Ios – What’s the best way to develop a sideswipe menu like the one in Facebook’s new iOS app

cocoa-touchiosobjective c

It appears that side-swipe menus are becoming a more common interface element as more information gets crammed into each iPhone app. Facebook has included it in their latest version and the new Gmail app appears to include it as well. I was wondering if anybody had thoughts on the most efficient way of developing something like this as it's becoming a more common interface element. While I have my own thoughts on how to build this, I'm curious to hear what other people think.

There is a great library for this by Tom Adriaenssen: Inferis/ViewDeck

It's very easy to use and has a fairly large following.

EDIT:

For something a little more lightweight, check out: mutualmobile/MMDrawerController

It doesn't have all of the features of ViewDeck but is simpler to modify and extend.

Objective-c – the best way to unit test Objective-C code

Xcode includes XCTest, which is similar to OCUnit, an Objective-C unit testing framework, and has full support for running XCTest-based unit tests as part of your project's build process. Xcode's unit testing support is described in the Xcode Overview: Using Unit Tests.

Back in the Xcode 2 days, I wrote a series of weblog posts about how to perform some common tasks with Xcode unit testing:

Despite using OCUnit rather than XCTest, the concepts are largely the same.

Finally, I also wrote a few posts on how to write tests for Cocoa user interfaces; the way Cocoa is structured makes it relatively straightforward, because you don't have to spin an event loop or anything like that in most cases.

This makes it possible to do test-driven development for not just your model-level code but also your controller-level and even view-level code.

Objective-c – What’s the Best Way to Shuffle an NSMutableArray

I solved this by adding a category to NSMutableArray.

Edit: Removed unnecessary method thanks to answer by Ladd.

Edit: Changed (arc4random() % nElements) to arc4random_uniform(nElements) thanks to answer by Gregory Goltsov and comments by miho and blahdiblah

Edit: Loop improvement, thanks to comment by Ron

Edit: Added check that array is not empty, thanks to comment by Mahesh Agrawal

//  NSMutableArray_Shuffling.h

#if TARGET_OS_IPHONE
#import <UIKit/UIKit.h>
#else
#include <Cocoa/Cocoa.h>
#endif

// This category enhances NSMutableArray by providing
// methods to randomly shuffle the elements.
@interface NSMutableArray (Shuffling)
- (void)shuffle;
@end


//  NSMutableArray_Shuffling.m

#import "NSMutableArray_Shuffling.h"

@implementation NSMutableArray (Shuffling)

- (void)shuffle
{
    NSUInteger count = [self count];
    if (count <= 1) return;
    for (NSUInteger i = 0; i < count - 1; ++i) {
        NSInteger remainingCount = count - i;
        NSInteger exchangeIndex = i + arc4random_uniform((u_int32_t )remainingCount);
        [self exchangeObjectAtIndex:i withObjectAtIndex:exchangeIndex];
    }
}

@end
