iOS之有关视图偏移的问题

1.=========

 if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {

        self.edgesForExtendedLayout = UIRectEdgeNone;

        self.automaticallyAdjustsScrollViewInsets = NO;//设置scrollview不自动滚动

    }

 if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {

[self.tableView setSeparatorInset:UIEdgeInsetsZero];

}

if ([self.tableView respondsToSelector:@selector(setLayoutMargins:)]) {

[self.tableView setLayoutMargins:UIEdgeInsetsZero];

}

然后在UITableView的代理方法中加入以下代码

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

{

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

[cell setSeparatorInset:UIEdgeInsetsZero];

}

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

[cell setLayoutMargins:UIEdgeInsetsZero];

}

}
