1.给tableView设置背景view UIImageView *backImageView=[[UIImageViewalloc]initWithFrame:self.view.bounds];
[backImageView setImage:[UIImageimageNamed:@ "liaotianbeijing" ]];
self.tableView.backgroundView=backImageView;
2.让cell透明 -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { MyCell *cell = [tableViewdequeueReusableCellWithIdentifier:@ "METext" forIndexPath:indexPath];
cell.backgroundColor=[UIColor clearColor]; //关键语句
[cell setCellInfo:dic]; //自定义类目方法
return cell;
} |
给tableView设置背景图片,但如果直接设置背景 backgroundView的话,背景图不会显示,原因是 tableView上的cell默认是不透明的颜色,所以解决方法是 让 cell透明即可。
给cell设置图片:
1
|
cell.imageView.image = [UIImage imageNamed:@ "childish_folder" ];

- ( void )tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{ NSLog(@ "userId是:%@" ,_userId);
NSLog(@ "长按的行号是:%d" ,[indexPath row]);
} |
NSInteger的输格式化输出是%ld:
1
|
NSString *number = [@ "NO." stringByAppendingString:[NSString stringWithFormat:@ "%ld:" , (indexPath.row + 1)]];
|
如果格式写成%d的话,Xcode会出现警告。
