I have created a button. The title's color is black by default. But when I press it, the color changes to be a little blue and never changes back again, how does this happen? Can anyone tell me why? And I want the button's title remain black all the time. How can I do that? I have tried
[button setTitleColor:[UIColor darkTextColor] forState:UIControlStateHighlighted];
[button setTitleColor:[UIColor darkTextColor] forState:UIControlStateSelected];
But There is no effect. When I add this in my code, it seems the button's title always blue.
Code as follows.
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:CGRectMake(20, 360, 280, 44)];
[button setTitle:NSLocalizedString(@"Continue", @"Label: TextLabel in Continue button") forState:UIControlStateNormal];
button.titleLabel.font = [UIFont fontWithName:@"Helvetica-Bold" size:20.0f];
button.titleLabel.textColor = [UIColor darkTextColor];
button.titleLabel.shadowColor = [UIColor blackColor];
button.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin|UIViewAutoresizingFlexibleRightMargin|UIViewAutoresizingFlexibleBottomMargin|UIViewAutoresizingFlexibleWidth;
[self.view addSubview:button];
[button release];
Thanks everyone. I have sloved the problem. I think the root cause is
button.titleLabel.textColor = [UIColor darkTextColor];
When I remove this, and use
button setTitleColor:(UIColor) forState:(UIControlState);
The problem is solved!

You should initialize your button with UIButtonTypeCustom
instead of UIButtonTypeRoundedRect

watch out, system will ignore setTitleColor(_:for:) if button is not type custom.

As @null points out, by far the simplest way to do this is to set the button type in Interface Builder (or in code) to "Custom".
If you need to replicate this behavior with a standard button, override the setHighlighted
method to prevent the alpha channel of the titleLabel from adjusting too:
- (void)setHighlighted:(BOOL)highlighted
{
[super setHighlighted:highlighted];
self.titleLabel.alpha = 1.0;
}

There are a few comments pointing this out, but in order to have it as an actual answer:
Set the button type to Custom
in your storyboard or in code:
[UIButton buttonWithType:UIButtonTypeCustom];

you can use
[UIButton setTitleColor:forState:]
for all the states , then title color will remain same for all states.
[button setTitleColor:[UIColor redColor] forState:UIControlStateHighlighted];
[button setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
[button setTitleColor:[UIColor redColor] forState:UIControlStateSelected];
Note:To avoide type or paste above code three times you can use following code suggested by Will,
[button setTitleColor:[UIColor redColor] forState:(UIControlStateHighlighted | UIControlStateNormal | UIControlStateSelected)];

Using Interface Builder and either .XIB
or .storyboard
, select your UIButton
in IB:
View > Utilities > Show Attributes Inspector.
Select State Config (Default) to one of Highlighted, Selected or Disabled and change the Text Color attribute.

For something a little more reusable you might consider this, as it doesnt violate the DRY principle. Add this as a category on UIButton.
- (void)oka_setTitleColor:(UIColor *)color forStates:(NSArray *)states;
{
[states enumerateObjectsUsingBlock:^(NSNumber *state, NSUInteger idx, BOOL *stop) {
[self setTitleColor:color forState:[state integerValue]];
}];
}
example usage for your case:
[self oka_setTitleColor:[UIColor darkTextColor]
forStates:@[@(UIControlStateNormal), @(UIControlStateHighlighted), @(UIControlStateSelected)]];

I think mayuur is right. Have you tried another color instead of "darkTextColor" though? As far as I know "darkTextColor" is a system specific color that is used to write Text on light backgrounds. Maybe try blackColor if mayuurs suggestion doesn't work.
Edit: Try adding: [sender setHighlighted:NO];
into your IBAction which is called on button press. Does it solve it? I suggest this because from the [button release];
I guess you're still running an old version of the iOs SDK and there you don't have the option to disable the highlight of a button in an elegant way other than this.
Edit2: You're creating the button programmatically but I don't see you connecting it with an IBAction.
Add this below your [[UIButton alloc] init];
[button addTarget:self action:@selector(myIBAction) forControlEvents:UIControlEventTouchUpInside];
Then create an IBAction method like this:
- (IBAction)myIBAction:(UIButton *)sender; /* In Header File */
- (IBAction)myIBAction:(UIButton *)sender{ /* In Implementation File */
[sender setHighlighted:NO];
}
