If you have something stuck in the trash that will just not delete when you empty it then simply
sudo rm -rf ~/.Trash/*
and it should all be gone.

Simple really.
1. Close XCode 4
2. Open Terminal and cd to your project folder
3. Type git init
4. Then git add .
5. And finally git commit -m “First commit of XCode project”
Reopen XCode and fingers crossed you are now all GITed up.

If you view or copy files from a Mac to a webserver it will place .DS_Store files in that directory. To fix add in your http.conf or .htaccess file
1 2 3 4 5 | <Files .DS_Store>
Order allow,deny
Deny from all
Satisfy All
</Files> |
Then restart Apache for this to kick in.

Working on a project that needed to show images with their information so looked into extracting EXIF data from the image itself rather than banging it into a db. Note this requires jpg files as png’s didn’t seem to work.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | NSString *myPath = [[NSBundle mainBundle] pathForResource:@"IMG_2733" ofType:@"JPG"]; NSURL *myURL = [NSURL fileURLWithPath:myPath]; CGImageSourceRef mySourceRef = CGImageSourceCreateWithURL((CFURLRef)myURL, NULL); NSDictionary *myMetadata = (NSDictionary *) CGImageSourceCopyPropertiesAtIndex(mySourceRef,0,NULL); NSDictionary *exifDic = [myMetadata objectForKey:(NSString *)kCGImagePropertyExifDictionary]; NSDictionary *tiffDic = [myMetadata objectForKey:(NSString *)kCGImagePropertyTIFFDictionary]; NSLog(@"exifDic properties: %@", myMetadata); //all data float rawShutterSpeed = [[exifDic objectForKey:(NSString *)kCGImagePropertyExifExposureTime] floatValue]; int decShutterSpeed = (1 / rawShutterSpeed); NSLog(@"Camera %@",[tiffDic objectForKey:(NSString *)kCGImagePropertyTIFFModel]); NSLog(@"Focal Length %@mm",[exifDic objectForKey:(NSString *)kCGImagePropertyExifFocalLength]); NSLog(@"Shutter Speed %@", [NSString stringWithFormat:@"1/%d", decShutterSpeed]); NSLog(@"Aperture f/%@",[exifDic objectForKey:(NSString *)kCGImagePropertyExifFNumber]); NSNumber *ExifISOSpeed = [[exifDic objectForKey:(NSString*)kCGImagePropertyExifISOSpeedRatings] objectAtIndex:0]; NSLog(@"ISO %i",[ExifISOSpeed integerValue]); NSLog(@"Taken %@",[exifDic objectForKey:(NSString*)kCGImagePropertyExifDateTimeDigitized]); |
Obviously change the image name and be aware that images loaded in a UIImageView seem to have their EXIF data stripped out.

I simply quote…
“For those using Interface Builder to layout your toolbar, it is also possible to do this using Interface Builder alone.
To add a label to a toolbar you need to add a generic UIView object to your Toolbar in IB by dragging a new UIView object over your UIToolbar. IB will automatically create a UIBarButtonItem that will be initialized with your custom UIView. Next add a UILabel to the UIView and edit the label graphically to match your preferred style. You can then visually set up your fixed and/or variable spacers as desired to position your label appropriately.
You must also set the background of both the UILabel and the UIView to clearColor to get the toolbar to show through correctly under the label.”
Genius and simple. Thanks to Matt R and Stackoverflow
