how to add text view and image view on different views - ios

Question

I have added view controllers according to my array count and set the content size of the horizontal scroll view.now i want some text to be displayed on each view.
for this i have taken a for loop but i'm not able to add text views over the views.
this is my code:
-(void)loadScrollView
{
scrollView.contentSize = CGSizeMake(0, scrollView.frame.size.height);
NSMutableArray *controllers = [[NSMutableArray alloc] init];
for (unsigned i = 0; i < [_arrUrlLinks count]; i++) {
[controllers addObject:[NSNull null]];
}
// MyViewController1 *controller;
self.viewControllers = controllers;
// self.viewControllers =_txtView;
count=1;
// a page is the width of the scroll view
scrollView.pagingEnabled = YES;
scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * [_arrUrlLinks count], scrollView.frame.size.height);
scrollView.showsHorizontalScrollIndicator =YES;
scrollView.showsVerticalScrollIndicator = NO;
scrollView.scrollsToTop = NO;
scrollView.delegate = self;
pageControl.numberOfPages = [_arrUrlLinks count];
pageControl.currentPage = 0;
}
- (void)loadScrollViewWithPage:(int)page {
if (page < 0) return;
if (page >= [_arrUrlLinks count])
return;
controller = [viewControllers objectAtIndex:page];
if ((NSNull *)controller == [NSNull null]) {
NSString *deviceType = [UIDevice currentDevice].model;
if([deviceType isEqualToString:#"iPhone"])
{
controller = [[MyViewController1 alloc] initWithNibName:#"MyViewController1" bundle:nil];
}
else{
controller = [[MyViewController1 alloc] initWithNibName:#"MyViewController1_ipad" bundle:nil];
}
[controller initWithPageNumber: page];
NSLog(#"loadscrollviewwithpage");
[viewControllers replaceObjectAtIndex:page withObject:controller];
}
// add the controller's view to the scroll view
if (nil == controller.view.superview) {
CGRect frame = scrollView.frame;
frame.origin.x = frame.size.width * page;
frame.origin.y = 0;
controller.view.frame = frame;
NSLog(#"111111%#",resultDicArray);
NSLog(#"0000000%#",body);
NSLog(#"header======.>>>>..%#",headerstr);
}
[scrollView addSubview:controller.view];
[self downLoadData:page];
}
- (void)unloadScrollViewWithPage:(int)page {
if (page < 0) return;
if (page >= [_arrUrlLinks count]) return;
controller = [viewControllers objectAtIndex:page];
if ((NSNull *)controller != [NSNull null]) {
if (nil != controller.view.superview)
[controller.view removeFromSuperview];
[viewControllers replaceObjectAtIndex:page withObject:[NSNull null]];
NSLog(#"Unloadscrollviewwithpage");
}
}
- (void)scrollViewDidScroll:(UIScrollView *)sender {
if (pageControlUsed) {
return;
}
CGFloat pageWidth = scrollView.frame.size.width;
int page = floor((scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1;
pageControl.currentPage = page;
[self unloadScrollViewWithPage:page - 2];
[self loadScrollViewWithPage:page - 1];
[self loadScrollViewWithPage:page];
[self loadScrollViewWithPage:page + 1];
[self unloadScrollViewWithPage:page + 2];
count=page+1;
// [self newCountTitleSet];
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self loadScrollView];
[self loadScrollViewWithPage:0];
[self loadScrollViewWithPage:1];
}
i have successfully added my controllers over the scroll view now how to add text view over the controllers.

Answer 1

Try this,
....
if (nil == controller.view.superview) {
.....
CGRect frame = scrollView.frame;
frame.origin.x = frame.size.width * page;
frame.origin.y = 0;
controller.view.frame = frame;
//Add textview as subview to controller
UITextView *textView = [[UITextView alloc] init];
textView.text = #"hello";
textView.frame = //set frame here
//set tag to textView if needed
[controller.view addSubView:textView];
[scrollView addSubview:controller.view];
NSLog(#"loadscrollviewwithpage................>>>>>>>>>>>>");
}
....

For example you want to 10 diffrent images or textview you could use this logic:
- (void)viewDidLoad {
[super viewDidLoad];
UIScrollView *scr=[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
scr.tag = 1;
scr.autoresizingMask=UIViewAutoresizingNone;
[self.view addSubview:scr];
[self setupScrollView:scr];
UIPageControl *pgCtr = [[UIPageControl alloc] initWithFrame:CGRectMake(0, 264, 480, 36)];
[pgCtr setTag:12];
pgCtr.numberOfPages=10;
pgCtr.autoresizingMask=UIViewAutoresizingNone;
[self.view addSubview:pgCtr];
}
- (void)setupScrollView:(UIScrollView*)scrMain {
// we have 10 images here.
// we will add all images into a scrollView & set the appropriate size.
for (int i=1; i<10; i++) {
// create image
UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:#"sti%02i.jpeg",i]];
// create imageView
UIImageView *imgV = [[UIImageView alloc] initWithFrame:CGRectMake((i-1)*scrMain.frame.size.width, 0, scrMain.frame.size.width, scrMain.frame.size.height)];
// set scale to fill
imgV.contentMode=UIViewContentModeScaleToFill;
// set image
[imgV setImage:image];
// apply tag to access in future
imgV.tag=i+1;
// add to scrollView
[scrMain addSubview:imgV];
UITextView*txtview =[[UITextView alloc]initWithFrame:CGRectMake(10,50,200,200)];
[txtview setDelegate:self];
[txtview setReturnKeyType:UIReturnKeyDone];
[txtview setTag:1];
[txtview setText:[yourArray ObjectAtIndex:i]];
[txtview setCornerRadius:5];
[scrMain addSubview:txtview];
}
// set the content size to 10 image width
[scrMain setContentSize:CGSizeMake(scrMain.frame.size.width*10, scrMain.frame.size.height)];
}
