Add multiple UIImageview to UIScrollview programmatically
UIView *view = nil;
NSArray *subviews = [scrollView subviews];
CGFloat curXLoc = 0;
for (view in subviews)
{
if ([view isKindOfClass:[UIView class]] && view.tag > 0)
{
CGRect frame = view.frame;
frame.origin = CGPointMake(curXLoc, 0);
view.frame = frame;
curXLoc += (kScrollObjWidth);
}
}
I placed one Scrollview
, in this scroll, I placed 5 UIImageview
in the XIB file
I have one image and one button, whenever I clicked the button, the image must be loaded in everything UIImageview
inside UIScrollview
programmatically.
and also i used the following coding
for(UIImageView *addview in Scroll)
{
if([addview isKindOfClass:[UIImageView class]])
{
UIImageView *newImage = (UIImageView *)addview;
newImage.image = [UIImage imageNamed:@"EarP010.jpg"];
}
}

Use this
NSArray* objects = [[NSBundle mainBundle] loadNibNamed:@"your xib name" owner:nil options:nil];
UIView* mainView = [objects objectAtIndex:0];
for (UIView* view in [mainView subviews]) {
if([view isKindOfClass:[UIImageView class]])
{
UIImageView *iview = (UIImageView *)view;
iview.image = [UIImage imageNamed:@"your imagename.png"];
}
}

Try it,
NSMutableArray * imagesArray = [[NSMutableArray alloc]init];
for (int imageCount = 0; imageCount < (noOfImages);imageCount++)
{
[imagesArray addObject:[UIImage imageNamed:@"localImagePath%d.png",imageCount]];
}
UIScrollView * scrollview = [[UIScrollView alloc]initWithFrame:CGRectMake(0.0,0.0,480.0,960.0)];
scrollview.contentSize = CGSizeMake(scrollview.size.width * (noOfImages),scrollview.frame.size.height);
scrollview.pagingEnabled = YES;
CGFloat xPos = 0.0;
for (UIImage * image in imagesArray) {
@autoreleasepool {
UIImageView * imageview = [[UIImageView alloc]initWithImage:image];
imageview.frame = CGRectMake(xPos, 0.0,scrollview.frame.size.width ,self.scrollView.frame.size.height);
[scrollview addSubview:imageview];
xPos += scrollview.size.width;
}
}

You can add images to the while loop if you know how many images you need.
UIScrollView *sv = [UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
....
[self.view addSubView:sv];
int i = 0;
while(i < numberOfImages){
i = i + 200;
UIImageView *i = [UIImageView alloc] initWithFrame:CGRectMake(20, i, 200, 100)]
....
[sv addSubView:i];
i++;
}
This is one of the situations you could use. You will need to know the number of image views you want and what Y values are in those images. Most of this code is pseudocode and needs some completion.
