请移除EasyNavigationController中对于-setTitle:的重写

[Hsukun]

//- (void)setTitle:(NSString *)title
//{
// if (self.topViewController.navigationView) {
// [self.navigationView setTitle:title];
// }
//}

或将 ‘ self.topViewController.navigationView’ 的判断条件改为：self.topViewController.navigationController, 因为self.topViewController 拿回来的可能是 UINavigationController，且当 navigationController 为空时，获取navigationView时就会被NSAssert拦截，此判断根本无效：

if (!self.navigationController) {
NSAssert(NO, @"attention: this controller's navigationcontroller is null: %@",self);
}
