Have got an NSString *str = @"12345.6789" and want to find out if there is that "." character inside of it. I'm afraid that there are ugly char-encoding issues when I would just try to match an @"." against this? How would you do it to make sure it always finds a match if there is one? I just need to know that there is a dot in ther...
Basically I have a hierarchy of locations: country, state/prov, city. I want to present an "Add Location" modal table using a delegate. I realize the best way to do this is to present my top level elements in a TableView, and if they are selected, I want to go down to the 'next' level. Any of the locations however, on any level should...

Hey guys, I'm having a problem with doing a sendSynchronousRequest failing. It only fails after I try to get the current geolocation and the user hits "Don't Allow". And it only happens under 3.1.2. (As far as I can tell. It works fine in 3.0.1.) Here's what I do: I set up a very basic test app, that has almost nothing in it. In appli...

I recently purchased a Magic Mouse. It is fantastic and full of potential. Unfortunately, it is seriously hindered by the software support. I want to fix that. I have done quite a lot of research and these are my findings regarding the event chain thus far: The Magic Mouse sends full multitouch events to the system. Multitouch events a...

I've got the background set as a UIImageView and if I set it to an Image in Interface Builder it works, but I can't change the background programatically. Here is the code I'm using (I based it off a tu...

The goal is to generate an NSString chars in length and assign each string to an array. I'm getting stuck on what I need to do with my algorithm to get the correct result. Here's the sample. The result I get is the same randomly generated string added to my array 26 times instead of 26 DIFFERENT strings added. I've thought about de...
Most of the documentation that details how to get started with JNI described how to build a new JNI application using X-Code. Can anyone link me to a description of how to use JNI to interface with Objective-C in an existing application. ...
Hello, I have been developing with objective C and the Cocoa framework for quite some time now. However it is still not absolutely clear to me, when am I supposed to set object references to nil. I know it is recommended to do so right before releasing an object that has a delegate and you should also do so in the viewDidUnload method f...
