[問題] 兩個View傳值問題

[mew3133 (大雄)]

請問一下我這樣傳值哪裡有問題...QQ
我有兩個View 簡稱View1 &View2
再View2 的StroyBoard  ID 定義為“SystemView"
-----------------------------------------------
我在View1.h 宣告
@interface View1:UIViewCOntroller

@property (strong,nonatomic)View2 *view2;


@end
-----------------------------------------------
View2.h宣告一個變數

@interface View2 :UIViewController

@property int *number;

@end
-----------------------------------------------
View1.m 放入一個button 作為跳轉
- (IBAction)SystemSegue:(id)sender {
    self.view2.number=10;
    NSLog(@"self SysViewcontrlloer is %@",slef.view2.number);
        view2=[self.storyboard instantiateViewControllerWithIdentifier:@"SystemView"];
    [self presentViewController:view2 animated:NO completion:nil];

}

可是在View1 NSLog有數值
進入View2 時..number 值卻不見了...
我哪裡做錯了ＱＱ？

→ atst2:宣告為int * number? 然後用%@顯示?
→ atst2:改用@property (nonatomic, assign) int number試看看吧
→ howdiun:錯字好多.....
