Question

I have NSArray elements which is implemented from NSSet and if i tried to display the elements in Table View Cell i’m getting BAD ACCESS issue at tableView numberOfRowsInSection part.Here is my code

- (void)viewDidLoad
{
[super viewDidLoad];




jsonurl=[NSURL URLWithString:@"http://www.sample.net/products.php"];//NSURL

jsondata=[[NSString alloc]initWithContentsOfURL:jsonurl];//NSString
jsonarray=[[NSMutableArray alloc]init];//NSMutableArray

self.jsonarray=[jsondata JSONValue];

array=[jsonarray valueForKey:@"post_title"];

set = [NSSet setWithArray:array];//NSMutableSet
array=[set allObjects];//NSArray


NSLog(@"%@",array);



}


#pragma mark - Table view data source

  - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [array 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];



}
// Configure the cell...

cell.textLabel.text = [self.array objectAtIndex: [indexPath row]];    
return cell;
}

Kindly help please.Thanks in advance.

In your code you are not allocating the array. You are setting an autoreleased object to that array that’s why you are getting this error.

Replace array=[set allObjects]; with array=[[set allObjects] retain];
