Question

我在iOS上面临org.apache.cordova.camera r0.3.5的问题。 r0.3.4对我来说一切正常。我试图拍照时应用程序崩溃了。请查看导致问题的行。

我遇到了同样的问题。我调试了一下，问题出在CDVCamera.m文件中。在第170行，您有以下代码

[weakSelf.viewController presentViewController:cameraPicker animated:YES completion:^{
    weakSelf.hasPendingOperation = NO;
}];

应该在主线程中调度整个调用。我认为这在以后的版本中已得到修复，但如果您想要快速修复，请执行以下操作

dispatch_async(dispatch_get_main_queue(), ^{
    [weakSelf.viewController presentViewController:cameraPicker animated:YES completion:^{
         weakSelf.hasPendingOperation = NO;
    }];
});

所以简而言之，您可以选择新版本，即r0.3.6，或者您可以自行更改。万一你不知道你会在＆＃34; org.apache.cordova.camera＆＃34;下的插件文件夹中找到这个文件。夹。干杯!!
