我有一个自定义表格视图。我想将表格视图单元格作为 pramater 传递给一个函数。我正在使用 [cell.btnImages performSelector]。单击照片按钮时,它应该将图像加载到相应的表格视图单元格中。是否可能?下面是代码。单击图像按钮时。我需要将单元格作为参数传递...
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"IpadTableViewCell";
IPadTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"IpadTableViewCell" owner:nil options:nil];
for (id currentObject in topLevelObjects)
{
if ([currentObject isKindOfClass:[IPadTableViewCell class]])
{
cell = (IPadTableViewCell *)currentObject;
}
}
}
[cell.btnImages performSelector:@selector(imageButtonClicked:) onThread:nil withObject:cell waitUntilDone:nil];
return cell;
}
-(void)imageButtonClicked:(IPadTableViewCell *)tblCell
{
// opne image select dialog
CGFloat prevButtonXPosition = 17, pageButtonXPosition, pageButtonWidth = 120, pageButtonHeight = 130;
for (NSInteger i =1; i<= 9; i++) {
pageButtonXPosition = prevButtonXPosition ;
prevButtonXPosition = pageButtonXPosition + pageButtonWidth;
UIButton *pageButton = [UIButton buttonWithType:UIButtonTypeCustom];
[pageButton addTarget:self action:@selector(onClickImage:) forControlEvents:UIControlEventTouchUpInside];
[pageButton setFrame:CGRectMake(pageButtonXPosition, 5, pageButtonWidth, pageButtonHeight)];
[pageButton setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:@"%i.png",i]] forState:UIControlStateNormal];
[pageButton setTag:i];
[cell.scrollView addSubview:pageButton];
}
UIButton *add=[UIButton buttonWithType:UIButtonTypeCustom];
[add addTarget:self action:@selector(onClickAdd:) forControlEvents:UIControlEventTouchUpInside];
[add setFrame:CGRectMake(prevButtonXPosition, 20, 80, 80)];
[add setBackgroundImage:[UIImage imageNamed:@"last.jpeg"] forState:UIControlStateNormal];
[add setTag:0];
[cell.scrollView addSubview:add];
[cell.scrollView setContentSize:CGSizeMake(prevButtonXPosition +80, 40)];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
