UITableView reloadData之前的reloadSections

Question

I have a standard UIViewController with a UITableView inside of it. I am trying to reloadSections; however, it is locking up my app. I've noticed that the very first time that I load data in the table and I call reloadSections, it locks up; however, if I call reloadData the FIRST time, and reloadSections after subsequent updates it works fine.

Is this the expected behavior?

I do not quite understand what you mean,but you can try this.

[CATransaction begin];  
[CATransaction setCompletionBlock:^{  
     [yourTable reloadData];  
}];  
[yourTable reloadSections:[[NSIndexSet alloc] initWithIndex:2] withRowAnimation:UITableViewRowAnimationAutomatic];
[CATransaction commit];

Hope this helps you.
