有人可以指导我完成所有步骤,因为我感到有些卡住和迷路
上一个问题:iOS - set UIButton target and action from its super class
现在,我试图获得一个更笼统的想法-我对此很陌生
非常感谢帮助
最佳答案
如果要从视图控制器本身内部访问关联的UIViewController的UIView,则只需使用self.view
。要从UIViewController类的外部访问同一UIView,可以使用该类的实例名称以及.view
属性。例如:
//SomeClass.m
- (void)accessVCView
{
//With a Nib File:
MyUIViewController *aVCObject = [[MyUIViewController alloc] initWithNibName:@"MyNib" bundle:nil];
//Or with a Storyboard:
MyUIViewController *aVCObject = [[UIStoryboard storyboardWithName:@"myStoryboard" bundle:nil] instantiateViewControllerWithIdentifier:@"MyViewController"];
UIView *myUIViewControllerView = aVCObject.view;
}
