从xib/nib加载UIViewController/或其子类
【之所以】
xib、nib文件目的在于为控件快速定位
这里仅针对UIViewController和其子类
【How】
这里整理并描述两种方式的使用:
1、UIViewController initWithNibName
主要代码如下:
StarterController *starter = [[StarterController alloc] initWithNibName:@"StarterController" bundle:nil];
NSLog(@"starter = %@" ,starter);
if (starter)
{
NSLog(@"%@ parent controller is %@" ,starter ,starter.parentViewController);
NSLog(@"%@ nav controller is %@" ,starter ,starter.navigationController);
}
注意参数bundle,暂时不知道怎么获取,后续解答。
StarterController.xib,如图,此处File Owner ,Class = StarterController,此类继承UIViewController

2、NSBundle loadNibNamed
主要代码如下:
NSArray *niblets = [[NSBundle mainBundle] loadNibNamed:@"sample" owner:self options:NULL];
for (id theObject in niblets)
{
if ([theObject isKindOfClass:[UIViewController class]])
[self.navigationController pushViewController:theObject animated:YES];
}
sample.xib,如图,特别注意File Owner,这个类是NSObject

【其他】
在实践中,出现一个问题:“loaded the...nib but the view outlet was not set”
