查找字符串中字符的索引

Question

我有一个字符串NSString *Original=@"88) 12-sep-2012";或Original=@"8) blablabla";

我想只打印")"之前的字符,以便如何找到字符")"的索引.或者我怎么能这样做？

提前致谢.

Answer 1

NSString *str = [[yourString componentsSeparatedByString:@")"] objectAtIndex:0];
NSLog(@"%@", str);

// If you need the character index:
NSUInteger index = str.length;

Answer 2

你可以找到字符")"的索引,如下所示:

NSString *Original=@"88) 12-sep-2012";
NSRange range = [Original rangeOfString:@")"];
if(range.location != NSNotFound)
{
 NSString *result = [Original substringWithRange:NSMakeRange(0, range.location)];
}

Answer 3

您可以使用以下代码查看“）”之前的字符

   // this would split the string into values which would be stored in an array
   NSArray *splitStringArray = [yourString componentsSeparatedByString:@")"];
   // this would display the characters before the character ")"
   NSLog(@"%@", [splitStringArray objectAtIndex:0]);
