问题
Basically, I want to create a button underneath a grouped table view, like contacts.app has to delete contacts.
I can create the button fine, I'm just a bit puzzled as to how to decide where to put it.
I thought I could just do:
CGRect bounds = [[self tableView] bounds];
Then place the button based on that.
However, when accessing the size.height of bounds I get zero! Is there a dynamic way to retrieve the tableView's height that I could be missing?
Any help is greatly appreciated.

回答1:
You can create the size of your button like
CGRect buttonFrame = CGRectMake(0, 0, width, height);
Create the button with that frame, and then set the button as the tableView's footer
myTableView.tableFooterView = myButton;

You could try making a custom footer view with those buttons placed in that view by implementing these methods:
- (CGFloat) tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
- (UIView *) tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
That should let you put any number of buttons on your table underneath the section you want.

You can get the tablewViews heigh by looking at its frame
CGRect bounds= [[self tableView] frame];
float heigh= frame.size.height;
