Using Objective-C on my iPhone, is there a built-in method for NSString that finds a string appearing BETWEEN 2 other stings? Search "my dog is my cat's best friend"... and return everything between "dog" and "best". Or will I have to write my own? Any good ideas on where to start? Thanks. ...

A UIView may only be the delegate for one layer and that is the layer the UIView already has from the get go. Since I also didn't want to sub...

I have been asked by many of my family and friends if I could develop applications on the iPhone or iPod touch. The answer I always gave was "sure, if I could get everything I needed." I have discussed this with many friends and we believe that if we can crank out cheap-o fun games and get a million people to buy them for a buck, and d...

Consider the following example: The grey area is an image in the PNG or JPG Format, now I want to select the red 80x80 px area from it. The red area should be displayed, the rest not.

I'm interested in showing a blue dot in my table cells just like the Mail application does for unread emails. My understanding is there is no easy way of doing this except to create the images myself and set the image properties of my cells. So now I have created two square images, one with a blue dot and another blank image with the sa...
When a button is pushed in one of my app's table view cells, I need to push a certain view controller onto the navigation stack.

But that would be awfully heavyweight, especially since selections in a tab bar in the app ...
