我有這個問題cellForRowAtIndexPath
不是由reloadingData
調用。我花了很多時間。我將xib文件dataSource
和delegate
連接到File's Owner
。任何想法是受歡迎的。的tableView reloadData不工作:的cellForRowAtIndexPath不叫
這是我的代碼:
*的cellForRowAtIndexPath*
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
//cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
cell.backgroundColor = [UIColor clearColor];
cell.selectionStyle = UITableViewCellSelectionStyleGray;
cell.backgroundView.opaque = NO;
//cell.alpha = 0.65;
cell.textLabel.backgroundColor = [UIColor clearColor];
cell.textLabel.opaque = NO;
cell.textLabel.textColor = [UIColor whiteColor];
cell.textLabel.highlightedTextColor = [UIColor whiteColor];
cell.textLabel.font = [UIFont boldSystemFontOfSize:18];
cell.detailTextLabel.backgroundColor = [UIColor clearColor];
cell.detailTextLabel.opaque = NO;
cell.detailTextLabel.textColor = [UIColor whiteColor];
cell.detailTextLabel.highlightedTextColor = [UIColor whiteColor];
cell.detailTextLabel.font = [UIFont systemFontOfSize:14];
NSString *temp = [distanceArray objectAtIndex:indexPath.row];
if([checkMarkArray count] != 0){
NSString *checkString = [checkMarkArray objectAtIndex:0];
NSLog(@" checkString %@",checkString);
if ([temp isEqualToString:checkString ]) {
cell.accessoryView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"checked.png"]] autorelease];
}
else
{
cell.accessoryView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"unchecked.png"]] autorelease];
}
}
}
// Set up the cell...
[[cell textLabel] setText: [distanceArray objectAtIndex:indexPath.row]] ;
return cell;
}
didSelectRowAtIndexPath方法* ***
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];
cellText = selectedCell.textLabel.text;
NSLog(@"%@",cellText);
[checkMarkArray removeAllObjects];
if([[tableViewDistance cellForRowAtIndexPath:indexPath] accessoryType] == UITableViewCellAccessoryCheckmark)
{
//global array to store selected object
[checkMarkArray removeObject:[distanceArray objectAtIndex:indexPath.row]];
NSLog(@"array %@",checkMarkArray);
[tableViewDistance cellForRowAtIndexPath:indexPath].accessoryView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"unchecked.png"]] autorelease];
[[tableViewDistance cellForRowAtIndexPath:indexPath] setAccessoryType:UITableViewCellAccessoryNone];
[self.tableViewDistance reloadData];
}
else
{
[checkMarkArray addObject:[distanceArray objectAtIndex:indexPath.row]];
NSLog(@"array again %@",checkMarkArray);
[tableViewDistance cellForRowAtIndexPath:indexPath].accessoryView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"checked.png"]] autorelease];
[[tableViewDistance cellForRowAtIndexPath:indexPath] setAccessoryType:UITableViewCellAccessoryCheckmark];
[self.tableViewDistance reloadData];
}
tableViewDistance.delegate = self;
tableViewDistance.dataSource = self;
[self.tableViewDistance reloadData];
}
* viewDidLoad中 ** *
- (void)viewDidLoad
{
distanceArray= [[NSMutableArray alloc] initWithObjects:@"20 Kilomètres", @"40 Kilomètres", @"60 Kilomètres",@"80 Kilomètres",nil];
NSLog(@"distance %@",distanceArray);
tableViewDistance.backgroundColor=[UIColor clearColor];
checkMarkArray = [[NSMutableArray alloc] init];
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}
你是什麼意思,它不reloadData,什麼時候?既然你在viewDidLoad中設置了所有的設置,無論如何這隻會被調用一次(通常)。只有ViewDidAppear或viewWillAppear被多次調用。你有修改陣列嗎?你能澄清一下嗎? – user387184
我需要重新加載tableview後,我選擇了一排,因爲我需要一次只有一個選擇行 – Gabrielle
