Question

Im creating and adding a grid of buttons to my custom view keyboardView as follows:

int offset = 0;
for (int row = 0; row<4; row++){
    for (int col = 0; col<13;col++) {
        offset +=1;
        UIButton *aButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
        aButton.frame = CGRectMake(5+col*65+offset,5+row*65, 60, 60);
        [aButton setTitle:myarray[row][col] forState:UIControlStateNormal];
        [aButton addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];         

        [keyboardView addSubview: aButton];
    }
}

I need certain buttons to be of different sizes, like the return key or space bar. How can i get a reference to a particular button programmatically, later on in the same method? Is there an easier way than setting the tag and then calling [keyboardView viewWithTag:t]? Becauseint‘s are going to get confusing.

Thanks.

Answer 1

You could make instance variables like UIButton *spaceBar. if you reach the Button in the two for-Iretations which is thought to be the spacebar just do spacebar = aButton.
So you can later in the method just use this instance Variable which refers to the specified button. 😉
I hope it’s more or less understandable. ^^
