UITapGestureRecognizer + blocks + UIView category = Add tap gestures with ease

gistfile1.m

// In UIVIew category...
#import <objc/runtime.h>
- (void)addTapGestureWithBlock:(void(^)())wasTappedBlock
{
    static int selectorId = 0;
    NSString *selectorName = [NSString stringWithFormat:@"tapGestureSelector%d:",selectorId];
    IMP implementation = imp_implementationWithBlock(wasTappedBlock);
    SEL newSelector = @selector(selectorName);
    class_addMethod([self class], newSelector, implementation, "v@:@");
    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:newSelector];
    [self addGestureRecognizer:tapGesture];
}

// Example Usage
[self.tableView addTapGestureWithBlock:^{
        [self.view endEditing:YES];
    }];

It seems the selector is not unique and this therefor fails when applying to multiple objects (at least for me it did). It looks like a solution was started with selectorId but then not completed? (I may be wrong)

This is my version: can use this code whithout function only need import

#import <objc/runtime.h>

NSString *uuid = [[NSUUID UUID] UUIDString];

IMP implementation = imp_implementationWithBlock(^{

   //Your code here

});

SEL newSelector = @selector(uuid);

class_addMethod([self class], newSelector, implementation, "v@:@");

[!! Your UIButton Here !!:self action:newSelector forControlEvents:UIControlEventTouchUpInside];

I thought about using this technique until I realized that all those class methods never get cleaned up. It's kind of a terrible idea...
