问题描述
我尝试在 SecondViewController 中创建如下方法:
I tried creating a method like below in SecondViewController:
-(void)setValue:(NSMutableArray*)array
{
//NSMutableArray *newArray = [[NSMutableArray alloc] init];
newArray = [array retain];
}
并使用名为 second 的 SecondViewController 对象从 FirstViewController 传递值:
and passing the value from FirstViewController using an object of SecondViewController named second:
[second setValue:existingArray];
existingArray 是一个 NSMutableArray.
existingArray is an NSMutableArray.
可能出了什么问题?
推荐答案
在代码中，您在 SecondViewController 的second"对象中设置了数组.
In the code you have set the array in the "second" object of a SecondViewController.
所以你需要使用那个对象来显示 SecondeViewController，否则它怎么可能不显示数组.
So you need to use that object for displaying the SecondeViewController, other wise how can it won't show the array.
检查以下代码.
// In the FirstViewController
- (void)buttonClicked:(id)sender{
SecondViewController *second = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle: nil];
[second setValue:existingArray];
[self.navigationController pushViewController:second animated:YES];
[second release];
}
在代码中，我将数据分配给第二个"对象中的数组，并使用该对象来显示控制器.
Here in the code I am assigning the data to the array in the "second" object and I am using that object to display the controller.
