ios：如何从IB中的一个视图创建两个不同的视图？

Question

I created a custom UIView in Intefacebuilder. In my ViewController I want to create two instances of my UIViews.

So here is some code:

@interface MeineFinanzenViewController : UIViewController <UIGestureRecognizerDelegate> {

UISwipeGestureRecognizer* swipeLeft;
UISwipeGestureRecognizer* swipeRight;

//... other stuff

SaldoView* ausgabenView;
SaldoView* einnahmenView;

}

//...other stuff
@property (strong,nonatomic) IBOutlet SaldoView* ausgabenView;
@property (strong,nonatomic) IBOutlet SaldoView* einnahmenView;
//...other stuff

So I connected the same view two times. Firstly to ausgabenView and secondly to einnahmenView. BUT after that the ausgabenView becomes the same object as einnahmenView. Actually I would like to have two separated objects that are independent from each other. Now I'm asking myself how to achieve this?

Any hints?

Answer 1

You should load your view manually:

- (SaldoView *)loadCustomView {

    NSArray* nibViews = [[NSBundle mainBundle] loadNibNamed:@"NibFileName" owner:nil options:nil];
    for (id object in nibViews) {
        if ([object isKindOfClass:[SaldoView class]]) {
            return (SaldoView *)object;
        }
    } 
    return nil;
}

And create two instance of views

    SaldoView* ausgabenView = [self loadCustomView];
    SaldoView* einnahmenView = [self loadCustomView];  

Answer 2

If you are creating your views by editing your nib files graphically - as it seems you are - then if you want two views, then you drag two views onto the editor from the library. You then connect one to each outlet.
