XCode Developer API - Object Library - Objects Disappearing

本秂侑毒 提交于 2019-12-06 08:35:05
问题 Fairly new to the Xcode Developer API and need a little help. When a project is first opened in Xcode, the Object Library displays the full list of UIKit objects available (and other linked frameworks I believe). However, when I switch files in the project navigator to/from any file (.m, .h, .xib, etc), the Object Library list changes; most of the objects are missing - such as NSButton, NSTableView etc. The standard objects are still visible - Label, Round Rect Button, Text Field, etc.

UIViewController's initWithNibName: a reason behind this design?

I tend to agree with Joe Conway’s and Aaron Hillegass’s analysis, as reported today by Ole Begemann in http://oleb.net/blog/2012/01/initWithNibName-bundle-breaks-encapsulation/ Basically, they state that the NIB's filename is an implementation detail of the corresponding UIViewController class, and that it is not the business of the calling class to pass in the NIB's filename in the init method. I was wondering if there was any particular reason for this design choice from the creators of AppKit/UIKit, or if it is merely a mistake — and, in the latter case, why it wasn't corrected when UIKit

How to change dynamically the xib of a UIVIewController

ぃ、小莉子 提交于 2019-12-06 05:54:28
I have an UIVIewController "controller1" for instance. This controller is instanciated with initWithNibName... with "file1.xib". I want to dynamically change the xib file of my "controller1" to "file2.xib" To resume : "controller1" <-> "file1.xib" and I want to dynamically have : "controler1" <-> "file2.xib" How can I do this ? Hope I was clear. When you want to change views in a UIViewController just just use this code: NSArray *nibObjs = [[NSBundle mainBundle] loadNibNamed:@"file2" owner:self options:nil]; UIView *aView = [nibObjs objectAtIndex:0]; self.view = aView; I have two responses : 1

Xib for iPhone and iPad

Deadly 提交于 2019-12-06 05:24:50
问题 I have a Xib for iPhone and I need a similar view for iPad, only iPad size. What is the best way of doing this? Can you put both views in the same Xib and somehow specify which one is shown? Or do I need to be make 2 Xib files and 2 classes? 回答1: I ended up using 1 class. I set the file owner of both XIB files to this same class. I just used the name of the XIB file So I have 2 xibFiles, iPadXib.xib and iPhoneXib.xib NSString *nibFileName = (iPadVersion) ? @"iPadXib" : @"iPhoneXib";

Which “Top-Level Objects” is Apple talking about in the Memory Management Programming Guide?

≯℡__Kan透↙ 提交于 2019-12-06 01:59:37
问题 In the Memory Management Programming Guide for Cocoa Apple talks about Top-Level Objects. They say, that I need an Outlet for each of them. If there are any top-level objects you do not store in outlets, however, you must retain either the array returned by the loadNibNamed:owner:options: method or the objects inside the array to prevent those objects from being released prematurely. So what exactly do they mean with "top-level object"? I would say they talk about the root view and window.

Pyqtgraph with anaconda python on MAC gives nib error

I'm trying to use the pyqtgraph with anaconda python on Mac os Python 2.7.5 |Anaconda 1.6.1 (x86_64)| (default, Jun 28 2013, 22:20:13) [GCC 4.0.1 (Apple Inc. build 5493)] on darwin I installed pyqtgraph with pip install pyqtgraph , which seemed to work fine. However, if I run any command from the library I get this error: Qt internal error: qt_menu.nib could not be loaded. The .nib file should be placed in QtGui.framework/Versions/Current/Resources/ or in the resources directory of your application bundle. I found this SO thread , which seems to be related to C++ app. In my case I have no

How can I programmatically access UI elements in a NIB without 'wiring' them?

不想你离开。 提交于 2019-12-05 22:27:17
问题 I'm contemplating writing some helper functions to make it easier to do simple changes to the UI elements in my iPhone NIB. Mainly - I want to access a UILabel, or other element, via its Name in Interface Builder. Is this possible? Is there a smarter approach? Example Say I want to make a super simple iPhone app that displays 'Hello World'. I start a new project and then open the NIB and drag a UILabel into my view and give it a 'Name' of 'LblMain'. Now, presuming that I've included my handy

Should design separate Nib file for both English & Arabic version.Please help me. 来源: https://stackoverflow.com/questions/19403261/ios-how-to-build

Am I right in saying initWithNibName:bundle is used to manually load nib files and that initWithCoder would be used as an alternative?

折月煮酒 提交于 2019-12-05 13:10:57
I can't use initWithNibName:bundle seeing as I'm now using the latest XCode (5). After some research I found an alternative: initWithCoder. Example: - (id)initWithCoder:(NSCoder *)aDecoder { self = [super initWithCoder:aDecoder]; if (self){ // code here } return self; } What I'm trying to understand is how this is an alternative to initWithNibName? Currently studying with a big nerd ranch book for ios which was written for ios6 and previous versions of xode and experimenting with the coreLocation framework. In the code below I've replaced the initWithNibName. I also done this in an earlier

Performance penalty for using NIB files?

前提是你 提交于 2019-12-05 11:56:23
I am curious to know if anyone has any experience comparing the load time performance of iPhone apps with views laid out in NIBs vs. views laid out entirely programmatically (i.e. instantiating UITextView, adding it to the view, instantiating UIButton, adding it to the view…). If I want a simple app to load lightning fast, would it be better to forgo using a NIB (well, XIB technically) and instead create view elements programmatically? Is the time spent loading and parsing a NIB sufficient enough to make a noticeable difference? I've noticed that loading complex interfaces on the iPhone with
