You are not storing the pointer to the allocated object. Think you've ment:

_sharedUploaderThread = [[self alloc] init];

You never set _sharedUploaderThread equal to the [[self alloc] init]. Thereby leaking it.

You are not assigning the value to _sharedUploaderThread. Do 

_sharedUploaderThread = [[self alloc] init];

Since you were not assigning the value, you were leaking.
