Update Data and show it on UITableView iOS - iphone

Question

I have a problem: update data in UITableView. I want to get new data from parseXML that response from Server and them update new data to UITableView. **I used beloww code, but it does not show new data on Table View. I wrote a UpdateArray() function to check new data and then I compare 2 Array,if diff [Array count] then I call [tableview reloadData];
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [temp count];
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 90;
}
- (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];
UILabel *FileNameLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 0, 100, 30)];
FileNameLabel.backgroundColor = [UIColor clearColor];
FileNameLabel.font = [UIFont fontWithName:#"Helvetica" size:16];
FileNameLabel.font = [UIFont boldSystemFontOfSize:16];
FileNameLabel.textColor = [UIColor blackColor];
NSLog(#"Reseversed TEMP array %#",temp);
FileNameLabel.text =[temp objectAtIndex:indexPath.row];
[cell.contentView addSubview: FileNameLabel];
[FileNameLabel release];
UILabel *UploadTimeLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 20, 300, 25)];
UploadTimeLabel.backgroundColor = [UIColor clearColor];
UploadTimeLabel.font = [UIFont fontWithName:#"Helvetica" size:14];
UploadTimeLabel.textColor = [UIColor grayColor];
UploadTimeLabel.text = [UploadTimeArray objectAtIndex:indexPath.row];
[cell.contentView addSubview: UploadTimeLabel];
[UploadTimeLabel release];
UILabel *CompleteLabel = [[UILabel alloc] initWithFrame:CGRectMake(140, 12, 170, 25)];
CompleteLabel.backgroundColor = [UIColor clearColor];
CompleteLabel.font = [UIFont fontWithName:#"Helvetica" size:14];
CompleteLabel.textColor = [UIColor darkGrayColor];
CompleteLabel.text =#"Completed";
CompleteLabel.textAlignment = NSTextAlignmentRight;
[cell.contentView addSubview: CompleteLabel];
[CompleteLabel release];
}
return cell;
}
UpdateArray()
-(void)updateArray{
while (loop)
{
[NSThread sleepForTimeInterval:4.0];
[FileCompletedArray removeAllObjects];
// [temp removeAllObjects];
....
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:afRequest];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success");
NSString * parsexmlinput = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(#"Response in Loop CompleteView: %#", parsexmlinput);
// dispatch_async(dispatch_get_main_queue(), ^{
[self parseXMLFile:parsexmlinput];
NSLog(#"File Completed array: %#", FileCompletedArray);
NSLog(#"File Temp out array: %#", temp);
NSLog(#"File Completed count: %lu",(unsigned long)[ FileCompletedArray count]);
NSLog(#"File Temp out count: %lu", (unsigned long)[temp count]);
// NSLog(#"State: %#", state);
if([FileCompletedArray count ] != [temp count])
{
[temp removeAllObjects];
temp= [FileCompletedArray mutableCopy];
[_tableView reloadData];
}
else
{
NSLog(#"2 array equal");
}
//});
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"error: %#", error);
}
];
[httpClient enqueueHTTPRequestOperation:operation];
}
}
Can you help me? Thanks in advance.

Answer 1

I dont See that you call reloadData.
EDIT:
You must check that
1-Temp is having objects i mean that [temp count] is not returning zero.
2-The if condition that checks the two arrays is triggered . I mean that reload data is called.
3-You can make a breakpoint after cell.contetview addsubview and check what the cell contain now?

Answer 2

before you call
[_tableView reloadRowsAtIndexPaths:[_tableView indexPathsForVisibleRows]
withRowAnimation:UITableViewRowAnimationNone];
you have to call
[_tableView beginUpdates];
...
[_tableView endUpdates];
or call
[_tableView reloadData];

Answer 3

If you refresh table view then try this line & check:
[[self mytableview] reloadData];
mytableview is obj of tableview you give here your tableview object.
