Passing parameters in self action:@selector

Question

I am trying to add a NSIndexpath as parameter to a method through

[self action:@selector(showDetailedImage)];

Is it possible to add an extra parameter(NSIndexPath) to this method?

Answer 1

No, you can not pass arguments, you can only show that this selector will take that many numbers of arguments.

If you need to do this, you can create a property and access it from the method showDetailedImage.

However you can use this selector:

[self performSelector:@selector(showDetailedImageIndex:) withObject:objectOfNSIndex];

Answer 2

Make a wrapper(another method) say -(void)wrapperMethodOforiginalSelectorMethod; of your now-selector-method say -(void)originalSelectorMethod:(id)argument; and make the wrapper as your new selector which further calls your originalSelectorMethod with your argument.

Answer 3

You have to add extra parameter to

ShowDetailedImage:(NSIndexPath *)indexPath

can call [self action:@selector(showDetailedImage:)];
