Problem
You subclassed UIView, you want to do some custom drawing in drawRect, but no matter what you do or where you draw, the background of the view remains black.

- (void)drawRect:(CGRect)rect {
 // Drawing code
 CGContextRef context = UIGraphicsGetCurrentContext();
 CGContextSetRGBFillColor(context, 0.0, 0.0, 1.0, 1.0);
 CGContextFillEllipseInRect(context, rect);
}

Solution
In the ViewController, which call the drawing class, add

myDrawingClass.opaque = NO;

- or even nicer. In the drawing class’ init function:

self.opaque = NO;

And not like that
- adding “self.opaque = NO;” in the drawRect: function
- CGContextClearRect(context, rect);
- CGContextSetAlpha(context, 0.5f);

hmm nice.

the logical thing to do.

instead of text messages, send images…

update: turning tiling on.
curl -F ‘image=@test.png;type=image/png’ -F ’tile=true’ -H ‘Expect:’ -u username:password http://twitter.com/account/update_profile_background_image.xml

second -F flag creates second form field.

update: same applies to user profile image
curl -F ‘image=@icon.png;type=image/png’ -H ‘Expect:’ -u username:password http://twitter.com/account/update_profile_image.xml

update: absolute image paths
curl -F ‘image=@/Users/x/Desktop/icon.png;type=image/png’ -H ‘Expect:’ -u username:password http://twitter.com/account/update_profile_image.xml

there seems to be a bug in the max shell object, preventing cd to work. it also does not like relative paths (~)…

Enable Debug Menu in Safari 4.0:

defaults write com.apple.Safari IncludeInternalDebugMenu 1

via http://trac.webkit.org/wiki/WebDevelopers

Also, an interesing option is to modify the .nib file of Safari and insert a new menu:

& wrap method in autorelease pool.
