NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"(\\[(\\d{2}):(\\d{2})\\.(\\d{2})\\])+(.+)" options:NSRegularExpressionAllowCommentsAndWhitespace error:&error];

[*lyricObject addObject:[self substringWithRange:[match rangeAtIndex:5]]];
NSLog(@"%@",[self substringWithRange:[match rangeAtIndex:1]]);
[*stamp addObject:[NSString stringWithFormat:@"%d", ([[self substringWithRange:[match rangeAtIndex:2]] intValue] * 60 + [[self substringWithRange:[match rangeAtIndex:3]] intValue] ) * 100 + [[self substringWithRange:[match rangeAtIndex:4]] intValue]]];

就像输入字符串(self)上面的代码一样:
[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
我想得到for groups,[04:51.50][04:45.50][04:43.50][04:39.50]
但我只能得到最后一个[04:39.50]
NSRegularExpression
我搜索时只能得到最后一组吗(($1)($2)($3)){2}
