自昨天升级到Lion(10.6-> 10.7)以来,我一直无法编译在升级之前编译没有问题的项目.

这个项目最近的变化甚至不会导致这个错误:如果我从几天或一周前从SVN签出一个项目版本,我在构建时会遇到同样的错误:

"Command /Developer/usr/bin/momc failed with exit code 6",扩展到以下内容:

构建错误:

使用ASIFormDataRequest将文件上传到服务器时非常奇怪(对我而言).

通过WiFi上传时,没有问题,我可以上传就好了.使用O2 UK作为运营商通过3G上传时,也没有问题.当我使用完全相同的代码使用Vodafone UK上传相同的服务器时,HTTP请求到达服务器并且POST内容被剥离.如果我尝试相同的请求但没有上传图像(只需添加test => yes作为一些POST数据),那么这将有效,但是如果我有test => yes并附加一个文件,它会通过POST到达服务器数据被剥离了.

NB我在iPhone 4S上使用最新版本的ASIHTTPRequest,并且可以在使用Vodafone UK和O2 UK的其他几款手机上进行各种再现.

所以,我将我的objc代码指向以下PHP脚本,它只打印出它收到的内容:

<?php
error_reporting(E_ALL);
ini_set("display_startup_errors","1");
ini_set("display_errors","1");

echo "FILES: ".print_r($_FILES,true);
echo "POST: ".print_r($_POST,true);
echo "GET: ".print_r($_GET,true);

die('done.');

我正在使用的obj-c代码是:

- (void)viewDidLoad
{
    [super viewDidLoad];

    NSURL *url = [NSURL URLWithString: @"http://myserver.com/debugger.php"];
    ASIFormDataRequest *request = [[ASIFormDataRequest alloc] initWithURL:url];

    [request setDelegate:self];
    [request setDidFinishSelector:@selector(networkRequestSuccess:)];
    [request setDidFailSelector:@selector(networkRequestFailure:)];
    [request setTimeOutSeconds:120];

    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"smalltestimage" ofType:@"png"];  
    NSData *myData = [NSData dataWithContentsOfFile:filePath];  
    if (myData) {  
        [request addPostValue:@"Yes" forKey:@"Test"];
        [request addData:myData withFileName:@"smalltestimage.png" andContentType:@"image/png" forKey:@"photos"];
        [request startSynchronous];
    }
