ios - Meaning of warning "Class implementation may not have super class" -


i have created basic objective-c class.

myclass.h

@interface myclass: nsobject @end

myclass.m

#import "myclass.h" @interface myclass() @end  @implementation myclass: nsobject  {     nsmutablearray* _myarray; } @end

xcode showing following warning on @implementation line:

class implementation may not have super class

the warning goes away if remove nsmutablearray* _myarray; line.

what warning mean? doing wrong?

delete nsobject in implementation part. super class has specified in interface.

@implementation myclass {     nsmutablearray* _myarray; } @end

java - Callback from new thread to class from which thread was initiated -

i have class calling new thread. public class mainclass{ private void cleardata() { // on separate thread new thread(new runnable() { @override public void run() { //do //after notify mainclass thing has been done , pass value. } } } private void callbackfunc(int a){ // based on value of } } i have function in mainclass. how call function new thread, receive callback. thanks. you should able call method in mainclass name if calling directly inside mainclass (as opposed inner class). if method name want call happens conflict 1 inner class has inherited object can prefix call mainclass.this , e.g. mainclass.this.tostring() calls tostring on mainclass , whereas tostring() calls on inner class instance.
