UILabel HTML to attributed string conversion: odd font choice for text

I have formatted text delivered to the app as HTML that I am converting to a NSAttributedString and then assigning to a UILabel like this: NSDictionary* options = @{ NSCharacterEncodingDocumentAttribute: @(NSUTF8StringEncoding), NSDefaultAttributesDocumentAttribute:

iOS: Cannot connect to iTunes Store

I’ve been testing IAP in the sandbox store on a development iPod and just started getting this error in -paymentQueue:updatedTransactions: with (transaction.transactionState == SKPaymentTransactionStateFailed): Error Domain=SKErrorDomain Code=0 "Cannot connect to iTunes Store" UserInfo=0x1aa5e0

Re: Navigation Design question

Why not just make a common UIViewController subclass that manages the global menu button, and then subclass that class for each of the controllers that live on your navigation stack? If it contains the ivar for the UINavigationItem (marked @protected) instead of having that ivar in each of the c

I’m already doing downloads in my app using NSURLSession so I used my existing code to download and decode the data returned by the URL below and didn’t get an error. I am building against iOS 7.1 and I tried it out in the simulator. Doing a brief search, it seems like when others are running in

Re: Contribute some dictionary keys with registerDefaults

When you call -setObject:forKey:, it replaces the entire contents of that key, whether the object is a number, string, dictionary, etc. That’s the same behavior as if you called -setObject:forKey: on a regular dictionary when one of its objects is, itself, a dictionary. Depending on what you ne

Re: CABasicAnimation does not animate bounds.origin of a layer

First guess would be not to explicitly set -anchorPosition. It defaults to (0.5, 0.5), which refers to the middle of the bounds, and transforms (like scaling) are applied relative to that position. > On Sep 14, 2019, at 6:25 AM, Gabriel Zachmann via Cocoa-dev > wrote: > > Maybe, I haven't un

Swift -> Obj-C: return __kindof Something

I’m working on an Obj-C app that got started a bunch of years ago and thought that I would start migrating some of the smaller pieces over to Swift. Some existing Obj-C methods are of the form: + (nullable __kindof NSManagedObject) someFooThing; Right now I have class var someF

Re: Relieving memory pressure

For slide shows that I’ve seen, they typically display each image for several seconds at a time. If that’s the case, why can’t you just load the next image from disk on a background queue while the current image is being displayed and not have to worry about memory usage needed to cache multiple
