iOS 工作中遇到的问题 (二)

去掉tableViewHeader的黏性

(1)
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    if (scrollView == self.tableView)
    {
        CGFloat sectionHeaderHeight = 50; //sectionHeaderHeight
        if (scrollView.contentOffset.y <=     sectionHeaderHeight && scrollView.contentOffset.y >= 0) {
            scrollView.contentInset = UIEdgeInsetsMake(-scrollView.contentOffset.y, 0, 0, 0);
        } else if (scrollView.contentOffset.y >= sectionHeaderHeight) {
            scrollView.contentInset = UIEdgeInsetsMake(-sectionHeaderHeight, 0, 0, 0);
        }
    }
}
(2)分组改成分组模式
_tableView = [[UITableView alloc]initWithFrame:CGRectZero style:UITableViewStyleGrouped];
这个时候顶部和底部都会有一段空白,加上下面代码即可
self.tableView.tableFooterView = [[UIView alloc]init];
self.tableView.tableHeaderView = [[UIView alloc]init];
- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
    return 0.01f;
}
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
    return 0.01f;
}

键盘管理框架IQKeyboardManager

IQKeyboardManager *manager = [IQKeyboardManager sharedManager];
manager.enable = YES;
manager.shouldResignOnTouchOutside = YES;
manager.shouldToolbarUsesTextFieldTintColor = YES;
manager.enableAutoToolbar = NO;
manager.keyboardDistanceFromTextField = 400;

tableView 滚动到指定cell

NSIndexPath  *indexPath = [NSIndexPath indexPathForRow:lastSelectRow inSection:0];  
        [self.tableView scrollToRowAtIndexPath:indexPath  
                              atScrollPosition:UITableViewScrollPositionBottom animated:YES]; 

解决崩溃:
[self.tableView setContentOffset:CGPointMake(0.0, (self.lastSelectRow ) *44.0) animated:YES];  

tableView滚动的时候退出键盘

self.tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag;
