I have an NSMutableArray with 3 UIButtons and Second NSMutableArray with 50 UIButtons. I want to take these 3 UIButtons Titles to Assign it Character by Character to each UIButton of SecondArray.but Each of these 50 UIButtons of Second Array already have single Character.My Basics purpose is that first of all i want to check the length of each uibutton title of my first Array,then assign it to index by index to UIButton in Second Array.(For Exp if my first Button have titles "stack",second "over" and Third "flow" no i want to Assign UIButtons of index 0-5 ,13-16,35-38 in Second Array) .My first Array that have 3 UIBttons .here is code.
NSMutableArray *buttons = [NSMutableArray arrayWithObjects:btn1, btn2, btn3, nil];
[btn1 setTitle:@"stack" forState:UIControlStateNormal];
[btn2 setTitle:@"over" forState:UIControlStateNormal];
[btn3 setTitle:@"flow" forState:UIControlStateNormal];
Here is my code.To create 50 UIButtons.
-(void)button:(id)sender {
saveBtn = [[NSMutableArray alloc] init];
arr=[[NSArray alloc]
initWithObjects:@"A",@"B",@"C",@"D",@"E",@"F",@"G",@"H",@"I",@"J",@"K",@"L",
@"M",@"N",@"O",@"P",@"Q",@"R",@"S",@"T",@"U",@"V",@"W",@"X",@"Y",@"Z",nil];
for (int i=0; i<50; i++) {
btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn.frame = CGRectMake(spacex, spacey, 30.0, 30.0);
int idx;
idx = arc4random()%[arr count];
NSString* titre = [arr objectAtIndex:idx];
[btn setTitle:titre forState:UIControlStateNormal];
spacex = spacex + 30;
[saveBtn addObject:btn];
[self.view addSubview:btn];
}
}
Any one guide me how can i assign my UIButton Titles to these UIButtons on Specific Index. Thanx

a = (NSString *)[[b1 titleLabel] text];
[storewords addObject:a];
NSLog(@"b=%@",a);
}
else if(i == 1)
{
}
else if(i == 2)
{
}
}
}
for (NSString *str in storewords) {
if (str==a) {
int j = 0;
int randn= (arc4random()%5)+1 ;
NSLog(@"n=%d",randn);
for (int i=randn; i<[a length]+randn; i++) {
NSLog(@"a=%@",a);
NSString *ichar = [NSString stringWithFormat:@"%c", [a characterAtIndex:j]];
UIButton* b = [saveBtn objectAtIndex:i];
NSLog(@"a=%@",ichar);
j++;
[b setTitle:ichar forState:UIControlStateNormal];
}
}
if (str==c) {
}
