Let’s start with some ui tips, there are 2 ways to make rounded views in iPhone. One is using layers which is inefficient way, second is using quartz in drawRect.

Using layers is really simple;


YourView *vw = [[YourView alloc] initWithFrame:CGRectMake(20, 20, 80, 80)];
vw.layer.cornerRadius = 16;
vw.layer.masksToBounds = YES;


simple. The right way is to handle in drawRect;

UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:self.bounds byRoundingCorners:UIRectCornerAllCorners cornerRadii:CGSizeMake(16.0, 16.0)]; //Add a bezier path
[path addClip]; // and clip


Both two will same view.

1 – Changing SIM card with new one ( currently 64Kb micro sim ) solved network loss and sim failure errors.
2 – Turning off a few location based services;

• Settings -> Location Services On -> Siri Off
• Settings -> Location Services -> System Services -> Cell Network Search & Compass Calibration is On and everything else Off.

The result is surprising, my iphone batter is 70 % with 1 day standby and 1 hour usage.

Update

You can still have 2 days standby with a few hours usage.

So far, your ideas helped me to improve the application to be more useful. Thank you for sharing your ideas with me. I’d be happy to see feedbacks.

The first app is developed to learn about platform and the application approval process which was a real pain. I’m hopping the next time, it will be easier to publish an app on app store.

I want to share some data about the app, despite it has been online for 6 days, the application is downloaded almost 1K, yes, almost 1000 times. Most of the downloads come from Turkey and followed by european countries like Denmark, Netherlands and those are followed by the US.

I want to thank everyone who downloaded the app.

Spending a few weeks (not full time) for learning and developing for Mac OS X is enough and fun. Learning Obj-c is not a big issue but it takes some time to get familiar with the libraries and frameworks. I made my choice to build an iPhone application as a start point and made a simple hello iphone world application and called it “Istanbul Guide”.

Application contains some popular places in Istanbul for the tourists and also, provides some basic information like text, photo and the current distance about locations. As I said app is not a big deal (some screens shown below), wait for the killer ones …
