问题 Is there a way to use assembly code inside Objective C program. I am developing an application for OSX and wanted to use assembly code alongside the Objective C code. I searched the internet and found this But I am not able to implement any of these methods successfully. Any help will be greatly appreciated. 回答1: Yes, of course. You can use GCC-style inline assembly in Objective-C just like you would in C. You can also define functions in assembly source files and call them from Objective-C.

问题 I've tried adding a test target on Xcode 5 using the Add Target -> Add Cocoa Touch Unit Testing Bundle. However, when I run the test, I get the following error: 2013-09-24 10:43:14.446 Stack Exchange[48895:c07] Error loading /Users/arielitovsky/Library/Developer/Xcode/DerivedData/MyApp-fjegcztcnwxqdfdimhonqzzqpdwr/Build/Products/Debug-iphonesimulator/Stack Exchange Tests.xctest/Stack Exchange Tests: dlopen(/Users/arielitovsky/Library/Developer/Xcode/DerivedData/MyApp

问题 Just stumbled across this today. I am getting warnings in Xcode 4.6 if I try to access the CALayer without importing <QuartzCore/QuartzCore.h> . The same however works fine in Xcode 5. 回答1: Yes, <QuartzCore/QuartzCore.h> is automatically included, but this seems to be more a side effect than intended, because it is included only indirectly: <UIKit/UIKit.h> includes <UIKit/UISlider.h> , in the iOS 7 SDK, <UIKit/UISlider.h> includes <QuartzCore/QuartzCore.h> , due to new instance variables in

问题 I'm using the instructions here to integrate Core Plot into my iOS Xcode 5 project and am having no end of issues. I tried using the Static Library Install but it seems this refers to 1.4 as there is no directory called CorePlotHeaders though if I try to use 1.4 I run into runtime issues. I've then tried to drag the CorePlot-CocoaTouch.xcodeproj as described in the Dependent Project Install but this only copies it as if its a file and not the whole project. Is there more current instructions

问题 Last week I asked a question about a Simulator bug with NSAttributedString not displaying: iOS 7 Simulator Bug - NSAttributedString does not appear Unfortunately it now appears this is not a simulator bug but an iOS 7 bug. I have now reproduced this issue on an iPhone 5 device. The bug appears to be the combination of using NSUnderlineStyleAttributeName & NSParagraphStyleAttributeName as attributes for a NSAttributedString. I have only tested on two iOS 7 devices so far, and the issue has

问题 Just got stuck with this error while I'm trying to publish an app to app store. Sorry because i cant copy-paste the error code so I will post an image in my question. 回答1: Are you sure the 568h file is actually in PNG format? Also make sure that you provided support for iphone 5 for all your screens? Only adding Default-568h@2x.png is not gaurantee for iphone 5 support. You have to check for framing of all your view for iphone 3.5" and 4" device. You can do the framing by code or autoresizing

问题 I have tried a lot of options, but can't find the solution for this problem. I created a Core Data file and named the entity Account, Created an string attribute called username. Then edited the class of the entity to NSManagedObject, not sure if this is right. Now, the following code is in my LoginViewController: - (void)viewDidLoad { [super viewDidLoad]; ITAppDelegate *appDelegate = (ITAppDelegate *)[[UIApplication sharedApplication] delegate]; NSManagedObjectContext *context = appDelegate

问题 I understand the old Struts and Springs method of aligning, sizing and distributing views in Interface Builder. However, I cannot seem to figure out how to evenly distribute views using auto layout with Xcode 5. There was a way to do it using Xcode 4, but that option is gone. I have 7 buttons arranged in a vertical stack. On a 3.5" layout, it looks great. When I preview the screen in the 4" layout, all of the buttons remain tightly packed and there is a large amount of space below the last
