The Tools Figure 1. The relationship between Xcode, GDB, Interface Builder, Instruments, and iPhone Simulator. These are the main tools for developing NATIVE iPhone applications. Dashcode is used for developing WEB applications. Xcode Figure 2. Xcode with Metronome project open. This is the central tool in the development toolset for iPhone, iPod Touch, and Mac OS X applications. All the project related files can be seen in the left navigator. GDB (GNU Debugger) Figure 3. The debugging functionality from Xcode, via a GUI window. This window is probably most helpful during most of the debugging. You can see the callstack, variable information, and source in the same window. Figure 4. The debugging functionality from the GDB console. This window provides all the raw power of GDB. A large set of commands can be used to find out information about variables/objects, breakpoints, call stack, etc. Interface Builder Figure 5. The Interface Builder is shown with the Document Window, the View, the Attribute Inspector, and the Library (or the Toolbox). Here the user interface is a Table View, a commonly used view. Instruments Figure 6. Looking at the Object allocation and Leaks from Instruments. Dashcode Figure 7. Developing web applications for iPhone using Dashcode. You can see the standard web file extensions (.html, .css, and .js for JavaScript) iPhone Simulator Figure 8. A utility web application with Dashcode - shown in the iPhone Simulator. This does not require the iPhone SDK. Figure 9. An application built from Xcode running inside iPhone Simulator. This application is native to iPhone OS and is built with iPhone SDK. This is NOT run inside the Safari web browser (though Internet functionality can be added to native iPhone applications)
