存储图像数组后应用程序崩溃

Question

我正在从以下代码中获取屏幕截图：

CGImageRef cgScreen = UIGetScreenImage();
    if (cgScreen) {
        UIImage *result = [UIImage imageWithCGImage:cgScreen];
        CGImageRelease(cgScreen);
        return result;
    }

我在 1/1.0 秒的计时器中调用上述代码：

[array addObject:[UIImage imageWithScreenContents]];

imagewithScreenContents 是一个函数。 但几秒钟后，即添加 90 帧后应用程序崩溃。 我无法理解这个问题。 谁能帮我解决这个问题。

以下是崩溃日志报告：- 事件标识符：C2EE3C76-1467-4578-BCFE-A29C1F0008A6 CrashReporter 密钥：66bc0900aa035a62f27c2c26fe3f6f3f1b8e7301 过程：VideoRecorderProject [98] 路径：/var/mobile/Applications/37935917-FB62-48D4-9DF8-AC5D897C137F/VideoRecorderProject.app/VideoRecorderProject 标识符：VideoRecorderProject 版本： ？？？ （？？？） 代码类型：ARM（本机） 父进程：debugserver [97]

您不得发布UIGetScreenImage();获取的图像。有关详细说明，请参阅here。这很可能是 EXC_BAD_ACCESS 的原因。
