我正在尝试在UITableView中为分隔符设置自定义插件。这是我的viewDidLoad代码
- (void)viewDidLoad {
[super viewDidLoad];
[self.tableView registerClass:[ChatTableCell class] forCellReuseIdentifier:@"ChatCell"];
[self.tableView setSeparatorInset:UIEdgeInsetsMake(0, 65, 0, 0)];
}
单元格分隔符插图无法正常工作,如图所示。它适用于某些细胞而不适用于其他细胞。我在这做错了什么?
这是我的viewcontroller.m文件的样子

答案 0 :(得分:7)
在我的所有解决方法之后,现在已经在ios 7和8中进行了测试。
-(void)viewDidLayoutSubviews
{
[customTableview setSeparatorInset:UIEdgeInsetsZero];
}
-(void)tableView:(UITableView *)tableView willDisplayCell:(customCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
if ([tableView respondsToSelector:@selector(setSeparatorInset:)]){
[tableView setSeparatorInset:UIEdgeInsetsZero];
}
if ([tableView respondsToSelector:@selector(setLayoutMargins:)]) {
[tableView setLayoutMargins:UIEdgeInsetsZero]; // ios 8 newly added
}
if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
[cell setLayoutMargins:UIEdgeInsetsZero];
}
}
