Question

I have 3 different buttons, and I am using for loop to display it in my UIView. The problem is, there is only one button shown.

float yButton = 50.0;

for (int i = 0; i < 2; i++) {
    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    button.frame = CGRectMake(80.0, yButton + 70.0, 160.0, 40.0);
    [button addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchDown];
    [self.view addSubview:button];
    [button setTag:i];
}

Also, how do I set the button titles to A, B, and C (since there are only 3 buttons).

Answer 1

You give all of the buttons the same frame. You need to increment the y origin.

At the end of the loop, do this:

yButton += 50; // pick a value that meets your needs.

To set the titles, create an array with the three titles:

NSArray *titles = @[ @"A", @"B", @"C" ];

then in the loop:

[button setTitle:titles[i] forState:UIControlStateNormal];
