Shazron Abdullah commented on CB-93:
------------------------------------
I just tested the 1.5.0 code, it definitely crashes during runtime for an iOS 3
device right now because of some iOS 4 code, namely registering for
pause/resume lifecycle events that we didn't guard for, for devices < iOS 4.
The fix is to guard the affected code using this:
{code}
NSString* systemVersion = [[UIDevice currentDevice] systemVersion];
BOOL isLessThaniOS4 = ([systemVersion compare:@"4.0" options:NSNumericSearch]
== NSOrderedAscending);
if (!isLessThaniOS4) {
// do your thing!
}
{code}
But I'm wondering if this is worth it since we are moving away from iOS 3.

> Support iOS 4.2 going forward (in 1.4?) since it offers the most features
> built-in to the UIWebView:
> http://www.mobilexweb.com/blog/safari-ios-accelerometer-websockets-html5
> On the native Objective-C side, supporting iOS 4 will also allow us to use
> blocks http://pragmaticstudio.com/blog/2010/7/28/ios4-blocks-1 which is a
> fundamental technology used in all of their framework APIs since iOS 4
> Risk factors:
> * Plugin problems - plugins using blocks in native code cannot be used on iOS
> 3. This can be mitigated with support for PhoneGap versions (as well as built
> in macros for iOS versions) in pre-processor macros, so this can be
> conditionally compiled. This can be solved with versioning in our future
> proposed plugin packaging
> * Possibly maintaining a iOS 3.x branch at the last iOS 3.x supported
> PhoneGap version for bug fixes -- for those that want to still use that
> version -- don't really want to do this though
> We stopped iOS 2.x support when iOS 4.x came out (thus, we usually only
> supported one version back from the current OS version).
> [iPhone]
> The oldest iPhone to have iOS 4.2 support is the iPhone 3G (released July
> 2008 - 3+ yrs old, discontinued). Current iPhone is the 4S, 3 models ahead.
> [iPod Touch]
> The oldest iPod Touch to have iOS 4.2 support is the iPod Touch 2nd
> Generation (released Sep 2008 - 3+ yrs old, discontinued). Current iPod Touch
> is the 4th Gen, 2 models ahead.
> [iPad]
> The oldest iPad to have iOS 4.2 support is the iPad 1 (released April 2010,
> 1+ yrs old, reportedly discontinued). Current iPad is the iPad 2, 1 model
> ahead.
> *Essentially, we would drop device support for these models: original iPhone
> and iPod Touch 1st Generation*
