TTRequestLoader 最大内容大小问题答案

【问题描述】：

我在尝试使用 TTRequestLoader 加载大文件时遇到这些错误：

2011-06-30 07:25:21.782 xxxxxxx[1261:607] -[TTRequestLoader connection:didReceiveResponse:](317):
 TTDASSERT failed: 0 == _queue.maxContentLength || contentLength <=_queue.maxContentLength

是否有增加 TTURLRequest 加载的文件大小的功能，以避免这些错误？

我的代码：

TTURLRequest* request = [TTURLRequest
                       requestWithURL: [_url absoluteString]
                       delegate: self];

request.cachePolicy = cachePolicy;
request.cacheExpirationAge = (60*60*24*3);

TTURLDataResponse* response = [[TTURLDataResponse alloc] init];
request.response = response;
TT_RELEASE_SAFELY(response);

【解决方案1】：

断言上面有以下comment：

// If you hit this assertion it's because a massive file is about to be downloaded.
// If you're sure you want to do this, add the following line to your app delegate startup
// method. Setting the max content length to zero allows anything to go through. If you just
// want to raise the limit, set it to any positive byte size.
// [[TTURLRequestQueue mainQueue] setMaxContentLength:0]

所以调用[[TTURLRequestQueue mainQueue] setMaxContentLength:0] 应该可以。
