Here is what its doing- note the space between navigation bar and the movingview:
You have to disable the automaticallyAdjustsScrollViewInsets in your view controller
[self setAutomaticallyAdjustsScrollViewInsets:NO];
or in Storyboard
Uncheck the option

Try this Delegate Method.This delegate will tell you that scrolling has finished.
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
Try this code, you use recongizer object view tag.

Add tap gesture action to the image and you can get the tag using [sender tag]
I have Few ImageView each of them have tag and I have an array of images. when user tap on image then I get image tag and take action on it.

I am trying to add the uiLabel on top of the uiImageVIew which is the background image. When it comes to adding the uiLabel on top of the uiImageView, the uilabel cannot be aded when testing and running. Would you please tell me the alternatives or precautions if doing so ?
The below is my code :
#implementation CoverViewController
- (void)viewDidLoad {
[super viewDidLoad];
_container = [[UIView alloc] initWithFrame:[self.view bounds]];
[self setTapDemo :[UIImage imageNamed:#"cover_1_d.png"] ] ;
}
- (void) setTapDemo: (UIImage *) cover {
_image = [UIImage imageNamed:#"shaded_region.png"];
_imageShaded = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
[_imageShaded setImage:_image];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
[imageView setImage: cover ];
_imageShaded.userInteractionEnabled = YES;
UITapGestureRecognizer *myGesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:#selector(touchesBegan:)];
myGesture.numberOfTapsRequired = 1;
myGesture.delegate=self;
[_imageShaded addGestureRecognizer:myGesture];
[_imageShaded setContentMode:UIViewContentModeScaleAspectFill];
NSString * text = #"Quad name:";
CGSize labelSize = CGSizeMake(60, CGFLOAT_MAX);
UILabel *fromLabel = [[UILabel alloc]initWithFrame:CGRectMake(91, 15, labelSize.width, labelSize.height)];
fromLabel.text = text;
fromLabel.numberOfLines = 1;
fromLabel.lineBreakMode = NSLineBreakByWordWrapping;
fromLabel.baselineAdjustment = UIBaselineAdjustmentAlignBaselines; // or UIBaselineAdjustmentAlignCenters, or UIBaselineAdjustmentNone
fromLabel.adjustsFontSizeToFitWidth = YES;
fromLabel.minimumScaleFactor = 10.0f/12.0f;
fromLabel.clipsToBounds = YES;
fromLabel.backgroundColor = [UIColor clearColor];

Check This

}
You are adding your UILabel more than once on different views. you should add it on a single view at a time;
//[_imageShaded addSubview:fromLabel]; // 1
//[imageView addSubview:fromLabel]; // 2
[_container addSubview:_imageShaded];
[_container addSubview:imageView];
//[_container addSubview:fromLabel]; //3
I need to add images in scroll view multiple times. Am created a scrollview but images not append correctly in that.
My code is here :
-(void)sampleScroll
{
int x = 10;
int y = 20;
mainScrollView = [[UIScrollView alloc] initWithFrame:self.view.frame];
mainScrollView.contentSize = CGSizeMake(50, (y + 95) * 5);
// further configure
[self.view addSubview: mainScrollView];
images = [[NSMutableArray alloc] initWithObjects:#"image0.jpg",#"image1.jpg",#"image2.jpg",#"image3.jpg", nil];
for(int i=0; i<[images count]; i++)
{
NSLog(#"%#",images);
UIScrollView *scrollview=[[UIScrollView alloc]initWithFrame:CGRectMake(x, y, 250, 150)];
scrollview.showsVerticalScrollIndicator=YES;
scrollview.scrollEnabled=YES;
scrollview.userInteractionEnabled=YES;
scrollview.backgroundColor = [UIColor whiteColor];
NSString *img = [images objectAtIndex:i];
NSLog(#"%#",img);
imageView.image = [UIImage imageNamed:#"image3.jpg"];
NSLog(#"%#",imageView.image);
scrollview.contentSize = CGSizeMake(1250,250);
[scrollview addSubview:imageView];
[mainScrollView addSubview:scrollview];
y=y+155;
//[self myscrollView];
}
}
Please give me a solution. Thanks in advance..

If you want to add Images horizontally (say 3 images), than you have to add scroll view with the width of 3*yourImageView.frame.size.width and than you can add those Image on (x=0,y=0),
(x = yourImageView.frame.size.width, y=0), and (x = 2*yourImageView.frame.size.width, y=0)
UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, yourImageView.frame.size.width, self.view.frame.size.height)];
scroll.pagingEnabled = YES;
NSInteger numberOfViews = 3;
imageView1.frame = CGrectMake(0,0,imageView1.frame.size.width,imageView1.frame.size.height);
imageView2.frame = CGrectMake(0,imageView1.frame.size.width,imageView2.frame.size.width,imageView2.frame.size.height)
imageView3.frame = CGrectMake(0,2*imageView1.frame.size.width,imageView3.frame.size.width,imageView3.frame.size.height)
[scroll addSubview:imageView1];
[scroll addSubview:imageView2];
[scroll addSubview:imageView3];
enable horizontal scrolling
I am trying to develop this app and Im have a really hard time. Im am trying to use a UISegmentedControl to load a set of UIScrollViews which act as image filters.
Aside from having huge issues with the UIScrollViews (which is why a new one is creed individually in each segment) for some reason, clicking on segment 1 loads all 6 UIScrollViews and only lets me scroll the first one. When I select the last segment only 1 UIScrollView is loaded...
I really don't know what Im doing wrong here so any suggestions would be great!
Thanks very much,
Lawrence

You missed the break statements. Switch needs a break statement at the end of each case statement. Otherwise it executes all the code after the first susccessful match, regardless of the case values. ie.
switch (soemthing) {
case 1: // do something
break;
case 2: // do something else
break;
default:
}
Works as you expect. If you drop the breaks, then case 1 will execute all the code below it.
