I am trying to show no. of images in different image view. if i have 3 image then i want show in 3 diff. UIImageView in my View. Here is my code that only shows one image. What have i missed here?
NSArray * _thumbnails = _claimReport.photos.allObjects;
if (_thumbnails.count >0)
{
NSMutableArray *imageViews = [[NSMutableArray alloc] init];
for (int i =1; i<_thumbnails.count; i++)
{
UIImageView *newImageViews = [[UIImageView alloc]initWithFrame:CGRectMake(40, 1700*i+20, 670, 700)];
LAPhoto *photo = [_thumbnails objectAtIndex:i];
[newImageViews setImage:[UIImage imageWithData:photo.photo]];
NSLog(#" newImageViews %# ",newImageViews);
[imageViews addObject:newImageViews];
[self.formView addSubview:newImageViews];
}
NSLog(#"Count %d" , imageViews.count);
}
You can add the images in a scroll view:
self.scrollView = [[UIScrollView alloc]initWithFrame:self.view.bounds];
[self.formView addSubview:self.scrollView];
NSArray * _thumbnails = _claimReport.photos.allObjects;
if (_thumbnails.count >0)
{
NSMutableArray *imageViews = [[NSMutableArray alloc] init];
for (int i =0; i<_thumbnails.count; i++)
{
UIImageView *newImageViews = [[UIImageView alloc]initWithFrame:CGRectMake(40, 800*i+20, 670, 700)];
LAPhoto *photo = [_thumbnails objectAtIndex:i];
[newImageViews setImage:[UIImage imageWithData:photo.photo]];
NSLog(#" newImageViews %# ",newImageViews);
[imageViews addObject:newImageViews];
self.scrollView.contentSize = CGSizeMake(670, 800 *i + 800);
[self.scrollView addSubview:newImageViews];
}
NSLog(#"Count %d" , imageViews.count);
}

I have four images on a viewcontroller.On the click of those images a newViewController i.e. LargeImageViewController opens. On the LargeImageViewController there is ScrollView which does horizontal scrolling. On click of every button the images on LargeImageViewController starts from image1 ,then shows image2,then image 3,then image 4.
I want that if image 2 is clicked then the images on LargeImageViewController should start image2,then image 3,then image 4.....but when it goes to previous image then it should show image 4,image3,image 2 and image1 also.
How this can be achieved??
Code that I am using are as follows:
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
// int pageCount=4;
NSArray *imgArray = [self.tripDetails valueForKey:#"Flightimageurl"];
width = [UIScreen mainScreen].bounds.size.width;
height = [UIScreen mainScreen].bounds.size.height;
_scroller = [[UIScrollView alloc]initWithFrame:
CGRectMake(0,64,width,height)];
_scroller.contentSize=CGSizeMake([imgArray count]*_scroller.bounds.size.width,_scroller.bounds.size.height);
CGRect ViewSize=_scroller.bounds;
for(int i=0;i<[imgArray count];i++)
{
UIImageView *imgView1=[[UIImageView alloc]initWithFrame:ViewSize];
NSString *ImageURL = [imgArray objectAtIndex:i];
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:ImageURL]];
imgView1.image=[UIImage imageWithData:imageData];
[_scroller addSubview:imgView1];
[self.view addSubview:_scroller];
ViewSize =CGRectOffset(ViewSize,_scroller.bounds.size.width,0);
}
}
Kindly help with suggesting the changes.

I have four images on a Viewcontroller A .On the click of those images Viewcontroller B having UIScrollView presents that has image view and it shows all those four imgaes....Image1 ,image 2,image 3,image 4.

Does anyone know why is appearing white part? My View is already gray, but gets two white pieces
whites: Arrow and final Popover!
[UPDATE]
this is the code that calls the popover and makes the arrow points to the button that was clicked!
- (void) buttonFilter {
if (viewFilter == #"Artistas") {
content = [self.storyboard instantiateViewControllerWithIdentifier:#"TipoArtistaViewController"]; // MUDAR PARA O NOVO FILTRO DE ARTISTAS
} else if (viewFilter == #"Músicas") {
content = [self.storyboard instantiateViewControllerWithIdentifier:#"CategoriaViewController"];
}
[self callFilter:btnFilter Filter:content];
}
- (void)callFilter:(id)sender Filter:(UIViewController *) content{
self.currentPop = popoverController;
popoverController = [[WYPopoverController alloc] initWithContentViewController:content];
UIButton * bt = (UIButton * )sender;
UIView *view = [bt valueForKey:#"view"];
popoverController.popoverContentSize = CGSizeMake(320, 180);
popoverController.delegate = self;
[popoverController presentPopoverFromRect:view.bounds inView:view permittedArrowDirections:WYPopoverArrowDirectionAny animated:YES];
}
the next is where to mount the session:
//extend and collpase
- (void)setupViewController {
categoriaBD = [categoriaDAO selectCategoria];
self.data = [[NSMutableArray alloc] init];
for (int i = 0; i < [categoriaBD count]; i++)
{
NSMutableDictionary * teste = [categoriaBD objectForKey:[NSString stringWithFormat:#"%i", i]];
ID = [[teste objectForKey:#"1"] integerValue];
subcategoriaBD = [categoriaDAO selectSubCategoriaByCategoriaID:ID];
NSMutableArray* section = [[NSMutableArray alloc] init];
for (int j = 0; j < [subcategoriaBD count]; j++)
{
NSMutableDictionary * subCat = [subcategoriaBD objectForKey:[NSString stringWithFormat:#"%i", j]];
[section addObject:[NSString stringWithFormat:[subCat objectForKey:#"1"]]];
}
[self.data addObject:section];
}
self.headers = [[NSMutableArray alloc] init];
for (int i = 0; i < [categoriaBD count]; i++)
{
NSString *inStr = [NSString stringWithFormat: #"%i", (int)i];
nomeCategoria = [categoriaBD objectForKey:inStr];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(5, 5, 310, 40)];
[label setText:[nomeCategoria objectForKey:#"2"]];
UIView* header = [[UIView alloc] init];
[header setBackgroundColor:[UIColor colorWithRed:(226/255.0) green:(226/255.0) blue:(226/255.0) alpha:1]];
[header addSubview:label];
[self.headers addObject:header];
}
}
You can to create a custom UIPopoverBackgroundView subclass that sets the properties of the arrow you want.
popoverController.popoverBackgroundViewClass = [MyPopoverBackgroundView class];
I would like to know based on my code, how can i add fade in fade out effect between each images in my NSArray. As i am using these images as background. Changing background without fade in and out looks horrible.
Here is my code.
- (void)viewDidLoad
{
[super viewDidLoad];
NSArray *imageNames = #[#"1.jpg", #"2.png", #"3.png", #"4.png",
#"5.png"];
NSMutableArray *images = [[NSMutableArray alloc] init];
for (int i = 0; i < imageNames.count; i++) {
[images addObject:[UIImage imageNamed:[imageNames objectAtIndex:i]]];
}
// Normal Animation
UIImageView *animationImageView = [[UIImageView alloc] initWithFrame:self.view.bounds];
animationImageView.animationImages = images;
animationImageView.animationDuration = 9;
[self.background addSubview:animationImageView];
[animationImageView startAnimating];}
I have a problem with changing images in the scrollview, the scrollview problem is that depending on the action that makes me have to change the image that contains other, as I do not change the picture or the array of images, I need help, thanks
- (void)viewDidLoad
{
[super viewDidLoad];
NSMutableArray *imgNames = [[NSMutableArray alloc] initWithObjects:#"cooper.png", #"cabrio.png",#"country.png", nil];
NSMutableArray *imgArray = [[NSMutableArray alloc] init];
UIImageView *tempImageView;
for(NSString *name in imgNames) {
tempImageView = [[UIImageView alloc] init];
tempImageView.contentMode = UIViewContentModeScaleAspectFit;
tempImageView.image = [UIImage imageNamed:name];
[imgArray addObject:tempImageView];
}
CGSize pageSize = scrollView.frame.size;
NSUInteger page = 0;
for(UIView *view in imgArray) {
[scrollView addSubview:view];
view.frame = CGRectMake(pageSize.width * page++ + 10, 0, pageSize.width - 20, pageSize.height);
}
scrollView.contentSize = CGSizeMake(pageSize.width * [imgArray count], pageSize.height);
}
- (IBAction)btnAction:(id)sender {
NSMutableArray *imgNames = [[NSMutableArray alloc] initWithObjects:#"hello.png", #"bye.png",#"trues.png", nil];
NSMutableArray *imgArray = [[NSMutableArray alloc] init];
UIImageView *tempImageView;
for(NSString *name in imgNames) {
tempImageView = [[UIImageView alloc] init];
tempImageView.contentMode = UIViewContentModeScaleAspectFit;
tempImageView.image = [UIImage imageNamed:name];
[imgArray addObject:tempImageView];
}
CGSize pageSize = scrollView.frame.size;
NSUInteger page = 0;
for(UIView *view in imgArray) {
[scrollView addSubview:view];
view.frame = CGRectMake(pageSize.width * page++ + 10, 0, pageSize.width - 20, pageSize.height);
}
scrollView.contentSize = CGSizeMake(pageSize.width * [imgArray count], pageSize.height);
}
}
You can directly set the image alone if UIImageView is already allocated in viewDidLoad like,
for(UIImageView *view in imgArray) {
view.image = [UIImage imageNamed:[imgNames objectAtIndex:[imgArray indexOfObject:view]]]
}
