View factory for iOS - ios

Question

I am trying to create a View factory for iOS and I am getting into some trouble. The view factory should be a able to create multiple UIImageViews, MKMapViews or UIWebViews and add them to a view vertically. I have a problem with the web view cause I have to wait for webViewDidFinishLoad. If the methods are implemented in the ViewController which implements the UIWebViewDelegate and the delegate of the webviews is set to the controller everything works fine. The thing is that I want to put all of this in a separate class but the webViewDidFinishLoad is never been called. Is there a way to achieve that?
Tell me if you need any code
Code:
Part is added
- (void)addPart
{
if (self.viewPartStrings.count != 0) {
NSString *viewPartString = [self.viewPartStrings objectAtIndex:0];
NSString *viewPartIdentifier = [self getViewPartIdentifier:viewPartString];
NSString *viewPartDefinition = [self getViewPartDefinition:viewPartString];
if ([viewPartIdentifier isEqualToString:kWeb]) {
[self createTextWebViewPart:viewPartIdentifier];
} else if ([viewPartIdentifier isEqualToString:kMap]) {
[self createMapViewPart:viewPartDefinition];
} else if ([viewPartIdentifier isEqualToString:kImage]) {
[self createImageViewPart:viewPartDefinition];
}
}
}
Views are created:
- (void)createTextWebViewPart:(NSString *)viewPartText
{
WebViewPart *webViewPart = [[WebViewPart alloc]initWithFrame:[self getViewPartFrameForHeight:0]];
[webViewPart createViewForText:viewPartText];
[webViewPart setDelegate:self];
}
- (void)createImageViewPart:(NSString *)viewPartDefinition
{
//create image
}
- (void)createMapViewPart:(NSString *)viewPartDefinition
{
//create map
}
But here is the point. This method is never called. Not if the class extends NSObject and not if the class extends UIView:
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
CGRect frame = webView.frame;
frame.size.height = 1;
webView.frame = frame;
CGSize fittingSize = [webView sizeThatFits:CGSizeZero];
frame.size = fittingSize;
[webView stringByEvaluatingJavaScriptFromString:#"document.body.style.webkitTouchCallout='none';"];
int height = frame.size.height + 70;
[self addToView:webView forHeight:height];
}
EDIT: I also tried doing this in the Controller:
#interface DetailController ()
#property (nonatomic, strong) ViewPartsFactory *viewPartsFactory;
#end
Then:
- (void)setViewForModel:(DealModel *)model
{
//...
self.viewPartsFactory = [[ViewPartsFactory alloc]initWithViewParts: [descriptionParser getViewParts]];
UIView *view = [self.viewPartsFactory getView]
[scrollView addSubview:view];
//..
}
and
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
[self.viewPartsFactory webViewDidFinishLoad:webView];
}
setting the webview delegates to the controller but still nothing.

I'll answer this in super-pseudo code and hopefully it'll give you an idea of what I'm suggesting.
// ViewPartsFactory.h
-(void)webViewDidFinishLoad; // implement your logic in this method
// Ensure you DO NOT set the delegate anywhere here, otherwise it'll override when you set it in the view controller.
//--------------------------------------------------//
// DetailController.m
#property (nonatomic, weak) id <UIWebViewDelegate> delegate;
DetailController <UIWebViewDelegate>
-(void)viewDidLoad {
self.delegate = viewPartsFactory;
}
