引入xib

通过xib创建的cell

一、注册创建法：

[self.treeView registerNib:[UINib nibWithNibName:NSStringFromClass([MerchantSearchSelectCell class]) bundle:nil] forCellReuseIdentifier:self.selectTVC];

二、数据源方法内创建法：

cell = [[NSBundle mainBundle] loadNibNamed:NSStringFromClass([MerchantIntroTableViewCell class]) owner:nil options:nil][0];

if(cell == nil){

cell = [[[NSBundle mainBundle] loadNibNamed:@"Level0_Cell" owner:self options:nil] lastObject];

}

通过xib创建的控制器

PersonalInfoNewViewController *personalInfo = [[PersonalInfoNewViewController alloc] initWithNibName:@"PersonalInfoNewViewController" bundle:nil withHeadImage:self.headImageView.image];
