for example,
package testpkg
var AnInt int64
will be mapped to
@interface GoTestpkg: NSObject
+ (int64_t) AnInt;
+ (void) setAnInt:(int64_t)v;
@end

Given a Go package defining an interface,
package testpkg
type I interface {
Fn()
}
I is mapped to an objective-c protocol and a proxy interface
that implements the routing of method calls from Go.
@protocol GoTestpkgI
-(void)Fn;
@end
Users implement a class conforming the generated protocol. For example,
@interface MyI <GoTestpkgI> {
}
@end
@implementation MyI {
}
- (void)Fn { .... }
@end
Gobind will also create a proxy interface to handle Go objects
implementing the interface and passed to Objective-C, but that will
be hidden from users.
@interface GoTestpkgI : NSObject <GoTestpkgI> {
...
-(void)Fn;
@end
The gobind code to generate the objective-c binding is in a separate CL.

Also, fixes the memory allocation bug - misuse of mem_ensure that caused
to allocate 72 bytes of memory to carry 16 bytes of data for instance.

Before this change, func Hello() of mypkg package generated a function
GoMypkg_Hello to distinguish the prefix from the function name.
It seems the use of '_' is very rare in Objective-C though.
After this change, it generates GoMypkgHello.

With https://go-review.googlesource.com/10638, the reference counting
of Go objects can be simplified. Everytime a Go object is passed into
Objective-C side, a new proxy object with GoSeqRef is created.
Deallocation of a GoSeqRef decrements the reference counter of the
corresponding Go object.
Test the Go object is collected.
Note: It's possible to reduce the number of GoSeqRef
allocations by maintaining a map of weak references to the existing
GoSeqRef, but for now, we allocate a new GoSeqRef instance.

test.bash is a simple script that builds the c-shared library from
test_main.go, compiles SeqTest.m and the objective-c bindings of testpkg
(testpkg/objc_testpkg/GoTestpkg.*), and runs the output. Eventually this
will be replaced with coed that runs gomobile bind & xcodebuild.
The code under testpkg/go_testpkg and testpkg/objc_testpkg is the output
of gobind (now manually-generated). I am adding it to repo now in order
to get the testpkg/objc_tstpkg reviewed. Eventually, this will be
removed from the repo.
