问题描述

M作为messenger App工作。
i希望在我的客户端上自动发送短信作为验证码，用户可以使用该代码作为验证码..
任何人都可以帮助我如何在我的客户端自动发送短信

M working on as messenger App .i want to sent automatically sms on my client as a verification code and user can use that code as a verification code ..Can any one help me how to sent sms automatically on my client

如果用户在那时点击注册，他/她将自动从iphone客户端获取确认短信。
那是我需要实现的..

If user click on register at that time he/she will get conformation sms automatically from iphone client .That what i need to implement ..

推荐答案

这是有关编码/解码的问题的扩展名：

This is the extension for your question regarding Encoding/Decoding:

#import <Foundation/Foundation.h>


@interface Base64 : NSObject {

}

+ (void) initialize;

+ (NSString*) encode:(const uint8_t*) input length:(NSInteger) length;

+ (NSString*) encode:(NSData*) rawBytes;

+ (NSData*) decode:(const char*) string length:(NSInteger) inputLength;

+ (NSData*) decode:(NSString*) string;

@end




#import "Base64.h"


@implementation Base64

#define ArrayLength(x) (sizeof(x)/sizeof(*(x)))


static char encodingTable[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
static char decodingTable[128];

+ (void) initialize {
    if (self == [Base64 class]) {
        memset(decodingTable, 0, ArrayLength(decodingTable));
        for (NSInteger i = 0; i < ArrayLength(encodingTable); i++) {
            decodingTable[encodingTable[i]] = i;
        }
    }
}


+ (NSString*) encode:(const uint8_t*) input length:(NSInteger) length {
    NSMutableData* data = [NSMutableData dataWithLength:((length + 2) / 3) * 4];
    uint8_t* output = (uint8_t*)data.mutableBytes;

    for (NSInteger i = 0; i < length; i += 3) {
        NSInteger value = 0;
        for (NSInteger j = i; j < (i + 3); j++) {
            value <<= 8;

            if (j < length) {
                value |= (0xFF & input[j]);
            }
        }

        NSInteger index = (i / 3) * 4;
        output[index + 0] =                    encodingTable[(value >> 18) & 0x3F];
        output[index + 1] =                    encodingTable[(value >> 12) & 0x3F];
        output[index + 2] = (i + 1) < length ? encodingTable[(value >> 6)  & 0x3F] : '=';
        output[index + 3] = (i + 2) < length ? encodingTable[(value >> 0)  & 0x3F] : '=';
    }

    return [[[NSString alloc] initWithData:data
                                  encoding:NSASCIIStringEncoding] autorelease];
}


+ (NSString*) encode:(NSData*) rawBytes {
    return [self encode:(const uint8_t*) rawBytes.bytes length:rawBytes.length];
}


+ (NSData*) decode:(const char*) string length:(NSInteger) inputLength {
    if ((string == NULL) || (inputLength % 4 != 0)) {
        return nil;
    }

    while (inputLength > 0 && string[inputLength - 1] == '=') {
        inputLength--;
    }

    NSInteger outputLength = inputLength * 3 / 4;
    NSMutableData* data = [NSMutableData dataWithLength:outputLength];
    uint8_t* output = data.mutableBytes;

    NSInteger inputPoint = 0;
    NSInteger outputPoint = 0;
    while (inputPoint < inputLength) {
        char i0 = string[inputPoint++];
        char i1 = string[inputPoint++];
        char i2 = inputPoint < inputLength ? string[inputPoint++] : 'A'; /* 'A' will decode to \0 */
        char i3 = inputPoint < inputLength ? string[inputPoint++] : 'A';

        output[outputPoint++] = (decodingTable[i0] << 2) | (decodingTable[i1] >> 4);
        if (outputPoint < outputLength) {
            output[outputPoint++] = ((decodingTable[i1] & 0xf) << 4) | (decodingTable[i2] >> 2);
        }
        if (outputPoint < outputLength) {
            output[outputPoint++] = ((decodingTable[i2] & 0x3) << 6) | decodingTable[i3];
        }
    }

    return data;
}


+ (NSData*) decode:(NSString*) string {
    return [self decode:[string cStringUsingEncoding:NSASCIIStringEncoding] length:string.length];
}

@end
