I have a NSURL request that brings back an array of "name" and "phone", "etc"... The "name" Key shows up fine on the master table, but I'm having trouble figuring out how to get the rest of the array to show up on the detail table when I select the row. (I have the DetailerTableViewController working to accept the view). Any help would be appreciated.
Thanks,

You need to implement:
- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
to handle row selection and to push the view controller for the detail view.

Any ideas? Thanks in advance.
You're returning the cell twice in the same scope, try to delete the first return cell;, also you're calling reloadData on the table just before the for loop; in this case probably the dataSource of the table is still empty, so call reloadData just after the for loop.
EDIT:
It's strange what is happening, the objectFromString must return a NSArray or a NSDictionary but it seems that is pointing to an NSSet. I can suggest 2 things in addition:
It seems that you're not usig ARC since you're calling autorelease on the UITableViewCell. In this case you're leaking parser and json_string in the viewDidLoad, so release them.
Make sure to call [super viewDidLoad]; (you're not doing this in your code).
Maybe because you set the type of obj as id. It is too generic and may not know how to respond to valueForKey. Have you tried declaring obj as an NSDictionary * instead? Like the code below:
NSDictionary *obj = [statuses objectAtIndex:indexPath.row];
NSString *name = [obj valueForKey:#"Title"];
Use the Below code in your ViewDidload and Run the Project , it will work.
Note :You're returning the cell twice, try to delete the first return
cell;
- (void)viewDidLoad
{
[super viewDidLoad];
statuses=[[NSMutableArray alloc]init];

{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] ;
}
id obj = [statuses objectAtIndex:indexPath.row];
cell.textLabel.text =[obj valueForKey:#"Title"];
return cell;
}
Yes I was thinking right, statuses is not NSArray, it is NSSet so if you call objectAtIndex on NSSet it will crash.To get array convert NSSet into NSArray.
NSArray *array =[statuses allObjects];
- (void)viewDidLoad
{
NSString *dictStr=#"{\"Id\": 1,\"Title\": \"Tamil to English\",\"AltTitle\": \"த|மி|ழ்| |மூ|ல|ம்| |ஆ|ங்|கி|ல|ம்\",\"Description\": \"Learn English through Tamil\",\"Code\": 1,\"Version\": \"1.0\",\"SourceLanguageIndicator\": \"அ\",\"TargetLanguageIndicator\": \"A\",\"SourceLanguageCode\": \"ta\",\"TargetLanguageCode\": \"en\",\"Updated\": \"2013-02-21T03:33:19.6601651+00:00\"}";

if (cell==nil) {
cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
cell.textLabel.text=[rootDict valueForKey:[keys objectAtIndex:indexPath.row]];
return cell;
}
remember rootDict and keys will be declared as global.

How to Get Data from a PList into UITableView?
I have a plist with Dictionary and numbers of strings per dictionary.show into the url below.and this list of items is in thousands in the plist.
Now want to display these list into the tableview
.
now how can i display this plist into the UITableView
what I am trying is:
- (id)readPlist:(NSString *)fileName
{
NSString *error;
NSPropertyListFormat format;
id plist;
NSString *localizedPath = [[NSBundle mainBundle] pathForResource:#"A" ofType:#"plist"];
dic =[NSDictionary dictionaryWithContentsOfFile:localizedPath];
plist = [NSPropertyListSerialization propertyListFromData:dic mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&error];
if (!plist) {
NSLog(#"Error reading plist from file '%s', error = '%s'", [localizedPath UTF8String], [error UTF8String]);
[error release];
}
return plist;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
dict =[self readPlist:#"A"];
return dict.allKeys.count;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
dict = [self readPlist:#"A"];
key = [dict.allKeys objectAtIndex:section];
return [[dict valueForKey:key] count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [[dict objectForKey:key] objectAtIndex:indexPath.row];
return cell;
}
UPDATE 2: You need to set the delegate and datasource for your tableView in your xib or ViewController.
In your ViewController.h file
#interface ViewController:UIViewController <UITableViewDelegate, UITableDataSource>
Try this code which I have written for you.
- (void)viewDidLoad {
tableView.delegate = self;
tableView.dataSource = self;
NSString *path = [[NSBundle mainBundle] pathForResource:#"Filename" ofType:#"plist"];
NSArray *contentArray = [NSArray arrayWithContentsOfFile:path];
// Having outlet for tableArray variable.
tableArray = [[NSMutableArray alloc]initWithArray:contentArray copyItems:YES];
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return [tableArray count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// In your case dictionary contains strings with keys and values. The below line returns dictionary only. not array..
NSDictionary *dictionary = [tableArray objectAtIndex:section];
return dictionary.allKeys.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"MyCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:cellIdentifier];
}
NSDictionary *dictionary = [tableArray objectAtIndex:indexPath.section];
NSArray *keysArray = dictionary.allKeys;
// This below line display the key in textLabel
cell.textLabel.text = [keysArray objectAtIndex:indexPath.row];
// Below line will display the value of a key in detailTextLabel.
cell.detailTextLabel.text = [dictionary valueForKey:[keysArray objectAtIndex:indexPath.row]];
return cell;
}
UPDATE 2: After I have seen your plist in my MAC, I have found out that we are working with array of dictionaries in your A.plist.
So I found there is a bug in our code itself. Not in the plist file and you can use your 8000 data plist too.. Its working too. I have checked out totally. Now you can get the above Code and start work with.
store Plist data in array
- (id)readPlist:(NSString *)fileName
{
NSString *error;
NSPropertyListFormat format;
id plist;
NSString *localizedPath = [[NSBundle mainBundle] pathForResource:#"A" ofType:#"plist"];
// declare your array in .h file
array = [NSArray arrayWithContentsOfFile:localizedPath];
plist = [NSPropertyListSerialization propertyListFromData:dic mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&error];
if (!plist) {
NSLog(#"Error reading plist from file '%s', error = '%s'", [localizedPath UTF8String], [error UTF8String]);
[error release];
}
return plist;
}
and then write it in table
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [array objectAtIndex:indexPath.row] valueForKey:#"keyname"];;
return cell;
}
I want to display Plist to the UITableView .By my below code I can display one key values that is list of states. but i want to display all the values of three tables.
- (id)readPlist:(NSString *)fileName
{
NSData *plistData;
NSString *error;
NSPropertyListFormat format;
id plist;
NSString *localizedPath = [[NSBundle mainBundle] pathForResource:fileName ofType:#"plist"];
plistData = [NSData dataWithContentsOfFile:localizedPath];
plist = [NSPropertyListSerialization propertyListFromData:plistData mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&error];
if (!plist) {
NSLog(#"Error reading plist from file '%s', error = '%s'", [localizedPath UTF8String], [error UTF8String]);
}
return plist;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [[[self readPlist:#"sample"] objectForKey:#"ListOfStates"] count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [[[self readPlist:#"sample"] objectForKey:#"ListOfStates"] objectAtIndex:indexPath.row];
return cell;}
MY output comes only listofkeystates values
is it also possible to display key name with values
Maybe use table sections...
-(NSInteger) numberOfSectionsInTableView:(UITableView *)tableView {
NSDictionary* dict = [self readPlist:#"sample"];
return dict.allKeys.count;
}
-(NSString*) tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
NSDictionary* dict = [self readPlist:#"sample"];
return [dict.allKeys objectAtIndex:section];
}
-(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
NSDictionary* dict = [self readPlist:#"sample"];
NSString* key = [dict.allKeys objectAtIndex:section];
return [[dict valueForKey:key] count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSDictionary* dict = [self readPlist:#"sample"];
NSString* key = [dict.allKeys objectAtIndex:indexPath.section];
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text = [[dict objectForKey:key] objectAtIndex:indexPath.row];
return cell;
}
just try to get data in NSDictionary and NSArray and then use it in UITableView
NSString *file = [[NSBundle mainBundle] pathForResource:#"sample" ofType:#"plist"];
NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:file];
and use tableValue with its name like bellow...
NSArray *array = [dict objectForKey:#"ListOfStates"];
NSLog(#"%#", array);
i hope this help you..
EDIT : Corrected some typo mistakes
The idea
Loading plist in a dictonary
optional : sort it (!)
create the array of data for each section
create the array of section
Then implement the following things
viewDid load -> load the plist file in a dictionary, create an array of the sections and a dictionary of the data
numberOfSectionsInTableView -> the number of sections. In your case the number of keys
numberOfRowsInSection -> the number of rows of each section
titleForHeaderInSection -> for each section, the title of the section
cellForRowAtIndexPath -> the data of all row
sectionIndexTitlesForTableView -> the array that holds all you sections names. In your case all the keys
assuming you have a property called mySections and a property called myData
also assuming you use storyboard with standard cell with recycle identifier "Cell"
#synthesize mySections
#synthesize myData
- (void)viewDidLoad
{
[super viewDidLoad];
//LOADING THE PLIST FILE
//Create a string representing the file path
NSString *plistPath = [bundle pathForResource:#"yourFilename" ofType:#"plist"];
//Load the file in a dictionnary
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:plistPath];
self.myData = dict;
//SORTING THE DICTIONARY
NSArray *dicoArray = [[self.myData allKeys] sortedArrayUsingComparator:^(id firstObject, id secondObject) {
return [((NSString *)firstObject) compare:((NSString *)secondObject) options: NSCaseInsensitiveSearch];

//Return the number of sections.
return [self.mySections count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
NSString *key = [self.mySections objectAtIndex:section];
NSArray *dataInSection = [self.myData objectForKey:key];
return [dataInSection count];
}
-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
NSString *key = [self.mySections objectAtIndex:section];
return [NSString stringWithFormat:#"%#", key];
}
-(NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {
return self.mySections;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
NSUInteger section = [indexPath section];

return cell;

for (NSDictionary *lesson in list)
{
// 3 ...that contains a string for the key "stunde"
NSString *content = [lesson objectForKey:#"Street"];
NSLog(#"%#", content);
}
// Do any additional setup after loading the view, typically from a nib.
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [jsonArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = (UITableViewCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
return cell;
}
I'm using this JSon.php file.
{"Steffan's Party":{"Street":"774 Hoodwinked Avenue","City":"Sacramento","State":"California"},"Dewan's Party":{"Street":"2134 Statewide Lane","City":"New York","State":"New York"},"Austin's Party":{"Street":"9090 Gravink Court","City":"Woodland","State":"California"}}
This is a link to the website http://oo.mu/json.php.
What I'm trying to do here is parse each array in it's own UITableView cell. Example below, how can I do this?
Table Cell 1:
Steffan's Party
774 Hoodwinked Ave
Sacramento, California
Table Cell 2:
Dewan's Party
2134 Statewide Lane
New York, New York
How can I do this?
To get all keys and values from your current json do the following
in your viewDidLoad
NSString *yourJson = #"{\"Steffan's Party\":{\"Street\":\"774 Hoodwinked Avenue\",\"City\":\"Sacramento\",\"State\":\"California\"},\"Dewan's Party\":{\"Street\":\"2134 Statewide Lane\",\"City\":\"New York\",\"State\":\"New York\"},\"Austin's Party\":{\"Street\":\"9090 Gravink Court\",\"City\":\"Woodland\",\"State\":\"California\"}}";
SBJSON *json = [[SBJSON alloc] init];
NSDictionary *dic = [json objectWithString:yourJson error:NULL];
//NSMutableArray * keys; is defined in your interface .h file
//NSMutableArray * values; is defined in your interface .h file
keys = [[NSMutableArray alloc] init];
values = [[NSMutableArray alloc] init];
for(NSString *key in dic.keyEnumerator)
{
[keys addObject:key];
[values addObject:[dic objectForKey:key]];
}
now in your cellForRowAtIndexPath would look like this
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = (UITableViewCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
//Steffan's Party 774 Hoodwinked Ave Sacramento, California
NSString *partyName = [keys objectAtIndex:indexPath.row];
NSDictionary *dicValues = [values objectAtIndex:indexPath.row];
NSString *Street = [dicValues objectForKey:"Street"];
NSString *City = [dicValues objectForKey:"City"];
NSString *State = [dicValues objectForKey:"State"];
//Steffan's Party 774 Hoodwinked Ave Sacramento, California
NSString *fullString = [NSString stringWithFormat:#"%# %# %# %#", partyName, Street, City, State];
return cell;
}
Why are you using SBJsonParser? It's easier using only -JSONValue! Look:
NSDictionary *jsonDict = [jsonData JSONValue];
// you can declare it as ivar
Then, in -tableView:cellForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = (UITableViewCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
// that's how you can get key by index
NSString *key = [[jsonDict allKeys] objectAtIndex:indexPath.row];
NSDictionary *party = [jsonDict objectForKey:key];
NSString *street = [party valueForKey:#"Street"];
NSString *city = [party valueForKey:#"City"];
NSString *state = [party valueForKey:#"State"];
cell.textLabel.text = [NSString stringWithFormat:#"%# %# %#, %#", key, street, city, state];
return cell;
}
I have the following code to make a table from string turned into a dictionary:
- (void)viewDidLoad {
[super viewDidLoad];
testArray = [[NSArray alloc] init];
NSString *testString = #"Sam|26,Hannah|22,Adam|30,Carlie|32";
testArray = [testString componentsSeparatedByString:#","];
dict = [NSMutableDictionary dictionary];
for (NSString *s in testArray) {
testArray2 = [s componentsSeparatedByString:#"|"];
[dict setObject:[testArray2 objectAtIndex:1] forKey:[testArray2 objectAtIndex:0]];
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell.
if (testArray.count >indexPath.row) {
cell.textLabel.text = [[dict allKeys] objectAtIndex:[indexPath row]];
cell.detailTextLabel.text = [dict objectForKey:cell.textLabel.text];
}
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
What I would like is for the selected row title to be set as the title on my detail view.
I tried with:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
self.detailController.title = [[dict allKeys] objectAtIndex:[indexPath row]];
[self.navigationController pushViewController:self.detailController animated:YES];
}
But I get an "EXC_BAD_ACCESS" error.
It works fine if I use #"1" as title, it's just something with my dictionary call that's wrong, I assume.
Make dict a retained dictionary instead of an autoreleased one.
I.E. declare it maybe like this:
dict = [[NSMutableDictionary alloc] initWithCapacity: [testArray count]];
in your viewDidLoad method. Make sure to release it when viewDidUnload is called.
Also, make sure of the number of keys in your dict before calling:
self.detailController.title = [[dict allKeys] objectAtIndex:[indexPath row]];
So, I would do:
if(dict && ([[dict allKeys] count] > [indexPath row])
{
self.detailController.title =
[[dict allKeys] objectAtIndex:[indexPath row]];
} else {
self.detailController.title = #"Here's a problem";
}
Did you implement these UITableView delegate methods ? All these are needed. Also can you post more detailed StackTrace.
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return [resultSet count];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}

heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 280.0;
}
