WordPress asking for FTP username/password?

By Josh Highland in tutorials, wordpress

Are you annoyed with your wordpress install asking you for your FTP cradentials everytime you try to upgrade a plugin? I know I was.  Thankfully, there’s a simple solution which will save the FTP login (username/password/server) so WordPress stops asking you for them.  Here’s how you do it.

  1. Locate your WordPress root diectory and find the “wp-config.php” file.
  2. Edit the file and insert this somewhere in the middle as it’s own block, we normally put it after the mysql username/password block.
define("FTP_HOST", "localhost");
define("FTP_USER", "yourftpusername");
define("FTP_PASS", "yourftppassword");

Once you’ve made that edit, save the file and voila! No more punching in your ftp username and password all the time.

iPhone Keyboard Covers Text Field

By Josh Highland in iPhone app dev, tutorials

Recently while developing an app, I ran into an issues where the iPhone keyboard was sliding up and covering the text field. I did some quick searching on the on the internet an came across some sample code on StackOverflow (http://stackoverflow.com/questions/1247113/iphone-keyboard-covers-text-field)

I took the code that was given and spun it for my own uses. After placing the code in the project, I linked the hidden textFields ‘Editing Did Begin” and “Editing Did End” events to the “slideFrameUp” and “slideFrameDown” methods.

The end result works great!

-(IBAction) slideFrameUp;
{
[self slideFrame:YES];
}

-(IBAction) slideFrameDown;
{
[self slideFrame:NO];
}

-(void) slideFrame:(BOOL) up
{
const int movementDistance = 50; // tweak as needed
const float movementDuration = 0.3f; // tweak as needed

int movement = (up ? -movementDistance : movementDistance);

[UIView beginAnimations: @"anim" context: nil];
[UIView setAnimationBeginsFromCurrentState: YES];
[UIView setAnimationDuration: movementDuration];
self.view.frame = CGRectOffset(self.view.frame, 0, movement);
[UIView commitAnimations];
}

Don’t use NSLog anymore!

By Josh Highland in iPhone app dev, tutorials

NSLog is a convenient way to output logging information from your iPhone app. NSLog is most commonly used by developers for debugging purposes. The problem with adding NSLog statements in your code is that you have to remove them or comment them out before you can submit your application to the app store. Apps that output data via NSLog will not be approved into the app store.

I would like to show you how I handle this delema. Start by opening the “_Prefix.pch” file.

next, add the following lines to the file

#define DEBUG_MODE

#ifdef DEBUG_MODE
#define DebugLog( s, ... ) NSLog( @"<%@:(%d)> %@", [[NSString stringWithUTF8String:__FILE__] lastPathComponent], __LINE__, [NSString stringWithFormat:(s), ##__VA_ARGS__] )
#else
#define DebugLog( s, ... )
#endif

In your code, replace “NSLog” with “DebugLog”. THATS IT!

DebugLog adds some new functionality to NSLog. It will now output the file name and line number of the Debug statement.

The best part of this is that its very easy to disable when its time to create a release build of your code. Simple comment out the “#define DEBUG_MODE” line im the “_Prefix.pch” file.
