How to upload image, which is not saved on the device to the dropbox account?(IOS)

问题

Dropbox restClient saves only files. So i want to save the image in local folder first and then to upload it, as a result it saves file, but it is corrupted.

NSString *localPath = [[NSBundle mainBundle] pathForResource:@"Info" ofType:@"plist"];
NSString *jpegFilePath = [NSString stringWithFormat:@"%@/test.jpeg",localPath];
NSData *data2 = [NSData dataWithData:UIImageJPEGRepresentation(image, 1.0f)];
[data2 writeToFile:jpegFilePath atomically:YES];

NSString *filename = @"test.jpeg";

NSString *destDir = @"/";
[[self restClient] uploadFile:filename toPath:destDir
                withParentRev:nil fromPath:localPath];

I am an idiot, solved

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *path = [[paths objectAtIndex:0] stringByAppendingString:@"test.jpg"];

NSData * data = [NSData dataWithData:UIImageJPEGRepresentation(image, 1.0f)];
[data writeToFile:path atomically:YES];
[self.restClient uploadFile:@"test.jpg" toPath:@"/" withParentRev:nil fromPath:path];

回答1:

you will have to call DBRestClient methods from the main thread or a thread that has a run loop. Otherwise the delegate methods will not be called.

what you will have to do is first alloc init yoir DBRestClient object then make it's delegate self and then you can easily upload your file.below is an example

NSString *destDir = @"/";
restClient = [[DBRestClient alloc] initWithSession:[DBSession sharedSession]];
restClient.delegate = self;

[restClient uploadFile:yourfilename toPath:destDir withParentRev:nil fromPath:sourcepath];

Happy Coding!!!!!!

You can't save into the bundle. You should use documents or cache folder:

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