问题 I have a UITableView inside a UIView inside a UIScrollView. Problem: when i scroll/drag the tableview, the scrollview scrolls too. What i need is for the tableview not to pass the scroll to the scrollview. Also i need to be able to use the scrollview when i scroll it directly. How can i do this? Cheers 回答1: I fixed it using "hitTest" on the tableview. - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event If the event originated within the tableview, i disable the parent's scrollview

问题 I'm using the Reachability class to detect wifi availability. There are some situations when an ipad will be connected to one wifi network,and a user will connect to another available wifi network. During these network transitions reachable->unreachable->reachable notifications are not generated. This connection change where the ip address of the ipad changes is what Im trying to listen for. Do notifications for local wifi connection changes exist or will I have to just poll my ip

问题 My view controllers need to send messages to a couple of model objects. How do I obtain references to these model objects inside the view controller? These model objects are "singletons" (in that there should only be one copy of them in the system at once) and they are used by multiple view controllers. So I can't instantiate them in the init method of each view controller. I can't use constructor injection as the runtime chooses the init method that gets used to create the view controller. I
