[TIMOB-14498] iOS: Memory Leak issue for property set in tiapp.xml

Whenever i set any property in tiapp.xml, application reports a memory leak when analyzed using Instrument. Steps to reproduce: 1: Create a sample application and either cloud enable this or set any property like this in the tiapp.xml system 2: Build the application using titanium studio. 3: analyze the application using instrument for memory leaks. 4: after few seconds, instrument will show memory leaks. 5: check the source file for leak. 6: ApplicationDefault.m will be reported for leaks. 6: Code written there and responsible for leak is:

@implementation ApplicationDefaults
  
+ (NSMutableDictionary*) copyDefaults
{
    NSMutableDictionary * _property = [[NSMutableDictionary alloc] init];

    [_property setObject:[TiUtils stringValue:@"system"] forKey:@"ti.ui.defaultunit"];

    return _property;
}
@end

. Possible Solution: As per my understanding and finding, dictionary object should have been autoreleased while creating, so the above sample must have been written like:

@implementation ApplicationDefaults
  
+ (NSMutableDictionary*) copyDefaults
{
    NSMutableDictionary * _property = [[[NSMutableDictionary alloc] init] autorelease];

    [_property setObject:[TiUtils stringValue:@"system"] forKey:@"ti.ui.defaultunit"];

    return _property;
}
@end
