how to Display data get from JSON in View controller - ios

I have idea how to display data in UITableViewController in cell by index.row but i don't have idea how to show data in viewController
for e.g.
when i use UITableViewController that time,
NSString *str = [NSString stringWithFormat:#"%#", [[self.data
objectAtIndex:indexPath.row ] valueForKey:#"profile_image"]]; // data
is my array
this code will get image from array and set it in particular cell with the help of index.row.
but when i am using UIViewController then how i should set data for particular view??
Please provide me your guidance for this issue that how can i set image form array to my ViewController as i set it in UITableViewController by objectAtIndex:indexPath.row .
Thanks

i asked the above question but i got answer myself after many research and defiantly with the help of my stackoverflow's intelligent friends.
so i like to post my answer.
my answer is if i take int value i and then i use it in my function then it look like below code..
[requestDynamic startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
// Insert your code here
NSLog(#"%#",result);
self.arrData = nil;
self.arrData = [[NSMutableArray alloc]init];
self.arrData = [result[#"data"] mutableCopy];
int i =0;
// NSString *strImage1 = [NSString stringWithFormat:#"%#",[[self.arrData objectAtIndex:i]valueForKey:#"picture"]];
NSString *strComment =[NSString stringWithFormat:#"%#", [[self.arrData objectAtIndex:i ]valueForKey:#"message"]];
NSString *strLike = [NSString stringWithFormat:#"%#", [[[[self.arrData objectAtIndex:i]valueForKey:#"likes"]valueForKey:#"summary"]valueForKey:#"total_count"]];
NSString *strCommentCount = [NSString stringWithFormat:#"%#", [[[[self.arrData objectAtIndex:i]valueForKey:#"comments"]valueForKey:#"summary"]valueForKey:#"total_count"]];
CustomSocialView *imageView1 = [[CustomSocialView alloc] initWithFrame:CGRectMake(0, 0, width, height)];
[imageView1 setContentText:strComment like:strLike comment:strCommentCount];
may be this question and answer is silly for you all experienced people but it is very important for me and some others like me.
so i post answer as i got it.
Thank you

image not showing in UIImage from cached data

I cant possibly get the image that i parsed from the XML to show on my UIImageView using the code below. Am I doing something wrong because I checked it using NSLog to show if there is a link and apparently there is.
NSString *imageURL = [currentData.imageLink];
NSLog(#"this is link = %#", imageURL);
[cachedList addObject:imageURL];
[myCache setObject:cachedList forKey:#"imageURL"];
cachedList = [myCache objectForKey:#"imageURL"]; /where cachedList is NSMutableArray
for(id obj in cachedList){
NSLog(#"value = %#", obj); //to show value
cell.imageShow.image = [UIImage imageNamed:obj];
}
and also I tried doing the below code, but it gives me an error.
if (cachedList != nil) {
cell.imageShow.image = [UIImage imageNamed:[cachedList valueForKey:#"imageURL"]];
}
I think if you are using UITableView then this is the thing i have used and i prefer for tableview

iOS FGallery objective c assigning string value dynamically

It is a bit complicated to explain my problem. I am using FGallery library https://github.com/gdavis/FGallery-iPhone and especially its feature to load images from URL addresses. When I hardcode the URL path it works super, but wen I pass a string variable to the class which I have created it doesn't work. I tried to debug it and it seems that everything is ok, there is a string assigned to the variable and everything, but do not show the picture. I am doing this in a loop and using ARC.
-(void) loadSoftia
{
//======================================================================================
//THIS WORKS CORRECTLY!!!
wcSofia = [[NSMutableArray alloc] init];
Webcam *s1 = [[Webcam alloc]init];
s1.description=#"Sofia";
s1.location = #"http://www.ampthillweatherstation.info/currentweather/webcamimage.jpg";
[wcSofia addObject:s1];
//======================================================================================
NSMutableString *urlGetOthersLocations =[NSMutableString stringWithFormat:#"http://%#/WebHandlers/%#", #"192.168.188.204", #"BGCam.ashx"];
ServerResponse *serverResponseOthersLocations = [HelperViewController getJsonDataFromTheServer:urlGetOthersLocations];
if(serverResponseOthersLocations.data!=nil)
{
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:serverResponseOthersLocations.data
options:NSJSONReadingMutableLeaves|NSJSONReadingMutableContainers
error:nil];
[wcSofia removeAllObjects];
Webcam *wc;
int i=0;
for (NSDictionary *locationsDic in dic){
NSString *key;
for ( key in locationsDic) {
NSLog(#"%# = %#", key, [locationsDic objectForKey: key]);
}
NSLog(#"%#", [locationsDic objectForKey:#"URL"]);
NSLog(#"%# = %#", locationsDic, [locationsDic objectForKey: locationsDic]);
NSString *url =[locationsDic objectForKey:#"URL"];
// NSLog(#"%#", url);
NSMutableString* theString = [NSString stringWithFormat:#"%i ",i];
wc = [[Webcam alloc]initWithLocation: [NSString stringWithFormat:#"%#", url] withDescription:#"description"];
wc.location = url;//DOESNT WORK!
wc.description =#"София";// theString;//[NSString stringWithFormat:#"%#", #"aa"]; // #"София";
wc.location = #"http://media.borovets-bg.com/cams/channel?channel=61";//IT WORKS BECAUSE IT IS HARDCODED
if(wcSofia!=nil)
{
[wcSofia addObject:wc];
NSLog(#"%#", wc.location);
}
i++;
}
}
}
I have commented a section of the code which works and which doesn't.
I suppose that you are not going to need the whole program, because it make requests to my local web server to get the URL addresses and descriptions, but trust me this thing works perfect.
Thank you for your help in solving that mystery.

Separate two strings from one array element

I was wondering if anyone could lend some assistance. Basically I am calling a web service and then trying to get the large hosted image url. The output from the web service is so:
images = (
{
hostedLargeUrl = "http://i.yummly.com/Crispy-roasted-chickpeas-_garbanzo-beans_-308444.l.jpg";
hostedSmallUrl = "http://i.yummly.com/Crispy-roasted-chickpeas-_garbanzo-beans_-308444.s.jpg";
}
);
The main problem is that the two strings are in only one of my array elements when I think they should be in 2. Also I'm not 100% but possibly they may be a dictionary :-S I'm just not sure. My code is as follows:
NSArray *imageArray = [[NSArray alloc]init];
imageArray = [self.detailedSearchYummlyRecipeResults objectForKey:#"images"];
NSLog(#"imageArray: %#", imageArray);
NSLog(#"count imageArray: %lu", (unsigned long)[imageArray count]);
NSString *hostedLargeurlString = [imageArray objectAtIndex:0];
NSLog(#"imageArrayString: %#", hostedLargeurlString);
The output (nslog's) from the above code is:
2013-04-28 18:59:52.265 CustomTableView[2635:11303] imageArray: (
{
hostedLargeUrl = "http://i.yummly.com/Crispy-roasted-chickpeas-_garbanzo-beans_-308444.l.jpg";
hostedSmallUrl = "http://i.yummly.com/Crispy-roasted-chickpeas-_garbanzo-beans_-308444.s.jpg";
}
)
2013-04-28 18:59:52.266 CustomTableView[2635:11303] count imageArray: 1
2013-04-28 18:59:52.266 CustomTableView[2635:11303] imageArrayString: {
hostedLargeUrl = "http://i.yummly.com/Crispy-roasted-chickpeas-_garbanzo-beans_-308444.l.jpg";
hostedSmallUrl = "http://i.yummly.com/Crispy-roasted-chickpeas-_garbanzo-beans_-308444.s.jpg";
}
Does anyone have any idea how I can seperate the one element into hostedlargeUrl and hostedsmallUrl respectively?
Any help you can provide is greatly appreciated!
Actually the images array contains a dictionary
images = (
{
hostedLargeUrl = "http://i.yummly.com/Crispy-roasted-chickpeas-_garbanzo-beans_-308444.l.jpg";
hostedSmallUrl = "http://i.yummly.com/Crispy-roasted-chickpeas-_garbanzo-beans_-308444.s.jpg";
}
);
so :
NSDictionary *d = [self.detailedSearchYummlyRecipeResults objectForKey:#"images"][0];
NSString *largeURL = d[#"hostedLargeUrl"];
NSString *smallURL = d[#"hostedSmallUrl"];
The value of [imageArray objectAtIndex:0] is a NSDictionary. You've incorrectly specified it as a NSString. You need the following:
NSDictionary *hostedLarguerDictionary =
(NSDictionary *) [imageArray objectAtIndex:0];
and then to access the 'large url' use:
hostedLarguerDictionary[#"hostedLargeUrl"]
or, equivalently
[hostedLarguerDictionary objectForKey: #"hostedLargeUrl"];
looks like an array with in an array so
NSArray* links = [self.detailedSearchYummlyRecipeResults objectForKey:#"images"];
NSString* bigLink = [links objectAtIndex:0];
NSString* smallLink = [links objectAtIndex:1];
or it could be a dictionary
NSDictionary* links = [self.detailedSearchYummlyRecipeResults objectForKey:#"images"];
NSString* bigLink = [links objectForKey:#"hostedLargeUrl "];
NSString* smallLink = [links objectForKey:#"hostedSmallUrl "];
you can see the class of the object by printing out the class name
NSLog(#"Class Type: %#", [[self.detailedSearchYummlyRecipeResults objectForKey:#"images"] class]);

csv to core data method error 2012

I have read a few posts and found a method. I adapted it to my app, however at [self saveContext]; I get a bad instruction error.
Please let me know why, and if this method makes sense. Also I am using \r because in the csv each item is in its own row.
Thank you in advance
-(void)addData{
NSString *paths = [[NSBundle mainBundle] resourcePath];
NSString *bundlePath = [paths stringByAppendingPathComponent:#"coredatainfo.csv"];
NSString *dataFile = [[NSString alloc] initWithContentsOfFile:bundlePath];
NSArray *dataRows = [dataFile componentsSeparatedByString:#"\r"];
[dataFile release];
FirstCDitem *myItem;
for (int i = 0 ; i < [dataRows count] ; i++)
{
NSArray *dataElements = [[dataRows objectAtIndex:i] componentsSeparatedByString:#","];
NSLog(#"Added: %d %#",i,dataElements);
myItem = (FirstCDitem *)[NSEntityDescription insertNewObjectForEntityForName:#"FirstCDitem" inManagedObjectContext:[self managedObjectContext]];
[FirstCDitem setTitle:[dataElements objectAtIndex:i]];
[self saveContext];
}
}
There are two problems in this code line:
[FirstCDitem setTitle:[dataElements objectAtIndex:i]];
i is the current row number, so it probably makes no sense to use it as index to the dataElements array. Perhaps you want the first element in the row?
setTitle must sent to the instance myItem, not to the class FirstCDItem.
So the line should look like this:
[myItem setTitle:[dataElements objectAtIndex:0]];

Question regarding errand on UITableView creation from iPhone Addressbook

I have a question regarding the AddressBook Framework for iOS. The situation is as follows:
I'm trying recreate the contacts view from the phone application, but I want to show the contact's phone numbers in the same view. So if a contact has more than one number, his name will be in the TableView multiple times, each time with a different number.
I am trying to accomplish that by extracting all the information I need when the view loads and after that, populate the TableView with the appropriate values from an NSArray consisting of NSDictionaries containing the contact's information.
This works great except for one thing... The contact's phonenumbers and labels are read correctly and stored in the dictionary, but when I read them out later, they seem to have vanished.
Here's my code for generating the NSDictionaries, I bet it's some kind of memory management error or something completly stupid. I hope anyone can help me, thanks a lot in advance!
persons = [[NSMutableArray alloc] init];
ABAddressBookRef addressBook = ABAddressBookCreate();
ABRecordRef source = ABAddressBookCopyDefaultSource(addressBook);
NSArray *people = (NSArray *)ABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering(addressBook, source, kABPersonSortByLastName);
for (id record in people)
{
ABMultiValueRef numbers = ABRecordCopyValue((ABRecordRef)record, kABPersonPhoneProperty);
for (CFIndex i = 0; i < ABMultiValueGetCount(numbers); ++i) {
CFStringRef label = ABAddressBookCopyLocalizedLabel(ABMultiValueCopyLabelAtIndex(numbers, i));
CFStringRef number = ABMultiValueCopyValueAtIndex(numbers, i);
CFStringRef firstNameRef = ABRecordCopyValue((ABRecordRef)record, kABPersonFirstNameProperty);
CFStringRef lastNameRef = ABRecordCopyValue((ABRecordRef)record, kABPersonLastNameProperty);
CFDataRef imageDataRef = ABPersonCopyImageDataWithFormat((ABRecordRef)record, kABPersonImageFormatThumbnail);
NSString *firstName = [NSString stringWithFormat:#"%#", firstNameRef];
NSString *lastName = [NSString stringWithFormat:#"%#", lastNameRef];
NSString *pLabel = [[NSString alloc] initWithFormat:#"%#", label];
NSString *pNumber = [NSString stringWithFormat:#"%#", number];
UIImage *image = [UIImage imageWithData:(NSData*)imageDataRef];
NSDictionary *personDict = [NSDictionary dictionaryWithObjectsAndKeys:firstName, #"firstName", lastName, #"lastName", image, #"image", pNumber, #"phoneNumber", pLabel, #"label", nil];
NSLog(#"In %# - %#", pLabel, pNumber);
[persons addObject:personDict];
CFRelease(firstNameRef);
CFRelease(lastNameRef);
//CFRelease(imageDataRef);
CFRelease(label);
CFRelease(number);
}
}
CFRelease(addressBook);
CFRelease(source);
[people release];
Finally could resolve this myself. Apparently I was adding some nil-images to the dictionaries which they couldn't handle.
