我创建这是越来越使用数组填充的详细披露按钮....然而accessoryButtonTappedForRowWithIndexPath:功能不被称为我的课.这是一个TableviewDelegate
和TableviewDatasource
委托.
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath{
NSLog(@"reaching accessoryButtonTappedForRowWithIndexPath:");
[self performSegueWithIdentifier:@"modaltodetails" sender:[self.eventsTable cellForRowAtIndexPath:indexPath]];
}

NSLog没有打印到控制台,这使我相信函数没有被调用...这当然是我选择一个单元格.下面的屏幕截图显示了我如何设置单元格.
我有一个奇怪的问题.我收到此错误:

好的,我确保将ViewController设置为dataSource和Delegate.我已将UITableViewDelegate和UITableViewDataSource添加到<> thingies中.

我有一些EditText views
我想在左边设置图像的地方,setCompoundDrawablesWithIntrinsicBounds

有谁知道为什么会这样?

所以基本上我需要能够在块运行完成后运行segue.我有一个块,它可以执行一些JSON操作,我需要知道它何时运行完毕.
我有一个名为json_queue的队列.
jsonQueue = dispatch_queue_create("com.jaboston.jsonQueue", NULL);

dispatch_async(jsonQueue, ^{

它不会让我执行这一行:"[self performSegueWithIdentifier:@"modaltomenu"sender:self];"

我在哪里可以检查线程何时完成其脏工作,以便我可以调用segue?
