(1) 打开nib文件
(2)点击"File's Owner", 按command+4,设置Class为xxxViewControler
(3) 按Control+"Files's Owner", 里面有个默认的IBOutlet变量view, 看一下后面有没有做关联,如果没有就拉到下面的View和视图做个关联
FirstViewController* firstViewController =[[FirstViewControlleralloc]initWithNibName:@"firstTT"bundle:nil];
UIStoryboard *futureStoryBoard = [UIStoryboardstoryboardWithName:@"Main"bundle:nil];
FirstViewController* firstViewController = [futureStoryBoard instantiateViewControllerWithIdentifier:@"first"];
