回答1:

for static cell.. all of these methods .. must be setup in the storyboard file..

so.. click on storyboard file / Table view / Separator "none" / and choose desired color..

回答2:

UITableViewCell contentView's underlying CALayer

Firstly import QuartzCore

#import <QuartzCore/QuartzCore.h>

Add this in cellForRowAtIndexPath in UITableView delegate method

[cell.contentView.layer setBorderColor:[UIColor blackColor].CGColor]; //any color u want to....
[cell.contentView.layer setBorderWidth:2.0f]; //set its width here

EDIT :Use this property according to requirement if tableview is static:

separatorStyle  property
separatorColor  property
backgroundView  property

In CellForRowAtIndexPath, try this (after you init your cell) :

cell.layer.borderColor = [UIColor blackColor].CGColor;

Of course you can change blackColor to any other UIColor.

You can also do :

cell.layer.borderWidth = 0;

If you just wan to hide it.

the following code will change the separator color, which means that it will change the separator line between the cell and the border itself.

try this to change it to black:

tableView.separatorColor = [UIColor blackColor];

or to remove it:

tableView.separatorColor = [UIColor clearColor];
