在视图控制器之间传递变量 [英] Passing variables between view controllers

问题描述

我正在使用此函数在Xcode 4.3中切换视图。

  [self performSegueWithIdentifier：@NextView发件人：自]; 
  

我想在页面之间传递一些参数。我怎么能这样做？

解决方案

在之后执行SegueWithIdentifier：sender：你的view controler将调用

   - （void）prepareForSegue：（UIStoryboardSegue *）segue发送者：（id）sender 
 <假设您的新视图控制器设置了一些属性：/ $ c 
 $ b 
  if（[[segue identifier] isEqualToString：@NextView]）{
 MyViewController * myVC = [segue destinationViewController]; 
 myVC.propertyToSet = //在此处设置您的房产
} 
  
 
I am using this function to switch between views in Xcode 4.3.
[self performSegueWithIdentifier:@"NextView" sender:self];
I would like to pass some parameters between pages. How can I do that?
解决方案
After performSegueWithIdentifier:sender: your view controler will call
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
assuming your new view controller has some propertys to set:
if ([[segue identifier] isEqualToString:@"NextView"]) {
    MyViewController *myVC = [segue destinationViewController];
    myVC.propertyToSet = // set your properties here
}
