So I read the official documentation for iOS Bluetooth programming. Yesterday the test was successful and I want to write down the snacks, for later viewing.Let's get down to the truth.

Book Description In some ways, iOS 7 are the most radical change to IOS since the Software Development Kit (SDK) were released in IPhone OS 2 . The press and blogosphere has discussed every aspect of the new "flat" user interface and what it means for app developer S and users. Suffice to say, no IOS upgrade have required so many developers to red

Transferred from: http://www.myext.cn/other/a_30922.htmlComparing date sizes is a common problem in any programming language, and in iOS programming, you typically use NSDate objects to store a time (including dates and times, time zones), and the NSDate class provides a compare method for time comparisons. But sometimes you don't want to know the size of two dat

The framework packaging and swift programming languages have been introduced since iOS 8.0. We can mainly use the SWIFT programming language to package our own code into the framework. However, the current Xcode 7.x is not too smart to automatically import the framework package, so you need to do some cleanup.First, when the framework is generated, structures, cl

1. What is a view?The view is displayed as a rectangular area on the phone, which is a subclass of UIView or UIView.Views can be either generated from Xib or generated in code.2. WindowsA window is a uiwindow or a subclass of it.The top level of the view structure is the app's window.The window must be filled with the screen of the device, so the frame of the window must be set to the bounds of the screen.(I'll explain the difference between frame and bounds later)The code is as follows:Objectiv

Disclaimer: the entire article is either my speculation and desire, or a complaint. Introduction: criticize Objective-C Programmers, onlookers, and scholars have criticized Objective-C for a long time. Complaints about languages and APIs include the lack of multiclass groups, substrings (slices), hash or syntax-level structures, lack of programming templates, lack of namespaces, and lack of default parameters for methods; operator overload is missing;

IOS development-multi-thread programming 1. "power saving, smoothness, high-quality applications, fast response, good user experience ......" It may be the Apple system in the eyes of many users. 2. In the age when mobile phone manufacturers struggled for CPU clock speed, 4-core and 8-core, Apple still insisted on dual-core, and the iphone user experience remained strong. How to optimize

Functional programming in the function f (x) emphasizes the stateless, in fact, the emphasis is to lock the state inside the function, a function that does not depend on any external state, only depends on its entry parameter value, once the value is determined, the function returns the result is OK. Some people may feel that the entry is also the state, is the external incoming state, in fact, I said before the variable will have a state, the value i

There are a few key points to note when writing iOS clients using the rest service: Never use synchronous network calls. even in a background thread, the synchronization call does not report progress. Another reason is that if you want to cancel a synchronization request for a background thread, you can only end this thread, which is also not a good idea. In addition, there is no control over the number of network requests in the application, wh

Most of the notes are from: objective-c Advanced Programming (iOS and OS Multithreading and memory management), a bit of a long time, even GCD Online said no need to manually release releases, but the book emphasizes the use of GCD need to manage their own count.First of all, what is GCD?This is an API for Apple to make it easier for developers to focus on the task execution content in multi-threading, the

Book Description “About a year ago, noticing that Apple had not updated Objective-C much over the past few years, I got intimations that they were working on a new language or framework for iOS development, and even suggested it to my friends at work. They laughed and said, “Then you will have to write your book from scratch.” They were right; this edition is almost a whole new book”Excerpt From: Vandad Nahavandipoor. “
