So I am trying to open a link with a button using the query from Parse. So the query works since the image and heading do come up. Also the key "Link" do load since the NSLog shows them. Its just that every time the view loads, the first link in the list is automatically opened. I am just wondering why. I want it to load it when the button is pressed and not when the view is loaded. If any questions, I will try to answer them to clarify the problem. Thanks in advanced!

linkButton = [[UIButton alloc] initWithFrame:userImage.frame];
[linkButton addTarget:self action:[[UIApplication sharedApplication]openURL:url] forControlEvents:UIControlEventTouchUpInside];

Let's try:

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.

Just updated to iOS 8.0 this morning. I have a piece of code which created some labels and displays them on the scree next to some images. It was working fine before the update. Now the label and the image is not displaying. Can some one please help as I have tried everything I can think of and nothing has solved my issue and couldn't find anyone else with a similar issue. Code attached below.
UIView *labelView = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, kCategoryLabelHieght)];
labelView.backgroundColor = [self colorWithHexString:#"2D2D2D"];

NSArray *fetchedCategory = [appDelegate getCategoryByName:text];
UIImageView *img=[[UIImageView alloc]initWithFrame:CGRectMake(10, 2, 20, 20)];
if(fetchedCategory.count)
{
for (int t=0; t<fetchedCategory.count; t++) {
Dealcategory_List *catList = [fetchedCategory objectAtIndex:t];
NSString *titleImage = [self URLEncodeString:[NSString stringWithFormat:#"%#",catList.image]];
NSURL *url = [NSURL URLWithString:titleImage];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *imgTabs = [UIImage imageWithData:data];
// [header2 setImage:imgTabs forState:UIControlStateNormal];
[imgTabs resizableImageWithCapInsets: UIEdgeInsetsMake(5, 10, 2, 0) resizingMode: UIImageResizingModeTile];
img.image= imgTabs;
}
}
else
{

if(fetchedNewsCategory.count > 0)
{
for (int t=0; t<fetchedNewsCategory.count; t++) {

break;
}
}
}
}
categoryTitle.textColor = color;
[labelView addSubview:img];
[labelView addSubview:categoryTitle];
[self.contentView addSubview:labelView];
UIView *labelView = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, kCategoryLabelHieght)];
You are defining a UIView but allocating a UILabel. iOS 8 is less tolerant to errors like this. Try to change it to
UIView *labelView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, kCategoryLabelHieght)];
I am using the following scrollview from a tutorial series. It works fine in portrait mode but the frame does not handle the switch to landscape mode. Is there a fast way to fix this? Thanks in advance.
- (void)viewDidLoad
{
[super viewDidLoad];
pageControlBeingUsed = NO;
NSString *plistFile = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:#"%#", self.displayRegion] ofType:#"plist"];

self.singleSituation = [SituationData objectAtIndex:selectedIndexPath];

[self.SituationScrollView addSubview:situationView];
[self.SituationScrollView addSubview:situationTitle];
[self.SituationScrollView addSubview:description];
}
use a global BOOL variable
BOOl isLandscape =NO;
while writing frames
situationView.frame = CGRectMake(isLandscape?0:0, isLandscape?0:0, isLandscape?320:480 , isLandscape?480:320);
in orientation method write again
if(orientation == Landscape)
{
isLandscape=YES;
}
else
{
isLandscape=NO;
}
situationView.frame = CGRectMake(isLandscape?0:0, isLandscape?0:0, isLandscape?320:480 , isLandscape?480:320);
Check it as a sample it will work depending on it you can use
A little googlefu revealed this SO thread in which Mike states loading the UIScrollView in the viewWillAppear method instead of the viewDidLoad method, then the UIScrollView should appear as desired.
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.
