У меня проблема с кодом, пожалуйста, помогите мне. Вот мой код.
printerView *pvvc=[[printerView alloc] init];
//[pvvc PrintImage:pvvc.printImageButton];
//[pvvc getCheckSum];
NSMutableArray *arrOrderVal=[pvvc getCheckSum];
unsigned char buffer2[24];
buffer2[0] = 0X55; buffer2[1]=0x66; buffer2[2]=0x77; buffer2[3]=0x88; buffer2[4]=0x44;//print command
buffer2[5] = 0X1D; buffer2[6]=0x6B; buffer2[7]=02; buffer2[8]=0x0D;
//<set order data
int arrStart=9;
for (int i=0; i<13; i++) {
NSString *val=[arrOrderVal objectAtIndex:i];
buffer2[arrStart+i]=([val intValue]+30);//[NSString stringWithFormat:@"0x%d",([val intValue]+30)];
}
//</set order data
/*buffer2[9] = 0X35; buffer2[10]=0x30; buffer2[11]=0x30; buffer2[12]=0x30; buffer2[13]=0x33;
buffer2[14] = 0X35; buffer2[15]=0x37; buffer2[16]=0x37; buffer2[17]=0x30; buffer2[18]=0x33;
buffer2[19] = 0X30; buffer2[20]=0x31; buffer2[21]=0x38; */
buffer2[22]=0x37; buffer2[23]=0x30;
for (int i=0; i<24; i++) {
NSLog(@"%c",buffer2[i]);
}
Я хочу динамически добавлять значения для этого массива. значения в том же формате, что я прокомментировал.
but this printing it empty values. as below.
