Continuous zoom in MKMapView

[Miguel Arroz]

Hello,

  I'm trying to control a map view programmatically, and I need to zoom in and 
out with high accuracy (like when the user pinches it for zomming, the map may 
display an arbitrary level of zoom when the user stops touching the view).

  However, when I do it programmatically, with setRegion:animated: or 
setVisibleMapRect:animated:, the behavior is different than what I expect. It 
appears that the map view has some predefined zoom levels, and it will massage 
the region or rect I pass to those calls and adjust it to the nearest 
approximation for those predefined zoom levels. This prevents me from setting 
an arbitrary zoom level, or making a continuous zooming effect.

  Is there any way to tell the map view I want that specific region or rect, 
and not the approximation?

To carry this a bit further, your application might not even reside on a volume 
to which the user could /ever/ have write access, regardless of permissions. 
Read-only disk image? DVD? Read-only network share? These are all possible 
scenarios for which an application should be prepared.

(I realize the thread wound up being about iPad, but this is a good thing to 
point out in general.)

NSAttributedString is there so you can now do Core Text (which lets you draw
text in multiple styles). UITextView and UITextField still display text is a
single font and size. m.

It's on the "General" tab, not the "Build" tab. Look near the bottom, where the 
Base SDK popup is.

Please forgive this newbie question.  When I create a new

Where and how do I change "admin" and "__MyCompanyName__" so
I don't have to change every file after the creating?

Thank you,

Also, in recent versions of Xcode (maybe since 3.1, I can't  
remember), you can set the company name for source files on a per- 
project basis via the "Organization Name" field of the project info.  
I'd say this is the best solution in general, since it doesn't  
depend on a ridiculously obscure default like the other solutions.




Please post a picture or give more information on "Organization Name"  
in project info.  I right click the project in the tree, choose get  
info and am taken to the target build settings in which I do not see  
"Organization Name".


To what "Organization Name" field of the project info are you referring?

TCP_NODELAY is not in the man page. But your pointer made me remember the thing 
I needed:

int yes = 1;
setsockopt(CFSocketGetNative(aSocket), IPPROTO_TCP, TCP_NODELAY, (void *)&yes, 
sizeof(yes));

Thanks a lot,
