In-Depth Information
Click on the disclosure triangle in the gutter. Xcode hides the selected code and replaces it with a placeholder
{…} graphic, as shown in Figure 9.2. To unhide the code, double-click the placeholder or click once on the dis-
closure triangle.
Code hiding selects paired curly brackets, so you can hide entire methods or specific code segments. If you hide
a complete method the signature remains. If you hide a smaller segment, such as the contents of an
if
state-
ment, the first line of the statement remains as a guide and the contents are hidden.
For convenience, you can also fold all of the code in a file. Select Editor⇒Code Folding and choose one of the
following options:
All:
Folds/unfolds everything between two matching delimeters.
Methods & functions:
Folds/unfolds methods and functions only.
Comment blocks:
Folds/unfolds comment blocks only.
You can use this feature to hide the large comment block that Apple always includes at the start of sample code.
FIGURE 9.2
