如何从NSString中解析数字？

Answer 1

用下面的代码实现

NSString *numberVector = @"(\n 1,\n 2,\n 3,\n 4\n)";    
NSString *onlyNumbers = [numberVector  stringByReplacingOccurrencesOfString:@"[^0-9,]" withString:@"" options:NSRegularExpressionSearch range:NSMakeRange(0, [numberVector  length])];
NSArray *numbers=[onlyNumbers componentsSeparatedByString:@","];
NSLog(@"%@",numbers);
