问题 I am having a problem with my UITableView in iOS7. Initially, the data loads in just fine, and I get output in my console that proves that the cells are speaking to the data source correctly, but as soon as I tap anywhere on the table, the cells disappear and the table goes blank . The height of the cells in the empty UITableView seem to be honoring the height my custom prototype cell (410px), but all the data in the cells vanish, and the empty table view acts like it only has one cell in it

问题 In previous versions of Interface Builder, when I want to lazy load views programatically, I would do something like: self.customView = [[NSBundle mainBundle] loadNibNamed:@"CustomView" owner:nil]; If I understand correctly, this was the proper way to do it. There does not seem to be a way to do this with storyboards, as there is no way to add a view into the storyboard itself(without being part of a view controller). I have a view controller that manages multiple views. I do not want them

问题 I'm updating my Calculator app to use new dynamically sized buttons and having a problem with the constraints. The contains should work fine as far as I can tell, but Xcode complains about misplaced views. The values it gives for the misplaced views are not proper and if I try to fix them, then it just causes more views to be "misplaced."
