objective-c - 无法识别的选择器发送到实例，原因

Question

每当我打电话

self.gLViewController = [[GLViewController alloc] initWithNibName:@"GLViewController" bundle:nil];
       [self.navigationController pushViewController:self.gLViewController animated:YES]; 

我收到以下错误：

2012-06-06 15:22:50.329 NavApp[5357:707] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MiniGamesViewController setGLViewController:]: unrecognized selector sent to instance 0x1f6aa730'

terminate called throwing an exception(lldb) 

谁能帮我准确地告诉我这是在说什么？我已经为此工作了整整一个小时，但一无所获。非常感谢您的帮助！

您必须在MiniGamesViewController.m中合成该属性

//After the implementation
@implementation MiniGamesViewController
//Add this line
@synthesize gLViewController;
