Objective-C – How to Shuffle a NSMutableArray
You can use the following piece of code to randomize/shuffle the objects inside a NSMutableArray.
/* anArray is a NSMutableArray with some objects */
srandom(time(NULL));
NSUInteger count = [anArray count];
for (NSUInteger i = 0; i < count; ++i) {
int nElements = count - i;
int n = (random() % nElements) + i;
[anArray exchangeObjectAtIndex:i withObjectAtIndex:n];
}
Update @ 2012-07-18: Suggestion from kimbebot
/* anArray is a NSMutableArray with some objects */
NSUInteger count = [anArray count];
for (NSUInteger i = 0; i < count; ++i) {
int nElements = count - i;
int n = (arc4random() % nElements) + i;
[anArray exchangeObjectAtIndex:i withObjectAtIndex:n];
}
Done =)

維園良心 – 謝志峰
二零一零年五月十六日，主持了《城市論壇》近十年的謝志峰，竟然出現第一 次心寒的感覺。
這天論壇，「曲線」討論類近補選的議題，「維園阿哥」號召數百「紅衫仔」逼爆會場，結果創出《城市論壇》市民出席人數紀錄，約450。「……當日我真係驚出事，係第一次驚！觀眾進場時，《Wall Street Journal》的記者正在訪問我，我看見那班年輕人進場時的狀態－－嘩！那種急切、盼望、希冀，恐怕佔不到座位的惶恐心情。憑一個記者的直覺，我立時叫正在訪問我的《Wall Street Journal》記者先拍下這個千載難逢的Moving Shot，然後我問她：『你看到他們的神情嗎？』」
謝志峰說，當時他看到的，是數百對饑渴的眼神，他們在掠奪一個發言的機會、一個表達不滿的宣洩途徑、一種希望政府聽到他們聲音的欲望！「我做了那麼多年論壇主持，在『五一六』那天才是第一次看到這種眼神，才第一次感到可能出亂子。」幸而剛好三十周年《城市論壇》這天大步檻過，紅衫仔沒有變成紅衫軍，只有慷慨激昂沒有流血衝突，謝志峰謝天謝地！
