When I change the title of a UIButton it has this effect where the old title fades out and the new one fades in. Can I change the title without the animation?
[self.a setTitle:#"a" forState:UIControlStateNormal];
For system UIButton, using:
[self.a layoutIfNeeded];
For custom UIButton, using:
[UIView setAnimationsEnabled:NO];
[self.a setTitle:#"a" forState:UIControlStateNormal];
[UIView setAnimationsEnabled:YES];
There is two way to do this
1.System Button without animation
- (IBAction)actionChangeButtonTitle:(id)sender
{
[UIView setAnimationsEnabled:NO];
[buttonTitleChange setTitle:#"title" forState:UIControlStateNormal];
[UIView setAnimationsEnabled:YES];
[buttonTitleChange layoutIfNeeded]; //For System Buttons
}
2.Custom Button Without animation
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn addTarget:self
action:#selector(actionChangeButtonTitle:)forControlEvents:UIControlEventTouchUpInside];
[btn setTitle:#"Change Title" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[view addSubview:btn];
- (IBAction)actionChangeButtonTitle:(id)sender
{
[btn setTitle:#"title" forState:UIControlStateNormal];
}
Thank You-:)

Is there any way to make the navigation bar title clickable? I don't have any specific class for navigation bar. I control everything from ViewController. If there's a way, I would love to know. I have been searching it for quite a white but couldn't find a suitable answer.
Make button on Navigation bar
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self
action:#selector(btnclick:)
forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"Title" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
button.frame = CGRectMake(0, 0, self.view.frame.size.width, 64.0);
self.navigationItem.titleView =button;
-(void)btnclick:(id)sender
{ NSLog(#"button click");
}
You can try like this way
UIView *topView = [[UIView alloc]initWithFrame:CGRectZero];
UIButton * button = [[UIButton alloc]initWithFrame:CGRectZero];
[button addTarget:self action:#selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"Title here" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button sizeToFit];
[topView addSubview:button];
[topView sizeToFit];
self.navigationItem.titleView = topView;
-(void)buttonAction:(Id) sender
{
NSLog(#"button clicked");
}
I am using custom UIButtons, and what I want to do is make it so that when a user touches the button it dims, or turns a grayish color, like the regular button does.
I just want the text to temporarily change color temporally when the users lifts there figure it will be back to the regular color.
I have tried this code:
button.showsTouchWhenHighlighted = TRUE;
but that just makes a white circle around it which is not what I'm looking for.
Thanks for the help.
The easiest way I've come across is:
[myButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[myButton setTitleColor:[UIColor greenColor] forState:UIControlStateHighlighted];
Try changing alpha of title label on button click like this
- (IBAction)buttonClick:(id)sender {
UIButton *button = sender;
[UIView animateWithDuration:0.2 delay:0.0 options:UIViewAnimationOptionAllowUserInteraction|UIViewAnimationOptionCurveEaseInOut animations:^
{
[button.titleLabel setAlpha:0.5];
} completion:^(BOOL finished)
{
[button.titleLabel setAlpha:1];
}];
}
You can utilize the following UIControlEvents:
UIControlEventTouchDown
UIControlEventTouchUpInside
UIControlEventTouchUpOutside
Assign target-action methods to them appropriately like so:
//when touch initiated
[myButton addTarget:self
action:#selector(buttonTouchStartAct:)
forControlEvents:UIControlEventTouchDown];
//on touch released outside button bounds
[myButton addTarget:self
action:#selector(buttonTouchEndAct:)
forControlEvents:UIControlEventTouchUpOutside];
//on touch released while still inside button bounds (most commonly used)
[myButton addTarget:self
action:#selector(buttonAct:)
forControlEvents:UIControlEventTouchUpInside];
-(void)buttonTouchStartAct:(UIButton *)sender
{
[sender.titleLabel setTextColor:[UIColor redColor]];
}
-(void)buttonTouchEndAct:(UIButton *)sender
{
[sender.titleLabel setTextColor:[UIColor greenColor]];
}
-(void)buttonAct:(UIButton *)sender
{
//touch ended in this case too
[self buttonTouchEndAct:sender];
//...
//your main button logic
//...
}
//when touch initiated
[myButton addTarget:self
action:#selector(buttonTouchStartAct:)
forControlEvents:UIControlEventTouchDown];
//on touch released outside button bounds
[myButton addTarget:self
action:#selector(buttonTouchEndAct:)
forControlEvents:UIControlEventTouchUpOutside];
//on touch released while still inside button bounds (most commonly used)
[myButton addTarget:self
action:#selector(buttonAct:)
forControlEvents:UIControlEventTouchUpInside];
and then inside the method change the color of the button
i've programmatically created a button with an image for normalState.
But I want to set a new button image when the button is pressed (the new image should be displayed for the rest of the time). I tried something, but it only works during tapping. So the button shows its old image after tapping again.
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setBackgroundImage:[UIImage imageNamed:#"image1.png"] forState:UIControlStateNormal];
[button setBackgroundImage:[UIImage imageNamed:#"image2.png"] forState:UIControlStateHighlighted];
button.frame = CGRectMake(15.0f, 32.0f, 24.0f, 20.0f);
[cell addSubview:button];
Thanks for your help.
Try to use this it will helps you.
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setBackgroundImage:[UIImage imageNamed:#"image1.png"] forState:UIControlStateNormal];
[button setBackgroundImage:[UIImage imageNamed:#"image2png"] forState:UIControlStateHighlighted];
button.frame = CGRectMake(15.0f, 32.0f, 24.0f, 20.0f);
// ----------- Add this line in your code -------
[button addTarget:self action:#selector(btnPressed:) forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:button];
- (void)btnPressed:(UIButton *)sender
{
[sender setBackgroundImage:[UIImage imageNamed:#"image2.png"] forState:UIControlStateNormal];
}
You have to do the setting in the target of the button. Add the following code:
[button addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
and set the image in that method for UIControlStateNormal:
- (void)buttonTapped:(UIButton *)sender {
[button setBackgroundImage:[UIImage imageNamed:#"image2png"] forState:UIControlStateNormal];
}
I know I could do this:
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(x, y, width, height);
[button setTitle:text forState:UIControlStateNormal];
[button addTarget:self action:#selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
button.backgroundColor = [UIColor clearColor];
but that leaves a border around the button.
I could also do this:
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(x, y, width, height);
[button setTitle:text forState:UIControlStateNormal];
[button addTarget:self action:#selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
then put a UILabel behind the button.
Is there a way to accomplish this ^ without needing two objects?
UPDATE:
To clarify my question:
I want the have text, only text, that when pressed performs a method call. For reasons that are complicated to explain I need to do this by way of a button. So, how do I make the text of a button the only visible part of the button. No border. No background. Just text.
UIButton *btnLikeUserCount = [[[UIButton alloc] init] autorelease];
[btnLikeUserCount.titleLabel setFont:[UIFont boldSystemFontOfSize:12]];
btnLikeUserCount.frame = CGRectMake(posx,posy,width,height);
[btnLikeUserCount setTitle:text forState:UIControlStateNormal];
[btnLikeUserCount setTitleColor:[UIColor colorWithRed:50/255.0 green:79/255.0 blue:133/255.0 alpha:1.0] forState:UIControlStateNormal];
[btnLikeUserCount addTarget:self action:#selector(btnLikeUserCountClick:) forControlEvents:UIControlEventTouchUpInside];
no need to take label object.
I can't get what you want exactly but you might be missed [self.view addSubview:button] in your code. so you can not display button with text.
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(x, y, width, height);
[button setTitle:text forState:UIControlStateNormal];
[button addTarget:self action:#selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
Your second code is working fine. In the below image hello is a button.
My code is:
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(110, 100, 100, 50);
[button setTitle:#"Hello" forState:UIControlStateNormal];
[button addTarget:self action:#selector(buttonPressed) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
in this way u can do this
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(100, 400, 100, 50);
[button setTitle:#"Button text" forState:UIControlStateNormal];
[button addTarget:self action:#selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
[button.layer setBorderColor: [UIColor clearColor]];
[button.layer setBorderWidth: 0.0];
[self.view addSubview:button];
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.
