我有一個UITableview與圖像按鈕。當點擊按鈕時，它將動態添加子視圖（表格視圖），如下圖所示的下拉列表。我無法選擇下拉列表中的第二個選項（表格視圖）。在iOS中：無法觸摸子視圖中的UITableview
問題是下拉高度超過了表格行，所以我無法選擇第二個選項。
任何人都有解決方案嗎？或任何想法顯示在UITableView下拉？
。
編輯：
這UITextField做工精細dropdown.but不是在UITableView的工作。
下拉代碼：
- (id)showDropDown:(UIButton *)b:(CGFloat *)height:(NSArray *)arr:(NSString *)direction {
btnSender = b;
animationDirection = direction;
self.table = (UIButton *)[super init];
if (self) {
// Initialization code

self.list = [NSArray arrayWithArray:arr];
if ([direction isEqualToString:@"up"]) {
self.frame = CGRectMake(btn.origin.x, btn.origin.y, btn.size.width, 0);
self.layer.shadowOffset = CGSizeMake(-5, -5);
}else if ([direction isEqualToString:@"down"]) {

self.layer.shadowOffset = CGSizeMake(-5, 5);
}

你可以分享添加下拉 – 2014-09-25 05:39:06
下拉代碼的代碼是共享的。 – Chidhambaram 2014-09-25 06:00:06
一段時間增加按鈕寬度。並且在那裏添加了按鈕。並且還分享了cellforrowatindex代碼的代碼。 – 2014-09-25 06:04:55
