I have some issues with how to auto self sizing native UIButton in ios. OnClick UIButton then button is auto resize with changeable text.
If anyone has a solution so help me.
thanks in advance
code:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell* cell = [tableView cellForRowAtIndexPath:indexPath];
if (cell.accessoryType == UITableViewCellAccessoryCheckmark)
{
cell.accessoryType = UITableViewCellAccessoryNone;
NSLog(#"Hide tag");
UIButton *myView = [self.textView viewWithTag:-1];
[myView removeFromSuperview];
}
else
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
NSLog(#"Show tag");
UIButton *myView = [[UIButton alloc] initWithFrame:CGRectMake(10.0f, 10.0f, 40.0f, 20.0f)];
[myView setBackgroundColor:[UIColor redColor]];
[myView setTag:-1];
[self.textView addSubview:myView];
NSLog(#"add tag");
self.textView.text = [NSString stringWithFormat:#"%#%#%#", self.textView.text,cell.textLabel.text, #"\n"];
}
}

I'm creating a UISwitch programmatically in one of the tableview datasource function(cell for row at index). when I'm scrolling the table view, the OFF state switches are malfunctioned(UI) two rounds appeared. Attaching the screenshot of the switch.
Appreciate your help!
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
UILabel *title = (UILabel*)[cell viewWithTag:80];
UILabel *description = (UILabel*)[cell viewWithTag:81];
UIView *innerView = (UIView *)[cell viewWithTag:82];
innerView.layer.borderColor=[[UIColor colorWithRed:229/255.0f green:229/255.0f blue:229/255.0f alpha:1.0] CGColor];
innerView.layer.borderWidth = 2.0f;
NSDictionary *displayDict = scenarioListsArray[indexPath.row];
title.text =[displayDict objectForKey:#"name"];
description.text = [displayDict objectForKey:#"description"];
UISwitch *myswitch = [[UISwitch alloc]initWithFrame:CGRectMake(cell.contentView.frame.size.width-60, (cell.contentView.frame.size.height/2)-20 , 100, 100)];
myswitch.onTintColor = [UIColor colorWithRed:25/255.0f green:122/255.0f blue:66/255.0f alpha:1];
[cell.contentView addSubview:myswitch];
myswitch.tag = indexPath.row;
[myswitch addTarget:self action:#selector(cellButtonClickAction:) forControlEvents:UIControlEventValueChanged];
if ([[displayDict objectForKey:#"status"] isEqualToString:#"ACTIVE"]) {
[myswitch setOn:YES animated:YES];
}
else
{
[myswitch setOn:NO animated:YES];
}
return cell;
}
I have faced the same issue and fixed with following code before creating switch
for(UIView *subView in cell. contentView.subviews){
if ([subView isKindOfClass:[UISwitch class]]) {
[subView removeFromSuperview];
}
}
Or
static NSString *TableIdentifier = #"YourCellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:TableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:TableIdentifier];
//place your all UI elements code here.
}
I have updated your code, try this will work for you,
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
UILabel *title = (UILabel*)[cell viewWithTag:80];
UILabel *description = (UILabel*)[cell viewWithTag:81];
UIView *innerView = (UIView *)[cell viewWithTag:82];
innerView.layer.borderColor=[[UIColor colorWithRed:229/255.0f green:229/255.0f blue:229/255.0f alpha:1.0] CGColor];
innerView.layer.borderWidth = 2.0f;
NSDictionary *displayDict = scenarioListsArray[indexPath.row];
title.text =[displayDict objectForKey:#"name"];
description.text = [displayDict objectForKey:#"description"];
UISwitch *myswitch = [cell.contentView viewWithTag:indexPath.row+597];
if(mySwitch == nil){
myswitch = [[UISwitch alloc]initWithFrame:CGRectMake(cell.contentView.frame.size.width-60,(cell.contentView.frame.size.height/2)-20 , 100, 100)];
[cell.contentView addSubview:myswitch];
[myswitch addTarget:self action:#selector(cellButtonClickAction:) forControlEvents:UIControlEventValueChanged];
}
myswitch.onTintColor = [UIColor colorWithRed:25/255.0f green:122/255.0f blue:66/255.0f alpha:1];
myswitch.tag = indexPath.row+597; //597 is extra number added to tag
if ([[displayDict objectForKey:#"status"] isEqualToString:#"ACTIVE"]) {
[myswitch setOn:YES animated:YES];
}
else
{
[myswitch setOn:NO animated:YES];
}
return cell;
}
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

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];

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.
I want a button to show when i select a cell, when i select the same cell or another cell i want the button to hide. So one button should only be visible at a time.
What i have:
in my .h file:
#property (strong, nonatomic) NSIndexPath *isselectednow;
and my .m file:
Viewdidload:
self.isselectednow = [NSIndexPath indexPathForRow:7 inSection:1];
cellForRowAtIndexPath:

}
//[cell addSubview:[self drawSeparationView:(indexPath.row)]];
UILabel *DateName = (UILabel *)[cell viewWithTag:100100];
DateName.textColor = [UIColor blackColor];
//DateName.text = [NSString stringWithFormat:#"%ld",(long)indexPath.row ];
DateName.text = objects[indexPath.row];
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self
action:#selector(buttonOnCellPressed:)
forControlEvents:UIControlEventTouchDown];
[button setTitle:#"Update" forState:UIControlStateNormal];
button.frame = CGRectMake(DEVICE_SIZE.width - 60, 18, 55, 15);
[cell addSubview:button];
if ([indexPath compare:self.isselectednow] == NSOrderedSame) {
button.hidden = NO;
}
else{
button.hidden = YES;
}
UILabel *lbl1 = (UILabel *)[cell viewWithTag:100101];

}
didSelectRowAtIndexPath:
[tableView beginUpdates];
if ([indexPath compare:self.isselectednow] == NSOrderedSame) {
self.isselectednow = nil;
}
else{
self.isselectednow = indexPath;
}
[tableView endUpdates];
//[tableView reloadData];
From the docs about beginUpdates:
Call this method if you want subsequent insertions, deletion, and selection operations (for example, cellForRowAtIndexPath: and indexPathsForVisibleRows) to be animated simultaneously.
Although you've changed the isSelectedNow boolean, you haven't actually specified any insertion, deletion, or selection operations between beginUpdates and endUpdates. So you're not actually beginning or ending any updates to the cells' content with that code.
I'm not sure what you're trying to do, but taking out [tableView beginUpdates]; and [tableView beginUpdates]; and reinserting [tableView reloadData]; would result in a proper data reload.
Edit:
Aside from that, the problem is that you're reusing your cells with dequeueReusableCellWithIdentifier:, but you're adding a new UIButton subview each time, so you're basically putting each new UIButton over the old. I suggest doing what you've done for all your labels and textfields in cellForRowAtIndexPath: -- reuse your update button by adding it to your custom table view cell and accessing it with viewWithTag:.
I have a UITableview in this view i created uiwebview for each cell. When i tap on a cell i want the view of UIWebView. How to achieve this??
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString * CellIdentifier = #"Cell";
UITableViewCell *cell;
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
if(cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
[[cell.contentView subviews] makeObjectsPerformSelector:#selector(removeFromSuperview)];
cell.accessoryType = UITableViewCellAccessoryNone;
UIView *customView = [[UIView alloc]init];
customView.transform = CGAffineTransformMakeRotation(M_PI_2);
[customView setFrame:CGRectMake(0, 0, 1024, 768)];
[customView setBackgroundColor:[UIColor clearColor]];
UIWebView *menuWeb = [[UIWebView alloc]init];
[menuWeb setFrame:CGRectMake(0, 0, 768, 1024)];
[menuWeb setDelegate:self];
[menuWeb setUserInteractionEnabled:YES];
[menuWeb.scrollView setScrollEnabled:NO];
[menuWeb setScalesPageToFit:YES];
NSURL *url = [NSURL fileURLWithPath:[urlArr objectAtIndex:indexPath.row]];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[menuWeb loadRequest:request];
[customView addSubview:menuWeb];
[cell.contentView addSubview:customView];
[cell setBackgroundColor:[UIColor clearColor]];
return cell;
}
in cellForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
....
UIView *customView = [[UIView alloc]init];
customView.tag = 100;
....
return cell;
}
and in
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
UIView *customView = [cell.contentView viewWithTag:100];
for (id view in customView.subViews) {
if ([view isKindOfClass:[UIWebView class]]) {
UIWebView *menuWeb = (UIWebView *)view;
}
}
}
hope this will help
There are a couple of ways you can achieve this.
The simplest way would be to assign a tag to the webview and then retreive it when the cell is tapped.
When you create the cell add:
[menuWeb setTag:SOME_CONSTANT_NUMBER];
Then inside the webview delegate's didSelectRowAtIndexPath method retrieve the cell and it's webView:
UITableViewCell *cell = [tableVoew cellForRowAtIndexPath:indexPath];
UIWebView *webView = [cell viewWithTag:SOME_CONSTANT_NUMBER];
Try this one, in cellForRowAtIndexPath tag CustomView and webview so that you can retrieve using tag-
......
customView.tag = 111;
......
webView.tag = 222;
.......
Then in didSelectRowAtIndexPath
UITableViewCell *cell = (UITableViewCell *) [tableView cellForRowAtIndexPath:indexPath];
UIView *customView = [cell.contentView viewWithTag:111];
Use viewWithTag to find out webview
UIWebView *wView = [customView viewWithTag:222];
Or iterate over custom view to find out webview
UIWebView *wView = nil;
for ((id) subView in [customView subviews]) {
if ([subView isKindOfClass:[UIWebView class]]){
//Found WebView
wView =(UIWebView *) subView;
break;
}
}
I have table view in side bar which is similar to facebook app. In my sidebar tableview i have imageview in each row. I want the imageview will be changed when i clicked the cell and it will be retain while for selecting another cell. Here is my code
- (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]autorelease];
}
[[cell.contentView subviews] makeObjectsPerformSelector:#selector(removeFromSuperview)];
UIView * contentView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 60)];
UIImageView * cellImg = [[UIImageView alloc]initWithFrame:CGRectMake(5,8,259, 60)];
[cellImg setImage:[UIImage imageNamed:[menuArr objectAtIndex:indexPath.row]]];
[contentView addSubview:cellImg];
[contentView setBackgroundColor:[UIColor clearColor]];
[cell.contentView addSubview:contentView];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
return cell;
}
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
delegate.sideBarSelectedIndex = indexPath.row;
NSLog(#"delegate.sideBarSelectedIndex: %d",delegate.sideBarSelectedIndex);
[UIView commitAnimations];
if (self.sidebarDelegate) {
NSObject *object = [NSString stringWithFormat:#"ViewController%d", indexPath.row];
[self.sidebarDelegate sidebarViewController:self didSelectObject:object atIndexPath:indexPath];
[delegate.firstLensePageObj timerFunction:indexPath.row];
}
}
Try this in your didSelectRowAtIndexPath delegate method :-
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
cell.imageView.image = [UIImage imageNamed:#"yourImage"];
Try this in cellForRowAtIndexPath.
UIImageView *selectedImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Your Image"]];
cell.selectedBackgroundView = selectedImageView;
Need to capture the selected indexpath in didSelectRowAtIndexPath: method and need to reload the tableview in that method. In cellForRowAtIndexPath need to check the selected index with current index.
