ios - executing blocks stored in NSMutableArray with a parameter -

i'm trying understand blocks bit more.

i have these definitions:

@property (nonatomic, retain) nsmutablearray * callbacksonsuccess; @property (nonatomic, copy) void (^callbacksuccesswithuiimage) (uiimage *) ;

when image download finishes in completion block , things fine

uiimage *coverimage = [uiimage imagewithdata:data]; callbacksuccesswithuiimage(coverimage);

now i'd able same callback blocks stored in callbacksonsuccess nsmutablearray don't know how approach this.

i'm trying in loop, that's not working because of ambigous id class definition:

uiimage *coverimage = [uiimage imagewithdata:data]; (id callbackblock in callbacksonsuccess)  {callbackblock(coverimage);}

please push me towards right approach.

thank you!

first of all:

consider use typedef blocks, in order ease syntax:

typedef void (^myblock)(uiimage*); //declare somewhere

then, can iterate through array this, executing each block inside it:

uiimage *coverimage = [uiimage imagewithdata:data]; (myblock block in callbacksonsuccess) {     block(coverimage); }

you can use new type in property:

@property (nonatomic, copy) myblock callbacksuccesswithuiimage;
