nsstring ChAr

char*转NSString: char *filename = "aaaa";NSString * strPath = [NSString stringWithUTF8String:filename];NSString转char*: NSString *filePath = "aaaaa";char * filePathChar = [filePath UTF8String];

typedef unsigned char BYTE 的意思 就是在这个说明以后就可以在程序中用BYTE 代替unsigned char了,这只是为了编写代码的方便而已!BYTE在这里还是一个类型,并不是一个变量,里面没有存储东西。你可以 BTYE ar=‘a’,这时候变量ar中存储的就是字...

NSString* arr; char* brr = "123"; arr = [NSString stringWithFormat:@"%s",brr]; NSLog(@"%@",arr); 上面是char*变nsstring的方法,没见过nsstring变char*的

[mw_shl_code=c,true] NSString *myString = @"helloWorld我"; const char *stringAsChar = [myString cStringUsingEncoding:[NSString defaultCStringEncoding]]; // stringAsChar=null NSLog(@"stringAsChar=%s %s", stringAsChar, [myString ...

方法如下: 通过sscanf()函数得到int类型16进制数的值; 代码: int color; NSString *color_string = @"0xff0000"; char *color_char = [color_string cStringUsingEncoding:NSASCIIStringEncoding]; sscanf(color_char,"%x",&color); NSLog(@"...

char achar[1024];NSString *string = [[NSString alloc] initWithCString:(const char*)achar encoding:NSASCIIStringEncoding];试试这样

您好: NSString *strNSString; const char *pConstChar; strNSString = [[NSString alloc] initWithUTF8String:pConstChar]; pConstChar = [strNSString UTF8String];

char*转NSString: 1 2 char *filename = "aaaa"; NSString * strPath = [NSString stringWithUTF8String:filename]; NSString转char*: 1 2 NSString *filePath = "aaaaa"; char * filePathChar = [filePath UTF8String];

Char数组与NSString之间可以通过stringWithCString:encoding和 cStringUsingEncoding:来转换,但是最近在工作中发现将一个unsigned char数组(里面存储的是十六进制的数据)转化成NSString时,得到的结果有些数据却不正确,当然再将NSString转化...

如果是 .m文件,直接可以转换char *s;NSString *str;s=[str UTF8String];str=[NSString stringWithUTF8String:s];str=[NSString stringWithFormat:@"%s",s];如果是.mm会提示出错,因为[str UTF8String]返回的是c*****t char *
