Objective C: How to make background color of UITableView Consistent
提问by Zhen
I have been trying to set the background color of my table view but am facing an issue
我一直在尝试设置表格视图的背景颜色，但遇到了一个问题
This is what I am trying to do.
这就是我想要做的。
//Set background color of table view (translucent)
self.tableView.backgroundColor = [UIColor colorWithRed:0.0 green:0.2 blue:0.5 alpha:0.7];
//Set frame for tableview
[self.tableView setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height-self.picker.frame.size.height)];
After setting the table cells, I saw that there is an inconsistency in the alpha level around the table view cell (see screenshot below)
设置表格单元格后，我看到表格视图单元格周围的alpha级别存在不一致（见下面的截图）
Is there anyway to make the color / alpha level consistent for the background? (Note: I am not setting a background image, only color and alpha level)
有没有办法使背景的颜色/阿尔法级别保持一致？（注意：我没有设置背景图片，只有颜色和 alpha 级别）
Thanks!
谢谢！

I recently ran into this problem myself and think I found the solution
我最近自己遇到了这个问题，并认为我找到了解决方案
self.tableView.backgroundColor = [UIColor clearColor];
self.parentViewController.view.backgroundColor = [UIColor colorWithRed:0.0 green:0.2 blue:0.5 alpha:0.7];
Give that a shot, might need some massaging for your specific case (looks like you have some picture behind that translucent blue too).
试一试，可能需要针对您的特定情况进行一些按摩（看起来您在半透明蓝色后面也有一些图片）。

You need to make the background of the UITableView clear as well as set Opaque to FALSE
您需要使 UITableView 的背景清晰，并将 Opaque 设置为 FALSE
[self.tableView setBackgroundColor: [UIColor clearColor]];
[self.tableView setOpaque: NO];

All you need to do are 2 things:
所有你需要做的是两两件事：
E.g. A view has a table view in it.
In the XIBfile set the background of the UITableViewto clear color.
Set the background of the container view of the table view to the image you want.
例如，视图中有一个表视图。在XIB文件中将背景设置UITableView为清除颜色。将table view的container view的背景设置成你想要的图片。
self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"app_background.png"]];
If the ViewController is actually a TableViewControllerthen set:
如果 ViewController 实际上是一个TableViewControllerthen 设置：
self.parentViewController.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"app_background.png"]];
You can set the row background with inside the table view delegate (the view or tableview controller)
您可以在表视图委托（视图或表视图控制器）内部设置行背景
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
if ([indexPath row] % 2 == 0) {//248 G:192 B:100
[cell setBackgroundColor: [UIColor redColor]];
} else {
[cell setBackgroundColor: [UIColor colorWithPatternImage:[UIImage imageNamed:@"xyz.png"]]];
}
}
