我已尝试过在视图控制器之间传递此数据的所有方法,两者都以模式方式表示为页面。
ViewController 1 .h 中的----------
@property (strong, nonatomic) NSMutableDictionary * updatableProduct ;
//@property (strong, nonatomic) NSDictionary * updatableProduct ; //tried
ViewController 1 .m 中的----------
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString * cellIdentifier = @"Cell";
TailorOUCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];
cell.updateOrder.tag = indexPath.row;
[cell.updateOrder addTarget:self action:@selector(nowUpdateOrder:) forControlEvents:UIControlEventTouchUpInside];
orderToUpdate = [orderQueryResults objectAtIndex:indexPath.row];
return cell;
}
-(void)nowUpdateOrder:(id)sender{
UIButton *senderButton = (UIButton *)sender;
updatableProduct = [orderQueryResults objectAtIndex:(long)senderButton.tag];
[self performSegueWithIdentifier:@"updateOrder" sender:updatableProduct];
//[self performSegueWithIdentifier:@"updateOrder" sender:self]; //tried
}
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if ([segue.identifier isEqualToString:@"updateOrder"]) {
OUEditView * ouv = (OUEditView *)segue.destinationViewController;
ouv.orderDetails = updatableProduct;
[segue.destinationViewController setModalPresentationStyle:UIModalPresentationPageSheet];
}
}
ViewController 2中的.h ----------
@property (strong, nonatomic) NSMutableDictionary * orderDetails ;
ViewController 2 .m 中的----------
@synthesize orderDetails;
但是日期中的orderDetails = null
任何帮助!

您需要在代码中添加断点或日志语句,看看发生了什么。
