UITableview边框隐藏部分单元格

Question

我正在尝试使用border，section header和cell创建UITableview。我正在使用xib文件。使用xib文件创建UITableview和单元格，其中“viewForHeaderInSection”用于节标题，但是当我尝试将边框设置为UITableview时，它隐藏了它后面的节和单元格。

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.

self.tableView.delegate = (id) self;
self.tableView.dataSource = (id) self;
self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
self.tableView.layer.borderWidth = 20.0;
self.tableView.layer.borderColor = [UIColor colorWithRed:204/255.0 green:204/255.0 blue:204/255.0 alpha:1.0f].CGColor;

}

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{

NSDictionary *dict = [[NSDictionary alloc] initWithDictionary:[self.array objectAtIndex:section] copyItems:YES];

UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 5, tableView.frame.size.width, 50)];
view.backgroundColor = [UIColor colorWithRed:81/255.0 green:190/255.0 blue: 168/255.0 alpha:1.0f];

UIView *seperatoreView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 10)];
seperatoreView.backgroundColor = [UIColor colorWithRed:204/255.0 green:204/255.0 blue:204/255.0 alpha:1.0f];

[view addSubview:seperatoreView];

UILabel *numberLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 100, 30)];
numberLabel.backgroundColor = [UIColor clearColor];
numberLabel.text = [NSString stringWithFormat:@"%@",[dict objectForKey:@"key"]];
numberLabel.textColor = [UIColor whiteColor];
[numberLabel setFont:[UIFont boldSystemFontOfSize:17.0f]];

[view addSubview:numberLabel];

NSDateFormatter *formate = [[NSDateFormatter alloc] init];
[formate setDateFormat:@"yyyy-MM-dd"];
NSDate *SDate = [formate dateFromString:[dict objectForKey:@"sDateKey"]];
NSDate *EDate = [formate dateFromString:[dict objectForKey:@"eDateKey"]];

[formate setDateFormat:@"MMM d"];
NSString *StartDateStr = [formate stringFromDate:SDate];
NSString *EndDateStr = [formate stringFromDate:EDate];

if([StartDateStr isEqual:[NSNull null]]){
    StartDateStr = @"";

}
if([EndDateStr isEqual:[NSNull null]]){

    EndDateStr = @"";
}

UILabel *weekDateLabel = [[UILabel alloc] initWithFrame:CGRectMake(view.frame.size.width-140, 10, 150, 30)];
weekDateLabel.backgroundColor = [UIColor clearColor];
weekDateLabel.text = [NSString stringWithFormat:@"%@ - %@",StartDateStr,EndDateStr];
weekDateLabel.textColor = [UIColor whiteColor];
[weekDateLabel setFont:[UIFont boldSystemFontOfSize:17.0f]];

[view addSubview:weekDateLabel];

return view;
}

我想要UITableview边框但是有完整的标题和单元格，有谁知道如何实现它？

Answer 1

您可以尝试伪造您想要的行为。您不必使用边框，而是必须在UIView的所有四个角上添加UITableViewCell，并使用每个UIView的适当高度/宽度和灰色作为背景颜色。现在，在您的cellForRow中，您必须检查单元格的位置，并根据隐藏/取消隐藏顶部和底部UIView（左侧和右侧UIView始终可见） 。像这样：

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

    .....
    if(indexPath.row == 0){

        [cell.topBorderView setHidden: NO];
        [cell.bottomBorderView setHidden: YES];

    }else if(indexPath.row == dataSourceArray.count - 1){

        [cell.topBorderView setHidden: YES];
        [cell.bottomBorderView setHidden: NO];

    }else{

        [cell.topBorderView setHidden: YES];
        [cell.bottomBorderView setHidden: YES];
    }

    return cell;
} 

当然，删除整个UITableView

上的边框

你的borderWidth太多了，你需要添加的是 用于Cell中的个人资料图片 你应该设置配置文件图片imageView左边增加边框宽度。

let margin_left =  BorderWidth  + space_from_left. 
ProfileImageView.frame = CGRect(x: margin_left,y:Y,width:yourRequiredWidth,  height:requiredHeight)

和节标题标签相同

 let margin_left =  BorderWidth  + space_from_left. 
    headerLabel.frame = CGRect(x: margin_left,y:Y, width:yourRequiredWidth,  height:requiredHeight)
