提问by moon
I was to pass a NSString from RootViewController(UITableViewController) to DetailViewController .
我要从 RootViewController(UITableViewController) 传递一个 NSString 到 DetailViewController 。
t RootViewController.m
t RootViewController.m
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
DetailViewController *detailViewController = segue.destinationViewController;
detailViewController.name = @"foo";
}
DetailViewController.h:
DetailViewController.h：
NSString *name;
@property (nonatomic,strong) NSString *name;
DetailViewController.m
DetailViewController.m
@synthesize name = _name;
NSLog(@"%@", name);
The result of NSlog is null. Appreciate for any hint. Thanks a lot.
NSlog 的结果为空。感谢任何提示。非常感谢。

I can't really see when you are executing your nslog. So i'm thinking you ask for the name before you are setting it.
我真的看不到你什么时候执行你的 nslog。所以我想你在设置之前询问名称。
And another thing. If you write:
还有另一件事。如果你写：
@synthesize name = _name;
you should use this too:
你也应该使用这个：
NSLog(@"%@", _name);
