| 1 Going Mobile with iOS |
|
|
So, you want to build an iOS app... |
|
|
2 | (1) |
|
...'cause everyone wants one! |
|
|
3 | (1) |
|
Apps live in an iTunes universe |
|
|
4 | (1) |
|
|
|
5 | (1) |
|
It all starts with the iPhone SDK |
|
|
6 | (1) |
|
|
|
7 | (1) |
|
Xcode includes app templates to help you get started |
|
|
8 | (1) |
|
Xcodc is a full-featured IDE |
|
|
9 | (1) |
|
Xcode is the hub of your iOS project |
|
|
10 | (4) |
|
Build your interface within Xcode |
|
|
14 | (1) |
|
Add the button to your view |
|
|
15 | (2) |
|
The iOS simulator lets you test your app on your Mac |
|
|
17 | (1) |
|
|
|
18 | (1) |
|
|
|
19 | (4) |
|
You're using the Model View Corn roller pattern |
|
|
23 | (1) |
|
iDecidc is actually a little simpler |
|
|
24 | (2) |
|
|
|
26 | (1) |
|
Use the GUI editor to connect UI controls to code |
|
|
27 | (1) |
|
A component can trigger certain events |
|
|
28 | (1) |
|
Connect your events to methods |
|
|
29 | (2) |
|
You've built your first iPhone app! |

| 2 Hello, Renee! |
|
|
First we need to figure out what Mike (really) wants |
|
|
43 | (5) |
|
App design rules—the iOS HIG |
|
|
48 | (3) |
|
HIG guidelines for pickers and buttons |
|
|
51 | (1) |
|
Create a new View-based project for InstaEmail |
|
|
52 | (2) |
|
|
|
54 | (6) |
|
|
|
60 | (1) |
|
Use pickers when you want controlled input |
|
|
61 | (1) |
|
Pickers get their data from a datasource... |
|
|
62 | (1) |
|
|
|
63 | (5) |
|
First, declare that the controller conforms to both protocols |
|
|
68 | (2) |
|
The datasource protocol has two required methods |
|
|
70 | (1) |
|
Connect the datasource just like actions and outlets |
|
|
71 | (1) |
|
There's just one method for the delegate protocol |
|
|
72 | (5) |
|
Actions, outlets, and events |
|
|
77 | (4) |
|
Connect the event to the action |
|
|
81 | (4) |
|
Next, synthesize the property.. |
|
|
85 | (1) |
|
Connect the picker to our outlet |
|
|
86 | (1) |
|
Use your picker reference to pull the selected values |
|
|
87 | (9) |
|
|
|
96 | (4) |
| 3 Email needs variety |
|
|
|
|
100 | (1) |
|
Make room for custom input |
|
|
101 | (2) |
|
Header files describe the interface to your class |
|
|
103 | (6) |
|
Auto-generated accessory also handle memory management |
|
|
109 | (2) |
|
To keep your memory straight, you need to remember just two things |
|
|
111 | (10) |
|
But when Mike's finished typing... |
|
|
121 | (2) |
|
Customize your UITextField |
|
|
123 | (1) |
|
Components that use the keyboard ask it to appear... |
|
|
124 | (1) |
|
Ask the UITextField to give up focus |
|
|
125 | (2) |
|
Messages in Objective-C use named arguments |
|
|
127 | (1) |
|
Use message passing to tell our View Controller when the Done button is pressed |
|
|
128 | (4) |
|
|
|
132 | (7) |
|
|
|
139 | (6) |
| 4 A table with a view |
|
|
So, how do these views fit together? |
|
|
145 | (1) |
|
The navigation template pulls multiple views together |
|
|
146 | (1) |
|
The table view is built in |
|
|
147 | (5) |
|
A table is a collection of cells |
|
|
152 | (8) |
|
Just a few more drinks... |
|
|
160 | (2) |
|
Plists are an easy way to save and load data |
|
|
162 | (3) |
|
Arrays (and more) have built-in support for plists |
|
|
165 | (3) |
|
Use a detail view to drill down into data |
|
|
168 | (1) |
|
A closer look at the detail view |
|
|
169 | (10) |
|
Use the Navigation Controller to switch between views |
|
|
179 | (1) |
|
Navigation Controllers maintain a stack of View Controllers |
|
|
180 | (4) |
|
Dictionaries store information as key-value pairs |
|
|
184 | (3) |
|
Debugging—the dark side of iOS development |
|
|
187 | (1) |
|
First stop on your debugging adventure: the console |
|
|
188 | (1) |
|
Interact with your application while it's running |
|
|
189 | (1) |
|
Xcode supports you after your app breaks, too |
|
|
190 | (1) |
|
The Xcode debugger shows you the state of your application |
|
|
191 | (4) |
|
|
|
195 | (3) |
| 5 Refining your app |
|
|
It all started with Sam... |
|
|
198 | (2) |
|
Use the debugger to investigate the crash |
|
|
200 | (3) |
|
Update your code to handle a plist of dictionaries |
|
|
203 | (3) |
|
The Detail View needs data |
|
|
206 | (1) |
|
|
|
207 | (6) |
|
We have a usability problem |
|
|
213 | (2) |
|
Use a disclosure button to show there are more details available |
|
|
215 | (3) |
|
|
|
218 | (5) |
|
Use Navigation Controller buttons to add drinks |
|
|
223 | (4) |
|
The button should create a new view |
|
|
227 | (1) |
|
We need a view...but not necessarily a new view |
|
|
228 | (1) |
|
The View Controller defines the behavior for the view |
|
|
229 | (1) |
|
A nib file contains the UI components and connections... |
|
|
230 | (1) |
|
You can subclass and extend view controllers like any other class |
|
|
231 | (5) |
|
Modal views focus the user on the task at hand... |
|
|
236 | (1) |
|
Any view can present a modal view |
|
|
237 | (5) |
|
Our modal view doesn't have a navigation bar |
|
|
242 | (2) |
|
Create the Save and Cancel buttons |
|
|
244 | (1) |
|
Write the Save and Cancel actions |
|
|
245 | (4) |
|
|
|
249 | (3) |
| 6 Everyone's an editor... |
|
|
Sam is ready to add a Red-Headed School Girl... |
|
|
252 | (1) |
|
.,.but the keyboard is in the way |
|
|
253 | (2) |
|
Wrap your content in a scroll view |
|
|
255 | (2) |
|
The scroll view is the same size as the screen |
|
|
257 | (3) |
|
The keyboard changes the visible area |
|
|
260 | (2) |
|
iOS notifies you about the keyboard |
|
|
262 | (1) |
|
Register with the default notification center for events |
|
|
263 | (6) |
|
Keyboard events tell you the keyboard state and size |
|
|
269 | (19) |
|
The table view doesn't know its data has changed |
|
|
288 | (4) |
|
The array is out of order, too |
|
|
292 | (8) |
|
Table views have built-in support for editing and deleting |

Don't forget the tableview |

Build the fugitive list view |
|
|
382 | (2) |
|
Next up: the Captured view |
|
|
384 | (8) |
|
A view's contents arc actually subviews |

Core Data lets you focus on your app |
|
|
396 | (1) |
|
Core Data needs to know what to load |
|

|
Core Data describes entities with a Managed Object Model |

Bob's database is a resource |
|
|

|
The template sets things up for a SQLite DB |
|
|
419 | (2) |
|
|
|
421 | (1) |
|
The iPhone's application structure defines where you can read and write |
|
|

|
Copy the database to the Documents directory |

| 9 Things are changing |
|
|
|
|
446 | (3) |
|
Everything stems from our object model |
|
|
449 | (3) |
|
The data hasn't been updated |
|
|
452 | (1) |
|
Data migration is a common problem |
|
|
453 | (1) |
|
Migrate the old data into the new model |
|
|
454 | (1) |
|
Xcode makes it easy to version your data model |
|
|
455 | (2) |
|
Core Data can "lightly" migrate data |
|

|
|

|
Use predicates for filtering data |
|
|
478 | (1) |
|
We need to set a predicate on our NSFetchRequest |
|
|
479 | (7) |
|
Core Data controller classes provide efficient results handling |
|
|
