Hi, Code: char string1 = "Hello"; NSString* string = @"World!"; NSString* string2 = (NSString*)string1; string2 = [string stringByAppendingString:string2]; NSLog(@"string:%@",string2); I have to append the strings. One is of c-type and the other is of NSObject type. How to append these two strings.I tried to append two NSStrings and I got the output. I'm getting an EXC_BAD_ACCESS when tried to execute the above code. How to make the char as an NSObject type.
