What happens when you call UItableview's reload twice
ios,objective-c,uitableview,tableview
Your question can't happen. All reloading is done on the main thread. The call to reloadData doesn't return until the reload is complete. So you can't call it a second time while the previous reload is still running. It's a non-issue. And your question also implies a misunderstanding of how...

How can I centre both vertically and horizontally in a UILabel after resizing the text to fit width (1 line label)?

You are setting the label as a one-line label (by default) and setting its height at a fixed height, thus fixing its position: UILabel *numberLabel = [[UILabel alloc] initWithFrame:CGRectMake(30, 0, 60, 40)]; Thus, you are getting a constant baseline position for all your labels, regardless of the font size.
