Re: NSData from dispatch_data_t?

To get the size of the dispatch data you can call dispatch_data_get_size(dispatch_data_t) on it which would let you create an NSData object. https://developer.apple.com/documentation/dispatch/1452977-dispatch_data_get_size?language=objc -Ryan On Tue, Oct 30, 2018 at 7:26 PM Carl Hoefs wrote:

Re: Resend: array = [NSArray new] or array = [NSArray array]?

Under ARC there should be no appreciable difference. People who prefer +new will generally point out it's a keyword or operator in other languages so its meaning is not ambiguous. With manual reference counting, the difference is that +array is autorelease where as with +new your code is

Re: Core Data or not

To do it as one fetch you can set your predicate (or a sub predicate) as: [NSPredicate predicateWithFormat:@"%K in %@", primaryKey, keys] where primaryKey is the name of your ID property, and keys is an array of ID values which are "interesting" (as defined by the rest of your code). On Sat, Aug

Re: BOOL parameter passed as nil object

To answer your second question consider BOOL b = (BOOL)someObj; if someObj happens to equal something like 0x12345600 the value of b will be NO because casting from a pointer to a char will return the least significant byte. For your first question I don't know exactly but it doesn't look safe;

It may be advantage to log whether the model file exists and if it does exist if the permissions are correct. On Mon, May 11, 2015 at 1:06 PM, Alex Kac a...@webis.net wrote: So I've only seen this on OS X crashlytics, but one of my engineers says he's seen some logs on iOS as well. So I'm not

Re: NIB for Cocoa Standard Alert Sheet

You could create an UIAlertSheet show it and all that, then call recursiveDescription on the sheet which will tell you the description of all the views it has. You should be able to assemble a similar looking view with that info. On Mon, Apr 20, 2015 at 11:51 AM, Dave d...@looktowindward.com
