自定義tableview單元格

我正在創建一個自定義UItableviewcell。我有標籤和圖像（複選標記）。點擊該圖片後，特定的單元格會被檢查，我做了多次選擇，但現在我想一次選擇一個單元格。自定義tableview單元格

這是我的代碼：

iphone

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *CellIdentifier = @"Cell"; 
    BOOL checkButtonPressed=FALSE; 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (cell == nil) { 
     cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 

    } 

    UIImage *image = (checkButtonPressed) ? [UIImage imageNamed:@"checked.png"] : [UIImage imageNamed:@"unchecked.png"]; 

    UIButton *checkButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    CGRect frame = CGRectMake(0.0, 0.0, image.size.width, image.size.height); 
    checkButton.frame = frame; // match the button's size with the image size 

    [checkButton setBackgroundImage:image forState:UIControlStateNormal]; 



    [checkButton addTarget:self action:@selector(checkButtonTapped:event:) forControlEvents:UIControlEventTouchUpInside]; 
    //cell.imageView.image = [UIImage imageNamed:@"unchecked.png"]; 
    cell.textLabel.adjustsFontSizeToFitWidth = YES; 


    for (int ii=0; ii<=[checkedArr count]; ii++) { 
     cell.textLabel.text =[dataArray objectAtIndex:ii]; 
    } 

    //cell.backgroundColor = [UIColor clearColor]; 
    cell.accessoryView = checkButton; 
    [cellArr addObject:cell]; 
    [checkedArr addObject:[NSNumber numberWithBool:FALSE]]; 

    return cell; 



} 

- (void)checkButtonTapped:(id)sender event:(id)event 
{ 

    NSSet *touches = [event allTouches]; 
    UITouch *touch = [touches anyObject]; 
    CGPoint currentTouchPosition = [touch locationInView:tableView]; 
    NSIndexPath *indexPath = [tableView indexPathForRowAtPoint: currentTouchPosition]; 
    NSLog(@"val %d",[checkedArr count]); 
    if (indexPath != nil && iChecked == 0) 
    { 
     [self tableView:tableView accessoryButtonTappedForRowWithIndexPath: indexPath]; 
    } 
} 


- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath 
{ 
    NSLog(@"in accessoryButtonTappedForRowWithIndexPath %d",indexPath.row); 

    BOOL checked = [[checkedArr objectAtIndex:indexPath.row] boolValue]; 


    [checkedArr replaceObjectAtIndex:indexPath.row withObject:[NSNumber numberWithBool:!checked]]; 

    UITableViewCell *cell = [cellArr objectAtIndex:indexPath.row]; 
    UIButton *button = (UIButton *)cell.accessoryView; 

    UIImage *newImage = (checked) ? [UIImage imageNamed:@"unchecked.png"] : [UIImage imageNamed:@"checked.png"]; 
    [button setBackgroundImage:newImage forState:UIControlStateNormal]; 
    cell.accessoryView = button; 
    iChecked = 0; 



}

同意，現在不可能得到任何幫助...... – Joetjah 2011-05-10 09:48:07

喜的朋友你要做的就像下面單複選標記..

(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath{ 
if (curSelRowIndex == indexPath.row) { 
cell.accessoryType = UITableViewCellAccessoryCheckmark;} 
else { 
cell.accessoryType = UITableViewCellAccessoryNone;} 
return cell; 
} 

(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 
curSelRowIndex = indexPath.row; 
[tblHistory reloadData]; 
}
