我試圖從iPhone上傳攝像機圖像到我的網絡服務器，但一些圖像如何改變它的方向，當我從服務器上下載它們時。這隻發生在相機圖像上，而不是簡單的圖像上傳從我的機器到設備。Plz幫助我。iphone圖像從服務器下載時得到旋轉
我有使用該條件對服務器側旋轉圖像：
//物鏡將被取向通過在上載服務器上的圖像將其值是1或-3或6或8
switch ((ushort)obj)
{
case 1: //up
return 0;
case 3: //down
return 180;
case 6: //left
return 90;
case 8: //right
return 270;
default:
return 0;
}
不過還是我得到了同樣的問題
這裏是我的上傳圖片代碼：
-(void)uploadSingleFile
{
if(!self.objWebServices.bSyncWasOn)
{
NSLog(@"STOP upload Single File RETURN");
[self Call_SaveSyncedImageID];
return;
}
SyncItem* item = [arrSelSyncItemIDS objectAtIndex:nSyncItemIndex];
if(item.nType == SYNC_STATUS_NOT_SELECTED || item.nType == SYNC_STATUS_SYNC_DONE)
{
nSyncItemIndex = nSyncItemIndex + 1;
if([arrSelSyncItemIDS count] > nSyncItemIndex)
{
NSLog(@"Called uploadSingleFile");
[self uploadSingleFile];
return;
}
else
{
//[self LoadImages:!bShowHideSyncImages];
[SVProgressHUD dismiss];

什麼樣的對象是'obj'？顯示更多的代碼，否則你永遠不會得到有用的答案。 – NSAddict
你可以把你的代碼上傳圖片，所以我們可以更明白..可能是什麼問題？ – SachinVsSachin
