如何通過HTTP POST發送圖像數據？通過HTTP POST發送圖像數據
我有以下代碼：要做到這一點是通過做多圖片上傳但是這不會是JSON格式
NSURL *aUrl = [NSURL URLWithString:@"http://demo25.projectproofonline.com/soul_mate_modified/save.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:aUrl
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
[request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPMethod:@"POST"];
[NSURLConnection connectionWithRequest:request delegate:self];
