A framework to delay handling responder chain actions further up the chain. Read the rationale behind this on this blog post.
You have a few different options:
- Include the LateResponders.xcodeproj as a dependency in your project.
- Copy the source files manually to your project.
Add LateResponders as a dependency on your Cartfile:
github "OuterCorner/LateResponders"
And run:
carthage update
Implement the OCLateResponderRegistering protocol on a responder high up the responder chain. On iOS this could be the root view controller for example.
@interface RootViewController <OCLateResponderRegistering>
@end
@implementation RootViewController {
OCLateResponderRegistry *_registry;
}
#pragma mark - Late responders
- (OCLateResponderRegistry *)lateResponderRegistry
{
if (_registry == nil) {
_registry = [[OCLateResponderRegistry alloc] init];
__weak typeof(self) wSelf = self;
_registry.lastResponder.nextResponderBlock = ^UIResponder *{
return [wSelf superNextResponder];
};
}
return _registry;
}
- (UIResponder *)nextResponder
{
return [self.lateResponderRegistry initialResponder];
}
- (UIResponder *)superNextResponder
{
return [super nextResponder];
}To register late responders with the registry you could do something like this:
- (void)registerLateResponders
{
OCLateResponderRegistry *registry = [[self lateResponderRegisteringViewController] lateResponderRegistry];
[self.lateResponder deregister];
OCLateResponderProxy *proxy = [[OCLateResponderProxy alloc] initWithProxiedResponder:self weight:20];
proxy.proxiedSelectorNames = @[
NSStringFromSelector(@selector(action1:)),
NSStringFromSelector(@selector(action2:)),
];
proxy.keyCommands =
@[
[UIKeyCommand keyCommandWithInput:@"1" modifierFlags:UIKeyModifierCommand action:@selector(action1:)],
[UIKeyCommand keyCommandWithInput:@"2" modifierFlags:UIKeyModifierCommand action:@selector(action2:)]
];
[registry registerLateResponder:proxy];
self.lateResponder = proxy;
