iCarousel doesn't show my images objective C - ios

Question

i want to display multiple images in a view controller using iCarousel.
i list all my images in NSMutableArray foto,
and then i called the array foto in iCarousel method viewForItemAtIndex.
i've followed some tutorial but still doesn't work.
please help me.
here's my .m code
#import "TestController.h"
#interface TestController () <UIActionSheetDelegate>
#property (nonatomic, retain) NSMutableArray *foto;
#end
#implementation TestController
#synthesize carousel;
#synthesize foto;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
foto = [NSArray arrayWithObjects:
[UIImage imageNamed:#"Seleb1.jpg"],
[UIImage imageNamed:#"Seleb2.jpg"],
[UIImage imageNamed:#"Seleb3.jpg"],
nil];
}
return self;
}
- (void)dealloc
{
carousel.delegate = nil;
carousel.dataSource = nil;
}
- (void)viewDidLoad
{
[super viewDidLoad];
carousel.type = iCarouselTypeCoverFlow2;
}
- (void)viewDidUnload
{
[super viewDidUnload];
self.carousel = nil;
}
#pragma mark -
#pragma mark iCarousel methods
- (NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel
{
return [foto count];
}
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[foto objectAtIndex:index]]];
return view;
}
#end
can someone help me ?
what is wrong with my code ?

Answer 1

change this line
view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[foto objectAtIndex:index]]];
to
Reason : you have already defined your array as [UIImage imageNamed:#"Seleb1.jpg"] , so in here you need call directly like
view = [[UIImageView alloc] initWithImage:[foto objectAtIndex:index]];
Choice-2
create a array like
foto = [NSArray arrayWithObjects:
#"Seleb1.jpg",
#"Seleb2.jpg",
#"Seleb3.jpg",
nil];
and call like
view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[foto objectAtIndex:index]]];
if you need
use this
- (void)viewDidLoad
{
[super viewDidLoad];
carousel.type = iCarouselTypeCoverFlow2;
[carousel reloadData];
}
Update answer
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view {
view = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200.0f, 200.0f)]; // set the frame for your Image
UIImage *image = [UIImage imageNamed:[foto objectAtIndex:index]];
((UIImageView *)view).image = image;
return view;
}

#TomKnapen : where should i set it ? if it's on the story board, i've
set it already. in the TestController.h, i've set it too here's my
code in .h : TestController : UIViewController – Shasapo
I'm not sure about how you are setting it in storyboard, but in code, you are not setting the delegate. This line doesn't set the delegate TestController : UIViewController <iCarouselDataSource,iCarouselDelegate>, what it does is it makes you controller, which is TestController in this case, comply to the iCarouselDelegate protocol. What you have to do is explicitly set the delegate and datasource in viewDidLoad,for example, i.e.
carousel.delegate = self;
carousel.datasource = self;
2 - try debugging those delegate methods first. Start with nimberOfItems method, check if foto array isnt nil. Then in viewForItem method check if the image that you return isn't nil.
Because you are using storyboard, your initWithNibName method not getting called, that is why you foto array not getting initialized, I assume. In my opinion your numberofitems method returns 0. Try to put breakpoint int this method and see, or just add a NSLog statement and check if foto array isnt nil
3 - You are not adding iCarousel view to your view.
I have used this framework in the past, so I decided to include a snippet of the code I implemented
#pragma mark -
#pragma mark iCarousel methods
- (void)iCarouselSetup {
self.view.backgroundColor = kAppColor;
self.carousel = [[iCarousel alloc] initWithFrame:CGRectMake(0, calendarBar.bottom + 10, self.view.width, self.view.height)];
[self.view addSubview:self.carousel];
self.carousel.delegate = self;
self.carousel.dataSource = self;
self.carousel.type = iCarouselTypeCoverFlow;
self.carousel.scrollEnabled = NO;
[self.carousel scrollToItemAtIndex:2 animated:NO];
self.currentProjectsTableview = (UITableView*)[self.carousel currentItemView]; }
- (NSInteger)numberOfItemsInCarousel:(iCarousel *)carousel {
return 5; }
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSInteger)index reusingView:(UIView *)view {
self.projectsTableview = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 0, 0) style:UITableViewStylePlain];
self.projectsTableview.x = 0;
self.projectsTableview.y = calendarBar.bottom;
self.projectsTableview.width = [ASize screenWidth];
self.projectsTableview.height = [ASize screenHeight] - 180;
self.projectsTableview.contentInset = UIEdgeInsetsMake(0, 0, 100, 0);
self.projectsTableview.backgroundColor = [UIColor fromRGB:0xF8F8F8];
self.projectsTableview.separatorStyle = UITableViewCellSeparatorStyleNone;
self.projectsTableview.dataSource = self;
self.projectsTableview.delegate = self;
self.projectsTableview.tag = tableTag++;
return self.projectsTableview; }
- (void)carousel:(iCarousel *)carousel didSelectItemAtIndex:(NSInteger)index {
self.carousel.scrollEnabled = NO;
[AppDelegate getDelegate].deckController.panningMode = IIViewDeckFullViewPanning;
[UIView animateWithDuration:0.3 animations:^{
for (int i = 0; i < self.carousel.numberOfItems; i++)
{
[self.carousel itemViewAtIndex:i].transform = CGAffineTransformMakeScale( 1.1f, 1.1f);
}
}completion:^(BOOL finished) {
[UIView animateWithDuration:0.2 animations:^{
for (int i = 0; i < self.carousel.numberOfItems; i++)
{
[self.carousel itemViewAtIndex:i].transform = CGAffineTransformMakeScale( 1.0f, 1.0f);
[self.carousel itemViewAtIndex:i].userInteractionEnabled = YES;
}
} ];
tableMinimized = NO;
}];
self.currentProjectsTableview = (UITableView*)[carousel itemViewAtIndex:index]; }
- (void)carouselDidEndScrollingAnimation:(iCarousel *)carousel {
[navButton setTitle:self.projectDates[self.carousel.currentItemIndex] forState:UIControlStateNormal]; }

i fix my code by combining all your answer, thankyou so much. here's my new code :
#import "TestController.h"
#interface TestController ()
#property (nonatomic, retain) NSArray *foto;
#end
#implementation TestController
#synthesize carousel;
#synthesize foto;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)dealloc
{
carousel.delegate = nil;
carousel.dataSource = nil;
}
- (void)viewDidLoad
{
carousel.delegate = self;
carousel.dataSource = self;
foto = [NSArray arrayWithObjects:
#"Seleb1.jpg",
#"Seleb2.jpg",
#"Seleb3.jpg",
nil];
[super viewDidLoad];
carousel.type = iCarouselTypeCoverFlow2;
[carousel reloadData];
}
- (void)viewDidUnload
{
[super viewDidUnload];
self.carousel = nil;
}
#pragma mark -
#pragma mark iCarousel methods
- (NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel
{
NSLog(#"%lu",(unsigned long)foto.count);
return [foto count];
}
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view {
view = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200.0f, 200.0f)]; // set the frame for your Image
UIImage *image = [UIImage imageNamed:[foto objectAtIndex:index]];
((UIImageView *)view).image = image;
return view;
}
- (CGFloat)carousel:(iCarousel *)carousel valueForOption:(iCarouselOption)option withDefault:(CGFloat)value
{
//customize carousel display
return value+0.1;
}
#end
Thank you so much for all your answer, i really appreciate it :)
