int16_t 强转为uint16_t int32_t 强转为uint32_t#无符号转有符号如: uint8_t 强转为int8_t uint16_t 强转为int16_t uint32_t 强转为int32_t 举例: int32_t val = -121; uint32_t new = (uint32_t)val; printf("val = 0x%x, %d, new = 0x%x, %d\n", val, val, new, new);...
NSData*data = [aString dataUsingEncoding:NSUTF8StringEncoding];//通过utf-8转为data9.NSData转Uint8+ (uint8_t)uint8FromBytes:(NSData *)fData { NSAssert(fData.length==1,@"uint8FromBytes: (data length != 1)"); NSData*data =fData; uint8_t val=0; [data getBytes:&val length:1];...
int a = [aStrinng intValue]; 5.uint8转NSData(占两位) + (NSData *)byteFromUInt8:(uint8_t)val { NSMutableData *valData = [[NSMutableData alloc] init]; unsigned char valChar[1]; valChar[0] = 0xff & val; [valData appendBytes:valChar length:1]; return [self dataWithReverse:valDa...

(7条消息)C字符串与uint32类型互相转换 1.字符串转换为 unsigned int 类型 /*将传入的字符串转换为无符号的的32位整形 *@param: str : 传入的字符串 *retval: The converted value. */ static unsigned int atoui(const char *str); unsigned int atoui(const char *str)...
静静分析了下,c#工程师是把每个数据转成uint,然后去校验的。于是,费尽九牛二虎之力,将每个数据都转成uint32的整数,实现代码如下(在网上找的) public static long bytes2int(byte[] src){ int firstByte = 0; int secondByte = 0; int thirdByte = 0; ...
16.NSData转int16_t //bigEndian 传NO就行 +(int16_t) int16FromBytes:(NSData *)data bigEndian:(BOOL)bigEndian { NSUInteger len = [data length]; Byte *by=(Byte *)malloc(len); memcpy(by, [data bytes], len); int16_t ret=((by[1] & 0xFF) << 8) + (by[0] & 0xff); if...

1、字符串转十六进制 代码实现: void StrToHex(char *pbDest, char *pbSrc, int nLen) { char h1,h2; char s1,s2; int i; for(i=0; i<nLen/2; i++) { h1 = pbSrc[2*i]; h2 = pbSrc[2*i+1]; s1 = toupper(h1) - 0x30; //toupper 转换为大写字母 ...
