iphone - 如何在派生类中分配全局 NSInteger 对象

Question

//AppDelegate.h
AppDelegate NSInteger myInt;
@property (readwrite, assign) NSInteger myInt;

//AppDelegate.m
@synthesize myInt;


//MyClass.h

AppDelegate *objAppDelegate;

//MyClass.m

objAppDelegate =  (AppDelegate *) [[UIApplication sharedApplication] delegate];

当我尝试为 myInt 赋值时

objAppDelegate.myInt=(NSInteger *)0; // <--- this gives warning: something like incompatible pointer to integer conversion like that 

那么，我该如何分配这个变量呢？

Answer 1

objAppDelegate.myInt = (NSInteger)0;

或

objAppDelegate.myInt = 0;

您应该在没有指针的情况下分配给 NSInteger。
