexPath = indexPath;
SubCategoryCell * cell = (SubCategoryCell*)[tableView cellForRowAtIndexPath:cellIndexPath];
cell.nameLbl.textColor = [UIColor redColor];
}
(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
SubCategoryCell * cell = (SubCategoryCell*)[tableView cellForRowAtIndexPath:indexPath];
cell.nameLbl.textColor = [UIColor whiteColor];
}
Try the below code:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
SubCategoryCell * cell = (SubCategoryCell*)[tableView cellForRowAtIndexPath:indexPath];
cell.nameLbl.textColor = [UIColor redColor];
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
SubCategoryCell * cell = (SubCategoryCell*)[tableView cellForRowAtIndexPath:indexPath];
cell.nameLbl.textColor = [UIColor whiteColor];
}

UITableView unresponsive to gestures and not populating cells with data

I created a UITableView programmatically and set all of its attributes, but the data from my NSMutableArray will not populate the cells and the cells do nothing when tapped. Any insight appreciated, thanks!
Clayton
- (void)viewDidLoad {
[super viewDidLoad];
[self.view setBackgroundColor:[UIColor whiteColor]];
list = [[UITableView alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height * .3333, self.view.bounds.size.width, self.view.bounds.size.height * .6667) style:UITableViewStylePlain];
list.delegate = self;
list.dataSource = self;
list.backgroundColor = [UIColor magentaColor];
list.scrollEnabled = YES;
list.userInteractionEnabled = YES;
list.multipleTouchEnabled = YES;
list.hidden = NO;
[self.view addSubview:list];
[self.view bringSubviewToFront:list];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [favorites count];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *Cell = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:Cell];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:Cell];
}
cell.textLabel.text = [[global sharedInstance].favorites objectAtIndex:indexPath.row];
cell.textLabel.textColor = [UIColor blackColor];
cell.userInteractionEnabled = YES;
cell.hidden = NO;
cell.multipleTouchEnabled = YES;
[self.view bringSubviewToFront:cell];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"selected %ld row", (long)indexPath.row);
}
Got it thanks, the problem was with the data transferring from my singleton array of favorites to my local array (which was previously empty). Much obliged :)
At the end of viewDidLoad method, just add this:
[list reloadData];

Accessory type for Cross Sign in iOS

I have a table view and 2 custom cells inside it. I want to use a (X) symbol i.e. the cross symbol and the tick symbol. I know for tick we have UITableViewCellAccessoryCheckmark but what to do for the (X) symbol. Can we have any custom accessory for this or else how to achieve this?
My code:
#pragma mark - Table View Methods
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 2;
}
- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
optionsLabelArray = [[NSArray alloc] initWithObjects:#"Yes", #"No", nil];
static NSString *CellIdentifier = #"CheckerCell";
CustomCell *cell =[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell.optionLabel.text = [optionsLabelArray objectAtIndex:indexPath.row];
cell.optionLabelSubtitle.text = [optionsLabelSubtitleArray objectAtIndex:indexPath.row];
if(indexPath.row == 0)
{
cell.textLabel.textColor = [UIColor colorWithRed:78/255.0 green:157/255.0 blue:19/255.0 alpha:1.0];
}
else if(indexPath.row == 1)
{
cell.textLabel.textColor = [UIColor colorWithRed:167/255.0 green:19/255.0 blue:43/255.0 alpha:1.0];
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (tableView ==_optionsTableView1) {
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
previousSelectedCell1.accessoryType = UITableViewCellAccessoryNone;
cell.accessoryType=UITableViewCellAccessoryCheckmark;
previousSelectedCell1 = cell;
NSLog(#"Row : %ld", (long)indexPath.row);
if(indexPath.row == 0)
{
self.weatherSafeToPlay = YES;
}
else
{
// MatchDayDataController *sharedController = [MatchDayDataController sharedDataController];
// sharedController.actions = [sharedController.actions stringByAppendingString:#"Check Weather. "];
//[sharedController.actions appendString:#"Check Weather. "];
self.weatherSafeToPlay = NO;
}
NSLog(#"Is Weather safe: %hhd", self.weatherSafeToPlay);
}
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
not heard of any accessory type for cross but in such cases, i simply use unicode characters.
It's lighter than using an image and is a simple matter of just changing the text.
#"\u2713" for ✓
#"\u2717" for ✗
You can:
Create a custom UITableViewCell having a 32by32 (or any dimension) UILabel (on the right/left/middle/wherever)
in -didSelectRowAtIndexPath, you can change the text of this UILabel
#"\u2713" for checkmark or #"\u2717" for crossmark
A simple example (on the default UITableViewCell's default textLabel, just for the idea):
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if([cell.textLabel.text isEqualToString:#"\u2713"]) {
cell.textLabel.text = #"\u2717";
}
else {
cell.textLabel.text = #"\u2713";
}
}
OR... when not using a custom cell, something like:
-(UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil) {
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
}
//set your text to cell.textLabel.text
//create your own UILabel
UILabel *lblAcc = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 32, 32)];
[lblAcc setTag:100];
[lblAcc setText:#"?"];
[lblAcc setBackgroundColor:[UIColor redColor]];
[lblAcc setTextAlignment:NSTextAlignmentCenter];
//set as custom AccessoryView on cell
[cell setAccessoryView:lblAcc];
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
NSString *strAccessory = [(UILabel *) [cell viewWithTag:100] text];
//the -isEqualToString is a bit heavier than checking a simple bool or int value
//so since you should be remembering the selected cells anyways, you can change
//the if-logic to compare with a bool rather than the string comparison.
//but for now, we'll do:
if([strAccessory isEqualToString:#"\u2713"]) {
[(UILabel *) [cell viewWithTag:100] setText:#"\u2717"];
}
else {
[(UILabel *) [cell viewWithTag:100] setText:#"\u2713"];
}
}
for more unicode characters... this link:
http://en.wikibooks.org/wiki/Unicode/List_of_useful_symbols
You can assign your own image to accessoryView of table cell. Create an image of (X) symbol and use that image as accessoryView.
cell.accessoryView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:#"Your X Image"]];

Custom Check mark for selected Row

I am using a Custom image for checkmark - 'iphone-checkMark#2x.png' in a `UITableViewCell, but it's displaying everywhere in the cell. Can anyone suggest how to make it display only for the single selected cell?
Here is my code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10,10, 300, 30)];
[cell.contentView addSubview:label];
label.text = [tableArr objectAtIndex:indexPath.row];
label.font = [UIFont fontWithName:#"Whitney-Light" size:20.0];
label.tag = 1;
UIImageView *checkmark = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"iphone-checkMark#2x.png"]];
cell.accessoryView = checkmark;
return cell;
}
Less code is better:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell =[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
}
cell.textLabel.text = [tableArr objectAtIndex:indexPath.row];
cell.textLabel = [UIFont fontWithName:#"Whitney-Light" size:20.0];
return cell;
}
UPDATE:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
lastIndexPath = indexPath;
[tableView reloadData];
}
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
if ([lastIndexPath isEqual:indexPath]) {
cell.accessoryView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"iphone-checkMark.png"]];
} else {
cell.accessoryView = nil;
}
}
UPDATE 2:
Write
//dont forget check for nil
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setValue:lastIndexPath forKey:#"lastIndexPath"];
[defaults synchronize];
Read
NSIndexPath *lastPath = [defaults valueForKey:#"lastIndexPath"];
One way to achieve what you are trying to do is to use a button and set the background image as your checkbox. This button will be your accessoryView. Monitor the touch event on the button and display the boolean accordingly. The sample project in the following link will provide all the code you need to implement this. https://developer.apple.com/library/ios/#samplecode/Accessory/Introduction/Intro.html
