以适当的格式显示UITableView [英] Displaying UITableView in proper format
本文介绍了以适当的格式显示UITableView的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有以下代码从URL获取数据，将其存储在数组中，并在表中显示。
我遇到了一些与提取相关的问题，并且已经解决了这个问题，请点击此处点击此处
现在问题是数据以不理想的方式显示在表中。
I have the following code to fetch the data from URL, store it in arrays, and display it inside the table. I had some issue related to fetching and that is solved on SO Click here Now the issue is data is displayed in the table in a manner which is not the ideal one.
当我运行下面的代码时，我得到了这个输出。阴影灰色部分是我主要担心的问题。
当我尝试通过设计视图在该灰色阴影区域中插入任何元素说按钮时，它会被表重叠。
如果我改变
When I run the below code, I get this output. That shaded grey portion is my main concern. When I try to insert any element say button in that grey shaded area through design view, it gets overlapped by table. If I change
aTableView = [[UITableView alloc] initWithFrame：[[UIScreen mainScreen] applicationFrame] style：UITableViewStyleGrouped];
with
aTableView = [[UITableView alloc] initWithFrame：[[UIScreen mainScreen] applicationFrame] style：UITableViewStylePlained];
我得到没有灰色阴影的表格输出但是太简单了。
I get the table output without the grey shadow but it's way too simple.

推荐答案
如果您的问题是要从您的分组表视图中删除lightgrey区域，那么您可以通过将此添加到代码中来删除阴影灰色区域：
If your problem is to remove the lightgrey area from your groupedtableview, then you can remove the shaded grey area by adding this to your code:
if ([myTable respondsToSelector:@selector(backgroundView)]) {
myTable.backgroundView = nil;
}
只有iPad才有这个问题，只有iPad才能使用groupTableViewStyle。
It's an issue that only iPad has with groupedTableViewStyle.
