Hinzufügen mehrerer UIButton aus Array und screenboud

Question

Ich brauche dynamische Schaltfläche mit Array-Elementen erstellen. Auch Schaltfläche sind zeilenweise in ansteigender Reihenfolge wie

2 button 
3 button 
4 button 
5 button 

Mein Code:

- (void)viewDidLoad { 

    btn_array=[[NSMutableArray alloc]init]; 
    [btn_array addObject:@"Deepak Singh"]; 
    [btn_array addObject:@"Vikas Singh"]; 
    [btn_array addObject:@"Vipin Rawat"]; 
    [btn_array addObject:@"Deepak"]; 
    [btn_array addObject:@"Singh"]; 
    [btn_array addObject:@"Rawat"]; 
    [btn_array addObject:@"Vinita rawat"]; 
    [btn_array addObject:@"Vinod"]; 
    [btn_array addObject:@"OOP"]; 

    [self drawButtonsFromArray:btn_array]; 

     [super viewDidLoad]; 
    // Do any additional setup after loading the view, typically from a nib. 
} 



-(void)drawButtonsFromArray:(NSArray*)arr 

{ 
    UIScreen *mainScreen = [UIScreen mainScreen]; 


    int x=20 ,y=100; 

     for (int i=0; i<[arr count]; i++) 
     { 
      UIButton *btn=[[UIButton alloc]init]; 
      CGSize stringsize = [[arr objectAtIndex:i] sizeWithFont:[UIFont systemFontOfSize:14]]; 
      [btn setTitle:[arr objectAtIndex:i] forState:UIControlStateNormal]; 
      [btn setTitle:[arr objectAtIndex:i] forState:UIControlStateSelected]; 
      [btn setTitle:[arr objectAtIndex:i] forState:UIControlStateHighlighted]; 
      CALayer *btnLayer = [btn layer]; 
      [btnLayer setMasksToBounds:YES]; 
      [btnLayer setCornerRadius:10.0f]; 
      [btn setBackgroundColor:[UIColor redColor]]; 
      btn.titleLabel.adjustsFontSizeToFitWidth = YES; 


      [btn setFrame:CGRectMake(x,y,stringsize.width, 25)]; 

      int ww=x+btn.frame.size.width; 

      NSLog(@"X=====%d ",x); 

      NSLog(@"ww=====%d ",ww); 

      if (ww>=mainScreen.bounds.size.width) { 

      x=20; 
      y=y+35; 
       //[btn setFrame:CGRectMake(x,y,stringsize.width+15, 25)]; 

      } 
      else 
      { 

       x=x+btn.frame.size.width+5; 

      } 
      [self.view addSubview:btn]; 


     } 


}
