I need a pre-iOS UIButton with border in my app. I use:
btn.layer.borderColor = [UIColor blackColor].CGColor;
btn.layer.borderWidth = 1.0;
btn.layer.cornerRadius = 10;
This works ok but on tap the border does not flash(button highlight state). Any way to easily implement this ?
Implement this when creating the button:
[self.botonConfigurar addTarget:self action:#selector(setBgColorForButton:) forControlEvents:UIControlEventTouchDown];
[self.botonConfigurar addTarget:self action:#selector(clearBgColorForButton:) forControlEvents:UIControlEventTouchDragExit];
[self.botonConfigurar addTarget:self action:#selector(setBgColorForButton:) forControlEvents:UIControlEventTouchDragEnter];
and these 2 functions:
-(void)setBgColorForButton:(UIButton*)sender {
[self.botonConfigurar setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
self.botonConfigurar.layer.backgroundColor = [UIColor colorWithRed:89/255.0 green:194/255.0 blue:237/255.0 alpha:1.0].CGColor;
}
-(void)clearBgColorForButton:(UIButton*)sender {
[self.botonConfigurar setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
self.botonConfigurar.layer.backgroundColor = [UIColor colorWithRed:61/255.0 green:169/255.0 blue:222/255.0 alpha:1].CGColor;
}
Do whatever you want with the button inside these functions.
PD: Make your button a [UIButton buttonWithType:UIButtonTypeCustom]
PD2: In clearBgColorForButton:sender write your UIButton's original parameters.
This is Just Example
[button setBackgroundImage:[self imageWithColor:[UIColor blueColor]] forState:UIControlStateHighlighted];

I have created the array of UIButtons , having the same action,
if i click the first button, the first button Colour should be change, other button Colour should not be changed. how to achieve this?
for(titleStr in titleArray){
actionButton = [UIButton buttonWithType:UIButtonTypeCustom];
[actionButton addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
actionButton.tag = count;
[actionButton setTitle:titleArray[count] forState:UIControlStateNormal];
[actionButton setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
[actionButton setBackgroundColor:[UIColor clearColor]];//[UIColor greenColor]]; // AJS 3.3 change
CGSize expectedTitleSize = [actionButton.titleLabel sizeThatFits:maximumLabelSize];
CGRect buttonframe;
buttonframe=CGRectMake(contentOffset,0, expectedTitleSize.width+5.0, expectedTitleSize.height+25);
actionButton.frame = buttonframe;
[titlewidthArray addObject:[NSNumber numberWithFloat:expectedTitleSize.width]];
[contentoffsetArray addObject:[NSNumber numberWithFloat:contentOffset+3.0]];
if(count==0){
actionButton.titleLabel.font=[UIFont fontWithName:#"HelveticaNeue-Medium" size:15.0];
[actionButton setSelected:YES];
tempObj = actionButton;
}else {
actionButton.titleLabel.font=[UIFont fontWithName:#"HelveticaNeue-Medium" size:15.0];
}
[titleScrollView addSubview:actionButton];
contentOffset += actionButton.frame.size.width+5.0;
titleScrollView.contentSize = CGSizeMake(contentOffset, titleScrollView.frame.size.height);
// Increase the count value
count++;
}
-(void)buttonTapped:(id)sender {
if([sender tag]==0){
UIButton *tappedButton = (UIButton *)sender;
[actionButton setTitleColor:[UIColor yellowColor] forState:UIControlStateNormal];
actionButton.titleLabel.textColor = [UIColor whiteColor];
[actionButton setTitleColor:[UIColor whiteColor] forState:UIControlStateDisabled];
[tappedButton setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
}
}
Thanks advance
for that you have to take one extra UIButton Object in you header file.
While user click on any button you have to store that selected Button in refbutton object and use like below.
#interface YourViewController ()
{
UIButton *btnSelected;
}
Now Move to your Button Action:
-(IBAction)buttonTapped:(UIButton *)sender {
if(_btnSelected){
_btnSelected.titleLabel.textColor = [UIColor blackColor];
}
_btnSelected = sender;
sender.titleLabel.textColor = [UIColor whiteColor];
}
Hope this will help you.
hi I have some code that creates two buttons and when a button is pressed an trigger is set and it changes the background and the text colour.
How could i make it so that once one is pressed the other cannot be pressed.
This creates the buttons
//learnmore button
UIButton *learnmorebutton = [UIButton buttonWithType:UIButtonTypeCustom];
[self.view addSubview:learnmorebutton];
learnmorebutton.backgroundColor = [UIColor colorWithWhite:0.0 alpha:0.3];
learnmorebutton.frame = CGRectMake(0.0, 518.0, 159.0, 50.0);
[learnmorebutton setTitle:#"learn more" forState:UIControlStateNormal];
[learnmorebutton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
learnmorebutton.titleLabel.font = [UIFont fontWithName:#"Helvetica Light" size:17.0];
//signup button
UIButton *signup = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[self.view addSubview:signup];
signup.backgroundColor = [UIColor colorWithWhite:0.0 alpha:0.3];
signup.frame = CGRectMake(162.0, 518.0, 160.0, 50.0);
[signup setTitle:#"sign up" forState:UIControlStateNormal];
signup.titleLabel.font = [UIFont fontWithName:#"Helvetica Light" size:17.0];
signup.titleLabel.textColor = [UIColor whiteColor];
These are the two triggers
[learnmorebutton addTarget:self action:#selector(learnMoreClickEvent:) forControlEvents:UIControlEventTouchUpInside];
[signup addTarget:self action:#selector(signupClickEvent:) forControlEvents:UIControlEventTouchUpInside];
These are the two events
- (void)learnMoreClickEvent:(UIButton *)sender
{
//sender is the button that was tapped
[sender setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
sender.backgroundColor = [UIColor whiteColor];
}
- (void)signupClickEvent:(UIButton *)sender
{
//sender is the button that was tapped
[sender setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
sender.backgroundColor = [UIColor whiteColor];
}
thanks all ...
You start by keep a reference to the button, preferably properties on the viewController that creates these buttons.
#interface MyViewController : UIViewController
#property (nonatomic, strong) UIButton *learnmorebutton;
#property (nonatomic, strong) UIButton *signup;
#end;
Then in the method either disable the button:
<button>.enabled = NO:
Or hide it:
<button>.hidden = YES:
like rckoenes mentioned you can declare those UIButton as properties and do that.. or
Assign Tags like this
//learnmore button
UIButton *learnmorebutton = [UIButton buttonWithType:UIButtonTypeCustom];
learnmorebutton.tag = 10;
learnmorebutton.backgroundColor = [UIColor colorWithWhite:0.0 alpha:0.3];
learnmorebutton.frame = CGRectMake(0.0, 518.0, 159.0, 50.0);
[learnmorebutton setTitle:#"learn more" forState:UIControlStateNormal];
[learnmorebutton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
learnmorebutton.titleLabel.font = [UIFont fontWithName:#"Helvetica Light" size:17.0];
[learnmorebutton addTarget:self action:#selector(learnMoreClickEvent:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:learnmorebutton];
//signup button
UIButton *signup = [UIButton buttonWithType:UIButtonTypeRoundedRect];
signup.tag = 20;
signup.backgroundColor = [UIColor colorWithWhite:0.0 alpha:0.3];
signup.frame = CGRectMake(162.0, 518.0, 160.0, 50.0);
[signup setTitle:#"sign up" forState:UIControlStateNormal];
signup.titleLabel.font = [UIFont fontWithName:#"Helvetica Light" size:17.0];
signup.titleLabel.textColor = [UIColor whiteColor];
[self.view addSubview:signup];
[signup addTarget:self action:#selector(signupClickEvent:) forControlEvents:UIControlEventTouchUpInside];
By Using tags to access the buttons
- (void)learnMoreClickEvent:(UIButton *)sender
{
UIButton *signUp = (UIButton*)[self.view viewWithTag:20]
signUp.enabled = NO;
//sender is the button that was tapped
[sender setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
sender.backgroundColor = [UIColor whiteColor];
}
- (void)signupClickEvent:(UIButton *)sender
{
UIButton *learnmorebutton = (UIButton*)[self.view viewWithTag:10]
learnmorebutton.enabled = NO;
//sender is the button that was tapped
[sender setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
sender.backgroundColor = [UIColor whiteColor];
}
Hope this gives you an Idea.
Basically if your looking for toggling, you can always use UISegementControl. I mean it depends on your requirements.
Set the enabled property of the button you want to disable to NO: <button>.enabled = NO;
I want the aButton change the titleColor from WHITE to RED when I click
But when I click other button,I want aButton change back to WHITE
How can I do that?
Here is the code I write,But It not work as I want.
[aButton setTitleColor:[UIColor redColor] forState:UIControlStateSelected];
Use setSelected: to change the selection state of button.
in viewDidLoad:
[aButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[aButton setTitleColor:[UIColor redColor] forState:UIControlStateSelected];
[bButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[bButton setTitleColor:[UIColor redColor] forState:UIControlStateSelected];
aButton.selected = YES;
- (IBAction)aButton_or_bButtonClicked:(id)sender {
if(aButton.selected) {
aButton.selected = NO;
bButton.selected = YES;
}
else {
aButton.selected = YES;
bButton.selected = NO;
}
}
Should work like this:
- (IBAction)aButtonClicked:(id)sender {
[aButton setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
}
- (IBAction)bButtonClicked:(id)sender {
[aButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
}
I'm trying to programmatically create a UIButton. However by default it's turning up white (which is the default color for my navigation bar, I feel that's relevant). I want it to just be Apple's default blue color in iOS7. I've managed to change the color for it's default state, but the moment I select it the text becomes white again. I cannot figure out how to keep it blue.
Could someone please explain to me how I can programmatically create a UIButton and have it act the same as though I created it in storyboard?
Current code:
UIButton *cancelButton = [UIButton buttonWithType:UIButtonTypeCustom];
cancelButton.frame = CGRectMake(320 - 150, 0, 140, 40);
[cancelButton setTitle:#"Cancel" forState:UIControlStateNormal];
cancelButton.titleLabel.tintColor = [UIColor colorWithRed:0.0 green:122.0/255.0 blue:1.0 alpha:1.0];
cancelButton.titleLabel.textColor = [UIColor colorWithRed:0.0 green:122.0/255.0 blue:1.0 alpha:1.0];
Thank you.
Try this code :
UIButton *cancelButton = [UIButton buttonWithType:UIButtonTypeCustom];
[cancelButton setFrame:CGRectMake(320 - 150, 0, 140, 40)];
[cancelButton setBackgroundColor:[UIColor clearColor]];
[cancelButton setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
[cancelButton setTitleColor:[UIColor blueColor] forState:UIControlStateHighlighted]; // This will helps you during click time title color will be blue color
[cancelButton setTitle:#"Cancel" forState:UIControlStateNormal];
[cancelButton addTarget:self action:#selector(button_Action) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:cancelButton];
Just tried with
[cancelButton setTitleColor:[UIColor colorWithRed:0.0 green:122.0/255.0 blue:1.0/255.0 alpha:1.0] forState:UIControlStateNormal];
For more information read official documentation of UIButton.
Have you tried this
[cancelButton setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
[cancelButton setTitleColor:[UIColor blueColor] forState:UIControlStateSelected];
This will solve your problem,
[cancelButton setTitleColor:YOUR COLOR forState:SPECIFIED STATE];
The state values are :
UIControlStateNormal
UIControlStateHighlighted
UIControlStateDisabled
UIControlStateSelected
Try using
- (void)setTitleColor:(UIColor *)color forState:(UIControlState)state
for specifying colors for all the required states.
Swift:
let button = UIButton (type: UIButtonType.system)
This will create a button that uses the standard tint color just like a button added to a storyboard in interface builder.
I am using xcode 4.6 to develop an app. Here i want to add UIButton programmatically to UIscrollview. This is the code i follow.
UIButton *bt =[[UIButton alloc]initWithFrame:frame];
bt=[UIButton buttonWithType:UIButtonTypeCustom];
[bt setTitle:#"Custom Button" forState:UIControlStateNormal];
[bt addTarget:self action:#selector(userTappedOnLink:) forControlEvents:UIControlEventTouchUpInside];
bt.backgroundColor = [UIColor grayColor];
bt.titleLabel.textColor=[UIColor blueColor];
[self.mainscrollview addSubview:bt];
[self.mainscrollview bringSubviewToFront:bt];
Now the problem is that Button gets disappeared (technically its textcolor becomes white) on click. I checked keeping UIscrollview color to red that th button was still in the view but i cant get the reason why its text color changed and how do i undo dis.
Basically I wan to create a clickable link using UIbutton.
I know uitextview approach (datadetectortype) but its of no use as i want to show different text in the label for the link and the actual link.
Note: The textcolor doesnt change back to blue and remains white only.
Thanks in advance.
Try the below code
UIButton *bt =[UIButton buttonWithType:UIButtonTypeCustom];
bt.frame = CGRectMake(50.0, 50.0, 100.0, 50.0);
[bt setTitle:#"Custom Button" forState:UIControlStateNormal];
[bt addTarget:self action:#selector(userTappedOnLink:) forControlEvents:UIControlEventTouchUpInside];
bt.backgroundColor = [UIColor grayColor];
bt.titleLabel.textColor=[UIColor blueColor];
[self.scrollTest addSubview:bt];
-(void)userTappedOnLink:(UIButton*)sender
{
NSLog(#"Test ..");
[self performSelector:#selector(changeBtnTextColor:) withObject:sender afterDelay:1.0];
}
-(void)changeBtnTextColor:(UIButton*)btn
{
btn.titleLabel.textColor=[UIColor blueColor];
}
hope it will work for you.
use below code you will get your solution
UIButton *bt =[[UIButton alloc]initWithFrame:frame];
bt=[UIButton buttonWithType:UIButtonTypeCustom];
[bt setTitle:#"Custom Button" forState:UIControlStateNormal];
[bt addTarget:self action:#selector(userTappedOnLink:) forControlEvents:UIControlEventTouchUpInside];
[bt setBackgroundColor:[UIColor grayColor]];
[bt setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
[self.mainscrollview addSubview:bt];
[self.mainscrollview bringSubviewToFront:bt];
Use the below code:
[bt setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
Problem is you are set Title to titleLabel and you are changing textColor of buttonTitle color.
All the best !!!
check Button's Fram .. is it valid or not ??
and remove bt=[UIButton buttonWithType:UIButtonTypeCustom]; line from your code.
