我目前正在开展一个具有很多相似性的项目。
我知道是否有办法将子视图从根类发送到继承的类。
这是我的RootViewController:
@class CustomView;
@interface RootViewController : UIViewController {
IBOutlet CustomView *_aCustomView;
}
@end
@implementation RootViewController
- (void)viewDidLoad {
[super viewDidLoad];
UISwipeGestureRecognizer *swipRecognizer;
// swipe left management
swipRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self
action:@selector(handleSwipeFrom:)];
swipRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
swipRecognizer.numberOfTouchesRequired = 2;
swipRecognizer.delegate = self;
[self.view addGestureRecognizer:swipRecognizer];
[swipRecognizer release];
}
- (void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer
{
NSLog(@"swip detected");
[self.view addSubview:_aCustomView];
}
HomeViewController:
@interface HomeViewController : RootViewController {
}
@end
我会创建一些ViewController,它继承自RootViewController
HomeViewController
,以保存行代码。当我在HomeViewController
时,我检测到我的滑动但我还没有设法将我的自定义subView
(来自我的RootViewController)添加到我的HomeViewController。
很多。

您应该在自定义视图中添加构造函数方法,该方法使用模型中的对象初始化视图。
例如:
我的RootViewController是一个Customer对象,一个CustomerView显示有关该客户的信息。
在CustomerView中,您应该创建一个方法:
-(id) initWithFrame:(CGRect) frame customer:(Customer) customer;
如果您需要在HomeViewController中显示相同的CustomerView,只需添加一个Customer对象作为HomeViewController的属性,并在viewDidLoad中添加一个CustomerView:
CustomerView *customerView = [[CustomerView alloc] iniFrame:CGRectMake(...) customer:currentCustomer;
[self.view addSubView:customerView];
[customerView release];
希望这有帮助, 文森特。

我找到了解决方案。我的问题是关于我试图添加一个未初始化的IBOutlet对象希望我以后不会后悔:
在我的HomeViewController中,我覆盖了方法initWithNibName:bundle:
:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization.
}
return self;
}
我的RootViewController:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:@"RootViewController" bundle:nibBundleOrNil];
if (self) {
// Custom initialization.
}
return self;
}
