小编Ope*_*ive的帖子

在iOS中,我从当前的viewController弹出到前一个,但它不会进入dealloc.

这是因为还有另一个指向当前viewController的指针,在不同的viewController中还是在当前的viewController中？

这是我弹出前一个视图的地方:

- (IBAction)fileUploadCancelTouched:(UIButton *)sender {

    [self.fileToUpload cancel];

    [self.view hideToastActivity];
    [self.greenprogressBar removeFromSuperview];
    [self.subView removeFromSuperview];
    self.fileUploadCancelButton.hidden = YES;
    if (self.commandComeBackToFinalScreen == 1) {
        [self.navigationController popViewControllerAnimated:YES];
    }
}

这是我的dealloc功能:

- (void)dealloc {
    [[NSNotificationCenter defaultCenter] removeObserver:self];

    self.greenprogressBar = nil;
    self.fileUploadCancelButton = nil;
    self.fileToUpload = nil;
    [buttonHome_ release];
    [buttonTestMeAgain_ release];
    [buttonMarkMyTest_ release];
    [examId_ release];
    [sender_ release];
    self.ob = nil;
    [_fileUploadCancelButton release];
    [super dealloc];
}

我通过Synaptics Package manager安装了以下软件包来编译Opengl.

freeglut3 freeglut3-dev freeglut3-dbg libglew1.5 libglew1.5-dev libglu1-mesa libglu1-mesa-dev libgl1-mesa-glx libgl1-mesa-dev

这是我运行程序时的输出.

X请求失败的错误:GLXBadFBConfig

失败请求的主要操作码:156(GLX)

失败请求的次要操作码:34()

失败请求的序列号:42

输出流中的当前序列号:41

对此的输入

(lspci | grep VGA) ; \
(dpkg -l | egrep 'xorg-video|glx') ; \
(ls -l /usr/lib/xorg/modules/{drivers,extensions})

给出一个输出
