objective c - How to pass a SEL to dispatch_async method -

i trying create generic method takes sel parameter , passes dispatch_async execution, clueless how execute passed in sel. can here me please.

// test.m  -(void) executeme {     nslog(@"hello"); }  - (void)viewdidload {     [super viewdidload];     sel executesel = @selector(executeme);     [_pinst common_dispatch: executesel]; }  // common.m -(void) common_dispatch:(sel) aselector {     dispatch_async(idispatchworkerqueue, ^(void) {         // how execute aselector here?     }); } 

you need have "target" parameter on common_dispatch method since need call selector on specific object.

- (void)viewdidload {     [super viewdidload];      sel executesel = @selector(executeme);     [_pinst common_dispatch:executesel target:self]; }  - (void)common_dispatch:(sel)aselector target:(id)target {     dispatch_async(idispatchworkerqueue, ^(void) {         [target performselector:aselector];     }); } 

btw - standard naming conventions state method names should begin lowercase , use camelcase. method should commondispatch.
