NSMutableArray * val;
val = [[NSMutableArray alloc] initWithCapacity:15];

/*int outlineWidth = barOutlineWidth;
int outlineHalfWidth = (outlineWidth > 1) ? outlineWidth * 0.5f : 0;
 */
for ( Bar * obj in values )
{  
  // calcualte the bar size
  float value  = [obj value];
  float scale  = ( value / maxValue );

  // shift the bar to the top or bottom of the render line
  int pointY   = lineHeight + ( (lineWidth * 0.5f) * ( ( value >= 0.0f ) ? -1 : 1 ) );
  int barHeight = height * scale;
  NSLog(@"%d", barHeight);   
  CGRect barRect = CGRectMake(pointX, pointY, width, -barHeight);
  [val addObject:[NSNumber numberWithInt:barHeight]];
                     NSLog(@"%d", val);

I want to add the barheight (int) into array val. Is this possible? while running the code,

2010-09-16 13:21:53.812 BarGraphSample[3168:20b] 69398112
2010-09-16 13:21:53.813 BarGraphSample[3168:20b] 156
2010-09-16 13:21:53.814 BarGraphSample[3168:20b] 69398112

this is the output.

Here the actual barheights are 78,235,156, while printing the array val.

Im getting like values like "69398112"

What should I do?

This is a simple way: @(yourInt)

int value = 5;
NSMutableArray * anArray  = [[NSMutableArray alloc] init];
[anArray addObject: @(value)];
