$ make-ssl-cert generate-default-snakeoil --force-overwrite

It creates the following files:

• /etc/ssl/private/ssl-cert-snakeoil.key
• /etc/ssl/certs/ssl-cert-snakeoil.pem

Activate Apache SSL module:

$ a2enmod ssl

Activate Apache default ssl virtual host:

$ a2ensite default-ssl

Restart Apache:

/etc/init.d/apache2 restart

You should now see the following page on your webserver:

It works!

This is the default web page for this server.

The web server software is running but no content has been added, yet.

My jailbroken device was on a 3.1.3 firmware with Cydia installed. After trying different 4.x firmwares, I googled this error message and found an interesting thread here.

I followed their advice and it worked:

• Install TinyUmbrella,
• Clicked on my device,
• went to Advanced tab and unchecked “Request SHSH from Cydia”,
• Started TSS Server,
• Entered Recovery,
• and finally in iTunes clicked on Restore (with option key) and selected a 4.1 firmware,
• done!

This means while compiling the extension, compiler can’t find mysql librairies. It’s because they haven’t been installed in standard include folders. They actually are in /usr/local/mysql.
To indicate to the compilation process to check this folder you need to add the following parameter to the command line:

$ sudo gem install dm-mysql-adapter --no-rdoc --no-ri -- --with-mysql-dir=/usr/local/mysql/

That’s exactly what I was thinking!

Browsing WordPress Plugin Directory, I found Editorial Calendar.

This plugin shows you all your posts through a calendar view instead of the classic list view:

You can also manage your posts, drag and drop between dates, etc… A must have when you schedule your posts.

Compilation was always ending up with the following message:

/.../build/Debug-iphoneos/xxxxxx.app: CSSMERR_TP_NOT_TRUSTED
Command /usr/bin/codesign failed with exit code 1

I checked my provisioning profiles, certificates and everything and couldn’t find a solution.

Finally, while browsing the iOS Provisioning Portal, I read this under my Development Certificate:

*If you do not have the WWDR intermediate certificate installed, click here to download now.

I downloaded this certificate and added it to Keychain Access:

I compiled my app again and it worked!

I don’t know why this certificate disappeared during my MacBook migration…

Since iOS 5.0, UIButton and UIBarButtonItem have a tintColor property.

You may have noticed that the tint property is not available for UIButton and UIBarButtonItem.

Two common techniques to change the color, you can find around are drawing button with CoreGraphic or using a stretchable UIImage.

Lately, I found a new technique based on UISegmentedControl which you can use the tint property to change the color of your button. This control can be tweaked to have only one segment with a UIButton style (UISegmentedControlStyleBar).

A standard UISegmentedControl

Tweaking the control

We will now create a UISegmentedControl with one segment and set its tint color:

UISegmentedControl *button = [[[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Add", nil]] autorelease];
button.frame = CGRectMake(0, 0, 160, 33);
button.center = self.view.center;
button.momentary = YES;
button.segmentedControlStyle = UISegmentedControlStyleBar;
button.tintColor = UIColorFromRGB(0x0000DD);
[self.view addSubview:button];

Compile your code, your button will look like the following screenshot:

Refer to the UISegmentedControl class reference for a detailled explanation of its properties.

I used a macro in this code to define my tint color. Macro definition is:

#define UIColorFromRGB(rgbValue) [UIColor \
  colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 \
  green:((float)((rgbValue & 0xFF00) >> 8))/255.0 \
  blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]

You can read more about defining macro or function here and here.

In a toolbar

You can also use this technique to tint UIBarButtonItem used in UIToolBar.

UIToolbar *toolbar = [[[UIToolbar alloc] init] autorelease];
toolbar.barStyle = UIBarStyleDefault;
[toolbar sizeToFit];
toolbar.frame = CGRectMake(0, self.view.frame.size.height-44, self.view.frame.size.width, 44);
[self.view addSubview:toolbar];

/* Create our tinted buttons */
UISegmentedControl *button = [[[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Add", nil]] autorelease];
button.momentary = YES;
button.segmentedControlStyle = UISegmentedControlStyleBar;
button.tintColor = UIColorFromRGB(0x0d9c23);

UIBarButtonItem *barButton = [[[UIBarButtonItem alloc] initWithCustomView:button] autorelease];
UISegmentedControl *button2 = [[[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Delete", nil]] autorelease];
button2.momentary = YES;
button2.segmentedControlStyle = UISegmentedControlStyleBar;
button2.tintColor = UIColorFromRGB(0xC84131);
UIBarButtonItem *barButton2 = [[[UIBarButtonItem alloc] initWithCustomView:button2] autorelease];

[toolbar setItems:[NSArray arrayWithObjects: barButton, barButton2, nil]];

You now have a toolbar with 2 tinted buttons that look like that:
