I noticed that there is much repeated work to do when creating Cocoa source code.

For example, if I set an instance for an object:

NSMutableArray *infoArray;  

I need add code:

@property (retain,nonatomic)    NSMutableArray *infoArray;  
@synthesize infoArray;  
in - (void)dealloc {

I also need add:

[infoArray release];

Is there any tool that can automate this, perhaps by automatically paste or copy the source code and add the repeated code at right place?
