iOS5 ARC errors: SKPSMTPMessage - ios5

Question

I'm attempting to incorporate this bit of code into a new(iOS 5) project... Problem is, I'm using ARC and it REALLY doesn't like the code as written.
I've been able to resolve most of the errors, but I'm stuck with 3 errors I can't seem to figure out.
Error #1:
Existing ivar 'delegate' for unsafe_unretained property 'delegate'
must be _unsafe_unretained
.h
#interface SKPSMTPMessage : NSObject {
NSOutputStream *outputStream;
NSInputStream *inputStream;
id <SKPSMTPMessageDelegate> delegate;
}
#property(nonatomic, assign) id <SKPSMTPMessageDelegate> delegate;
.m
#synthesize login, pass, relayHost, relayPorts, subject, fromEmail, toEmail, parts, requiresAuth, inputString, wantsSecure, \
delegate, connectTimer, connectTimeout, watchdogTimer, validateSSLChain;
Errors #2 & #3:
Passing address of non-local object to _autoreleasing parameter for
write-back
.h
#interface SKPSMTPMessage : NSObject {
NSOutputStream *outputStream;
NSInputStream *inputStream;
id <SKPSMTPMessageDelegate> delegate;
}
.m
[NSStream getStreamsToHostNamed:relayHost port:relayPort inputStream:&inputStream outputStream:&outputStream];
Any guidance will be greatly appreciated.
Thanks.

Answer 1

I have found right solution for this question.
The answer is: Dont bother yourself converting code manually.
You just need to add compiler flag -fno-objc-arc to imported classes

Answer 2

Error #1
Replase
#property(nonatomic, assign) id <SKPSMTPMessageDelegate> delegate;
To
#property(nonatomic, _unsafe_unretained) id <SKPSMTPMessageDelegate> delegate;
You can't use assign with ARC
Error #2,3
Try to not alloc and init outputStream and inputStream variables.
NSInputStream *inputStream;
NSOutputStream *outputStream;
[NSStream getStreamsToHostNamed:relayHost port:relayPort inputStream:&inputStream outputStream:&outputStream];
