Releasing custom class object - iphone

Question

I have a class called Res as follow
#interface Res : NSObject {
int _id;
NSString *_name;
NSString *_comments;
// ... and to many other objects.
}#property (nonatomic) int id;
#property (nonatomic, retain) NSString *name;
#property (nonatomic, retain) NSString *comments;
On my view I have a UITableView, I want user to enter values in UITextfield inside UITableViewCell so I have added below code
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
//code for creating cell
switch (indexPath.row) {
case 0:
// Label
[[cell textLabel] setText:#"Name :"];
// Textbox
UITextField *_txtName = [[UITextField alloc] initWithFrame:CGRectMake(100, 0, 180, 44)];
[_txtName setDelegate:self];
[_txtName setTag:0];
[cell.contentView addSubview:_txtName];
[_txtName release], _txtName = nil;
break;
case 1:
// ......
}
Now when user enter values in textbox I get it via following method
- (void)textFieldDidEndEditing:(UITextField *)textField
{
switch ([textField tag]) {
case 0:
[_resTemp setName:[textField text]];
break;
default:
break;
}
}
I declared _resTemp variable as instance variable in my .h file
on ViewDidLoad method I write _resTemp = [[Res alloc] init];
and on ViewDidUnload method I release it like [_resTemp release];
and I also release it same way in dealloc method.
Still I get memory leaks regarding this variable.
I do not get where to release this object or do I need to change my logic.
Can anyone give me some links that refers to code for data entry in UITableView?

Answer 1

You should define a dealloc method in your Res class.
- (void)dealloc
{
[_name release];
[_comments release];
[super dealloc];
}
The method will release objects contained in your Res object before releasing it.
