问题描述
你好我有这样的字符串:
HelloI have a string like this:
Results for: 123D12
2010
2009
2008
2007
2006
YEAR: 2006 WEEK: 2 PRODIDNUM: 37911
ACCESSKEY: FA3540B52F
2005
2004
YEAR: 2004 WEEK: 22 PRODIDNUM: 46178
ACCESSKEY: 58B2509373
我想找出ACCESSKEY来帮助我获取十六进制数(在这种情况下为FA3540B52F和58B2509373).
and I want to spot the ACCESSKEY to help me get the hexadecimal(in this case are FA3540B52F and 58B2509373).
问题在于,当我使用rangeOfString获取访问密钥时,它只会停止到第一个!这是我的代码:
The issue is that when I use rangeOfString to get the accesskey it stops only to the first one! This is my code:
if ([strippedString rangeOfString:@"ACCESSKEY"].location != NSNotFound ) {
NSUInteger int1=[strippedString rangeOfString:@"ACCESSKEY"].location;
NSString *finssid = [strippedString substringWithRange:NSMakeRange(int1+11,10)];
NSLog(@"Output = Found it %d \n",int1);
NSLog(@"Output =%@ \n \n",finssid);
}
我在这里做错了什么?
推荐答案
尝试一下:
NSRange searchRange = NSMakeRange(0, [strippedString length]);
BOOL keepGoing = YES;
// Find all ssid
while (keepGoing) {
NSRange accessWord = [strippedString rangeOfString:@"ACCESSKEY" options:NSCaseInsensitiveSearch range:searchRange];
if (accessWord.location != NSNotFound) {
// since we have found the access key, we can assume somethings
// ACCESSKEY: FA3540B52F
int pos = accessWord.location + 11;
NSString *ssid = [strippedString substringWithRange:NSMakeRange(pos, pos + 10)];
NSLog(@"SSID: %@", ssid);
// reset our search up a little for our next loop around
searchRange = NSMakeRange(pos, [strippedString length] - pos);
} else {
keepGoing = NO;
}
}
