Overview

ODUIThreadGuard

ODUIThreadGuard is a guard to help check if you make UI changes not in main thread.

As Xcode 9 embedded this function into Xcode, there is no reason to maintain this project in the feature, Happy Coding.

Carthage compatible CocoaPods Support Swift Version License MIT

ODUIThreadGuard is a guard to help check if you make UI changes not in main thread. Highly recommend you add this file to your project as early as possible.

ScreenShot

Features

  • Passive implementation
  • Throw an assertion if setNeedsDisplay, setNeedsLayout, or setNeedsDisplayInRect: is called for instantiation of any UIView
  • Get the thread stack to help you locate where you make the mistake

Usage

No matter which way you use ODUIThreadGuard, no need to import any files, it is a extension of UIView, so it will work automatically.

CocoaPods

You can use CocoaPods to install ODUIThreadGuard by adding it to your Podfile:

platform :ios, '8.0'
use_frameworks!
pod 'ODUIThreadGuard'

Then drop ODUIThreadGuard.swift into your porject.

Carthage

Create a Cartfile that lists the framework and run carthage update. Follow the instructions to add $(SRCROOT)/Carthage/Build/iOS/YourLibrary.framework to an iOS project.

github "olddonkey/ODUIThreadGuard"

Manually

  1. Download and drop ODUIThreadGuard.swift in your project.
  2. Congratulations!

You can change the pre compile flag to change the setting, in default, this only runs in DEBUG mode, so won't affect users in Release.

Requirements

  • iOS 8.0+
  • Swift 3

The main development of ODUIThreadGuard is based on Swift 3.

  • Very confused about usage

    Very confused about usage

    The README says there's "no need to import any files, it is a extension of UIView, so it will work automatically" but then in a later paragraph it seems you need to drag a file into your project to use it? Unclear how to get this working. Dragging and dropping a file into one's project sort of nullifies the point of using Cocoapods. :)

    Possible naming problem

    Hi, nice library.

    Not really sure if this is a problem, that's why I did not do the pull request.

    But, shouldn't your own swizzled methods, call the original implementations (and not itself) ?

    func guardSetNeedsLayout() {
        checkThread()
        guardSetNeedsLayout() <----
    }

    func guardSetNeedsDisplay() {
        checkThread()
        guardSetNeedsDisplay() <----
    }

    func guardSetNeedsDisplayInRect(_ rect: CGRect) {
        checkThread()
        guardSetNeedsDisplayInRect(rect) <-----
    }

    /// It is better to use a debug flag here for not add this extension to Release build. (You don't want user see App crash) 这句注释有点歧义，不应该在Release版本打开，为什么这样？

    我的理解是 在Debug版本去掉，Release打开，把问题尽量暴露在测试开发阶段，上线之后打开，多一层保护，防止异常。

    Hello, I tried both cocoa pods and manually adding the .swift file but I am still not getting the logs. I tried exactly the same thing as you have in demo but no luck, any idea what could be wrong ?
