Finding the Current First Responder 

In iOS there is no simple call to retrieve the current first responder (without resorting to private APIs)

#import "UIResponder+FirstResponder.h"

static __weak id currentFirstResponder;

@implementation UIResponder (FirstResponder)

+(id)currentFirstResponder {

currentFirstResponder = nil;
[[UIApplication sharedApplication] sendAction:@selector(findFirstResponder:) to:nil from:nil forEvent:nil];
return currentFirstResponder;

}

-(void)findFirstResponder:(id)sender {

currentFirstResponder = self;

}

@end
