iphone - UIImageView animation - using perform selector after delay to display last image in the array -

-

basically, have uiimageview loop through 8 pngs on 0.5 seconds. @ same time start animation, performselector afterdelay of 0.5 seconds. after uiimageview has finished animating call animationtickdone set last image hidden no.

here's code anyway:

.h @interface viewcontroller : uiviewcontroller{     iboutlet uiview *scannedview;     iboutlet uiimageview *animatedticklast; } @property (nonatomic, retain) iboutlet uiview *scannedview; @property (nonatomic, retain) iboutlet uiimageview *animatedticklast;  .m -(void)found{         [self.view addsubview:scannedview];         [animatedticklast sethidden:yes];         //place animated tick images array         nsmutablearray *animatedtickimages;         animatedtickimages = [[nsmutablearray alloc] init];         nsuinteger nimages = 0;         (nimages=0; nimages<8; nimages++){             nsstring *tickimagename = [nsstring stringwithformat:@"tick_%d.png", (nimages + 1)];             [animatedtickimages addobject:[uiimage imagenamed:tickimagename]];         }         //set animated tick         uiimageview *animatedtick = [[uiimageview alloc] initwithframe:cgrectmake(98, 213, 125, 90)];         [animatedtick setanimationimages:animatedtickimages];         [animatedtick setanimationduration:0.5];         [animatedtick setanimationrepeatcount:1];         [animatedtick startanimating];         nslog(@"animation started");         [self performselector:@selector(animationtickdone) withobject:nil afterdelay:0.5];         [scannedview addsubview:animatedtick];         nslog(@"animation added view");         [animatedtickimages release]; } - (void)animationtickdone{     nslog(@"delay function begins");     [animatedticklast sethidden:no];     sleep(1); //sleep scannedview stays on screen @ least 1.5 seconds (0.5 after animation + 1 sleep); }

now, problem. animation fine, , works great. when found() first called, animatedticklast become visible after animation. when ever found called again afterwords, animatedtickdone never appears again, it's empty space.

after hours looking around web searching , playing it, cannot understand issue why doesn't appear. thought @ 1 point sleep() getting called before animatedticklast chance set hidden no, after removing sleep() still didn't work.

driving me nuts appreciated.

thanks!

if understand correctly want image after animaton in uiimageview. set image before animation , fine!

[animatedtick setanimationimages:animatedtickimages]; [animatedtick setanimationduration:0.5]; [animatedtick setanimationrepeatcount:1]; [animatedtick setimage:theimageyouliketohave]; [animatedtick startanimating];

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
