UITableView

1：创建一个简单的TableView

- (void)viewDidLoad
{
    [super viewDidLoad];
	// Do any additional setup after loading the view, typically from a nib.
    self.myTableList = [[NSMutableArray alloc] initWithCapacity:0];
    
    NSMutableArray *myArray = [[NSMutableArray alloc] initWithObjects:@"00", @"11", @"22", @"33", @"44", @"55", @"66", @"77", @"88", @"99",  nil];
    self.myTableList = myArray;
    
    CGRect rect = [[UIScreen mainScreen] bounds];
    self.myTableView = [[UITableView alloc] initWithFrame:CGRectMake(rect.origin.x, rect.origin.y, rect.size.width, rect.size.height-20) style:UITableViewStyleGrouped];
    self.myTableView.delegate = self;
    self.myTableView.dataSource = self;
    //改变背景颜色
    self.myTableView.backgroundView = nil;
    self.myTableView.backgroundColor = [UIColor lightGrayColor];
    [self.view addSubview:self.myTableView];
}
#pragma mark TableViewDelegate
//多少section
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 2;
}
//section头内容
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
    return @"";
}
//返回section中row行数
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [self.myTableList count];
}
//返回row的高度
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 44;
}
//
- (UITableViewCell *)tableView: (UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *) indexPath
{
    static NSString *tableCellIdentifier1 = @"tableCellIdentifier1";
    static NSString *tableCellIdentifier2 = @"tableCellIdentifier2";
    
    NSInteger nRow = [indexPath row];
    //不通过xib加载cell
    if (indexPath.section == 0) {
        UITableViewCell *pCell = [tableView dequeueReusableCellWithIdentifier:tableCellIdentifier1];
        if (pCell == nil) {
            pCell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:tableCellIdentifier1];
        }
        
        pCell.textLabel.text = [self.myTableList objectAtIndex:nRow];
        pCell.imageView.image = [UIImage imageNamed:@"test.png"];
        //cell右侧的显示样式
        pCell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
        if (nRow == 0) {
            //当为UITableViewCellSelectionStyleNone点击时不显示颜色变化
            pCell.selectionStyle = UITableViewCellSelectionStyleNone;
        } else if (nRow == 1) {
            pCell.selectionStyle = UITableViewCellSelectionStyleNone;
            //改变cell背景颜色
            pCell.textLabel.text = @"";
            UIView *backgrdView = [[UIView alloc] initWithFrame:pCell.frame];
            backgrdView.backgroundColor = [UIColor redColor];
            pCell.backgroundView = backgrdView;
        }
        
        return pCell;
    } else if (indexPath.section == 1) {  //通过xib加载cell
        OAApplyCell *pCell = [tableView dequeueReusableCellWithIdentifier:tableCellIdentifier2];
        if (!pCell) {
            NSArray *objects = [[NSBundle mainBundle] loadNibNamed:@"OAApplyCell" owner:self options:nil];
            for (NSObject *o in objects) {
                if ([o isKindOfClass:[OAApplyCell class]]) {
                    pCell = (OAApplyCell *)o;
                    break;
                }
            }
        }
        pCell.titleLab.text = [self.myTableList objectAtIndex:nRow];
        
        return pCell;
    }

    return nil;
}

2：获取tableView中cell

- (void)getOneCell
{
    NSInteger nRow = 0;
    UITableViewCell *cell = [self.myTableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:nRow inSection:1]];
    OAApplyCell *pCell = (OAApplyCell *)cell;
    pCell.titleLab.text = @"test";
}

3：tableView中cell向右移，非xib加载cel时 pCell.textLabel.text才起作用

-(NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath{
    NSUInteger row = [indexPath row];
    return row;
}

4：禁止tableView中cell点击响应

//判断选中的行（阻止选中第一行）
-(NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSUInteger row = [indexPath row];
    if (row == 0)
        return nil;
    
    return indexPath;
}

5：滑动删除cell

//划动cell是否出现del按钮
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
    return YES;
}
//删除Cell
- (void)tableView:(UITableView *)tableView
commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSUInteger nRow = [indexPath row];
    [self.myTableList removeObjectAtIndex:nRow];
    [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]
                     withRowAnimation:UITableViewRowAnimationFade];
}

6：移动cell 这边需要设置    [ self . myTableView setEditing : YES animated : YES ]; 才可以编辑移动

//移动cell
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView
           editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
    return UITableViewCellEditingStyleNone;
}
- (BOOL)tableView:(UITableView *)tableView
canMoveRowAtIndexPath:(NSIndexPath *)indexPath {
    return YES;
}
- (void)tableView:(UITableView *)tableView
moveRowAtIndexPath:(NSIndexPath *)fromIndexPath
      toIndexPath:(NSIndexPath *)toIndexPath
{
    //    NSUInteger fromRow = [fromIndexPath row];
    //    NSUInteger toRow = [toIndexPath row];
    //
    //    id object = [[self.myTableList objectAtIndex:fromRow] retain];
    //    [self.myTableList removeObjectAtIndex:fromRow];
    //    [self.myTableList insertObject:object atIndex:toRow];
    //    [object release];
    
    id object = [self.myTableList objectAtIndex:fromIndexPath.row];
    [self.myTableList removeObjectAtIndex:fromIndexPath.row];
    [self.myTableList insertObject:object atIndex:toIndexPath.row];
}

7：移动cell时的委托提示

//可以用来当移动某个Cell上提示
- (NSIndexPath *)tableView:(UITableView *)tableView
targetIndexPathForMoveFromRowAtIndexPath:(NSIndexPath *)sourceIndexPath
       toProposedIndexPath:(NSIndexPath *)proposedDestinationIndexPath
{
    if (proposedDestinationIndexPath.section != sourceIndexPath.section)
    {
        //keep cell where it was...
        NSLog(@"YES");
        return sourceIndexPath;
    } else {
    //ok to move cell to proposed path...
    NSLog(@"NO");
    return proposedDestinationIndexPath;
    }
}

8：滑动删除时防止被Delegate按钮挡住

//滑动删除，,titleLab左移，防止被delete按钮盖住。
- (void)tableView:(UITableView *)tableView willBeginEditingRowAtIndexPath:(NSIndexPath*)indexPath
{
    OAApplyCell * cell = (OAApplyCell *)[tableView cellForRowAtIndexPath:indexPath];
    cell.titleLab.frame = CGRectMake(30, 34, 220, 18);
}
//恢复titleLab宽度
- (void)tableView:(UITableView *)tableView didEndEditingRowAtIndexPath:(NSIndexPath*)indexPath
{
    OAApplyCell * cell = (OAApplyCell *)[tableView cellForRowAtIndexPath:indexPath];
    cell.titleLab.frame = CGRectMake(30, 34, 250, 18);
}

9：设置cell右边的按钮并响应事件

        //设置Cell右边按钮并响应的事件
        UIImage *buttonUpImage = [UIImage imageNamed:@"01.png"];
        UIImage *buttonDownImage = [UIImage imageNamed:@"02.png"];
        UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
        button.frame = CGRectMake(0.0, 0.0, 100, 40);
        [button setBackgroundImage:buttonUpImage forState:UIControlStateNormal];
        [button setBackgroundImage:buttonDownImage forState:UIControlStateHighlighted];
        [button setTitle:@"Done" forState:UIControlStateNormal];
        [button addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
        pCell.accessoryView = button;

10：设置编辑状态时cell内容不会缩进

//设置编辑状态时cell内容不会缩进
- (BOOL)tableView:(UITableView *)tableView shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath
{
    return NO;
}
