在iPhone上tumblr上传图片

Question

我很困惑这个问题很多天。在我的应用程序中，我需要在tumblr上传图片，我已经尝试过各种教程和更新，但是没有人在tumblr上发布图片。如果你已经完成了这个任务，请帮助我。

NSData *imageData = [NSData dataWithContentsOfFile:photo]; 
//stop on error 
if (!imageData) return NO; 

//Create dictionary of post arguments 
NSArray *keys = [NSArray arrayWithObjects:@"email",@"password",@"type",@"caption",nil]; 
NSArray *objects = [NSArray arrayWithObjects: 
        tumblrEmail, 
        tumblrPassword, 
        @"photo", caption, nil]; 
NSDictionary *keysDict = [[NSDictionary alloc] initWithObjects:objects forKeys:keys]; 

//create tumblr photo post 
NSURLRequest *tumblrPost = [self createTumblrRequest:keysDict withData:imageData]; 
[keysDict release]; 

//send request, return YES if successful 
NSURLConnection *tumblrConnection = [[NSURLConnection alloc] initWithRequest:tumblrPost delegate:self]; 
if (!tumblrConnection) 
{ 
    NSLog(@"Failed to submit request"); 
    return NO; 
} 
else 
{ 
    NSLog(@"Request submitted"); 
    receivedData = [[NSMutableData data] retain]; 
    [tumblrConnection release]; 
    return YES; 
} 

-(NSURLRequest *)createTumblrRequest:(NSDictionary *)postKeys withData:(NSData *)data 
{ 
//create the URL POST Request to tumblr 
NSURL *tumblrURL = [NSURL URLWithString:@"http://api.tumblr.com/v2/blog/kashifjilani.tumblr.com/posts"]; 
NSMutableURLRequest *tumblrPost = [NSMutableURLRequest requestWithURL:tumblrURL]; 
[tumblrPost setHTTPMethod:@"POST"]; 

//Add the header info 
NSString *stringBoundary = @"0xKhTmLbOuNdArY---This_Is_ThE_BoUnDaRyy---pqo"; 
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",stringBoundary]; 
[tumblrPost addValue:contentType forHTTPHeaderField: @"Content-Type"]; 

//create the body 
NSMutableData *postBody = [NSMutableData data]; 
[postBody appendData:[[NSString stringWithFormat:@"--%@\r\n",stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]]; 

//add key values from the NSDictionary object 
NSEnumerator *keys = [postKeys keyEnumerator]; 
int i; 
for (i = 0; i < [postKeys count]; i++) { 
    NSString *tempKey = [keys nextObject]; 
    [postBody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n",tempKey] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [postBody appendData:[[NSString stringWithFormat:@"%@",[postKeys objectForKey:tempKey]] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [postBody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
} 

//add data field and file data 
[postBody appendData:[@"Content-Disposition: form-data; name=\"data\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[postBody appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[postBody appendData:[NSData dataWithData:data]]; 
[postBody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]]; 

//add the body to the post 
[tumblrPost setHTTPBody:postBody]; 

return tumblrPost; 
}

这个工作对我来说：

NSData *imageData = UIImageJPEGRepresentation(yourUploadImage, 0.9); 
NSMutableURLRequest *aRequest = [[[NSMutableURLRequest alloc] init] autorelease]; 
[aRequest setURL:[NSURL URLWithString:@"https://www.tumblr.com/api/write"]]; 
[aRequest setHTTPMethod:@"POST"]; 
NSString *boundary = @"0xKhTmLbOuNdArY"; 
//NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"]; 
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; 
[aRequest addValue:contentType forHTTPHeaderField: @"Content-Type"]; 

/* 
now lets create the body of the post 
*/ 
NSMutableData *body = [NSMutableData data]; 
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 

[body appendData:[@"Content-Disposition: form-data; name=\"email\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:Tumblr_UserName_Here dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 

[body appendData:[@"Content-Disposition: form-data; name=\"password\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:Tumblr_Password_Here dataUsingEncoding:NSUTF8StringEncoding]]; 

[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] 
        dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"Content-Disposition: form-data; name=\"type\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"photo" dataUsingEncoding:NSUTF8StringEncoding]]; 

[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"Content-Disposition: form-data; name=\"data\"; filename=\"upload.jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"Content-Transfer-Encoding: image/jpg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:imageData]; 

[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 

if(comment available here) 
{ 
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] 
         dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[@"Content-Disposition: form-data; name=\"caption\"\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[commentString dataUsingEncoding:NSUTF8StringEncoding]]; 
} 

// setting the body of the post to the reqeust 
[aRequest setHTTPBody:body]; 
[NSURLConnection connectionWithRequest:aRequest delegate:self]; 

现在的NSURLConnection

- (void)connectionDidFinishLoading:(NSURLConnection *)connection 
{ 
    if(connection) 
    NSLog(@"Success"); 
    else 
    NSLog(@"Something Wrong"); 
} 

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error; 
{ 
    NSLog(@"%@",[error description]); 
}

我一直在为此而努力了很久也delegate，但我想通了，如何发布容易。 你可以看到我的post为这个答案。如果您有任何问题，我很乐意提供帮助。
