case NSOrderedSame: NSLog(@"两个字符串一样"); break; } 输出结果: 后面一个字符串大于前面一个 -(NSComparisonResult) caseInsensitiveCompare:(NSString *)string; 忽略大小写进行比较,返回值与compare:一致 NSString *str1 = @"abc"; NSString *str2 = @"ABC"; ...
原型：extern int strcmp(char *s1,char * s2);用法：#include <string.h> 功能：比较字符串s1和s2。说明：当s1<s2时，返回值<0 当s1=s2时，返回值=0 当s1>s2时，返回值>0 举例：// strcmp.c include <syslib.h> include <string.h> main(){ char *s1="Hello, Programmers!";char ...
