Creating UIButtons dynamically - Logic Error - iphone

Question

I have a NSMutableArray, and i have saving some string values in it. The size of the NSMutableArray could vary from 2-5 (Meaning it might have 2 -5 string values stored in it).
Depending on the count of the NSMutableArray i need to initialize UIBUttons and then set the value of the String stored init to the buttons title.
int numberOfButtonsToBeInitialize= [mutableArr count];// we are finding the number of buttons to be initialize and we assign it to a variable.
Now i need to create buttons (what ever the number returned by numberOfButtonsToBeInitialize)
How can i do this ?

Answer 1

for(int i=0;i<numberOfButtonsToBeInitialize;i++){
//init the button
UIButton *bout = [UIButton buttonWithType:UIButtonTypeRoundedRect];
//set the title
[bout setTitle:[mutableArr objectAtIndex:i] forState:UIControlStateNormal];
[bout addTarget:self action:#selector(event:) forControlEvents: UIControlEventTouchUpInside];
[self.view addSubview:bout ];
//then you can set the position of your button
[bout setFrame:CGRectMake(70,3, 40,40)];}

Answer 2

Try this:
NSMutableArray *myButtonsArray = [[NSMutableArray alloc] initWithCapacity:0];
UIButton *tmpButton;
for (NSString *bTitle in mutableArr)
{
tmpButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[tmpButton setTitle:bTitle forState:UIControlStateNormal];
// Any additional setup goes here
[myButtonsArray addObject:tmpButton];
}
Now you have an array with all the buttons. You can just iterate this array and add any button as a subview in your main view.

Answer 3

You need a for loop. For example:
float buttonWidth=50;
float margin=5;
for (int index=0; index<numberOfButtonsToBeInitialize;index++)
{
UIButton* button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
NSString* buttonTitle=[mutablearr objectAtIndex:index];
[button setTitle:buttonTitle forState:UIControlStateNormal];
[button setFrame:CGRectMake(0+(buttonWidth+margin)*index, 0, buttonWidth, 30)];
[button setTag:100+index];
[button addTarget:self action:#selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
}
In this case we layout buttons in a row(horizontally). Adjust to your own preferences
