如何將NSMutableDictionary從一個viewController傳遞到另一個View控制器？

Question

firstviewcontroller.m

@property (nonatomic) NSMutableDictionary *json; 

.h 
@synthesis json; 

    viewdidload() 

    { 
     nslog(@"%@",json); 
    } 

secondviewcontroller.h

firstviewcontroller *FVC = [[firstviewcontroller alloc]init]; 

FVC.json = @"My NSMutableDictionary" 

這是我的代碼，在firstviewcontrolNSMutableDictionary值爲null。如何解決這個問題？

Answer 1

寫在你的"secondViewConroller.h"文件

@property (nonatomic, Strong) NSMutableDictionary *json; 

而且把它作爲在"firtstViewConroller.m"

NSMutableDictionary *temJSONDic = .... 

secondViewConroller *FVC = [[secondViewConroller alloc] initWithNibName:@"secondViewConroller" bundle:nil]; 
FVC.json = temJSONDic; 
[self.navigationController pushViewController:FVC animated:YES];

下面的代碼用來加載使用[NSBundle mainBundle]方法和返回數組的第一個對象的廈門國際銀行文件是控制器。然後分配您的字典對象，然後使用navigationcontroller推送。

NSArray * array = [[NSBundle mainBundle] loadNibNamed:@"<your xib file name without .xib extension>" owner:self options:nil]; 
secondViewConroller *cntrl = [array objectAtIndex:0]; 
cntrl.json = <your dictionary data>; 
[self.navigationController pushViewController:cntrl animated:YES];
