Designing Apps for Multiple Screen Sizes in iOS


The iOS is considered to be the most expensive mobile operating system in the world. The reason was that apple created iOS only for their devices, which are very expensive. Apple mobile devices started evolving with the introduction of the first smartphone (iPhone) back in 2007. There after apple started innovating new line of mobile devices and they were created according to the user needs in different sizes.

Apple iPhones were their first mobile devices. In year 2010, apple introduced a new product called iPad. Apples started making billions with these products and developers started making mobile applications that fits the user’s needs. Developers had to make apps that fit the screen size of these different devices. The iPhone’s had different screen sizes while iPads were completely different. Below are the iPhone devices with corresponding resolutions.

Pixels are the smallest physical element that we can control on a digital display. The more pixels can be fitted into a specific screen size, the higher the PPI and the clearer the rendered content becomes. Points are a resolution-independent measurement. Depending on the screens pixel density, a point can contain multiple.

When you are designing for various display types, you should think in points, but design in pixels. This means you will still need to export all your assets in 3 different resolutions, no matter in which resolution you are designing your app.

People are currently using iPhone 4S to the latest iPhone model iPhone 6 plus. Apps are to be created for these models to display correctly according to the correct resolutions. When designing a mobile application for apple devices there are few things to consider.

    Things to Consder

  1. Are things visible at different screen sizes?

Just like in responsive website designing, you need to check whether the content that you put on a specific app is visible correctly. After determining the size, the very next step will be to correctly display it to the user.

  1. Can fingers touch these things effectively? Are they too small?

When you make the components bigger or smaller to match a specific resolution, you need to determine whether the user can touch these components correctly. If you made changes to a certain button make sure it’s clickable by the user. If that button was placed in iPhone 4, you will probably need to change it to look good in iPhone 6 plus with a screen size for 5.5 inches. To support high-resolution graphics on devices with retina displays, create two versions of the image: a standard size image, and a double-sized image with added to the name.

  1. Is there too much white-space in larger screen sizes

Having too much white space in a design is not acceptable at all. That doesn’t mean that you have to stuff your background with lot of details. Add what is needed and as mentioned earlier create at least 2 versions from each. You don’t want to custom design for multiple form factors as it makes the app complex. Try to reduce the complexity and avoid using incompatible components for each.

How to design properly

When designing iPhone apps it is recommended to make prototypes prior to the final version of the application. By creating iPhone mockups you can easily create a working prototype. It is important to design mockups for various sizes and functionality. By doing so you can make sure that your design will fit any screen.

Do wireframes with actual images, put them on the phones and see if you can work with them. Then you’ll know how each screen works and how it appeals to the user. Change accordingly and make a final version that is compatible with all screen sizes.

When implementing, use responsive components where possible or use different layouts for different sizes. Using apple predefined font packs can reduce the amount of risk your text not being displayed. You can check the colors with the retina version of the MacBook as they pretty much share the same screen panels.

The more specific and detailed you create your app, the more likely users are to get it right. Creating something like this seems like a momentous job, but it reduces significantly the amount of time you’ll need going over your designs with a developer. Plus you’re much less likely to be annoyed by incorrectly implemented UI. Make sure that you always think as a designer than a developer when creating iPhone apps. Always follow your iPhone mockup software to get an idea about your apps right.

Trip Nuwara Eliya While Tours to Sri Lanka

I decided to go to Nuwara Eliya this time in my Sri Lanka Tours . Nuwara Eliya, otherwise known as “Little England,” is a quaint town located in Sri Lanka’s beautifully lush hill country. During the British Colonial Period, Nuwara Eliya was a favorite holiday retreat for the crème de Ia crème of British society on the island. They turned this town, with its ideal cool temperature and rich foliage, into a beautiful little town strongly reminiscent of England, from the architecture of the houses to the flowers that still peep out of every corner. To this day, Sri Lanka’s “Little England” remains almost completely untouched and you feel like you’ve skipped continents as you enter its city limits.

Nuwara Eliya’s tradition has remained unchanged as it is still known to be a retreat for the island’s elite. During its ‘season’ in April, the little town comes alive as Sri Lanka’s high society flocks there for the horse and motor races, grand dances and exclusive golf tournaments. Visiting one of the many tea factories perched high on the hills surrounding Nuwara Eliya is definitely a must. It is here that the best of Sri Lanka’s teas – the fragrant and delicately flavored “high grown” – flourish.

Nuwara Eliya’s Galway Bird Sanctuary is a 27 acre park where you can catch a glimpse of a great variety of rare and tropical birds, an unbeatable spot for nature-lovers. The Hakgala Botanical Gardens, Victoria Gardens and Horton Plains are also great places to visit if you want to take in Nuwara Eliya’s unique landscape and carefully maintained flower gardens. “World’s End” is another popular site in Nuwara Eliya . It is a terrifying precipice which drops vertically for about 1,000 feet (328 meters) and falls away almost as steeply for another 4,000 feet (1,312 meters). If you are already in your Sri Lanka holidays I recommend these places for you.

Wonderful Sri Lanka Tours to Hikkaduwa

This is a place you must visit if you are in down south and on a Sri Lanka Holidays . Located 98 km south of Colombo, Hikkaduwa is one of the most popular beach resorts of Sri Lanka. Sri Lanka’s only marine sanctuary is located here. It is an ideal place for nature lovers with its abundant corals and tropical fishes. Hikkaduwa has something to offer to everyone-coral for snorkellers, waves for surfers and white pristine beaches for those who want to relax and enjoy Sun and sand. Coral Sanctuary The large shallow body of water is enclosed by a reef, decorated with layers of multi colored corals it is home to countless number of colorful coral fish, lobsters, large turtles and microscopic marine creatures. Approximately 200 m away from the beach there is a collection of tiny islets that are surrounded by beautiful coral formations. The four different shipwrecks waiting to be explored are a treat for the diving enthusiasts. The corals are located only 4 m below water, therefore can be easily accessed by novice divers; however if diving is too adventurous visitors could take a trip on a glass bottomed boat to enjoy the beauty of the coral sanctuary. This is a wonderful experience you can have while on your Sri Lanka Tours .

Precious Stone Found in Sri Lanka Holidays

 In the beginning of my Sri Lanka Holidays , have I told you about the sapphires from down south of Sri Lanka? I guess not. In Sri Lanka down south area is very beautiful consisted with exotic beaches and the area is infested with tourists. There are some minor mining operations going on near Matara. When I was in Sri Lanka I couldn’t visit those sites. But I’m pretty sure one of my blue sapphire rings are from Matara region. The reason for this is that Sapphires from a region close to Matara are typically of a deep dark blue color almost black and are glossy textured. These have earned the name ‘Matara Sapphire’. It is well known that certain sapphires when subject to heat lose their color. In still others heat could spread out the color within the stone. Great skill and care is necessary in conducting such heating operations. Not many mining operations are done in this area. People in this area sustains from small house businesses and fishing.

There are two major sapphire dealers in Matara area. They are Mr. Gunadasa & Mr. Ariyapala. I never got to meet either one of them. But I’m so glad that I bought a sapphire ring consisted with a blue sapphire from Matara. I bought it from my visit to Beruwala sapphire market with tisa. Beruwala is near to down south area of Sri Lanka. I’m very a happy about the sapphires I bought all together because they are the most precious stones I found in my Sri Lanka Holidays .

Moving Down to Matara

Matara is a city in the down south where lot of important places to visit if you are in a Sri Lanka Tour . First of all since my last journey I didn’t plan on going anywhere but the beach. So I decided to go out again to have fun In the coastal area. This Time I decided to visit Matara the city of my desire. I personally liked Matara because it has nice beaches and surroundings. I like the Polhena beach because it is the best place to relax and have a nice swimming in the ocean.

Sea foods in the Matara area are amazing. Especially the fishes are delicious and I would say the best plate I ever had was Talapath fish. It was an amazing dish I still remember the taste. The cuttlefish fish was even better with rice and some other curries specially made in Matara Area. The most amazing desert I ever had in Matara was the Curd. I loved eating curd, because it was really tasty and fresh. I packed few for my journey ahead as well. However I decided to have all my meals in the hotel as eating from some of the boutiques can be dangerous. I have heard stories of foreigners who got food poisoning in India before coming to Sri Lanka thru some of my friends.

The cultural values in Matara area were amazing. I got to watch some traditional dancing and Perehara event in Matara. It was an amazing experience for me as I have never seen such stuff in my own country. Perahara was the most interesting thing I saw in Matara where lots of traditional items were presented on the road. There were elephants carrying holy crest and some fire dancers were playing on the road as well. I was staring at acrobatic dancers as well they were amazing. I went back to my hotel planning to more in to the down south further to a wonderful Sri Lanka holidays.      

Galle Fort

It was another important day in my Sri Lanka Holidays , to save time and money I decided to take the highway to down south. I really did not know what I was missing. Later on I got to know that there are many places to visit ion the coastal belt in Sri Lanka little areas along the way. The normal road is called as Galle Road, because it is the direct way to the Galle. I did not want to go by the Galle road because of all the traffic and other concerns. Anyway after a one hour of hectic long drive we came to the entrance of highway is Kottawa. After entering the highway I was sightseeing around until we reached Galle in 45 minutes. That wasn’t so bad.

After entering the city we experienced a little bit of traffic. Then I straightly went to the hotel I pre-booked in to. It’s a very beautiful place in Galle Fort called Mango Hut. I was so excited to visit there as I have seen the pictures in the internet prior to coming here. After unloading and unpacking I decided to have lunch. Again I was fortunate enough to have a wonderful spicy Sri Lankan meal. It was non-other than favorite steamed rice and some delicious Sri Lanka dishes. After having lunch I felt very sleepy. It was something new to me after coming to Sri Lanka. It was the weather I guess.

I woke up at tea time here in Sri Lanka and started walking towards the Galle fort. It was a very beautiful area with a wonderful beach. This area was considered as one of the historical places in Sri Lanka. When Sri Lanka was under British domination this was an important point in Sri Lanka. I walked through the stone wall in the fort. It was almost the sunset and the sight was amazing. I stared at the beach for the while when some street merchandisers approached me. I decided to go back to my room in Mango Hut ending another day in my Sri Lanka Holidays .
