Adding independent Progress VIew for indicate download in iCarousel - ios

Good afternoon. I use in my application iCarousel . At the moment I can not make Progress View each item carousel. The problem is that when I click on the "Download button" Progress View have added an item first . He appears fine and works , but also appears in another 2 item from another view, where it should not be . After that, when I again click the " download button " Progress View begin to be confused with each other. Please tell me exactly what I 'm doing wrong and how I act of intercourse ? I'm new to objective-c.
P.S To download the data I use AFNetworking.

To Wain:
Sorry but I can not understand your question. I pass the URL from the dictionary in the method of downloading data. In Method iCarousel I assign Progress View tag = 7 then I add a condition to hide like this:
if (([fileManager fileExistsAtPath:[NSString stringWithFormat:#"%#/%#_mag.pdf.tmp",docDir,[myDic objectForKey:#"title"]]] == YES) && (index == [self.carousel currentItemIndex]))
{
[[[view viewWithTag:7] setHidden:NO];
[[[view viewWithTag:7] setHidden:NO];
}
else
{
[[[view viewWithTag:7] setHidden:YES];
[[[view viewWithTag:7] setHidden:YES];
}

Don't create and add the progress view in pressDownload:. Instead, create it when the view is created but set it to hidden. Then when you need it just un-hide it. When you reuse a view be sure to set the appropriate value based on whether you are downloading the item at that index.

UIscrollView To scroll images horizontally and show images from the image clicked

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.

What does MVC Even mean in the context of IOS?

I used to have a massive packed 8k+ line FeedViewController and anytime I wanted to change anything involving the look of statuses I had to change no less than a dozen viewcontrllers so I decided to try to refactor to follow a MVC type standard. I put most of the functionality in the tableviewcells so that I could just change the cell class instead of 12 files, now im hearing "you should keep your VIEWS dumb.....is this really so wrong?

Ok. I've tried to merge all comments to a suitable answer.
When you want to stick to the MVC pattern you should keep your views as dumb as possible (regarding the coupling of view- and business-related components). In the best case they should not contain any business logic.
That implies that they also should not know anything about business objects (the model). As long as your statusObject in self.StatusLabel.text = self.statusObject.message; is anything else than a Data Transfer Object it is not a good idea to let the cells retrieve their values on their own - because then these cells would need to have knowledge about your model structure.
Usually each view does have its own view controller but - of course - you're allowed to compose your view controllers with functionality they need.
For example: if some view controllers need data you could introduce a separate (view related) component which will provide that data (e.g. by creating and returning cells). This component would be fed with your model data (or Data Transfer Objects) and would return a structure which could be used by all view controllers who need those information.

How to add textfield in scrollview in ios?

I am making an app in which i am selecting photos from gallery and I want that on every picture or video one textfield will appear so that if i want to describe about that pic or video.
here is the code of display the photos but not showing the textfield on above the every pic in scrollview.

I don't understand your code lines. The problem should be there.
Why are you doing below things?
[imageScroll addSubview:textfield1];
for(UIView *v in [imageScroll subviews]){
[v removeFromSuperview];
}
In first line you are adding textfield to your scrollview and then you are using for loop to remove all subviews. It will remove your textfield from scrollview as well. You should not do this if you want to show textfield to user.
Please try by commenting the for loop. Hope it will work for you.
//Edit begins over here.
I think you should use UICollectionView instead of UIScrollView. In each and every cells of collectionview, you can show image and textfileds. It will be easy for you and also it will look better.
Thanks
Use NSMutableArray store UITextField value in it and call it with image array with function on the same button.
NSMutableArray *arr = [NSMutablearray....];
for (UIView *subV in self.view.subviews){
if([subV isKindOfClass:[UITextField class]])
{
//store it in a NSDictionary, so later can still know which
//textField your text belongs,
NSDictionary *tempDic = [NSDictionary dictionaryWithObjectAndKey:subV.txt
,subV.tag,/*or subVw.placeholder*/,nil];
[arr addObject:tempDic];
}

How can I implement scroll view to horizontally scroll the view pages loaded from a NSDictionary. Presently i am using swipegesture but that is little slow.

Have you tried as like below methods,
UIScrollView * _scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0.0, 10.0, 320.0, 280.0)];
_scrollView.backgroundColor = [UIColor clearColor];
_scrollView.pagingEnabled = YES;
_scrollView.showsHorizontalScrollIndicator = NO;
_scrollView.showsVerticalScrollIndicator = NO;
_scrollView.scrollsToTop = NO;
_scrollView.delegate = self;
[self addSubview:_scrollView];
float width = 0.0;
for (int i = 0; i < pageCount; i++)
{
UIView * yourView = [[UIView alloc] initWithFrame:CGRectMake((i * 320.0) + 20.0, 0.0, 280.0, 280.0);
[_scrollView addSubview:yourView];
width = yourView.frame.size.width + yourView.frame.origin.x + 20.0;
}
[_scrollView setContentSize:CGSizeMake(width, _scrollView.frame.size.height)];
Look at UIScrollView. To be honest this question makes it look like you've done very little research into the problem though. Can you tell us a bit more about what you currently have and what you've done so far?
UIScrollView Scroll depends on the ContentSize. So you have to set the ContentSize.
For Horizinatal Scrolling
[scroll setContentSize:CGSizeMake(1500, scroll.frame.size.height)];
