nsarray

I have some data like this : 1, 111, 2, 333, 45, 67, 322, 4445 NSArray *array = [[myData allKeys]sortedArrayUsingSelector: @selector(compare:)]; If I run this code, it sorted like this: 1, 111, 2,322, 333, 4445, 45, 67, but I actually want this: 1, 2, 45, 67, 111, 322, 333, 4445 How can I implement it? thz u. Expanding on Paul Lynch's answer, here's an example I have doing exactly this using a comparison method as a category on NSString . This code handles only the case of numbers followed by optional non-numeric qualifiers, but you could extend it to handle cases like "1a10" etc. if desired.

I have 2 nsarray, with the same values but in different order. NSArray * array1 = {0,1,2,3} NSArray * array2 = {2,3,1,0} I need a method to determinate if two arrays have the same values in a different order. Kind of -(BOOL) isSameValues:(NSArray*)array1 and:(NSArray*)array2; if ([[NSSet setWithArray:array1] isEqualToSet:[NSSet setWithArray:array2]]) { // the objects are the same } You can use NSCountedSet for that purpose: - (BOOL)isSameValues:(NSArray*)array1 and:(NSArray*)array2 { NSCountedSet *set1 = [NSCountedSet setWithArray:array1]; NSCountedSet *set2 = [NSCountedSet setWithArray:array2

I have two NSArray objects that I would like to be sorted the same. One contains NSString objects, the other custom Attribute objects. Here is what my "key" NSArray looks like: // The master order NSArray *stringOrder = [NSArray arrayWithObjects:@"12", @"10", @"2", nil]; The NSArray with custom objects: // The array of custom Attribute objects that I want sorted by the stringOrder array NSMutableArray *items = [[NSMutableArray alloc] init]; Attribute *attribute = nil; attribute = [[Attribute alloc] init]; attribute.assetID = @"10"; [items addObject:attribute]; attribute = [[Attribute alloc]

I have a plist: <plist version="1.0"> <array> <dict> <key>name</key> <string>Alabama</string> <key>abreviation</key> <string>AL</string> <key>date</key> <string>1819</string> <key>population</key> <string>4,627,851</string> <key>capital</key> <string>Montgomery</string> <key>largestCity</key> <string>Birmingham</string> </dict> <dict> <key>name</key> <string>Alaska</string> <key>abreviation</key> <string>AK</string> <key>date</key> <string>1959</string> <key>population</key> <string>683,478</string> <key>capital</key> <string>Juneau</string> <key>largestCity</key> <string>Anchorage</string> <
