我遇到了一個問題,我試圖查看本地存儲的文檔(Word文檔,圖像或視頻)。我使用的是UIWebView,在模擬器上它可以很好地工作,但在設備上,它是一個空白屏幕(在控制檯中沒有錯誤)。這裏是我的代碼來查看文檔:UIWebView在模擬器上顯示本地存儲的文檔,但不顯示設備
UIWebView *newWebView;
if (appDelegate.IS_IPAD)
{
newWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 768, 1024)];
}
else
{
newWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
}
newWebView.scalesPageToFit = YES;
[self setWebView: newWebView];
[newWebView release], newWebView = nil;
[[self webView] setDelegate: self];
[[self view] addSubview:[self webView]];
NSURL *nsURL = [NSURL fileURLWithPath:filePath isDirectory:NO];
[[self webView] loadRequest:[NSURLRequest requestWithURL:nsURL]];
這是我如何在查看本地保存文檔之前。我確實認爲該文件已成功保存在設備上,就像它在模擬器上一樣。
// Save the file on the device
NSURL *contentUrl = [NSURL URLWithString:selectedContent.contentUrl];
NSString *fileName = [[contentUrl absoluteString] lastPathComponent];
NSString *homeDirectoryPath = NSHomeDirectory(); // Create the path
NSString *unexpandedPath = [homeDirectoryPath stringByAppendingString:@"/MyApp/"];
NSString *folderPath = [NSString pathWithComponents:[NSArray arrayWithObjects:[NSString stringWithString:[unexpandedPath stringByExpandingTildeInPath]], nil]];
NSString *unexpandedImagePath = [folderPath stringByAppendingFormat:@"/%@", fileName];
NSString *filePath = [NSString pathWithComponents:[NSArray arrayWithObjects:[NSString stringWithString:[unexpandedImagePath stringByExpandingTildeInPath]], nil]];
if (![[NSFileManager defaultManager] fileExistsAtPath:folderPath isDirectory:NULL])
{
[[NSFileManager defaultManager] createDirectoryAtPath:nil withIntermediateDirectories:NO attributes:nil error:nil];
}
// Do the actual write of the file to the device
NSData *fileData = [NSData dataWithContentsOfURL:myUrl]; // Create the file data reference
[fileData writeToFile:filePath atomically:YES]; //Save the document to the home directory
謝謝,我敢肯定,因爲我使用「文件路徑」中--- [NSURL fileURLWithPath值完全相同它不能區分的問題: filePath isDirectory:NO]; ---就像我在本地保存內容時一樣。我甚至已經打印出NSLog中filePath的值,並且就情況而言看起來很好。除了大小寫之外還有什麼要注意的? – Phamer
