iPhone development from a Java perspective (Jazoon '09)
- 16. One Big Difference No Source Code
- 18. Diving Deeper: The Platform
- 38. Patterns
- 42. Delegate Pattern
Editor's Notes
- Where do I work, experience
- make jokes about ridiculous data roaming charges blatant commercial
- maybe more details about this...
- (performance of a unix workstation 10 years ago) - fast startup - use for few seconds, switch off - start where you left off - fingers are fat, not mouse - people wear glasses (paraphrase) - no man pages, no manual
- Joke: “lets get this behind us”
- Image of tools / technologies involved, a diagram that will be used throughout the presentation
- the UI designer is an inegral part of the system
- also enthusiasm not finished
- perhaps with some images talk about unix scripts; compare with java - cost of abstracting away the OS Demo here?
- Demo - not finished - parallel to smalltalk
- screenshot
- talk about syntactic vs. semantic similarities what does this mean for a java developer
- ... of the standard library (very annoying and hindering) (i learned java by looking at the standard library sources)
- Close up the first impressions; intro about the platform and the langauge; old, been a while
- will talk about differences more than about similarities
- 2 things to remember; method call a.k.a. sending message syntax parameters embedded in the method signature verbosity. mention similarity to java in terms of references vs. primitives mention class objects, string literals,
- compiler here when you need it dynamic productivity
- Mention null-safe handling .?
- mention that we usually don’t use a prefix for the main application
- - talk about argument passing here - verbosity
- you can inherit constructors
- talk again about the dynamic nature of Objective-C
- NSString is usually the prime target e.g. UIKit adds drawing methods to the string class splitting a class into parts Visible when you compile / link against the framework that adds it
- compare with java
- THE biggest issue: - difficult to comprehend - constant cause of trouble - the source of almost every nasty bug we had
- wrapup
- Give a short talk about patterns in CocoaTouch. put an image
- events - UI events chain of command
- Compare to SAX parsing - handler - events (notifications) Extending through delegate instead of inheritance/composition one-to-one events
