При попытке загрузить пользовательский UITableViewCell из пера я не могу отобразить ячейку, только если я установил reuseIdentifier для ячейки прототипа в основной раскадровке. Если это значение пусто, я получаю предупреждение от xcode, однако код работает правильно. У меня есть подобный код в нескольких других контроллерах, но это единственный, который представляет эту проблему.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = @"AssetsTableCell";
AssetsTableCell *assetTableCell = (AssetsTableCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
int rightIndex = (indexPath.row * 4);
int rightMiddleIndex = (indexPath.row * 4) + 1;
int leftMiddleIndex = (indexPath.row * 4) + 2;
int leftIndex = (indexPath.row * 4) + 3;
if (assetTableCell == nil) {
NSArray *topLevelObjects;
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"AssetsTableCell_iPhone" owner:nil options:nil];
assetTableCell = (AssetsTableCell *)[topLevelObjects objectAtIndex:0];
[assetTableCell setDelegate:self];
}
// Need to collect the badge details in groups of 4.
@try {
NSArray *rowArray = [NSArray arrayWithObjects:[remoteContainers objectAtIndex:rightIndex],
[remoteContainers objectAtIndex:rightMiddleIndex],
[remoteContainers objectAtIndex:leftMiddleIndex],
[remoteContainers objectAtIndex:leftIndex],
nil];
NSDictionary *cellData = [NSDictionary dictionaryWithObjectsAndKeys:
[rowArray objectAtIndex:0], @"LEFT_CONTAINER",
[rowArray objectAtIndex:1], @"LEFT_MIDDLE_CONTAINER",
[rowArray objectAtIndex:2], @"RIGHT_MIDDLE_CONTAINER",
[rowArray objectAtIndex:3], @"RIGHT_CONTAINER", nil];
[assetTableCell populateCellData:cellData];
}
@catch (NSException *exception) {
DLog(@"Exceeds boundary of remoteContainers array by %d.", ([remoteContainers count] % 4));
int remainder = [remoteContainers count] % 4;
switch (remainder) {
case 1: {
// Check to see the number of remaining containers left in the rest of the array. This dictates the way the final row must be constructed.
if ([remoteContainers objectAtIndex:currentStartRangeIndex]) {
NSDictionary *cellData = [NSDictionary dictionaryWithObjectsAndKeys:[remoteContainers objectAtIndex:rightIndex], @"LEFT_CONTAINER", @"EMPTY_CELL", @"LEFT_MIDDLE_CONTAINER", @"EMPTY_CELL", @"RIGHT_MIDDLE_CONTAINER", @"EMPTY_CELL", @"RIGHT_CONTAINER", nil];
[assetTableCell populateCellData:cellData];
}
}
break;
case 2: {
// There are two elements at the end of the array.
NSDictionary *cellData = [NSDictionary dictionaryWithObjectsAndKeys:[remoteContainers objectAtIndex:rightIndex], @"LEFT_CONTAINER", [remoteContainers objectAtIndex:rightMiddleIndex], @"LEFT_MIDDLE_CONTAINER", @"EMPTY_CELL", @"RIGHT_MIDDLE_CONTAINER", @"EMPTY_CELL", @"RIGHT_CONTAINER", nil];

[assetTableCell populateCellData:cellData];
}
break;
default: {
DLog(@"Thought the array had more elements, however was unable to determine the number of elements remaining in array.");
}
break;
}
}
}
return assetTableCell;
