It’s surprising because this feature is available since the iOS version 3.2 but I’ve just figured it out today, in one hand this is just another example of how big and complete the SDK is but on the other hand it also makes almost impossible to know about all of its features.

Indeed it’s pretty simple, you just have to:

- add font file to project, I’m not sure if it has to be a .tff or an .otf, you’ll have to try it by yourself

- open info.plist and add a UIAppFonts key, which is an array, so you can add as many fonts as you need. Remember you just have to add the font filename for each one, i.e. newfont.ttf

- Now you’re ready to use your font inside the source just like any other font, i.e: [UIFont fontWithName:@"newfont" size:12];

I had this strange issue for a long time in one of ours projects, it’s a very strange issue as it only happens in one specific scenario. I have a UIWebView that loads an html content from a local file, which has to be loaded without any scaling to fit, it just has to be displayed filling the current width/height screen size. If the webview is loaded in portrait and then rotated to landscape, and again to portrait everything works fine, the view is resized and the content repositioned as it has to.
The issue only happens when it’s loaded in landscape mode and then rotated to portrait, in that case the content is not resized as it should be, it remains 1024px wide when it should stay at the original 768px, and a couple of scroll appears.

The only way to fix it I found was to insert thist html code:
<meta name='viewport' content='width=device-width; initial-scale=1.0; maximum-scale=1.0;'>


If you need more info you can take a look at the original threat from where I’ve got the trick.

We hope to be successful and contribute a bit to promote La Marató.

This app is a pocket catalogues of all the products that can be found in each Salvador Bachiller(SB) store and a SB’s news and promotions reader. SB’s team will update the content weekly to keep you informed about all its new products. Now the users will can buy SB’s products by his online store using iPad or iPhone.

Now the user can use Google maps functionalities to search his closest store.

Finally the app offers the possibility to search low cost flies, by Trabber services. And get information about the airlines and his luggage conditions.

This app is a pocket catalogues of all the products that can be found in each Pull&Bear store, organized by sections which is very useful for all customers, but one of the most important features of the application is the update frequency: Uterqüe’s team will update the content weekly to keep you informed about all its new products.

Now the user can use a Augmented Reality or Google maps functionalities to search his closest store.

I would like to take this post to talk about mobile marketing posibilities, there is a lot of companies around the world using mobile marketing solutions to promote their products. iPhone and large set of latest mobile devices has the multimedia capabilities to provide a very easy, clear and useful channel of communication between companies and it’s potential customers.

The fact of Uterque releasing a set of applications available in most important plattforms(iPhone, Android, Nokia, Blackberry,…) it’s just another example of how useful can be for the companies to keep his customers updated with it’s latest products through a maketing mobile application.

Download this application to be informed of updates season. You can also view the catalog, know at our premiere proposals fashion, with the most suggestive looks for every time and Tintoretto locate a retailer near you.

Now the user can use Google Maps functionalities to situate the tintoretto’s store.

This application allows to read about the next party on Millennium Cosmic club and share this using Facebook connect and email.

It also gives the possibility to convert the user into a Millennium’s DJ through a little game. Where by selecting a sound and shake the iPhone, users can create a session to their friends.

By the publication of this application, Millennium enters to the exclusive group of clubs that have released their iPhone application.

The exact radius for the icon rounded corners is:

• iPhone OS 3.x(57×57) is 9 pixels
• iPhone OS 4.0(114×114) I guess it’s 18 pixels but I’m not sure of that

The exact radius for the Artwork(512×512) is 80 pixels.

1. Make the MyViewController a UIScrollViewDelegate. Do this by adding in the @interface declaration in the .h file.
2. Create a UIImageView instance variable in the @interface of MyViewController. We will need this to specify it to the Delegate which object is to be zoomed. Add the @property and @synthesize for this image in relevant places. I used scroll2ImageView as the name of the instance.
3. In the viewDidLoad Method in myViewController.m class replace the code for setting up scrollView2 with this code.

[scrollView2 setBackgroundColor:[UIColor blackColor]];
[scrollView2 setCanCancelContentTouches:NO];
scrollView2.clipsToBounds = YES; // default is NO, we want to restrict drawing within our scrollview
scrollView2.indicatorStyle = UIScrollViewIndicatorStyleWhite;
scroll2ImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image0.jpg"]];
[scrollView2 addSubview:scroll2ImageView];
[scrollView2 setContentSize:CGSizeMake(scroll2ImageView.frame.size.width, scroll2ImageView.frame.size.height)];
scrollView2.minimumZoomScale = 1;
scrollView2.maximumZoomScale = 3;
scrollView2.delegate = self;
[scrollView2 setScrollEnabled:YES];


We made three changes here. First we replaced the local instance of imageView with the class instance scroll2ImageView. We will need this in the next step. Second we added min/max zoom scale for the image. Third we assigned the scrollView2 delegate to self.

4. Last thing we need to do is tell the delegate wat all to zoom when it detects a zoom in/out pinch. We add the following method for this.

-(UIView *) viewForZoomingInScrollView:(UIScrollView *)scrollView {
return scroll2ImageView;
}

I didn’t knew the answer at this moment but once I got to the office I decided to look for it. After a few minutes googling I found the answer: it’s possible, and here is the source code to do it.

NSArray *topLevelObjs = nil;
topLevelObjs = [[NSBundle mainBundle] loadNibNamed:nibNameOrNil owner:self options:nil];

if (topLevelObjs == nil)
   NSLog(@”Error! Could not load nib file.\n”);


[myMailComposerVC setTitle:@"My title"]

but if you do that you don’t get anything, you still get the “NEW MESSAGE” text.
The way I found to access it is the following. Maybe there is another/better don’t know but this one definitely works:

[[[[myMailComposerVC navigationBar] items] objectAtIndex:0] setTitle:@”My title”];

Hope it helps someone as much as it helped me.

You might wonder if that is because there is no easy way to build an application with both HD graphical assets and nonHD graphical assests that looks great on all iPhone OS versions. But that’s not true. Recently I found out a very esy way to do that:

UIKit supports the automatic loading of high-resolution variants (@2x) of your images.

The “only” thing you have to do is generate HD graphical images of each existing image in your current project and name it the same but with an @2x in the end. i.e:

previous image name: logo.png

HD image name: logo@2x.png

once you have all the images just import to your existing project and compile it again using the same iPhone OS version you used to compile the nonHD version of the application, and submit it to the store.

Et voilà! The iOS 4 will handle it automatically to display your new HD images.

There are no big changes on the applications, the most important one is we removed the in app purchase service of the application, but we added we’ve added adMob advertisements. So the application is completely free right now

In this version you’ll also find:

• Some minor performance issues fixed.
• Updating bug when launching the application fixed.
