自定义UITableView的Seperator

在默认配置中，UITableView的Cell之间的Seperator左边总是空出一块，即使在Storyboard中设置为0 ，也没有效果

需要在代码中进行配置，在ViewController中实现如下方法

-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath

{

// Remove seperator inset

if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {

[cell setSeparatorInset:UIEdgeInsetsZero];

}

// Prevent the cell from inheriting the Table View's margin settings

if ([cell respondsToSelector:@selector(setPreservesSuperviewLayoutMargins:)]) {

[cell setPreservesSuperviewLayoutMargins:NO];

}

// Explictly set your cell's layout margins

if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {

[cell setLayoutMargins:UIEdgeInsetsZero];

}

如果所有的界面都是如此风格，也可以通过UIAppearance 统一配置

// iOS 7:

[[UITableView appearance] setSeparatorStyle:UITableViewCellSeparatorStyleSingleLine];

[[UITableView appearance] setSeparatorInset:UIEdgeInsetsZero];

[[UITableViewCell appearance] setSeparatorInset:UIEdgeInsetsZero];

// iOS 8:

if ([UITableView instancesRespondToSelector:@selector(setLayoutMargins:)]) {

[[UITableView appearance] setLayoutMargins:UIEdgeInsetsZero];

[[UITableViewCell appearance] setLayoutMargins:UIEdgeInsetsZero];

[[UITableViewCell appearance] setPreservesSuperviewLayoutMargins:NO];

}
