no multi-tasking! also heard that iOS4 takes up lots of memory. no wonder, my app is facing problem. really need to optimize the app in terms of memory access and usage.

just did a massive update to the xcode, itunes and iphone to the latest.
first thought is slow for mapkit rendering.
second is that compiling is much tighter now. what used to work for iPhone OS 3.13 doesn’t work for iOS4 for some cases, especially the memory intensive stuff for some Coredata calls that I made earlier. Need to optimize or remove some of the fetch. Seems like iOS4 is quite adamant on memory.
also, need to rework some of the google docs code that import into coredata.
was able to import earlier, not was busted.
did like the compiler and some enhance debugging tools in xcode.
looks like got lots to clean up and debug for version iOS4

As quoted by Steve Jobs in recent All Things D Conference near Los Angeles, “The iPhone would continue to have Google Maps”
Therefore, good to continue using Google Maps API with iPhone’s Mapkit.

Found some very good links and references from StackOverflow. Will look into it later.

Just found a great tutorial on using MapKit. Will try it out later with the application.

I have downloaded speadsheets before with GoogleDocs Spreadsheet API, but never with headers that have spaces in between them.
Was assuming that this will work with header titles with no spaces, but was wrong. Remove the spaces between the title wording and the API continue to work as before.
No sure if this is a bug, but it seem strange that header titles cannot have spaces between words.
Example Headers before, not working
Display Name E-mail Address
Example Headers after, working
DisplayName E-mailAddress
for (int count = 0; count < entriesCount; count++) {
entry = [[mEntryFeed entries] objectAtIndex:count];
listEntry = (GDataEntrySpreadsheetList *)entry;
customElements = [listEntry customElementDictionary];
enumerator = [customElements objectEnumerator];
while ((element = [enumerator nextObject]) != nil) {
kName = [element name];
kValue = [element stringValue];
NSLog(@”kName kValue %@”, kName, kValue);

iPhone 3.2 works for both iPad and iPhone platform. The iPad simulator is damn small within my Macbook display. Guess it’s part of Apple’s plan to encourage me to get a larger MacBook or a 20″+ display.
Quick look at the SDK shows some new APIs for displaying on iPad. With the larger screen estate, much more effort on designing the work areas. Need to read the updated UI guidelines for iPad.

Even though iPhone OS 4.0 beta 3 just release, I myself not in a habit to using beta. Been using 3.1 for quite some time and getting used to it.
Like the static analyzer and now it compiles faster than before. Using LLVM GCC4.2 compiler and like it much for the speed. Shows potential bugs which I need to optimized.

Was looking through the dev docs and trying to learn more about it. Guess what?
The Address Book classes doc are not updated. Have to search for the Address Book Programming Guide for iPhone OS in the net. This is much better doc as compared to the online xcode dev doc.
Now to work on that address book.
p.s
There are two Address Book API. One for MacOS X and the other for iPhone OS. The API for iPhone does provide the basic functionality that I need. However, I really want some functionality catered for MacOS X.

Downloaded the API about 2 weeks ago. Now’s the time to replace the existing 1.9.
Should be same for me as still using only the Spreadsheet API. Later, will need to find a way to store last modified file so as not to download if requested.
Maybe that’s for version 1+.
