I just recently in the development of a mall project, the implementation of a simple control, and we share it. The effect of the control is similar to the Baidu glutinous rice or the United States Group level Two menu, I developed iOS client menu function, a direct reference to git a project, the corresponding UI effect: In fact, the effect looks good. After the development of iOS, you are ready to deve

iOS Location-normal location (no map)-Anti-geocoding (get specific location), the following code to explain to everyone, the code is as follows: #import The use of iOS Baidu map (general positioning, anti-geo code) 1. First accept the basic map function Create a new map class, xib drag also line, my side is the code implementation. _mapview = [[Bmkmapview alloc]initwithframe:cgrectmake (

The following through the way to share the information in this area, the specific contents are as follows. Compared to Google's ban on advertising interception, Apple's attitude is diametrically opposed, following the Mac version of Safari to join the advertising interception tool, the upcoming iOS9 to Safari also introduced a content interception plug-in-content blocker, And developers can use the latest XCODE7 development and use the iOS 9 simulato

It is normal to encounter a program crash in iOS development, how to catch exception information when a program crashes and notify the developer? Here's how to implement this in iOS: 1. Add an exception capture listener at the start of the program to handle the callback action when the program crashes Copy Code code as follows: Nssetuncaughtexceptionhandler (uncaughtexceptionhandler);

Anychat Mobile Video development kits are for integration or software developers to use for mobile video-related product development and system integration. Development package to provide mobile phone audio and video capture, coding, compression, audio and video transmission functions, through the docking with the back-end server, priority Peer-to-peer Communication, the realization of mobile phone video is the transmission, mobile video live, cell phone video recording and mobile video calls.

Foreword: When doing iOS project today, need to be positioned to get the name of the current city. Baidu Maps SDK has this function, but in order to not rely on a third party, here I use iOS with the framework corelocation to achieve this requirement. IOS8 out, for positioning needs a little more processing, can be normal positioning, this will be at the end of the article to supplement, in the statement be

Html5+canvas mobile phone photo upload, found that the iOS mobile phone upload photos will be rotated counterclockwise 90 degrees, horizontal shot without this problem, the Android phone is not the problem. So the idea to solve this problem is to get to the orientation angle of the photo shoot, and to rotate the angle rotation of the iOS photos that are not sideways. Using Exif.js to read the photo inform

To prevent an application from consuming too much system resources, the Apple Engineer Gate that developed iOS designed a "watchdog" mechanism. In different scenarios, the watchdog monitors the performance of the application. If the runtime is exceeded by the scenario, the watchdog will force the end of the application process. In Crashlog, developers will see error codes such as 0x8badf00d. This is particularly true in the case of arc and the low ph

In order to have a good interactive experience, I believe that everyone in the treatment of ScrollView no data when the prompt page will use some third-party to customize, the most typical is the use of dznemptydataset. But it is not so good to write a bunch of code related to Dznemptydatasetdelegate,dznemptydatasetsource in every interface, and that's usually the way to avoid it. And Swift, in addition to object-oriented programming, can also be oriented toward protocol programming. Can you als

Addgesturerecognizer:imagetap]; [Self.view AddSubview:self.smallImageView]; } Notice that I've used two preset constants to set the size of a small image: the height and width of the screen, this will be based on the screen size of the phone to ensure that the picture is always centered, for these two constants, you can view my blog: iOS get screen width, device model, system version information OK now the small figure has been added to the

iOS constraint conflicts generally fall into two categories: Margin constraint conflicts or dimension collisions, which can often be modified by modifying the constraint precedence of one of the controls, using the content hugging/content Compression resistance, The prerequisite for use is to determine the size of its control, which is generally used after the AutoLayout is successfully constrained. To set the maximum priority, you can ensure that an

Introduction of SQLiteSQLite is a pure C implementation, so doomed it is a cross-platform tool, both under the Android and iOS can be used, but also can write common code, convenient for us to transplant. Of course, Android and iOS have encapsulated SQLite for developers to use, but this is not easy to transplant, the other is the efficiency of the package after how we do not know, so or the original ecolog

These two days in a calendar to remind the function, the use of local notification function, record the relevant knowledge as follows: 1, the definition and use of local notification: A local notification is an instance of Uilocalnotification, which has three main types of properties: Scheduled time, which is used to specify the date and time the iOS system sends notifications; Notification type, the notification type, including warning messages,

The UIWebView of iOS development is what this article is about, UIWebView is one of the most commonly used controls in the iOS SDK. is a built-in browser control that we can use to browse Web pages, open documents, and so on. In this article I will use this control to make a simple browser. The following figure: We create a window-based application program named: Uiwebviewdemo The UIWebView loadrequest

In iOS application development, in order to reduce the number of interactions with the server, speed up the user's response speed, the iOS device will generally add a caching mechanism. The purpose of using caching is to use the application to respond more quickly to user input, and to run the program efficiently. Sometimes we need to cache the data obtained by the remote Web server and reduce multiple requ
