几天前我写了一个使用presentViewController加载视图控制器的方法：
-(void)passaGC:(NSString *)user
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController *viewController = (UIViewController *)[storyboard instantiateViewControllerWithIdentifier:@"generaC"];
[self presentViewController:viewController animated:YES completion:nil];
}
但今天我需要将变量用户从此方法传递给加载的viewController.
我发现了堆栈溢出的其他问题,但没有什么与我的请求非常相似
解决方法
将属性添加到目标viewController(在.h中)：
@property (strong,nonatomic) NSString *user;
最后你的方法看起来像
-(void)passaGC:(NSString *)user
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController *viewController = (UIViewController *)[storyboard instantiateViewControllerWithIdentifier:@"generaC"];
viewController.user = user;
[self presentViewController:viewController animated:YES completion:nil];
}
