How big are the images? And how many are you trying to send?
I can't seem to find an easy way to implement an NSInputStream using AFNetworking, but there's definitely one thing you should try, which is avoiding putting big objects in the autorelease pool. When you are creating big NSData instances insinde a for loop, and those are going to the autorelease pool, all that memory sticks around for as long as the loop lasts. This is one way to optimize it:
for (int i=0; i<[self.sImages count]; i++) {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSData *imageData = UIImageJPEGRepresentation([self.sImages objectAtIndex:i], 0.7);
[formData appendPartWithFileData:imageData name:@"pics[]" fileName:@"avatar.jpg" mimeType:@"image/jpeg"];
pool drain];
}
Or, if you're using LLVM3:
for (int i=0; i<[self.sImages count]; i++) {
@autoreleasepool {
NSData *imageData = UIImageJPEGRepresentation([self.sImages objectAtIndex:i], 0.7);
[formData appendPartWithFileData:imageData name:@"pics[]" fileName:@"avatar.jpg" mimeType:@"image/jpeg"];
}
}
