iphone - Will using three20 make my app slower? -

i want utilize three20's ttthumbsview & ttphotoview build grindr. instead of (1) subclassing these classes, i'd prefer (2) analyze them , build take necessary code & tweak accordingly. why? because concern alternative (1) increment download size of our app & slow it's performance. (another thing want ues three20's caching, don't understand because right we're using core data. how three20 caching work?)

if i'm using part of three20, when compile app, build in other code that's not beingness used? or leave out? if leaves out, gives me hope maybe alternative (1) won't create app lot larger download.

in terms of performance (speed). three20 run fast? there's lot of subclassing going on. doesn't slow things down? facebook iphone app seems pretty good, , uses three20, right?

what think?

thanks!

there's quite few questions here:

analysing three20 code: people seek this, seems not many people have success this. here's illustration of 1 project gave up: http://github.com/enormego/photoviewer (the history in git believe, can go , see achieved before gave up)

three20 caching: can't help there; might want inquire separate question that. it's best inquire 1 question per question :)

size of three20: believe these views have lot of dependencies other three20 classes, whilst necessary code built in, that's quite lot of code.

speed: yep, it's iphone facebook uses, should fine there. in fact that's main reason people utilize three20 - it's hard fast, photoviewer, , three20 open source project i'm aware of has done it.
