ios判断字符串是否包含某个字母

NSString *women = @"123456789?";

if ([women containsString:@"1"]) {
    
    NSLog(@"women 包含 1");
    
} else {
    
    NSLog(@"women 不存在 1");
    
}


NSString *string = @"hello,fucking,you,bitch";

//字条串是否包含有某字符串

if ([string rangeOfString:@"fucking"].location == NSNotFound) {
    
    NSLog(@"string 不存在 fucking");
    
} else {
    
    NSLog(@"string 包含 fucking");
    
}
