發送附件到Salesforce通過iOS原生一個REST SDK

Question

我需要把我的形象在我的iphone app.I到Salesforce已經嘗試那些東西 轉換的圖像 - >字節 - > base64編碼然後存儲SFDC（豐富的數據字段），它是完全可以做到的，但我需要保存爲圖像。這裏是我的如下代碼（它不工作） 引導我如何實現這一

NSData *imageData = UIImagePNGRepresentation(imageView.image); 
    NSString *boundary = @"---------------------------14737809831466499882746641449"; 

    SFRestRequest *request = [[SFRestRequest alloc] init]; 
    [request setDelegate:self]; 
    [request setEndpoint:kSFDefaultRestEndpoint]; 
    [request setMethod:SFRestMethodPOST]; 
    NSMutableData *body = [NSMutableData data]; 
    [body appendData:[[NSString stringWithFormat:@"rn--%@rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:[NSString stringWithFormat:@"Content- Disposition: form-data; name=\"entity_document\"; filename=\"%@\"\r\n",@"Test.png"]] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[@"Content-Type: multipart/form-data\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:[NSString stringWithFormat:@"Description :\"%s\"\r\n","Marketing brochure for Q1 2011"]] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:[NSString stringWithFormat:@"Keywords :\"%s\"\r\n","marketing,sales,update"]] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:[NSString stringWithFormat:@"FolderId :\"%s\"\r\n","005D0000001GiU7"]] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:[NSString stringWithFormat:@"Name :\"%s\"\r\n","Marketing Brochure Q1"]] dataUsingEncoding:NSUTF8StringEncoding]]; 


    [body appendData:[NSData dataWithData:imageData]]; 
    [body appendData:[[NSString stringWithFormat:@"rn--%@--rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
    NSString *attbody = [NSString stringWithFormat:@"{\"body\" : {\"Name\" :[{ \"type\" : \"image/jpeg\", \"image\" : \"%@\"}] } }",body]; 

    [request setPath:[NSString stringWithFormat:@"/v23.0/sobjects/Document/"]]; 
    [request setQueryParams:(NSDictionary *)[SFJsonUtils objectFromJSONString:attbody]]; 
    [[SFRestAPI sharedInstance] send:request delegate:self]; 

有需要的任何類（APEX）處理我的請求？

Answer 1

我已經創建頂點其餘類收到的二進制數據，然後保存到SFDC（保存在文檔圖像）。這裏爲i稱爲教程。

而且這裏的教程如何通過我的ios訪問頂點web服務。

Answer 2

如果你只是想上傳的二進制數據，附件和/或文件，那麼你不應該需要在所有寫的Apex類，你應該能夠通過REST API做的一切。如圖鏈接的博客文章

的Apex類只是用於創建自定義Web服務。如果你願意，你可以選擇這條路線，但對於你試圖達到的目標來說絕對不是必需的。

的NSData * myData的= [[NSData的頁頭]的init]; //初始化與文件內容

NSString *b64 = [myData base64EncodedString]; 

NSDictionary *fields = @{ 
         @"Name": @"Document Name.ext", 
         @"Body": b64, 
         @"ParentId": recordId 
         }; 
attachmentRequest = [[SFRestAPI sharedInstance] requestForCreateWithObjectType:@"Attachment" fields:fields]; 

[[SFRestAPI sharedInstance] sendRESTRequest:attachmentRequest failBlock:^(NSError *e) { 
    NSLog(@"Error"); 
} completeBlock:^(id dict){ 
    NSLog(@"Uploaded"); 
}];

爲了使這樣的視圖功能，Salesforce的適用於圖像附件你也想要ContentType字段的管理GUI：

UIImage *testImg = [UIImage imageNamed:@"someImageName"]; 
NSData *testImgData = UIImagePNGRepresentation(testImg); 
NSString *b64 = [testImgData base64Encode]; // base64Encode declared in NSData+SFAdditions.h 

NSDictionary *fields = @{ 
         @"Name": @"someImage.png", 
         @"Body": b64, 
         @"ParentId": @"00Q50000016TuGIEA0", // of course put your Attachment Id here instead of mine 
         @"ContentType": @"image/png" 
         }; 
SFRestRequest *attachmentRequest = [[SFRestAPI sharedInstance] requestForCreateWithObjectType:@"Attachment" fields:fields]; 
[[SFRestAPI sharedInstance] send:attachmentRequest delegate:self];
