Application's Document folder in iphone

问题

I am using dropbox API and downloading file in application document folder.

I am able to view list of files in table from document directory. How can I read photos or file from this table view?

And what about the iPhone. Can we access document folder directly?

回答1:

This is the more commonly used approach to get the documents directory –

NSArray *searchResults = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [searchResults objectAtIndex:0];

NSString *filePath = [documentsDirectory stringByAppendingPathComponent:fileName];

You can use NSFileManager to examine the contents of the directory. You can look at the contentsOfDirectoryAtPath:error: method.

回答2:

Access document Folder -

NSDictionary *theCatalogInfo=nil;
NSString *theCatalogFilePath = [NSString stringWithFormat:@"%@/Documents/",NSHomeDirectory()];
theCatalogFilePath = [theCatalogFilePath stringByAppendingString:@"File Name"];
if(nil!=theCatalogFilePath)
{


    theCatalogInfo=[[NSDictionary alloc]initWithContentsOfFile:theCatalogFilePath];

}

return theCatalogInfo;
