我已经尝试了在视图控制器之间传递这些数据的所有方法,这两种方法都以模态方式表示为页面表。
在 ViewController 1 .h —————————</p>
@property (strong, nonatomic) NSMutableDictionary * updatableProduct ;
//@property (strong, nonatomic) NSDictionary * updatableProduct ; //tried
在 ViewController 1 .m ———————————</p>
-(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];
}
}
在 ViewController 2 .h —————————</p>
@property (strong, nonatomic) NSMutableDictionary * orderDetails ;
在 ViewController 2 .m ———————————</p>
@synthesize orderDetails;
但是日志中的 orderDetails = null
任何帮助!
