無法從ASIHTTPRequest中的downloadDestination路徑訪問圖像

我正在將圖像下載到Iphone HomeDirectory中的特定文件夾，但無法訪問它，因爲它將圖像保存爲隨機生成的名稱。所以請幫助我如何在我的其他功能中正確訪問它們。其他功能無法從ASIHTTPRequest中的downloadDestination路徑訪問圖像

- (void)fetchURL:(NSURL *)url 
{ 
request1 = [ASIHTTPRequest requestWithURL:url]; 
NSString *str1 = [NSString stringWithFormat:@"savedImage%d",i1]; 
NSString *path = [self.documentsDirectoryPath stringByAppendingPathComponent:str1]; 
NSLog(@"saved image path %@",path); 
[request1 setDownloadDestinationPath:[[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] stringByAppendingPathComponent:@"1.png"]]; 
    //path]; 
//[request1 setTemporaryFileDownloadPath:[[[[NSBundle mainBundle] bundlePath] stringByDeletingLastPathComponent] stringByAppendingPathComponent:@"1"]]; 
[request1 setAllowResumeForFileDownloads:YES]; 
[request1 setDelegate:self]; 
[request1 setDidFinishSelector:@selector(URLFetchWithProgressComplete:)]; 
[request1 setDidFailSelector:@selector(URLFetchWithProgressFailed:)]; 
[request1 setDownloadDestinationPath:[[ASIDownloadCache sharedCache] pathToStoreCachedResponseDataForRequest:request1]]; 
[[ASIDownloadCache sharedCache] setShouldRespectCacheControlHeaders:NO]; 
[request1 startAsynchronous]; 

i1++; 

//[request1 setDownloadDestinationPath:[[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] stringByAppendingPathComponent:@"1.png"]]; 
//[request setDownloadProgressDelegate:imageProgressIndicator1]; 
//[self.networkQueue addOperation:request1]; 
}

ASIDownloadCache *cache = [[[ASIDownloadCache alloc] init] autorelease]; 

//NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDownloadsDirectory, NSUserDomainMask, YES); 
self.documentsDirectoryPath = NSHomeDirectory(); 
//[paths objectAtIndex:0]; 

[cache setStoragePath:self.documentsDirectoryPath]; 

NSLog(@"path %@",self.documentsDirectoryPath); 

    self.destinationPath = [documentsDirectoryPath stringByAppendingFormat:@"/Library/Caches/ASIHTTPRequestCache/SessionStore"]; 

    //NSString *PathStr = [NSString stringWithFormat:@"savedImage%d",i]; 
    //NSString *appFile = [self.destinationPath stringByAppendingPathComponent:PathStr]; 

    //NSString *path = [self.documentsDirectoryPath stringByAppendingPathComponent:PathStr]; 
    //NSLog(@"images path %@",path); 

    NSLog(@"Download Destination Path %@",[request1 downloadDestinationPath]); 
    imageView.image = [UIImage imageWithContentsOfFile:[request1 downloadDestinationPath]]; 
     //self.destinationPath]; 
     //[request1 downloadDestinationPath]]; 

    NSLog(@"Image %@ and %d",imageView.image,i);

看起來你有兩個呼叫setDownloadDestinationPath。第一個將路徑設置爲主目錄的子目錄，但第二個更改它（如documentation的緩存部分中所述）。你可以保存到任何地方，但不能同時保存。

爲什麼要設置下載路徑兩次？

[request1 setDownloadDestinationPath:[[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] stringByAppendingPathComponent:@"1.png"]]; 
    ... 
[request1 setDownloadDestinationPath:[[ASIDownloadCache sharedCache] pathToStoreCachedResponseDataForRequest:request1]];

而你爲什麼要設置下載到緩存的請求？你應該只有一個downloadDestinationPath。

我試圖評論一個請求，但仍然無法訪問存儲在downloadDestinationPath中的圖像，因爲它們使用不同的名稱和一些HTML文件保存，不知道它們來自哪裏。 – user366584 2011-01-11 10:38:02
