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];
}
