| Similar to MacHeist, which features a bundle of apps by independent Mac developers, iPhoneSpree is giving away bundles of apps — but you don’t have to buy anything to enter. There are 80 levels of winning, with the top 1st-3rd prize winners receiving all 18 apps in the bundle (full list here). You can enter via the website or Twitter. |
1. NSURLConnection
For those who were wondering about this (and I was).
Really, yes, NSURLConnection knows how to handle cookies and does it by default.
You don’t have to manage it by hand.
2. Draw a glow
If you want to reproduce visually the highlight you can see on a UIToolbar button, you can use the following code sniplet :
void evaluate(void *info,const float *in, float *output) {
float x=in[0];
float _C0[4]={1,1,1,0};
float _C1[4]={1,1,1,1};
int i;
float factor;
x = 1 - x;
float c = 0.3;
float b = 1;
factor = exp(-(x - b) * (x - b) / (2 * c * c));
for(i=0;i<4;i++)
output[i] = _C0[i]+factor*(_C1[i]-_C0[i]);
}
- (void) drawRect:(CGRect)rect
{
CGColorSpaceRef space;
CGFunctionRef function;
CGShadingRef shading;
float radius;
float range[8]={0,1,0,1,0,1,0,1};
float domain[2]={0,1};
CGFunctionCallbacks callbacks={0,evaluate,NULL};
CGPoint center;
CGRect glowRect;
CGContextRef context;
glowRect = [self glowRect];
context = UIGraphicsGetCurrentContext();
CGContextSaveGState(context);
CGContextTranslateCTM (context, CGRectGetMinX(glowRect),
CGRectGetMinY(glowRect));
CGContextScaleCTM (context, glowRect.size.width, glowRect.size.height);
space = CGColorSpaceCreateDeviceRGB();
function = CGFunctionCreate(self,1,domain,4,range,&callbacks);
radius = 0.5;
center.x = 0.5;
center.y = 0.5;
shading = CGShadingCreateRadial(space, center, 0, center, radius, function, NO, YES);
CGContextDrawShading(context, shading);
CGShadingRelease(shading);
CGColorSpaceRelease(space);
CGContextRestoreGState(context);
}

In the iPhone SDK, strange things seems to happen with UINavigationBar.
You have a UINavigationBar at the top of your screen. Then, you can add some widgets (UIView) below the navigation bar.
But it seems that if you try to touch thoses views. UIEvent won’t be forwarded to them if you touch just under the navigation bar.
It seems that in a zone just under the navigation bar, of about 8 pixels height, events won’t be sent to your views but will be forwarded to the navigation bar.
It’s nice since, then, UIButtonBarItem in the navigation bar will be easy to touch because if you miss them and touch under the navigation bar, this will activate them anyway.
It’s also some kind of bug since when you place a view that is 30 pixels, only (let’s say) 22 pixels of the bottom of the view will be touchable and the top part of the view will forward events to the navigation bar and it’s not useful if there are no buttons in the navigation bar.
In the following screenshot : for both button A and B, the the part on top of the red zone is not touchable.
In my application, the zone is even larger (about 15 pixels). I did not analyze yet what it could be due to.

I’m working on software for iPhone.
2. a word on dequeueReusableCellWithIdentifier:
Did you thought – [UITableView dequeueReusableCellWithIdentifier:] was only for performance issue ?
In fact, this is mandatory when you have to call reloadData at any time.
It has some bug in the following case :
- highlight the cell by touching the cell
- reloadData on the UITableView
- then, touch up to select the cell
The UITableView will try to use the highlighted cell instance (which may have been dealloc’ed) when you touch up instead of using the new created cell.
So that this will crash.
It looks that the workaround is to use the following method of UITableView :
- (UITableViewCell *)dequeueReusableCellWithIdentifier:(NSString *)identifier
3. edit mode and reloadData
Don’t try to call – reloadData on UITableView while it is in edit mode.
This will have a buggy behavior, especially when you call reloadData while the user is touching-dragging the rows to move them.
The workaround is to call reloadData when you are back from edit mode.
4. disable move of rows
– (NSIndexPath *)tableView:(UITableView *)tableView targetIndexPathForMoveFromRowAtIndexPath:(NSIndexPath *)sourceIndexPath toProposedIndexPath:(NSIndexPath *)proposedDestinationIndexPath
if you try to return sourceIndexPath as result, this will have a bad behavior. You tableview will be broken. The dragged cell at the end of drag will be at a strange position in the tableview.
libetpan 0.57 has been released.
This is for the needs of claws-mail.
Thanks to claws mail, releases of libetpan occur more often 
I am also thinking about writing an API to produce messages more easily.
This will be based on the work done in etpanX. If you think about an API which is currently hard to use, just tell me.
For hype-ness purpose, I am writing this from my iPhone 3G, with wordpress iPhone application.
