I am trying to populate an iCarousel with a parse (parse.com, pfoject) object without success.
I can't find any example of how to do it, so it why i am asking here...
- (void)viewDidLoad
{
[super viewDidLoad];
_items = [NSMutableArray array];
PFQuery *query = [PFQuery queryWithClassName:@"testUser"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
// The find succeeded. The first 100 objects are available in objects
[_items addObjectsFromArray:objects];
} else {
// Log details of the failure
NSLog(@"Error: %@ %@", error, [error userInfo]);
}
}];
//configure carousel
_carousel.type = iCarouselTypeRotary;
//_carousel.viewpointOffset = CGSizeMake(0.0f, 100.0f);
[_carousel setContentOffset:CGSizeMake(0.0f, -60.0f)];
}
And at viewForItemAtIndex:
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
//create new view if no view is available for recycling
if (view == nil)
{
view = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 300.0f, 300.0f)];
}
PFObject *eachObject = [_items objectAtIndex:index];
PFFile *theImage = [eachObject objectForKey:@"image"];
NSData *imageData = [theImage getData];
UIImage *image = [UIImage imageWithData:imageData];
((UIImageView *)view).image = image;
view.contentMode = UIViewContentModeCenter;
return view;
}
Please, any help? :-(
In viewDidLoad, After the
[_items addObjectsFromArray:objects];
Put
[_carousel reloadData];
Otherwise the carousel won't be updated after the items have been added to the array, so you'll still be looking at an empty carousel.
