Hey, I am making a custom table cell right now but my custom cell is just white cell with some buttons and labels in background color which looks not that great. Is there a way to render the background color so that the cell has some vertical gradient effect? For example, on top of the cell it looks white and as it gets closer to center ...
Just starting to poke around iPhone development. I am trying to add an external project/library to mine (specifically the ASIHTTPRequest, http://allseeing-i.com/ASIHTTPRequest/). I am at a bit of a loss as to how I go about actually adding this dependency to my project. I come from a Visual Studio/C# world, and in Visual Studio I kn...
I have a uipickerview in an iphone app. If you select one of the components in the view with just a tap (instead of a swipe) the component slowly ticks into the selection position. It behaves the same in the simulator, the iphone and an ipad so it seems like this is a specific behavior. Does anyone know if there's a setting that will mak...
Per http://developer.apple.com/iphone/library/documentation/Cocoa/Reference/Foundation/Classes/NSDateFormatter_Class/Reference/Reference.html The init method of NSDateFormatter is "Available in iPhone OS 2.0 through iPhone OS 3.2", and therefore not in 4.0. Now, it certainly works, but this seems odd. Is this is a mistake or is there...

Here is my code in the drawRect char *string = "TEST"; CGContextRef context = UIGraphicsGetCurrentContext(); CGContextBeginPath(cont...
I want my text box to blink (like the old LCD clocks) and right now I'm calling a myriad of NSTimers and selectors that wait, change the alpha, wait, then change it back. Even with this it looks really bad, and I'm thinking I have to put an NSTimer to gradually change the alpha, but from what I hear they are not meant for things of that ...
I've got an UIImageView as a background image for my application, which, like a helicopter in distress, autorotates. The problem is when the orientation autorotates my image gets shifted all over the place and I don't like it. Since it's a simple texture I figure the user would prefer to have it stay in its place, and not autorotate. Wha...

Hi everyone, I updated my 3G iphone to 0S4 and the game I wrote for it is now very slow. I.e it starts off well, but then the game slows down after a while and it becomes uplayable. I ran instruments but instruments cannot run and becomes very slow so I tried running it against the simulator and noticed the same thing. Also my ram neve...
I've been at this for awhile, it seems that there's many ways to go about this in quartz 2d: 1) Draw text using core graphics methods... CGContextSelectFont CGContextSetRGBFillColor CGContextShowTextAtPoint and on and on, which is horribly low level. 2) using NSString drawAtPoint (so far the method I like) NSString* text = @"Hello"...

I'm using an nstimer to update the position of the images and calling [self setNeedsDisplay] to update the drawing. In the simulator, it looks very good, however, on the device, it i...
