To change the custom button title use this:

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(82,203,129,45);

[button setTitle:@"btnTitle" forState:UIControlStateNormal];
[button addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];

[self.view addSubview:button];
[self.view bringSubviewToFront:button];

declare your button and make property of your button in .h file

UIButton *btnl;

@property(nonatomic,retain) IBOutlet UIButton *btnl;

and make connection from IB.

Now in .m file,

use this delegate method of you picker

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
   btn.text=[yourArrayOfPickerContent objectAtIndex:row];
}

This way you can code about UIButton and can set the title to it.

UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];                               
[btn setFrame:CGRectMake(0.0f, 4.0f, 90.0f, 20.0f)];
[btn setBackgroundColor:[UIColor clearColor]];                              
UIImage *backgroundView = [UIImage imageNamed:@"btn.png"];
[btn setBackgroundImage:backgroundView forState:UIControlStateNormal];
[btn setTitle:@"buttonName" forState:UIControlStateNormal];
[btn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];

To change button title,

  button.titleLabel.text=@"String";

You should Code in the pickerView delegate

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component

first you need to create a pointer of type UIButton as IBOutlet in your view controller and than connect that button to the one in IB.

when you want to change the name of title just do

button.titleLabel.text = [NSString stringWithString:yourString];

You should be able to change the title of a UIButton by calling setTitle. Just remember to set it for all the states of the IUIButton. Here is an example:

[button setTitle:@"Normal Title" forState:UIControlStateNormal];
[button setTitle:@"Highlighted Title" forState:UIControlStateHighlighted];
