Setup and send custom delegate method within init? - objective-c

Question

i have a question about initializing a custom delegate.
Within MyScrollView initWithFrame method, there is the first position where i need to send my delegate. But it´s still unknown there, because i set the delegate within MyCustomView after the initializer.
How can i fix that, so the delegate gets called even within init?
Thanks for your help..
MyCustomView.m
self.photoView = [[MyScrollView alloc] initWithFrame:frame withDictionary:mediaContentDict];
self.photoView.delegate = self;
//....
MyScrollView.h
#protocol MyScrollViewDelegate
-(void) methodName:(NSString*)text;
#end
#interface MyScrollView : UIView{
//...
__unsafe_unretained id <MyScrollViewDelegate> delegate;
}
#property(unsafe_unretained) id <MyScrollViewDelegate> delegate;
MyScrollView.m
-(id) initWithFrame:(CGRect)frame withDictionary:(NSDictionary*)dictionary{
self.content = [[Content alloc] initWithDictionary:dictionary];
self = [super initWithFrame:frame];
if (self) {
//.... other stuff
// currently don´t get called
[self.delegate methodName:#"Test delegate"];
}
return self;
}

Answer 1

I am sure you have defined a:
- (id)initWithFrame:(CGRect)frame withDictionary:(NSDictionary *)dictionary;
Then, just pass the delegate, too:
- (id)initWithFrame:(CGRect)frame withDictionary:(NSDictionary *)dictionary withDelegate:(id<MyScrollViewDelegate>)del;
In the Implementation File:
- (id)initWithFrame:(CGRect)frame withDictionary:(NSDictionary *)dictionary withDelegate:(id<MyScrollViewDelegate>)del {
// your stuff...
self.delegate = del;
[self.delegate methodName:#"Test delegate"];
}
Use it:
self.photoView = [[MyScrollView alloc] initWithFrame:frame withDictionary:mediaContentDict withDelegate:self];

One option might be to pass in your delegate in your custom class's initializer:
-(id)initWithFrame:(CGRect)frame withDictionary:(NSDictionary*)dictionary delegate:(id)delegate
{
self = [super initWithFrame:frame];
if (self == nil )
{
return nil;
}
self.content = [[Content alloc] initWithDictionary:dictionary];
self.delegate = delegate;
//.... other stuff
// Delegate would exist now
[self.delegate methodName:#"Test delegate"];
return self;
}
