我必须创建一个多个按钮所在的单元格。这里tableview是可扩展和折叠的,部分的数量和部分中的行数是动态的。
我希望以这种方式执行任务
在我想要的每一行中只剩下4个任务n剩余任务将显示在下一行。但我的问题是,如果我只有13个任务而不是它包含4行,则在第1和第3行它包含4个任务,在最后一行它只包含1个任务但我不能这样它也不会改变文本任务。
这是我的代码。
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if ([self tableView:tableView canCollapseSection:section])
{
if ([expandedSections containsIndex:section])
{
objePro = [appDelegate.array_proj objectAtIndex:section];
rowcount = [objePro.arr_task count] + 1;
NSLog(@"rowcount %d",rowcount);
if (rowcount < 4)
return 2;
else
{
if (rowcount % 4)
{
NSLog(@"odd: %d",rowcount/4 + 2);
return rowcount/4 + 2;
}
else
{
NSLog(@"even: %d",rowcount/4);
return rowcount/4;
}
}
}
}
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] ;
}
cell.backgroundColor = [UIColor clearColor];
if ([self tableView:tableView canCollapseSection:indexPath.section])
{
if (!indexPath.row)
{
cell.textLabel.textColor = [UIColor whiteColor];
UIImageView *backgroundView = [[UIImageView alloc] initWithFrame:CGRectZero];
cell.backgroundView = backgroundView;
backgroundView.image = [UIImage imageNamed:@"prjctcell_bg.png"];
objePro = [appDelegate.array_proj objectAtIndex:indexPath.section];
cell.textLabel.text = objePro.projctname;
if ([expandedSections containsIndex:indexPath.section])
cell.accessoryView = [DTCustomColoredAccessory accessoryWithColor:[UIColor blackColor] type:DTCustomColoredAccessoryTypeUp];
else
cell.accessoryView = [DTCustomColoredAccessory accessoryWithColor:[UIColor blackColor] type:DTCustomColoredAccessoryTypeDown];
}
else
{
// all other rows
cell.accessoryView = nil;
j=4;
for (k = 0; k<4; k++)
{
NSLog(@"k %d",k);
btnexpand = [[UIButton alloc] init];
btnexpand = [UIButton buttonWithType:UIButtonTypeCustom];
btnexpand.frame = CGRectMake(j, 5, 80, 40);
btnexpand.backgroundColor = [UIColor clearColor];
[btnexpand setTitleColor:[UIColor colorWithRed:53.0/255 green:53.0/255 blue:53.0/255 alpha:1.0] forState:UIControlStateNormal];
btnexpand.titleLabel.font = [UIFont boldSystemFontOfSize:14];
[btnexpand setTitle:[NSString stringWithFormat:@"Step %d",[[[[appDelegate.array_proj objectAtIndex:indexPath.section] arr_task] objectAtIndex:indexPath.row - 1] taskid]] forState:UIControlStateNormal];
NSLog(@"btn title: %@",btnexpand.titleLabel.text);
[btnexpand setBackgroundImage:[UIImage imageNamed:@"greenarrow.png"] forState:UIControlStateNormal];
[cell.contentView addSubview:btnexpand];
j= j+65;
}
}
}
return cell;
}
请帮帮我。
答案 0 :(得分:1)
在numberOfRowsInSection
rowcount = [objePro.arr_task count]; // Keep original count
if (rowcount % 4) // This means its not exact multiple of four
return rowcount/4 + 2;
else
return rowcount + 1;
在cellForRowAtIndexPath
中if(indexpath.row == 0){
Your code for header line
}
else{
objePro = [appDelegate.array_proj objectAtIndex:section];
int rowcount = [objePro.arr_task count];
if(rowcount < 4){
for(int i = 0; i < 4; i++){
NSLog (@"%d", i+1);
}
}
else{
int iRow = rowcount / 4;
if (rowcount % 4){
for(int i = 0; i < 4; i++)
NSLog(@"Current Step %d", indexpath.row-1 + i);
}
else{
for(int i = 0; i < rowcount % 4; i++)
NSLog(@"Current Step %d", indexpath.row-1 + i);
}
}
}
这就是诀窍,你需要付出一些努力。希望我已经向你展示了一些方向。
