用xib自定义UIView并在代码中使用--iOS

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
//获得nib视图数组

NSArray *nibContents = [[NSBundle mainBundle] loadNibNamed:@"HeadView" owner:nil options:nil];
// Find the view among nib contents (not too hard assuming there is only one view in it).
// 得到最后一个view

HeadView *headView = [nibContents lastObject];
headView.frame = CGRectMake(0, 0, 300, 200);
//headView.backgroundColor = [UIColor blueColor];
_tableView.tableHeaderView = headView;
}
