Question

I know how to set the enable = YES/NO, a button created using a property and xib. However, how do you do the same thing to a programmatically created button from another method in the same class?

For example here is my button in the viewDidLoad:

UIButton *AllList = [UIButton buttonWithType:UIButtonTypeCustom];
AllList.frame = CGRectMake(40, 80, 107.f, 53.5f); //set frame for button

UIImage *buttonImageFull = [UIImage imageNamed:@"allModsBtn.png"];
[AllList setBackgroundImage:buttonImageFull forState:UIControlStateNormal];
[self.view addSubview:AllList];

// add targets and actions
[AllList addTarget:self action:@selector(getButtons:) forControlEvents:UIControlEventTouchUpInside];    
AllList.tag = 0;

I would like to set the enable of this button to YES or NO in another method.

Answer 1

@implementation {
     UIButton *myButton;
}

- (void)viewDidLoad {
    myButton = [UIButton buttonWithType:UIButtonTypeCustom];
    myButton.tag = 121;
    myButton.frame = CGRectMake(40, 80, 107.f, 53.5f); //set frame for button

    UIImage *buttonImageFull = [UIImage imageNamed:@"allModsBtn.png"];
    [myButton setBackgroundImage:buttonImageFull forState:UIControlStateNormal];
    [self.view addSubview:myButton];

   // add targets and actions
   [myButton addTarget:self action:@selector(getButtons:)       
   forControlEvents:UIControlEventTouchUpInside];    
   myButton.tag = 0;
}

- (void)someOtherMethod {

   myButton.enabled = YES;

OR

  //In this case you dont need to define uibutton to globaly

   UIButton *button = (UIButton*)[[self view] viewWithTag:121];
   [button setEnabled:YES];

}
