我的应用程序的RootViewController有问题.当我运行应用程序时,我收到此错误.这意味着什么？
NSUnknownKeyException',reason: '[<UIApplication 0x8634010> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key bigImageView.' First throw call stack: (0x1992012 0x1357e7e 0x1a1afb1 0xe04711 0xd85ec8 0xd859b7 0xdb0428 0x4bc0cc 0x136b663 0x198d45a 0x4babcf 0x4bc98d 0x29eceb 0x29f002 0x29ded6 0x2af315 0x2b024b 0x2a1cf8 0x1dbedf9 0x1dbead0 0x1907bf5 0x1907962 0x1938bb6 0x1937f44 0x1937e1b 0x29d7da 0x29f65c 0x2c6d 0x2b95) libc++abi.dylib: terminate called throwing an exception
我在RootViewController.h中的代码
#import <UIKit/UIKit.h>
@interface RootViewController : UIViewController <UIGestureRecognizerDelegate>{
}
@property (nonatomic,copy)IBOutlet UIImageView * bigImageView;
@property (nonatomic,assign)BOOL fromRootViewController;
- (void)handleTap:(UITapGestureRecognizer *)recognizer;
@end
我在RootViewController.m中的代码
#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];
}
RootViewController最初调用了ViewController,我更改了名称.可以与错误相关联吗？我能做什么？
