Question

我正在尝试在编辑UITableView时更改自定义UITableViewCell内容的缩进（即图像，按钮和标签）。

我尝试像这样更改单元格的缩进宽度和级别

[cellToCustomize setIndentationLevel:1];
[cellToCustomize setIndentationWidth:20];

它让我无处可去。

我也实现了

-(NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath

功能

再一次，没有。

我想增加缩进级别，让我们说......为双倍。

有人知道怎么做吗？

谢谢！

Answer 1

我的缩进没有出现编辑模式的问题，但我发现，我已将子视图添加到单元格而不是cell.contentView - 所有组件都应添加为cell.contentView的子视图< / strong>。

Answer 2

你重装电池了吗？请参阅UITableView文档中的以下方法：

- (void)reloadData
- (void)reloadRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:(UITableViewRowAnimation)animation

- (void)viewDidLoad
{
    [super viewDidLoad];
    arraylist = [[NSMutableArray alloc]init];
    array5 = [[NSMutableArray alloc]init];
    array1 = [[NSMutableArray alloc]init];
    objects = @[@"Medical Services In Chicago",@"Medical Services On Campus"];
    arrObjectValueChicago = @[@"Ronald McDonald® Children's Hospital of Loyola",@"Burn Centers",@"Gottlieb Hospitals"];
    array3 = [[NSMutableArray alloc]init ];
    for(int i = 0; i<[arrObjectValueChicago count];i++){
            dictList3 = [[NSDictionary alloc]initWithObjectsAndKeys:@"2",@"level",[arrObjectValueChicago objectAtIndex:i],@"name", nil];
         [array3 addObject:dictList3];
    }





    NSDictionary *dictList2 = [[NSDictionary alloc]initWithObjectsAndKeys:@"Hospitals",@"name",@"1",@"level",array3,@"Objects",nil];

        NSMutableArray *array2 = [[NSMutableArray alloc]initWithObjects:dictList2, nil];
    for (int i =0; i<[objects count]; i++) {
        dictionary =[[NSDictionary alloc]initWithObjectsAndKeys:[objects objectAtIndex:i],@"name",@"0",@"level",array2,@"Objects", nil];
            [array1 addObject:dictionary];

    }


//    arrObjectValueCampus = @[@"Cardinal Bernardin Cancer Center1",@"Center for Heart & Vascular Medicine2"];
//    level = @[@"0",@"1",@"2",@"3"];

//     NSDictionary *dictList2 = [[NSDictionary alloc]initWithObjectsAndKeys:@"Hospitals",@"name",@"1",@"level",dictList3,@"Objects",nil];
//    NSDictionary *dictList1 = [[NSDictionary alloc]initWithObjectsAndKeys:@"0",@"level",@"Medical Services In Chicago",@"name",dictList2,@"Objects",nil];
    dictList = [[NSDictionary alloc]initWithObjectsAndKeys:array1,@"Objects", nil];

   NSLog(@"Dictionary :: %@",dictList);
     //   [arraylist addObject:[dictList valueForKey:@"Objects"]];
    arrayOriginal = [dictList valueForKey:@"Objects"];
    [arraylist addObjectsFromArray:arrayOriginal];
        }
