Making Rounded UIView’ on iPhone

I have started developing (mainly) iPhone apps late 2009 and I feel like I have some experience on iOS platform that I can share. I won’t be doing tutorial serias but just some tips and tricks.

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.

I see my blog turns into iPhone Blog but I like this device 🙂 This weekend I took some photos from my new toy 🙂 new photos are taken in a cloudy day. I’ll try to take samples from different light conditions.

About iPhone 4S Sim Failure & Batter Usage

There are hundreds of posts & thousands of page views about iPhone 4S Batter Life at Apple Support Forums. A few days, I’ve faced same problems a few days like I had no sim and sim failure errors, network losses and a few hours with full charge ! It seems problem is related directly with Apple but still there are solutions, at least two things worked for me;

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;

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


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