ios – UITableView setSeparatorInset无法正常工作

概述我试图在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.tabl 我试图在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)];}

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

解决方法 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];}}
