Cocoa Touch is an awesome API, it contains a large set o frameworks that can be used to create fantastic applications for iPhone, iPod Touch and iPad, but if we compare Cocoa Touch with Cocoa API for MacOSX we won’t find some cool features like masking on input controls.


Returning a textual representation of a object in Objective-C

Today I discovered how objetive-c allows the programmer to generate a textual representation of a object, you can do it by implementing a description method of NSObject protocol.

Please consider the following class interface:


@interface Contact : NSObject {
    NSString *name;
    NSString *address;

@property (nonatomic, retain) NSString *name;
@property (nonatomic, retain) NSString *address;

#changing to directory where the sources can be found
cd ~/projects/helloworld

make clean

#build application binaries

#creating the application package to deploy on device (or emulator)
sdk –p

You can run the application by clicking on runqpe icon on desktop.

I personally would like to see Qtopia platform as real option of application platform for Nokia devices, Qtopia has a lot of features that makes the application development much more easy than Symbian platform.


RSocket bug in S60 SDK third edition

Posted by – June 14, 2008

I’m just wondering if this bug will have a solution in future versions of Nokia S60 SDK, this is a very bad bug where the symbian application can’t connect more than 400 times without reboot. How can I create a mobile applications for this platform if I know this will stop because of platform bug? What about stop the development of applications to this platform?

The worst part is, Nokia doesn’t care about bug severity and the only thing that Nokia can say is “this bug will be fixed in future releases of S60 SDK”, terrible!

Nokia really cares with your costumers and how much he can help your costumers? The answer is simple: NO!!!!
