Question

我正在尝试将NSDictionary从UIViewcontroller转移到UIView 字典包含多边形的x和y值 Uiview将绘制此多边形我的问题是UIViewcontroller上存在x y值，
它们到达Uiview的initWithFrame，
但无法在Uiview中达到drawRect 请帮我。

#import "ViewController.h"
#import "circles_3.h"
#import "draw.h"

@implementation ViewController

@synthesize Core;

- (void)viewDidLoad
{

[super viewDidLoad];
int i;

// Returns NSMutable dictionary with x y points of polygons, some nsstrings and some colors
circles_3 *geo = [circles_3 alloc];
self.Core=[geo updatenum:self.Core];


// Count number of Patches
NSUInteger numObjects = [[self.Core valueForKeyPath:@"Data"] count];

NSArray* filtered=[Core objectForKey:@"Data"];

// Pointer to the UIview class
draw *patch;

// Iterate for all the polygons
for (i=0;i<numObjects;i++)
{
    NSDictionary *data = [filtered objectAtIndex:i];

    // Sent the data to the draw class for plotting
    patch = [[draw alloc] initWithFrame:[[UIScreen mainScreen] bounds] data :data];

    [self.view addSubview:patch];

}
}
@end









 #import <UIKit/UIKit.h>
 #import "ViewController.h"
 #define ARC4RANDOM_MAX      0x100000000
 @interface draw : UIView
  @property  NSDictionary * data;
  - (id)initWithFrame:(CGRect)frame data:(NSDictionary *)Core;
   @end

UIview类

 #import "draw.h"

  @implementation draw

  @synthesize data;

  - (id)initWithFrame:(CGRect)frame data:(NSDictionary *)Core;
 {
     self = [super initWithFrame:frame];

     if (self)
      {
         self.data=Core;
       }
     return self;
   }

  - (void)drawRect:(CGRect)rect
 {

   // In here i get nil for
    self.data
   ???????????????
    }

将数据（NSdictionary）从UIviewcontroller传递到UIview
