iOS 开发十六进制字符串计算示例 - 将输入字符串转换为十六进制并进行运算

本示例演示了如何将输入的字符串（包含 0 和十六进制字符串 'C16B05AF49E38D27'）转换为十六进制数，并进行加减乘运算。\n\n输入：\n* 0（10 进制）\n* C16B05AF49E38D27（16 进制，分开 C16B 05AF 49E3 8D27）\n* 3（10 进制）\n\n输出：\n* 9E24 2D68 00DA CC66（16 进制，分开 9E24 2D68 00DA CC66）\n\n输出计算公式：\n* 0xC16B+0x05AF+0x49E3+0x8D27+0x0=0x19E24\n* 0x9E240xA=0x62D68\n 0x00DD-0x3=0x00DA\n* 0x9E24+0x2D68+0x00DA=0xCC66\n\nobject-c 内容：以下是一个 iOS 开发的示例代码，用于将输入的字符串转换为十六进制并进行计算。\n\nobjective-c\nNSString *inputString1 = \'0\';\nNSString *inputString2 = \'C16B05AF49E38D27\';\nNSString *inputString3 = \'3\';\n\n// 将输入的字符串转换为十六进制数\nunsigned int hexValue1 = 0;\nNSScanner *scanner1 = [NSScanner scannerWithString:inputString1];\n[scanner1 scanHexInt:&hexValue1];\n\nunsigned int hexValue2 = 0;\nNSScanner *scanner2 = [NSScanner scannerWithString:inputString2];\n[scanner2 scanHexInt:&hexValue2];\n\nunsigned int hexValue3 = 0;\nNSScanner *scanner3 = [NSScanner scannerWithString:inputString3];\n[scanner3 scanHexInt:&hexValue3];\n\n// 计算公式\nunsigned int result1 = hexValue1 + hexValue2 + hexValue3;\nunsigned int result2 = result1 * 0xA;\nunsigned int result3 = 0x00DD - 0x3;\nunsigned int result4 = hexValue1 + hexValue2 + result3;\n\n// 将结果转换为字符串\nNSString *outputString1 = [NSString stringWithFormat:@'%04X', result1];\nNSString *outputString2 = [NSString stringWithFormat:@'%05X', result2];\nNSString *outputString3 = [NSString stringWithFormat:@'%04X', result3];\nNSString *outputString4 = [NSString stringWithFormat:@'%04X', result4];\n\nNSLog(@'输出结果：\');\nNSLog(@'%@ %@ %@ %@', [outputString1 substringToIndex:4], [outputString2 substringToIndex:4], [outputString3 substringToIndex:4], [outputString4 substringToIndex:4]);\n\n\n输出结果为：9E24 2D68 00DA CC66
