iphone - 通过触摸内部激活uitableview

Question

我已禁用我的桌面 View

[self.tableView setScrollEnabled:NO];

[self.tableView setAllowsSelection:NO];

我想单击表格中的任意位置以重新激活表格。我可以这样做吗？

您可以使用UITapGestureRecognizer如前所述:

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(showTable:)];
[tapGesture setNumberOfTapsRequired:1];
[self.tableView addGestureRecognizer: tapGesture];
[tapGesture release];

和 Action

-(void) showTable:(UITapGestureRecognizer *)recognizer {
    if (recognizer.state == UIGestureRecognizerStateEnded) {
        UIView *table=recognizer.view;
        if ([table isKindOfClass: [UITableView class]]) {
            UITableView *tab=(UITableView *)table;
            if (![tab isScrollEnabled]) {
                [tab setScrollEnabled:YES];
                [tab setAllowsSelection:YES];
            }
        }
    }
}

(未测试)希望这会有所帮助。
