array returns null value ,arr = [[tempDict1 valueForKey:#"rates"] componentsSeparatedByString:#";"]; - iphone

Question

I am having a problem with displaying NSArray values in a UITableView. In my code I am getting nil value.
arr = [[tempDict1 valueForKey:#"rates"] componentsSeparatedByString:#";"];
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[connection release];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
self.responseData = nil;
values = [responseString JSONValue];
array = [[NSMutableArray alloc] init];
NSMutableArray *arrTitle = [[NSMutableArray alloc] init];
NSMutableArray *arrValues = [[NSMutableArray alloc] init];
array =[values valueForKey:#"rates"];
NSLog(#"array values:--> %#",array);
// NSLog(#"values:--> %#",values);
// NSLog(#"Particular values:--> %#",[[values valueForKey:#"rates"] valueForKey:#"AED"]);
tempDict1 = (NSMutableDictionary *)array;
NSArray *arr;// =[[NSArray alloc]init];
arr = [[tempDict1 valueForKey:#"rates"] componentsSeparatedByString:#";"];
NSLog(#"arr-->%#",arr);
NSString *subStar = #"=";
[arrTitle removeAllObjects];
[arrValues removeAllObjects];
for (int i=0; i<[arr count]-1; i++)
{
[arrTitle addObject:[[arr objectAtIndex:i] substringToIndex:NSMaxRange([[arr objectAtIndex:i] rangeOfString:subStar])-1]];
[arrValues addObject:[[arr objectAtIndex:i] substringFromIndex:NSMaxRange([[arr objectAtIndex:i] rangeOfString:subStar])]];
NSLog(#"arrTitle is:--> %#",arrTitle);
}
tempDict1 = (NSMutableDictionary*)[array objectAtIndex:0];
array = [values valueForKey:#"rates"];
NSLog(#"tempDict--%#",[tempDict1 objectForKey:#"AED"]);
[array retain];
[tbl_withData reloadData];
}
uitableview code is below
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSLog(#"array-->%#",array);
return [array count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
intIndexPath = indexPath.row;
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
cell.textLabel.adjustsFontSizeToFitWidth = YES;
cell.textLabel.font = [UIFont systemFontOfSize:8];
cell.textLabel.numberOfLines = 4;
}
// NSLog(#"data is like:--> %#",array);
// cell.textLabel.text= [NSString stringWithFormat:#"%#",[array objectAtIndex:intIndexPath]];
cell.textLabel.text =[array objectAtIndex:intIndexPath];
return cell;
}

Look through table view programming guide
https://developer.apple.com/library/ios/#documentation/UserExperience/Conceptual/TableView_iPhone/AboutTableViewsiPhone/AboutTableViewsiPhone.html
You have to implement UITableView delegate methods in your class to fill table view with content.
Also see this:
https://developer.apple.com/library/ios/#documentation/UserExperience/Conceptual/TableView_iPhone/CreateConfigureTableView/CreateConfigureTableView.html#//apple_ref/doc/uid/TP40007451-CH6-SW10
Here is code:
//this is your dictionary:
self.values = [[[NSMutableDictionary alloc] init] autorelease];
//filled it with values:
[self.values setObject:#"201" forKey:#"ams"];
[self.values setObject:#"500.50" forKey:#"hyd"];
[self.values setObject:#"200.10" forKey:#"guj"];
[self.values setObject:#"400" forKey:#"afgd"];
//now get an array of keys out of it. Can do it anywehe... For example in connectionDidFinishLoading method
self.keys = [[[NSArray alloc] initWithArray:[values allKeys]] autorelease];
Now cellForRoAtIndexPath method:
- (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.adjustsFontSizeToFitWidth = YES;
cell.textLabel.font = [UIFont systemFontOfSize:8];
cell.textLabel.numberOfLines = 4;
}
NSString *currentKey = [self.keys objectAtIndex:indexPath.row];
NSString *currentValue = [self.values objectForKey:currentKey];
NSString *cellText = [NSString stringWithFormat:#"%#:%#", currentKey, currentValue];
cell.textLabel.text = cellText;
return cell;
}
It worked on my machine..
