今天在做练习创建多个视图程序的时候，老是出现下面这样的错误：
?
p.p1 {margin: 0.0px 0.0px 0.0px 28.0px; text-indent: -28.0px; font: 11.0px Menlo}?
'-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "BlueView" nib but the view outlet was not set.'
?
查书才知道，没有做nib文件到xxxViewControler程序的关联，特此记录下来:
?
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
?
- (IBAction)gagal:(id)sender {? ? NSLog(@"sggsg"); ? BnViewController * next = [[BnViewController alloc]initWithNibName:@"MyView" bundle:nil]; ? ? [self presentViewController:next animated:YES completion:nil];? ? //[self.navigationController pushViewController:next animated:YES];} 48448495
