提问by Kiran Aftab
I want to send the myNumber values to the next controller in iphone app as normaaly do for NSString i am doing like this but it is not working
我想将 myNumber 值发送到 iphone 应用程序中的下一个控制器，就像通常为 NSString 所做的那样，我正在这样做，但它不起作用
int mynumber=100;
NextViewController*targetController=[[NextViewController alloc]init];
targetController.mynumber=mynumber;
[self.navigationController pushViewController animated:YES];
NextViewController
下一个视图控制器
int mynumber;
Implementation NextViewController
实现 NextViewController
int mydata=mynumber;

In you NextViewController.hfile declare a propertyof type intwith var name mynumberlike this -
在你的NextViewController.h文件中声明一个property类型int为 var 名称的类型mynumber-
NextViewController.h
@property (nonatomic) int mynumber;
then synthesizeit in NextViewController.m
然后synthesize它在NextViewController.m
NextViewController.m
@synthesize mynumber;
now you can assignit as you are doing;
现在你可以assign做你想做的了；

In NextViewControllermake property of integer and synthesize it.
在NextViewController整数的 make 属性中并合成它。
@property(nonatomic) NSInteger mynumber;
@synthesize mynumber;
then
然后
int mynumber=100;
NextViewController *targetController=[[NextViewController alloc]init];
targetController.mynumber=mynumber;
[self.navigationController pushViewController:targetController animated:YES];

You need to set the property in NextViewController.h first:
您需要先在 NextViewController.h 中设置属性：
@property NSInteger mynumber;
And in NextViewController.m:
在 NextViewController.m 中：
@synthesize mynumber;
Your code will work after these steps.
您的代码将在这些步骤后工作。

I your AppDelegate.mcreate int dataString;as a global variable. Now use it to pass data from one View to another by adding your code to your firstView like int FirstViewData = dataString;Now Call it in your Second View similarly.
我AppDelegate.m创建int dataString;为全局变量。现在使用它通过将代码添加到您的 firstView 来将数据从一个 View 传递到另一个 View，就像int FirstViewData = dataString;Now Call it in your Second View 类似。
