就像輸入字符串(個體經營)上面的代碼是:NSRegularExpression在Objective-C
[04:30.50]There are pepole dying
[04:32.50]If you care enough for the living
[04:35.50]Make a better place for you and for me
[04:51.50][04:45.50][04:43.50][04:39.50]You and for me
,我想獲得團體爲[04:51.50][04:45.50][04:43.50][04:39.50]
,但我只能得到最後的[04:39.50]
是在NSRegularExpression
只能得到最後一組,當我搜索(($1)($2)($3)){2}
