I have a really simple App, with one view, one button with one activity when you press this button. The button is full screen size, as well as the image that is in it.I have it running on my iPhone 6 Plus perfectly, after spending a long time getting the Controller View, View Container, and Button sizes to work together so it is seen properly on the iPhone 6 plus, both hardware and virtual.The button and image are full screen size, and it took some fenagling to get even this to work for ONE iPhone size. LOL. The Controller View is one size, which is NOT the real life size of my iPhone 6 plus. It is larger. So the View Container is the correct size, along with the button. The image is PNG 401PPI 1080 x 1920 as Apple recommends for the iPhone 6 plus. It looks correct on my iPhone.My issue is the following: How do I now take my App, and create the other two sizes for the iPhone 5 and iPhone 4?I have scoured here and on the Web to absolutely no avail whatsoever. Nothing I have tried so far, has done anything but

I have this big piece of code which makes core data predicates based in user selection of sort criteria. the user either selects all categories, or all venues of one category or one/many venues of one category.when i select 1 venue of 1 category, the last else if (venues.count==1) is supposed to be executed. for some unknown reason it is executed twice! this makes the predicate nil the second time!i have been beating my head about it for sometime now and have checked for any accidental braces for loops etc.. nothing seems to be wrong. i know somewhere there is a silly mistake on my part. if u can please help me spot it out.thanks... //predicate for location NSPredicate *locationsPredicate; if ([_sortDictionary valueForKey:@_locationCategories]!=[NSNull null]) { NSExpression *categoryLHS, *categoryRHS; NSArray *categories = [_sortDictionary valueForKey:@_locationCategories]; categoryLHS = [NSExpression expressionForKeyPath:@location.category]; if (categories.count>1) { NSMutableArray *categoriesCom

On Xcode 7 b 6, if you open a project created in Xcode 6 with a Watch OS1 app, then select update to recommneded settings, it will convert the Watch OS1 app into a Watch OS 2 app.This didn't seem to happen on previous betas. I didn't notice this was listed in the list of changes that Xcode was going to perform on a project today, and now I have some Watch OS2 apps that I'd like to revert back to Watch OS 1 apps.Is there a step by step process to revert a converted Watch OS 2 target back into a Watch OS 1 target?And, I filed a bug report about this (22447746) because I don't think this is really the ideal process. At least initially, you are still going to have to support OS1 to some extent, so you don't want to delete the old OS 1 target. But, it might be convenient to duplicate the Watch OS1 target and convert the duplicate to Watch OS2. But, back to the original big question: how do I revert the OS 2 target to OS 1? I'd prefer to not have to recreate all the Watch OS1 targets if possible.

I have implemented Network drive mounting using NetFSMountURLSync with different protocols (AFP, SMB, NFS and NFS (Final cut protocol)). Below mentioned is my code to achieve it.Example url : smb:/ Example mount path : file:/ NSURL *url = [[NSURL alloc] initWithString:mountURLString]; NSURL *mountpath = [NSURL fileURLWithPath:@/Volumes/ isDirectory:YES]; CFMutableDictionaryRef mountOpts = CFDictionaryCreateMutable(NULL, 0, &kCFTypeDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks); CFDictionarySetValue(mountOpts, kNetFSMountAtMountDirKey, CFSTR(MountAtMountDir)); CFArrayRef mountpoints = NULL; NSInteger error = NetFSMountURLSync( (__bridge CFURLRef) url, (__bridge CFURLRef) mountpath, NULL, NULL , 0, mountOpts, &mountpoints);It works fine when Sandbox Mode is OFF but the above code doesn’t work when Sandbox mode is ON. It returns me error as 1 which is “Operation not permitted” according to the Error.h file. I know there are restrictions in Sandbox mode, but its important

Am I the only one who hates the big changes Apple makes this year? Why can't they make just small changes in Swift???? It's not hard to convert all my Code to Swift 2. It is IMPOSSIBLE. I get 9 errors, even if I could fix them and press the build and run Button I get 20 new errors. Every time. And most of them do really not make any sense. I will never ever switch to Swift 2. And if this means I can't build new Apps one day, that's ok. Even switching to Android is still better than switching from Swift 1 to Swift 2. I will not learn a completely new programming language every year. Because that's what Swift 2 is. Last year it was Swift. Now it's Swift 2. And next year? Will I have to learn Swift 3 which will also be a completely new language? No, thanks.
