Click the button to switch xib files iphone

Just learning iphone development, now encounter a problem using this code
- (IBAction) RetrunClick: (id) sender
{
[[NSBundle mainBundle] loadNibNamed: @ "HotIndex" owner: self options: nil];
}

In normal operation the system can generate a program, I added the interface on the error Thread1: Program received signal: "SIGABRT"

Boss help

You want to click on different buttons to add different xib it?
Or just click a button to add xib?
CustomView * myview = [[[NSBundle mainBundle] loadNibNamed: @ "CustomView" owner: self options: nil] lastObject];
Try.
Well see there is no association, or other attributes have not forgotten what set up.
