I am fetching the data from UITableViewCell and am storing into string is countryString. I want to change the button title with country string but its not working, i thought it is a simple issue, but am struggling from last 2 hours. still I cant find the solution why is not working
countryButton=[[UIButton alloc]initWithFrame:CGRectMake(145, 145, 100, 30)];
countryButton.backgroundColor=[UIColor whiteColor];
[countryButton setTitle:CountryString forState:UIControlStateNormal];
countryButton.titleLabel.textColor=[UIColor blackColor];
[countryButton addTarget:self action:#selector(countryTable) forControlEvents:UIControlEventTouchUpInside];
[notesView addSubview:countryButton];
-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath
{
jsonDict = [newarray objectAtIndex:indexPath.row];
CountryString=[jsonDict objectForKey:#"countryName"];
NSLog(#"country is %#", CountryString);
CountryTableview.hidden=YES;
}
try this
-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath
{
jsonDict = [newarray objectAtIndex:indexPath.row];
CountryString=[jsonDict objectForKey:#"countryName"];
NSLog(#"country is %#", CountryString);
[countryButton setTitle:CountryString forState:UIControlStateNormal];
countryButton.titleLabel.textColor=[UIColor blackColor];
CountryTableview.hidden=YES;
}
assume that its your str
CountryString =#"XXXX";
UIButton *countryButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; //or button type custom
[countryButton addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[countryButton setFrame:CGRectMake(145, 145, 100, 30)];
[countryButton setTitle: CountryString forState:UIControlStateNormal];
[countryButton setExclusiveTouch:YES];
countryButton.backgroundColor=[UIColor whiteColor];
countryButton.titleLabel.textColor=[UIColor blackColor];
[self.view addSubview: countryButton]; //whatever u need self.view or notesView
-(void) buttonClicked:(UIButton*)sender
{
NSLog(#"you clicked on button %#", sender.tag);
}

I am trying to create a UIButton in a class that is a subclass of UIButton. The reason for this is that it would be easier for my app to do this. I am wondering if it is possible. I am able to create the button, but the action is not working. My selector exists, but is not getting called.
UIButton *button2 = [[UIButton alloc] initWithFrame:CGRectMake(0, kThumbSide - 350, kThumbSide, 16)];
[button2 setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
[button2 setTitle:[NSString stringWithFormat:#"%#", [data objectForKey:#"username"]] forState:UIControlStateNormal];
[button2 sizeToFit];
button2.backgroundColor = [UIColor clearColor];
button2.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
button2.font = [UIFont fontWithName:#"Arial" size:15];
[button2 addTarget:delegate action:#selector(showUserViews) forControlEvents:UIControlEventTouchUpInside];
[self addSubview:button2];
Hey you are creating an Object of UIButton class not any Class clear???
and your target method are getting wrong Delegate.
try it
[button2 addTarget:self action:#selector(showUserViews) forControlEvents:UIControlEventTouchUpInside];
replace delegate with self for getting showUserViews method in same class
I haven't see any UIButton subclass here, perhaps you've asked your question wrong.
Any way you should do this:
- (void) viewDidLoad {
[super viewDidLoad]
UIButton *b = [[UIButton alloc]initWithFrame:YOUR_DESIRED_FRAME];
[b setBackgroundColor:[UIColor redColor]]
[b addTarget:self action:#selector(bPressed:) forControlEvents:UIControlEventTouchUpInside]
}
- (void)bPressed:(UIButton *)sender {
NSLog(#"b button pressed")
}
Actually I just want to make it like:
When user taps button 1 , it stores its value in a string and when user selects another button; it also store its value also and when he de-select the button again it must be removed from string and also from uiLabel
How it will be possible ?
I have to know all possible ways
1) Declare in your ViewController.m
#interface ViewController ()
{
UIButton *button1;
UIButton *button2;
NSString *btn1String;
NSString *btn2String;
BOOL btn1isClicked;
BOOL btn2isClicked;
UILabel *label;
}
2) Buttons and label (can be in your ViewDidLoad)
btn1isClicked = NO;
btn2isClicked = NO;
//initialy set to nothing
btn1String = #"";
btn2String = #"";
//create first button
button1 = [[UIButton alloc] initWithFrame:CGRectMake(0, 50, 200, 50)];
//button 1 clicked
[button1 addTarget:self action:#selector(button1Clicked) forControlEvents:UIControlEventTouchUpInside];
[button1 setTitle:#"Button One" forState:UIControlStateNormal];
[button1 setTitleColor:[UIColor purpleColor] forState:UIControlStateNormal];
[self.view addSubview:button1];
//create second button
button2 = [[UIButton alloc] initWithFrame:CGRectMake(0, 150, 200, 50)];
//button 2 clicked
[button2 addTarget:self action:#selector(button2Clicked) forControlEvents:UIControlEventTouchUpInside];
[button2 setTitle:#"Button Two" forState:UIControlStateNormal];
[button2 setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
[self.view addSubview:button2];
//create label
label = [[UILabel alloc] initWithFrame:CGRectMake(0, 300, 320, 50)];
[label setText:#""];
[self.view addSubview:label];
3) Button Clicked methods
- (void) button1Clicked
{
if (!btn1isClicked)
{
//set bool to yes
btn1isClicked = YES;
[button1 setTitle:#"Button One Clicked" forState:UIControlStateNormal];
//set button 1 value
btn1String = #"btn1value";
}
else
{
//set bool to no
btn1isClicked = NO;
[button1 setTitle:#"Button One" forState:UIControlStateNormal];
btn1String = #"";
}
//update label
[label setText:[NSString stringWithFormat:#"%# %#", btn1String, btn2String]];
}
- (void) button2Clicked
{
if (!btn2isClicked)
{
btn2isClicked = YES;
[button2 setTitle:#"Button Two Clicked" forState:UIControlStateNormal];
//set button 2 value
btn2String = #"btn2value";
}
else
{
btn2isClicked = NO;
[button2 setTitle:#"Button Two" forState:UIControlStateNormal];
btn2String = #"";
}
//update label
[label setText:[NSString stringWithFormat:#"%# %#", btn1String, btn2String]];
}
Hope this helps
-(IBActions)buttonDidTap:(UIButton*)btn { //the target selector the button is attached to
if ([btn isSelected]) { //check if the button is selected
NSString *buttonTitleValue = btn.currentTitle; //Get the button title value
myLabel.text = buttonTitleValue; //set the UIlabel text to the title of the button
}
}

I've added a button to section header which shows a view on clicking it. My need is that I've to show an "Up-arrow" image while view is shown and "Down-arrow" image when view is hidden.
How can I achieve this? Please help me ...
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{
UIButton *btn=[UIButton buttonWithType:UIButtonTypeCustom];
[btn setFrame:CGRectMake(0, 0, 316, 60)];
[btn setTag:section];
[aView addSubview:btn];
[btn addTarget:self action:#selector(sectionTapped:) forControlEvents:UIControlEventTouchDown];
btn.backgroundColor=[UIColor clearColor];
}
I will suggest that you can have 2 images - 1 for 'Up' and 1 for 'Down' arrow.
Set default image to the btn for state UIControlStateNormal and set the other image for state UIControlStateSelected.
Now in your sectionTapped: method just change the state of the button.
So when you show or hide your view you need to set the button selected YES/NO.
Hope this helps.
I had done this before in one of my app.
Take this code as Reference
1.Specific Method.
- (void)methodName:(UIButton *)sender
{
int i = [sender.titleLabel.text intValue];
NSNumber *numb;
if(i == 0)
{
numb = [NSNumber numberWithBool:NO];
sender.titleLabel.text = #"1";
[sender setImage:[UIImage imageNamed:#"down.png"] forState:UIControlStateNormal];
[sender setImage:[UIImage imageNamed:#"up.png"] forState:UIControlStateHighlighted];
}
else
{
numb = [NSNumber numberWithBool:YES];
sender.titleLabel.text = #"0";
[sender setImage:[UIImage imageNamed:#"up.png"] forState:UIControlStateNormal];
[sender setImage:[UIImage imageNamed:#"down.png"] forState:UIControlStateHighlighted];
}
}
2.Setting UIButton Programatically in UITabelview viewForHeaderInSection.
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(240, 20, 30, 30)];
[button addTarget:self
action:#selector(methodName:)
forControlEvents:UIControlEventTouchDown];
button.tag = section;
if([[sectionsArray objectAtIndex:section] boolValue])
{
[button setImage:[UIImage imageNamed:#"up.png"] forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:#"down.png"] forState:UIControlStateHighlighted];
button.titleLabel.text = #"0";
}
else
{
[button setImage:[UIImage imageNamed:#"down.png"] forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:#"up.png"] forState:UIControlStateHighlighted];
button.titleLabel.text = #"1";
}
You can trying using BOOL to check if the button has been pressed or not and animate to rotate the image in your button to point up or down.
-(IBAction)dropdownBtnClicked:(id)sender
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
if (!isDropdownEnabled)
{
//BOOL - checking if the button has been pressed or not
isDropdownEnabled=TRUE;
drpDwnBtn.transform=CGAffineTransformMakeRotation(270/180*M_PI);
}
else
{
isDropdownEnabled=FALSE;
drpDwnBtn.transform=CGAffineTransformMakeRotation(0);
}
[UIView commitAnimations];
}
In my iOS application, I have to change image as per button click.
I have to perform togling for single UIButton which I have generated from loop for different frame
It is working fine if I perform action on single button, if I have performing action for multiple button the image is not properly changing as per button action
Here is my button
btnFullScreen = [[UIButton alloc] init];
[btnFullScreen setBackgroundImage:[UIImage imageNamed:#"open icon.png"] forState:UIControlStateNormal];
[btnFullScreen setFrame:CGRectMake(self.view.frame.size.width-30,8,16,14)];
[btnFullScreen setBackgroundImage:[UIImage imageNamed:#"close icon.png"] forState:UIControlStateSelected];
[btnFullScreen addTarget:self action:#selector(showPopUp:) forControlEvents:UIControlEventTouchUpInside];
btnFullScreen.autoresizingMask=UIViewAutoresizingFlexibleLeftMargin|UIViewAutoresizingFlexibleBottomMargin;
[self.view addSubview:btnFullScreen];
Here is my button action code
-(void)showPopUp:(id)sender{
if ([sender isSelected]) {
[sender setImage:[UIImage imageNamed:#"open icon.png"] forState:UIControlStateNormal];
[sender setSelected:NO];
}else {
[sender setImage:[UIImage imageNamed:#"close icon.png"] forState:UIControlStateSelected];
[sender setSelected:YES];
}
[self.parent.parent addPopOversExcept:self.parent];
}
Thanks
I had done this before in one of my app.
I was creating button in each tableview cell.
So,Take this code as Reference.
1.Specific Method.
- (void)methodName:(UIButton *)sender
{
int i = [sender.titleLabel.text intValue];
NSNumber *numb;
if(i == 0)
{
numb = [NSNumber numberWithBool:NO];

[sender setImage:[UIImage imageNamed:#"down.png"] forState:UIControlStateNormal];
[sender setImage:[UIImage imageNamed:#"up.png"] forState:UIControlStateHighlighted];
}
else
{
numb = [NSNumber numberWithBool:YES];
sender.titleLabel.text = #"0";
[sender setImage:[UIImage imageNamed:#"up.png"] forState:UIControlStateNormal];
[sender setImage:[UIImage imageNamed:#"down.png"] forState:UIControlStateHighlighted];
}
}
2.Setting UIButton Programatically in UITabelview viewForHeaderInSection.
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(240, 20, 30, 30)];
[button addTarget:self
action:#selector(methodName:)
forControlEvents:UIControlEventTouchDown];
button.tag = section;
if([[sectionsArray objectAtIndex:section] boolValue])
{

[button setImage:[UIImage imageNamed:#"down.png"] forState:UIControlStateHighlighted];
button.titleLabel.text = #"0";
}
else
{
[button setImage:[UIImage imageNamed:#"down.png"] forState:UIControlStateNormal];

In my app i have a scroll-view and a table-View added as a sub-view and on this scroll view i have multiple menu buttons (UI Button) added as sub-view to my scroll-view.i want to load the table-View with different arrays depending on respective menu button is tapped.Any Ideas?
- (void)viewDidLoad
{
[super viewDidLoad];
[self PutButtoninScrollView:7];
}
-(void)PutButtoninScrollView:(int)numberOfbuttons
{
myButton1=[[UIButton alloc]init];
myButton1= [UIButton buttonWithType:UIButtonTypeCustom];
myButton1.frame=CGRectMake(5, 5, 70, 30);
[myButton1 setTitle:#"दुनिया" forState:UIControlStateNormal];
[myButton1 setTag:1];
myButton1.backgroundColor=[UIColor blackColor];
[myButton1 addTarget:self action:#selector(ListViewAction:) forControlEvents:UIControlEventTouchUpInside];
[self.myScrollView addSubview:myButton1];
myButton2=[[UIButton alloc]init];
myButton2= [UIButton buttonWithType:UIButtonTypeRoundedRect];
myButton2.frame=CGRectMake(80, 5, 70, 30);
[myButton2 setTitle:#"India" forState:UIControlStateNormal];
[myButton2 addTarget:self action:#selector(ListViewAction:) forControlEvents:UIControlEventTouchUpInside];
[self.myScrollView addSubview:myButton2];
[self.myScrollView setContentSize:CGSizeMake(160, 35)];
_myScrollView.backgroundColor=[UIColor redColor];
[self.view addSubview:self.myScrollView];
}
-(void)ListViewAction:(id)sender
{
NSLog(#"sucessful");
if ([myButton.currentTitle isEqualToString:#"दुनिया"])
{
NSLog(#"successful again 1");
}
else if ([myButton.currentTitle isEqualToString:#"भारत"])
{
NSLog(#"successful again 2");
}
}
problem is when i execute the code
"successful" is displayed. that means ListViewAction method is getting called but my if statement is never executed.
try this
-(void)PutButtoninScrollView:(int)numberOfbuttons
{
xPosition=5;
for(int i=0;i<numberOfbuttons;i++)
{
myButton= [UIButton buttonWithType:UIButtonTypeRoundedRect];
myButton.frame=CGRectMake(xPosition, 5, 70, 30);
myButton.backgroundColor=[UIColor redColor];
[myButton setTitle:[NSString stringWithFormat:#"%d",i] forState:UIControlStateNormal];
[myButton setTag:i];
[myButton addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[self.myScrollView addSubview:myButton];
xPosition+=75;
}
[self.myScrollView setContentSize:CGSizeMake(xPosition,35)];
_myScrollView.backgroundColor=[UIColor redColor];
[self.view addSubview:self.myScrollView];
}
