我有我的应用程序的RootViewController问题。当我运行应用程序时,我得到这个错误。这意味着什么?这个类不是关键值编码兼容的关键imageView
NSUnknownKeyException', reason: '[<UIApplication 0x8634010> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key bigImageView.'

我在RootViewController.h
#import <UIKit/UIKit.h>
@interface RootViewController : UIViewController <UIGestureRecognizerDelegate>{
}
@property (nonatomic, copy)IBOutlet UIImageView * bigImageView;
@property (nonatomic, assign)BOOL fromRootViewController;
- (void)handleTap:(UITapGestureRecognizer *)recognizer;
@end
我的代码代码RootViewController.m
#import "RootViewController.h"
#import "MenuViewController.h"
@interface RootViewController()
@end
@implementation RootViewController
@synthesize bigImageView;
@synthesize fromRootViewController;
- (void)viewDidLoad
{
[super viewDidLoad];
UIDeviceOrientation deviceOrientation = [[UIDevice currentDevice]orientation];
if(deviceOrientation == UIInterfaceOrientationPortrait || deviceOrientation== UIInterfaceOrientationPortraitUpsideDown) {
self.bigImageView= [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"milanocina_V.png"]];
}
else if (deviceOrientation== UIInterfaceOrientationLandscapeRight){
self.bigImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"milanocina_O.png"]];
}
else if (deviceOrientation==UIInterfaceOrientationLandscapeLeft){
self.bigImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"milanocina_O.png"]];
}
[self.view addSubview:self.bigImageView];
UITapGestureRecognizer * recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
recognizer.delegate = self;
[self.view addGestureRecognizer:recognizer];
}
的RootViewController的最初名为ViewController中,我已经改了名字。可以与错误相关?我能做什么?
你有没有注意到错误消息说你试图在'UIApplication'上设置该属性......世界上所有的'RootViewController'中的代码都没有什么区别。我敢打赌,你的XIB文件中有一个错误的链接。不好的链接将显示很少解释点。 – borrrden
我如何找到错误的连接? –
我不知道这是否会导致您的问题,但是您对bigImageView做了错误处理。您将其定义为IBOutlet,然后将其分配给在代码中创建的实例。如果你用IB连接到你在那里的ImageView,那么代码将覆盖它。它可能不应该是一个IBOutlet,因为根据方向的不同,你需要它是不同的东西。 – rdelmar
