Remove existing files from the repository:
find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch
Add this line:
.DS_Store
to the file .gitignore
, which can be found at the top level of your repository (or create the file if it isn't there already). You can do this easily with this command in the top directory:
echo .DS_Store >> .gitignore
Then commit the file to the repo:
git add .gitignore
git commit -m '.DS_Store banished!'
Compare method
Either you implement a compare-method for your object:
- (NSComparisonResult)compare:(Person *)otherObject {
return [self.birthDate compare:otherObject.birthDate];
}
NSArray *sortedArray = [drinkDetails sortedArrayUsingSelector:@selector(compare:)];
NSSortDescriptor (better)
or usually even better:
NSSortDescriptor *sortDescriptor;
sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"birthDate"
ascending:YES];
NSArray *sortedArray = [drinkDetails sortedArrayUsingDescriptors:@[sortDescriptor]];
You can easily sort by multiple keys by adding more than one to the array. Using custom comparator-methods is possible as well. Have a look at the documentation.
Blocks (shiny!)
There's also the possibility of sorting with a block since Mac OS X 10.6 and iOS 4:
NSArray *sortedArray;
sortedArray = [drinkDetails sortedArrayUsingComparator:^NSComparisonResult(Person *a, Person *b) {
return [a.birthDate compare:b.birthDate];
}];
Performance
The -compare:
and block-based methods will be quite a bit faster, in general, than using NSSortDescriptor
as the latter relies on KVC. The primary advantage of the NSSortDescriptor
method is that it provides a way to define your sort order using data, rather than code, which makes it easy to e.g. set things up so users can sort an NSTableView
by clicking on the header row.
