i am newbie in iOS Development i make an Application that contain ScrollView and i add an array images inside scrollview but it is not working.

I write a code for that 

for(int index=0; index < [self.imagesa count]; index++)
{
    NSDictionary *dict=[self.imagesa objectAtIndex:index];
    NSString *image=[dict valueForKey:@"link"];
    UIImageView *bigImage=[[UIImageView alloc]init];
    bigImage.bounds=CGRectMake(0, 0, self.zoomScroll.frame.size.width, self.zoomScroll.frame.size.height);
    bigImage.frame=CGRectMake(0, 0, self.zoomScroll.frame.size.width, self.zoomScroll.frame.size.height);
    [bigImage sd_setImageWithURL:[NSURL URLWithString:image] placeholderImage:[UIImage imageNamed:@"1.png"]];
    [self.objectarray insertObject:bigImage atIndex:index];
    CGSize scrollViewSize=CGSizeMake(self.zoomScroll.frame.size.width*[self.objectarray count], self.zoomScroll.frame.size.height);
    [self.zoomScroll setContentSize:scrollViewSize];
    [self.zoomScroll addSubview:bigImage];
    [self.zoomScroll addSubview:[self.objectarray objectAtIndex:index]];
}

it is add my all images in one imageview. not a one by one in Scrollview please give me solution for that

Here object array is NSMutableArray array and imagesa is also NSMutableArray and it is contain image URLlink.

See the X co-ordinate of your "bigImage.frame". Your adding images on same co-ordinates, one over the other. It should be...

bigImage.frame=CGRectMake(index * self.zoomScroll.frame.size.width, 0, self.zoomScroll.frame.size.width, self.zoomScroll.frame.size.height);

  • thnx bro but i want a space between images how it possible? – Ashish Gabani Nov 11 '14 at 05:41
  • #RoHaN also i add a UIPanGestureRecognizer and UIPinchGestureRecognizer to my bigimage then it is not working. – Ashish Gabani Nov 11 '14 at 05:48
  • For space just add some overhead to x co-ordinate. Something like 10.0f. "bigImage.frame=CGRectMake(index * self.zoomScroll.frame.size.width + 10.0f, 0, self.zoomScroll.frame.size.width, self.zoomScroll.frame.size.height);" – RoHaN Nov 11 '14 at 06:01
