Why willDisplayCell not be called

in my MainPageDataSource.m I code like this:

#import "MainPageDataSource.h"
#import "LoadResult.h"
#import "CustomTTTableSubtitleItem.h"
#import "CustomTTTableSubtitleItemCell.h"
#import "XYDefaultStylesheet.h"


@implementation MainPageDataSource


- (id)init {
if (self = [super init]) {
    _mainPageModel = [[MainPageMode alloc] init];
    _allResults = [[NSMutableArray alloc] init];                   
}
return self;
}


- (id<TTModel>)model {
    return _mainPageModel;
}


- (void)tableViewDidLoadModel:(UITableView*)tableView 
{

[super tableViewDidLoadModel:tableView];

NSDateFormatter* dateFormat = [[NSDateFormatter alloc] init];   

[dateFormat setDateFormat:@"yyyy-MM-dd"];
for (LoadResult *result in [(id<TabModel>)self.model results]){
    NSTimeInterval formateSeconds = [result.resourceVersionTime doubleValue];
    NSString *dataFormatted =[dateFormat stringFromDate:[NSDate dateWithTimeIntervalSince1970:formateSeconds]]; 

    NSString *textCombine = [dataFormatted stringByAppendingFormat:@"/%@/%@\n%@", 
                             result.resourceVersion, result.resourceSize, result.resourceCatalog];





    [self.items addObject:[CustomTTTableSubtitleItem itemWithTitle:result.resourceName text:textCombine 
                                                          imageURL:result.resourceImagepath URL:nil
                                                  rightButtonTitle:result.resourcePrice appRate:result.resourceRate]];


}


    TT_RELEASE_SAFELY(dateFormat);


}

- (Class)tableView:(UITableView*)tableView cellClassForObject:(id) object { 

if ([object isKindOfClass:[CustomTTTableSubtitleItem class]]) { 
    return [CustomTTTableSubtitleItemCell class];       
} else { 
    return [super tableView:tableView cellClassForObject:object]; 
}
}



- (void)tableView:(UITableView*)tableView prepareCell:(UITableViewCell*)cell forRowAtIndexPath:(NSIndexPath*)indexPath {
cell.accessoryType = UITableViewCellAccessoryNone;
}
- (UITableViewCell *)tableView:(UITableView *)tableView
     cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(@"indexPath.row11111 ===== %d",indexPath.row);
UITableViewCellStyle style =  UITableViewCellStyleValue2;
CustomTTTableSubtitleItemCell *cell = (CustomTTTableSubtitleItemCell *)[tableView dequeueReusableCellWithIdentifier:@"CustomTTTableSubtitleItemCell"];
if (cell == nil) {
    NSLog(@"new le cell");
    cell = [[[CustomTTTableSubtitleItemCell alloc] initWithStyle:style reuseIdentifier:@"CustomTTTableSubtitleItemCell"] autorelease];

}

if (indexPath.row % 2 == 0) {
    cell.contentView.backgroundColor = TTSTYLEVAR(tableCellColor1);
}else {
    cell.contentView.backgroundColor = TTSTYLEVAR(tableCellColor2);
}

return cell;
}



- (void)dealloc {
TT_RELEASE_SAFELY(_mainPageModel);
[super dealloc];
}

@end

willDisplayCell never been called. What's wrong?

Considering the fact there's no such function in the TTTableViewDataSource class, i'm not sure why it should be called.

maybe you mean this function:

 - (void)tableView:(UITableView*)tableView cell:(UITableViewCell*)cell
    willAppearAtIndexPath:(NSIndexPath*)indexPath;

This function get called each time a table cell is displayed in the TTTableView. I never had the need to use it. I think it's better to keep all the logic in the table cell classes.
