我想通过A级到B级的阵列,但A电话是B。

Answer 1

What you want are simple object members to set. The best way to achive this is to use properties: http://developer.apple.com/library/ios/#referencelibrary/GettingStarted/Learning_Objective-C_A_Primer/_index.html#//apple_ref/doc/uid/TP40007594

页: 1 B.h:

@property(nonatomic,retain) NSArray * theArray_B;

页: 1

@synthesize theArray_B;

页: 1

myB_Instance.theArray_B = theArrayToPass;

在这种例子中,A和B与同一记忆中的阿雷-奥目标有着共同点。此外,B拥有这个Array(A也是这样),因为它有保留。

Answer 2

与此类似:

A类:

- (void)someMethodInClassA {
    NSArray *arrayData = // ... stuff

    ClassB *classB = // ... stuff

    [classB aMethod:arrayData];

}

B类:

- (void)aMethod:(NSArray *)array {
    // do something with the array
}

Answer 3

使用。

a. 编组,使其财产归为一体。然后推向下观点,然后将从航站的 pick子用于排入阵列。参看这一点。

 FirstView *obj=(FirstView *)[self.navigationController.viewControllers objectAtIndex: [self.navigationController.viewControllers count]-2];

 //obj.array is the array which you want to use.
