Вы можете сделать что-то вроде:
int i=0;
UIButton *customButton=[UIButton buttonWithType:UIButtonTypeRoundedRect];
//Set the height of your button, that will depend on how much text you will be putting
//inside
[customButton setFrame:CGRectMake(3,40,315,130)];
for(i=0; i<7; i++){
//Their position will change depending on which label you are adding
UILabel *leftLabel=[[UILabel alloc] initWithFrame:CGRectMake(5, 5+(17*i), 150, 12)];
UILabel *rightLabel=[[UILabel alloc] initWithFrame:CGRectMake(160, 5+(17*i), 150, 12)];
//Set the text for each label
[leftLabel setText:[NSString stringWithFormat:@"Left %d",i+1]];
[rightLabel setText:[NSString stringWithFormat:@"Right %d",i+1]];
//Set the backgroudn as clear to be able to see the background of your button
[leftLabel setBackgroundColor:[UIColor clearColor]];
[rightLabel setBackgroundColor:[UIColor clearColor]];
//Add those labels
[customButton addSubview:leftLabel];
[customButton addSubview:rightLabel];
//Do your memory management
[leftLabel release];
[rightLabel release];
}
