NSUndoManager

Undo/redo capabilities are provided by the NSUndoManager class. The class, documented here, works by keeping a stack of messages that, if sent, would serially undo the last action, the penultimate action, and on back until arriving at the initial state.
Let’s use an example to illustrate how this works: our city, concerned with a perceived increase in the number of trucks plying our streets, has commissioned a census. City workers will tally truck traffic using an iPhone app. See a truck, tap a button. Oops! Mistook that Subaru Forester for a truck? Shake to undo.
We’ll start with working code that lacks undo/redo and add those capabilities. Grab the code to follow along:

Factory Unlocked iPhone 4 Prices

Factory Unlocked iPhone 4 Prices

The prices of factory unlocked iPhone 4 haven’t been announced yet by Apple. At the time of writing this post, Apple has announced iPhone 4 for five countries alone, and none of them have factory unlocked iPhone 4. Apple is expected to announce iPhone 4 in 55 more countries in July 2010 which might include countries like Hong Kong, Australia, Belgium etc which will definitely get legally unlocked iPhone 4 versions.

If we go by the prices of iPhone 4 in US, which are exactly same as those for iPhone 3GS models (whose prices were reduced after the launch of iPhone 4), we expect the cost of factory unlocked iPhone 4 in Hong Kong to be-

iPhone 4 – 16GB (factory unlocked): HK$ 5,388 i.e USD 695 (or 570 Euro) *approx*
iPhone 4 – 32GB (factory unlocked): HK$ 6,288 i.e USD 812 (or 667 Euro) *approx*

Beside HK, Apple stores in NZ and Australia might also get iPhone 4 but at not-so-cheap prices, as the service providers are only authorized to unlocked iPhone 4. The approximate expected prices of iPhone 4 are

iPhone 4 16 GB (factory unlocked):
New Zealand 1,150.00 NZD = 655.033 EUR = 791 USD
Australia 879.00 AUD, 617.287 EUR, 746.991 USD
iPhone 4 32 GB (factory unlocked):
New Zealand 1,349.00 NZD, 928.172 USD, 768.422 EUR
Australia 1,040.00 AUD, 882.469 USD, 730.121 EUR

KOLKATA: Eleven months after Apple's next-generation smartphone hit stores worldwide, the iPhone 4 was launched on Friday in India, the world's second biggest market for mobile phones.

Mobile phone carrier Aircel launched the iPhone 4 with a new pricing model, allowing customers to recover the upfront cost of the smartphone on select plans over 24 months, the company said in a press release. Aircel will charge Rs 34,500 for iPhones with a 16 GB capacity and Rs 40,900 for the 32 GB model, it said.

Declaring the roll-out of one of the most expected smartphones in the world by Bharti airtel here and in 34 other cities in India, Airtel CEO (West Bengal and Orissa) P D Sharma told media the iPhone 4 will create a separate space from the clutter of smartphones in the market, many of them having copied Apple features.

"iPhone 4 will stand out for its original applications and cater to the middle segment as well, with attractive pricing which will not create a pinch both in the long and short term," Sharma said on the sidelines of the launch here.

Asked about the delay of almost one year in the product arriving in India after its June launch in the US, Sharma said, "With third generation ( 3g) mobile networks only coming of age in recent times in India, there was no other option but the iPhone 4 to wait."

"The handset will be priced at Rs 34,500 with 16-GB capacity and Rs 40,900 with 32-GB capacity, which is attractive considering the long-term use. The set is powered by Apple's A4 (operating system), boasts of a retina display, FaceTime for video chat, 5-MP rear facing camera with LED flash and HD video recording," he said.

The iPhone 4 boasts a higher-quality screen and longer battery life than the previous model, he said, adding that Bharti already sells earlier models of the iPhone in India.

"With the high number of mobile users, smartphone market will grow in the country," he said.

The iPhone 4 was launched way back in June in the US, followed by other countries.

To the question if the pricing would offset the buying of the model at inflated rates over and above the $ 1500 price tag from the grey market, Sharma said that stage seems to have been over.

The iPhone 4 was launched in the city by Tollywood actress Paoli Dam, who was among the 35 celebrities in different cities of the country gifted a handset on the occasion of the launch.

"I am happy to possess one iPhone 4 from today. I have also been given a favourite number by Airtel, which I can memorise very easily. I am sure this handset will become a part of my accessory," Dam told media.

About whether she had been using Apple products earlier, the actress said, "I had been using Apple Mac."
