468 CHAPTER 25 MAC <strong>OS</strong> X DEVELOPMENT: THE TOOLS Navigation Though they’re easy to miss, there are several navigation aids along the top of any editor view (shown in Figure 25-16). These make it easy to move between different areas of a file, or even between files. Figure 25-16. Navigation controls on the top of Xcode’s editor On the left side there are back and forward buttons, a history menu, which lets you jump between recently edited files, and a function menu. The function menu lists any function, method, or class declarations, as well as defines, typedefs, and pragmas. Selecting an item from the function menu jumps to that item on the page. You can add navigation aids to your page, which will then show up in the function menu. Perhaps the most common is the mark pragma: #pragma mark This is some text. This will cause any text after mark to show up in the navigation menu, like so: This is some text. As with anything else, you can jump to the mark by selecting it. If you group your methods by functionality, marks are a great way to add subheadings to set off the sections. You can also use the mark pragma to add separators to the menu. #pragma mark - You can add comments to the function menu by beginning them with certain special prefixes. These prefixes and some examples of their use are listed in Table 25-1. Table 25-1. Xcode’s Special Comment Prefixes Prefix Example Result //???: //???: Is this really necessary? ???: Is this really necessary? //!!!: //!!!: This crashes every 3rd time !!!: This crashes every 3rd time //TODO: //TODO: Implement the edge case TODO: Implement the edge case //FIXME: //FIXME: The image no longer shows FIXME: The image no longer shows The editor’s upper right has several small buttons. These reveal menus for jumping to bookmarks, breakpoints, includes, and other files that define the current class, including superclasses, subclasses, and categories. There is also a button to jump between the current class’s header and implementation files. TIP You can jump between a class’s header and implementation files by typing Option+Cmd+up arrow. In the upper-right corner, there is a small lock icon. Clicking this icon will lock (or unlock) the current file, preventing accidental edits. Below the lock is a button that will horizontally split the editor into two independent views of the same file. Halves can be further split, and the split can be adjusted by dragging the divider. When an editor is split, a button will appear for rejoining the two halves.
Errors and Warnings Traditional programming separates writing code from building programs. Although Xcode has always done both, it continued to require leaving the editor to see the results of a build, and then switching back and forth between modes to handle any errors or warnings from the build system. Xcode 3 finally merges these two modes with inline error and warning pop-up bubbles, as shown in Figure 25-17. Figure 25-17. Xcode’s new inline error and warning bubbles You can hide or reveal the bubbles by clicking their icons in the gutter. Warning and error bubbles can also be toggled en masse via the View menu. You can also use the keyboard shortcut Cmd+= to move forward through the bubbles and Cmd++ (that’s Cmd plus the + key) to move backward. I cannot overstate what a tremendous improvement this is. The time saved by not having to switch contexts is enormous, especially for multifile edits. NOTE Using = to move forward and + to move backward seems counterintuitive. Shouldn’t + move forward and - move backward? However, given the standard keyboard layout, + is actually Shift+=, so these shortcuts make good sense in practice, even if they seem weird in writing. Debugging CHAPTER 25 MAC <strong>OS</strong> X DEVELOPMENT: THE TOOLS 469 No matter how good a programmer you are, you’re going to have bugs. Whether it’s a fullfledged crasher or just an unexpected result, getting to the bottom of things gets exponentially harder as a program grows in size and complexity. When reading the code and logging aren’t enough, it’s time to pull out the big guns. Xcode not only includes the GNU debugger, GDB, but integrates it into the interface in a way that’s much easier than traditional command-line debugging.
