I want to add custom UIButton to UITableViewCell - ios

In customCell I create some UIButtons and [self addSubview:button];
In UITableView [button addTarget:action:forControlEvents:],When I click button in cell indexPath.row = 0,the indexPath.row = 11 was clicked;
How to get clicked the button and other buttons are not affected?

nameLabel.textColor = [UIColor blackColor];
self.nameLabel = nameLabel;
[self addSubview:nameLabel];
[nameLabel release];
CGFloat rightX = IsIOS7?180:160;

25)];
fileSizeLabel.backgroundColor = [UIColor clearColor];
fileSizeLabel.font = [UIFont systemFontOfSize:14];

self.fileSizeLabel = fileSizeLabel;
[self addSubview:fileSizeLabel];
[fileSizeLabel release];
//This is customButton
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(rightX, 10, 50, 25);
button.backgroundColor = [UIColor grayColor];
self.WIFIButton = button;
[self addSubview:button];
}

Jumping the gun a little on the code, but please consider the following. Add a method that can find the cell where a view appears without using tags.
- (NSIndexPath *)indexPathOfSubview:(UIView *)view {
while (view && ![view isKindOfClass:[UITableViewCell self]]) {
view = view.superview;
}
UITableViewCell *cell = (UITableViewCell *)view;
return [self.tableView indexPathForCell:cell];
}
This assumes you have an outlet called tableView pointing to a table (and it assumes that the parameter is a subview of one of the table's cells). Now, on whatever method runs when a button is pressed:
- (IBAction)myButtonPressed:(id)sender {
NSIndexPath *indexPath = [self indexPathOfSubview:sender];
NSLog(#"button pressed in section %d, at row %d", indexPath.section, indexPath.row);
// ta-da!
}

change static to dynamic cell
static NSString *identifier = #"cell";
to
NSString *identifier = [NSString stringWithFormat:#"cell%d",indexPath.row];
may be its working

Button Getting Populating Some Other Cell in UITableViewCell using Objective C?

I have created UITableview Programmatically and Populated array values dynamically. Here My Problem is, I created a UIButton Programmatically for zeroth row, It created well but When I am Scrolling the tableview button is Populating some other cells also. I don't Know how to solve that issue in my tableview. I want a UIButton on Only Zeroth index of the cell. I have tried the below code..
- (IBAction)MoreBttn:(id)sender {
NSUserDefaults *userDefaults1 = [NSUserDefaults standardUserDefaults];
[userDefaults1 setObject:amenties forKey:#"FACILITIES"];
CGRect screenRect = [[UIScreen mainScreen] bounds];
amentiestableview=[[UITableView alloc]initWithFrame:screenRect style:UITableViewStylePlain];
amentiestableview.delegate=self;
amentiestableview.dataSource=self;
UIEdgeInsets insets = UIEdgeInsetsMake(20,10,20,10);
CGRect tableframe=amentiestableview.frame;
amentiestableview.frame=UIEdgeInsetsInsetRect(tableframe,insets);
[[UIApplication sharedApplication].keyWindow addSubview:amentiestableview];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [amenties count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"facilities";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
if(indexPath.row == 0) {
UIButton *b = [UIButton buttonWithType:UIButtonTypeCustom];
float X_Co = self.tableView.frame.size.width - 60;
[b setFrame:CGRectMake(X_Co, 0.0, 60, 45)];
[b setTitle:#"button" forState:UIControlStateNormal];
[b addTarget:self
action:#selector(hidetableview:)
forControlEvents:UIControlEventTouchUpInside];
[b setImage:[UIImage imageNamed:#"clearpink.png"] forState:UIControlStateNormal];
[cell addSubview:b];
}
else{
}
cell.textLabel.text=[amenties objectAtIndex:indexPath.row];
return cell;
}
-(void)hidetableview:(UIButton*)sender
{
amentiestableview.hidden=YES;
}
The cell is being re-used, so the button appear on other cells. Try to update cellForRow method as follows:
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
UIButton *b = [UIButton buttonWithType:UIButtonTypeCustom];
float X_Co = self.tableView.frame.size.width - 60;
[b setFrame:CGRectMake(X_Co, 0.0, 60, 45)];
[b setTitle:#"button" forState:UIControlStateNormal];
[b addTarget:self
action:#selector(hidetableview:)
forControlEvents:UIControlEventTouchUpInside];
[b setImage:[UIImage imageNamed:#"clearpink.png"] forState:UIControlStateNormal];
[cell addSubview:b];
}
if(indexPath.row == 0) {
b.hidden = false
}
else{
b.hidden = true
}
We are recycling the cells by using the method dequeueReusableCellWithIdentifier. And you should recycle cells because the allocation of views need a lot of resources
Please try the below code
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
if(indexPath.row == 0) {
UIButton *b = [UIButton buttonWithType:UIButtonTypeCustom];
float X_Co = self.tableView.frame.size.width - 60;
[b setFrame:CGRectMake(X_Co, 0.0, 60, 45)];
[b setTitle:#"button" forState:UIControlStateNormal];
[b addTarget:self
action:#selector(hidetableview:)
forControlEvents:UIControlEventTouchUpInside];
[b setImage:[UIImage imageNamed:#"clearpink.png"] forState:UIControlStateNormal];
b.tag = 1010
[cell addSubview:b];
}
else{
cell.contentView.viewWithTag(1010).removeFromSuperview()
}

changing UIButton image background in Table view cell for particular row base on som condition

I have a custom table view in my app which has button in each row.

it is successfully executing if statements.
Just the button's background image is not changing.

In your implementation every time you are creating new cell, after getting cell from "dequeueReusableCellWithIdentifier" you have to check for cell if it nil than only create new cell using "alloc-init".
The better implementation of the particular senireo is to take a custom UITableViewCell.
The following stategie you should follow.
In the custom cell create the outlet for label 1, 2 and 3, than set the test in cellForRowatIndexPath.
Create a property of NSMutableArray in the custom cell class.
After getting the cell from "dequeueReusableCellWithIdentifier" check if cell is nil than only create the buttons and add all the buttons in the NSMutableArray created in step 2.
take the buttons from the NSMutableArray and that apply the condition for setting the images.
Please see the below code:
- (UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if(tableView == tablePatchFilter)
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell"];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"cell"];
}
cell.textLabel.text=[filterPatchName objectAtIndex:indexPath.row];
return cell;
} else {
CustomTableViewCell *cell = (CustomTableViewCell*)[tableView dequeueReusableCellWithIdentifier:#"cell"];
if (!cell) {
cell = [[CustomTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"cell"];
int selectedSegment = mainSegment.selectedSegmentIndex;
if(selectedSegment == 0) {
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.tag=indexPath.row;
[btn addTarget:self action:#selector(takeSignature:) forControlEvents:UIControlEventTouchUpInside];
[cell.buttonArray addObject:btn];
}
}
cell.accessoryType=UITableViewCellAccessoryDisclosureIndicator;
cell.textLabel.text=[displayItems objectAtIndex:indexPath.row];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.label1.text = [displayItemsType objectAtIndex:indexPath.row];
cell.label2.text = [displayItemPatch objectAtIndex:indexPath.row];
cell.label3.text = [displayItemclass objectAtIndex:indexPath.row];
for (UIButton *btn in cell.buttonArray) {
NSMutableString *pathhh= [NSMutableString stringWithFormat:#"%#",[displayFlag objectAtIndex:i]];
if([pathhh isEqualToString:#"1"]) {
btn.frame = CGRectMake(850,1, 50, 50);
[btn setBackgroundImage:[UIImage imageNamed:#"signature.png"] forState:UIControlStateNormal];
} else {
btn.frame = CGRectMake(850,1, 50, 50);
[btn setBackgroundImage:[UIImage imageNamed:#"add.png"] forState:UIControlStateNormal];
}
}
return cell;
}
}

How to change button background color which is added on table view cell when we tapped on it?

I have added one custom button on tableview cell and everything is ok.
But here my main requirement is when I click that button for the "first time" which is added on table view cell, then the button background color needs to change(to red) and when I click the second time the button, the previous color needs to be displayed(back to white)
My code:
#import "ViewController2.h"
#interface ViewController2 ()
{
NSArray * Mainarray;
UITableView * MaintableView;
UIImageView * accessoryView;
UIButton *button;
BOOL tapped;
}
#end
#implementation ViewController2
- (void)viewDidLoad
{
[super viewDidLoad];
tapped = NO;
Mainarray = [[NSArray alloc]initWithObjects:#"Ram",#"Rama",#"Rakesh",#"Ranjith", nil];
self.view.backgroundColor = [UIColor darkGrayColor];
MaintableView = [[UITableView alloc]init];
MaintableView.translatesAutoresizingMaskIntoConstraints = NO;
MaintableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
MaintableView.dataSource=self;
MaintableView.delegate=self;
MaintableView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
[MaintableView registerClass:[UITableViewCell class] forCellReuseIdentifier:#"Cell"];
[self.view addSubview:MaintableView];
NSDictionary * views = NSDictionaryOfVariableBindings(MaintableView);
NSArray * horizentalConstraint = [NSLayoutConstraint constraintsWithVisualFormat:#"H:|-0-[MaintableView]-0-|" options:0 metrics:nil views:views];
NSArray * verticalConstraint = [NSLayoutConstraint constraintsWithVisualFormat:#"V:|-0-[MaintableView]-0-|"options:0 metrics:nil views:views];
[self.view addConstraints:horizentalConstraint];
[self.view addConstraints:verticalConstraint];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return Mainarray.count;
}

return 50;
}

if (Cell == nil)
{

}
Cell.textLabel.text = [Mainarray objectAtIndex:indexPath.row];
button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
button.tag=indexPath.row;
[button addTarget:self
action:#selector(aMethod:) forControlEvents:UIControlEventTouchDown];
[button setTitle:#"" forState:UIControlStateNormal];
button.frame = CGRectMake(Cell.frame.size.width - 50, 10, 30, 30);
button.layer.cornerRadius = 60/2.0f;

}
}
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
if ([cell respondsToSelector:#selector(setSeparatorInset:)]) {
[cell setSeparatorInset:UIEdgeInsetsZero];
}
if ([cell respondsToSelector:#selector(setPreservesSuperviewLayoutMargins:)]) {
[cell setPreservesSuperviewLayoutMargins:NO];
}
if ([cell respondsToSelector:#selector(setLayoutMargins:)]) {
[cell setLayoutMargins:UIEdgeInsetsZero];
}
}
#end
You can create an array in which u can store selected buttons.
Example:
var selectedButtons: [Bool] = [Bool](count: N, repeatedValue: false)
In your cellForRowAtIndexPath:
if selectedButtons[indexPath.row] {
yourButton.backgroundColor = UIColor.redColor()
} else {
yourButton.backgroundColor = UIColor.whiteColor()
}
Then in your tableView didSelectRowAtIndexPath you can say:
selectedButtons[indexPath.row] = true
tableView.reloadData()
Sorry, my code is in Swift but it isn't hard to convert it to Obj-C.
Give your button a tag value in the cellForRowIndexpath method:
button.tag=indexPath.row;
and in your view did load, make the BOOL as a property in your .m file and make it accessible for the whole class
BOOL tapped =NO;
and then in your button action method:
-(IBAction)buttonMethod:(id)sender{
if(sender.tag==0){
button.backgroundColor= tapped ? [UIColor whiteColor]:[UIColor redColor];
tapped = !tapped;
}
}
Please try below code. Hope this is work for you.
-(void)aMethod:(id)sender
{
UIButton *btn = (UIButton *)sender;
if ([btn.backgroundColor isEqual:[UIColor redColor]]) {
btn.backgroundColor = [UIColor whiteColor];
}
else{
btn.backgroundColor = [UIColor redColor];
}
}
Thanks.. :)
I tried to get the solution for your question and finally i got.
First you have to change Button Type RECT to CUSTOM in Attributes Inspector.Because in button type RECT the default background color of button is BLUE.So when you click for changing the color of the button, it comes actual color(it changes to your required color) with BLUE color.So you need to set the button type as CUSTOM.
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return arrayButtonData.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
customCell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:#"cell"];
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"CustomCell" owner:self options:nil];
if (customCell==nil)
{
customCell = [nib objectAtIndex:0];
}
customCell.labelArrayListsNames.text = [NSString stringWithFormat:#"%#",[arrayButtonData objectAtIndex:indexPath.row]];
customCell.imageCircleRound.tag = indexPath.row;
NSLog(#"The custom cell button tag is - %ld",(long)customCell.imageCircleRound.tag);
NSLog(#"The label text is - %#",customCell.labelArrayListsNames.text);
[customCell.imageCircleRound addTarget:self action:#selector(cellCustomButtonClicked:)
forControlEvents:UIControlEventTouchUpInside];;
return customCell;
}
-(void)cellCustomButtonClicked:(UIButton *)sender
{
if(![sender isSelected])
{
[sender setBackgroundColor:[UIColor redColor]];
sender.Selected = YES;
}
else
{
[sender setBackgroundColor:[UIColor whiteColor]];
sender.Selected = NO;
}
}
It works fine.Check it.
enter code hereFor such problem use array of dictionary for tableview datasource array. Like this
NSMutableDictionary *datadict = [[NSMutableDictionary alloc] init];
[datadict setObject:#"Your title" forKey:#"Title"];
[datadict setObject:#"N" forKey:#"isSelected"];
[mainArray addObject: datadict]
put this code in loop for all your titles and N for isSelected key first time.
then you tableview method specially cellForRowAtIndexPath
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *Cell = [MaintableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (Cell == nil)
{
Cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
Cell.textLabel.text = [[mainArray objectAtIndex:indexPath.row] objectForKey:#"Title"];
UIButton *button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
button.tag=indexPath.row;
[button addTarget:self
action:#selector(aMethod:) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"" forState:UIControlStateNormal];
button.frame = CGRectMake(Cell.frame.size.width - 50, 10, 30, 30);
button.layer.cornerRadius = 60/2.0f;
button.layer.borderColor=[UIColor blackColor].CGColor;
if([[[mainArray objectAtIndex:indexPath.row] objectForKey:#"isSelected"] isEqualToString:#"Y"])
{
button.backgroundColor = [UIColor redColor];
}
else
{
button.backgroundColor = [UIColor whiteColor];
}
button.layer.borderWidth=2.0f;
//setting tag to button
button.tag=indexPath.row;
[Cell.contentView addSubview:button];
return Cell;
}
Then in your button action should be like
-(IBAction)aMethod :(id)sender
{
UIButton *selectedBtn = (UIButton *)sender;
if([[[mainArray objectAtIndex:[sender tag]] objectForKey:#"isSelected"] isEqualToString:#"Y"])
{
selectedBtn.backgroundColor = [UIColor whiteColor];
[[mainArray objectAtIndex:[sender tag]] removeObjectForKey:#"isSelected"];
[[mainArray objectAtIndex:[sender tag]] setObject:#"N" forKey:#"isSelected"];
}
else
{
selectedBtn.backgroundColor = [UIColor redColor];
[[mainArray objectAtIndex:[sender tag]] removeObjectForKey:#"isSelected"];
[[mainArray objectAtIndex:[sender tag]] setObject:#"Y" forKey:#"isSelected"];
}
}
you can also reload table in button action to see effect. It is good code technique to maintain multiple row selection and where data is large and realtime. By this we can get all selected rows whenever we needed on any event.

How can I send the relevant UITextField text data to the function in a collapsable UITableView?

I have this collapsable UITableView where there is a UITextField and a UIButton in the last cell in each table section. I would like to send the text in the UITextField to the function that is called by the UIButton that is next to it in the same cell, but I am baffled in how to achieve this. Thanks in advance for the help!

Give some unique tag to textfield and button by below way:
///////////////////////////////////////////
////////This is the important part/////////
///////////////////////////////////////////
UITextField *field = [[UITextField alloc] initWithFrame:CGRectMake(14, 6, 245, 31)];
self.sendButton = [[UIButton alloc] initWithFrame:CGRectMake(265, 1, 50, 40)];

[self.sendButton addTarget:self action:#selector(sendReply:) forControlEvents:UIControlEventTouchUpInside];
field.tag = self.sendButton.tag + 1;
[cell addSubview:field];
cell.accessoryView = nil;
Now on button event,
-(void) sendReply:(UIButton *)sender
{
UITextField *field = [YOOUR_TABLE_VIEW viewWithTag:sender.tag + 1];
//Do you coding here
}
Make a Custom UITableViewCell that has uitextfield and a button on it and make a protocol/delegate of that custom uitableviewcell you've created.. so you can have more control of your code and the event of your button in the future..
check this tutorial: http://www.codigator.com/tutorials/ios-uitableview-tutorial-custom-cell-and-delegates/
cheers
For this,
In cellForRowAtIndexPath: method where you are allocating the send button add one line just to give some identifier to send button as below,
[self.sendButton setAccessibilityIdentifier:[NSString stringWithFormat:#"%d#%d",indexPath.row,indexPath.section]];
Now, in sendReply: method,
//First get the row and section information
NSString *str=[sender accessibilityIdentifier];
NSArray *arr=[str componentsSeparatedByString:#"#"];
//Get the index path
NSIndexPath *iRowId =[NSIndexPath indexPathForRow:[[arr objectAtIndex:0] intValue] inSection:[arr objectAtIndex:1] intValue]];
//get the cell
UITableViewCell *objCell=(UITableViewCell*)[tblviwBasketCell cellForRowAtIndexPath:iRowId];
Now objCell will be the cell in which you have added the button and text view. so get the subviews of objCell and access the textfield to get the text.
As you say, there is a text field in each section. You should set the tag of your UIButton and UITextField same as indexPath.section.
Then, in the target method, use this tag value to get the relevant cell from the relevant section, and iterate over it's subviews to get your textField.
In the target method, you should do something like this:
- (void) sendReply:(id)sender {
int section = [(UIButton*)sender tag];
int row = [myTableView numberOfRowsInSection:section] - 1;//assuming it is the last cell in the section that contains your textField.
NSIndexPath* indexPath = [NSIndexPath indexPathForRow:row inSection:section];
UITableViewCell* cell = [myTableView cellForRowAtIndexPath:indexPath];
for (UIView* vu in cell.subviews) {
if ([vu isKindOfClass:[UITextField class]]) {
NSString* textString = [(UITextField*)vu text];
//perform any tasks you want with the text now
}
}
}
You can simply use viewWithTag:, since it does an iterative search, but all the extra code is to avoid iterating over all the cells before reaching your relevant cell.

Uncheck row automatically when table scrolled

When I scroll UITableView my tableview cells automatically uncheck. But when I press done button it give me selected rows I can't understand why is this happening.
My Tableview code is as below :
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
idArray = [[NSMutableArray alloc]init];

thanks in advance.
when ever you scroll the table
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
method executes and you have not mentioned any condition by which it can be judged that this row was previously selected or not. you have to insert a condition along with indexPath.row and check whether it is prviously selected or not
try like this ,when you scroll the tableview every time isSelectAllBtnClicked value is 0 that's why every time button changed.
when you scroll the table every time new cell created try to avoid that one
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *CellIdentifier = [NSString stringWithFormat:#"%d",indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell.selectionStyle = UITableViewCellEditingStyleNone;
cell.backgroundView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"list_row_bg.png"]] autorelease];
UILabel *catListLbl = [[UILabel alloc] initWithFrame:CGRectMake(20, 10, 310, 20)];
NSString *strValue = [[NSUserDefaults standardUserDefaults]valueForKey:#"service"];
if ([strValue isEqualToString:#"service"])
{
catListLbl.text = [serviceArray objectAtIndex:indexPath.row];
topHaderLabel.text = #"Choose Services";
}
else
{
catListLbl.text = [catArray objectAtIndex:indexPath.row];
topHaderLabel.text = #"Choose Category";
}
catListLbl.textColor = [UIColor colorWithRed:244/255.0 green:29/255.0 blue:94/255.0 alpha:1.0];
catListLbl.backgroundColor = [UIColor clearColor];
