Finishing Our First Cocoa App

摘要

In last month's column, I told you about my fabulous trip to Big Nerd Ranch for some down home Cocoa training with Aaron Hillegass and crew. We then started on our first in a series of Cocoa programs. We used Xcode to create a new project (named RandomApp), then used Interface Builder to edit the nib file and create the RandomApp user interface. Figure 1 shows the final configuration of the window we laid out in Interface Builder. The top button is used to seed the random number generator. Press the second button to generate a new random number. The new number is displayed in the text field below the two buttons. In Figure 1, the text field is selected and the blue, dashed lines show the window was being resized to leave the proper amount of space below the text field and to the right of the two buttons and the text field.
