多条件字符串分割

需求：以。或者!或者？分割字符串

思路一：

NSString *testStr = @"我的世界观。我的美女？我的老板！哈哈哈。";

NSString *pageStr = [self stringOfPage:index];  

  NSMutableArray*synthesisTexts = [NSMutableArrayarray]; 

  NSArray*synthesisTemp = [testStr componentsSeparatedByString:@"。"];

在遍历NSArray数组分别以？！分割

思路二：采用正则表达式分割

NSString *testStr = @"我的世界观。我的美女？我的老板！哈哈哈。";

__block NSRange lastRange = NSMakeRange(-1, 0);

NSError *error = NULL;

NSRegularExpression *fieldRegularExpression = [NSRegularExpression

regularExpressionWithPattern:@"[。？！]"

options:NSRegularExpressionCaseInsensitive

error:&error];

[fieldRegularExpression enumerateMatchesInString:testStr options:0 range:NSMakeRange(0, [testStr length])

usingBlock:^(NSTextCheckingResult *match, NSMatchingFlags flags, BOOL *stop){

NSString *splitStr = [testStr substringWithRange:NSMakeRange(lastRange.location + 1, match.range.location - lastRange.location)];

NSLog(@"%@---%ld",splitStr,match.range.location+1);

lastRange = match.range;

}];

}
