Duration: 00:31:45  File Size: 92 MB

Lesson 10

Lesson 4 (Advanced): Threads

Lesson 4, “Threads,” emphasizes the importance of understanding threads. Viewers are introduced to Grand Central Dispatch, the core of the Objective-C threading model. The lesson covers how to use the low-level Grand Central Dispatch interface (C API) to submit jobs to the dispatch queue system. Viewers learn how to use the Objective-C interface to the Grand Central Dispatch system, NSOperation and NSOperationQueue.. Viewers then learn how to write thread safe code to ensure two threads can’t conflict while running. . Finally, the lesson goes into more depth on an aspect of properties related to threading, atomic accessors.

Duration: 00:38:19  File Size: 106 MB

Lesson 11

Lesson 5 (Advanced): Objective-C Design Patterns

Lesson 5, “Objective-C Design Patterns,” covers the concept of design patterns and why it’s beneficial for developers to learn them. The lesson goes into the types of design patterns that exist in Objective-C and why they are important to understanding the language as a whole. Then, viewers are shown how to implement the Singleton design pattern in Objective-C, which is one of the most commonly used design patterns. After that, viewers learn about the Delegate pattern and the Observer pattern.

Duration: 00:31:00  File Size: 91 MB

Lesson 12

Lesson 6 (Advanced): Data Serialization

Lesson 6, “Data Serialization,” covers how to write data out to disk, send data up to a network service or web service, or receive data from a web service, all of which require serialization. First, viewers learn how to use the NSCoding protocol in objects to serialize custom objects and write them out to a disk. Next, viewers learn about property lists which store Dictionaries and arrays easily. Finally, viewers are shown the JSON serializer, which is a new addition to Objective-C. Using this system framework, developers can convert objects into correctly formed JSON strings and vise versa.

Duration: 00:21:40  File Size: 98 MB

Lesson 13

Lesson 7 (Advanced): Objective-C Best Practices

Lesson 7, “Objective-C Best Practices,” covers ideas that will help viewers to write code that is cleaner and more flexible. First, the lesson covers the changes that Objective-C has gone through in the last few years and, as a result, how the code developers write can be cleaner and clearer. Next, viewers learn how to best encapsulate their data in classes. Viewers then learn how to properly use properties and dot notation. Finally, viewers learn how to prevent non-ARC code from using your ARC code.
