iOS: Easy cast with _ObjectiveCBridgeable
Swift is out there for about a year and it’s a great programming language. I think that almost every iOS/OSX developer out there has already written couple of things in Swift (if you haven’t, go ahead and try, you won’t regret it, I promise). Although, we have many years of libs and frameworks built...Post: iOS: Easy cast with _ObjectiveCBridgeable | 12:07 Jul 12, 2016
iOS: UIAlertController text alignment
Custom text alignment of UIAlertController: let controller = UIAlertController(title: t, message: informative, preferredStyle: type) let paragraphStyle = NSMutableParagraphStyle() paragraphStyle.alignment = alignment paragraphStyle.lineBreakMode = lineBreakMode let messageText = NSMutableAttribute...Post: iOS: UIAlertController text alignment | 12:07 Jul 10, 2016
Difference between nullable, __nullable and _Nullable in Objective-C
From the Swift blog: This feature was first released in Xcode 6.3 with the keywords __nullable and __nonnull. Due to potential conflicts with third-party libraries, we’ve changed them in Xcode 7 to the _Nullable and _Nonnull you see here. However, for compatibility with Xcode 6.3 we’ve predefined m...Post: Difference between nullable, __nullable and _Nullable in Objective-C | 12:07 Jul 07, 2016

OS X: Menu Bar Extra is invisible in macOS Dark Mode
周末提交的 APP 又被秒拒, 理由很简单, “Menu Bar Extra is invisible in macOS Dark Mode”, 菜单栏图标在黑色模式中看不到。 由于是第一次用黑白色的图标, 提交之前完全没有考虑到这个问题, 怎么解决呢? 其实很简单。 首先我想到的第一件事是监听, 先试了 NSScreenColorSpaceDidChangeNotification 不起作用, 后来找到了另一个通知: [[NSDistributedNotificationCenter defaultCenter] addObserver:self selector:@selector(upd...Post: OS X: Menu Bar Extra is invisible in macOS Dark Mode | 12:06 Jun 28, 2016
CentOS: Install Clang
本文主要关于在 CentOS 中安装 Clang 的相关步骤。 (以 CentOS 7 为例) 安装 libstdc++ 如果你正在使用 CentOS 7 及以上的版本，请直接跳过此步骤。 wget https://people.centos.org/tru/devtools-2/devtools-2.repo -O /etc/yum.repos.d/devtools-2.repo yum install devtoolset-2-gcc devtoolset-2-binutils devtoolset-2-gcc-c++ ln -s /opt/rh/devtoolset-2/root...Post: CentOS: Install Clang | 12:06 Jun 24, 2016
Ubuntu: Using Swift
本文主要关于在 Ubuntu 中安装和使用 Swift 的相关步骤。 (以 Ubuntu 15.10 为例) 下载 Swift 在 Swift.org 找到并下载对应的 Swift 版本。 解压 Swift $ cd Swift压缩包所在目录的路径 $ tar -xf Swift压缩包文件名.tar.gz $ mv Swift解压后的文件夹名 /swift (最后一句 mv 是为了方便操作，可以省略，/swift 也可以是其它路径) 举个例子: $ cd /home/meniny/Desktop/swift-2.2.1-RELEASE-ubuntu15.10.tar.gz $ tar -x...Post: Ubuntu: Using Swift | 12:06 Jun 24, 2016
OS X: csrutil
El Capitan 加入了 Rootless 机制, 不再能够随心所欲的读写很多路径真是很难过。 Rootless 机制将成为对抗恶意程序的最后防线 要关闭 Rootless, 需要进入恢复系统。开机时按住 option 选择恢复磁盘 (或在开机时按住 command + R), 在菜单中找到并打开 Terminal。 csrutil disable 然后重启即可。 如果要恢复默认: csrutil enable csrutil csrutil enable [--without kext | fs | debug | dtrace | nvram][--no-internal]...Post: OS X: csrutil | 12:06 Jun 01, 2016

max-height: x% doesn't work on Chrome
Some times using percentages for fluidity in layouts is tricky because you have to deal with containers and border-type things. Look in to using viewport units and learn some thing about it on css-tricks and caniuse will show you how well it's supported. Essentially you can say: <div style="...Post: max-height: x% doesn't work on Chrome | 12:05 May 13, 2016
Swift: Optional Protocol Methods Without @objc
Objective-C 协议 (protocol) 在 Swift 中是一个特殊的存在, 当你使用 @objc 标记一个协议, LLVM 会生成一系列额外内容: 一个 isa 指针 运行时模块, 例如 __objc_imageinfo、__objc_classref 等 Swift 协议并不支持可选 (optional), 除非我们将协议导出到 Objective-C, 因为这时它们已经变成了 Objective-C 协议。 此外, 这些协议也不能用于扩展 (extension)、枚举 (enum) 和结构体 (struct), 作用十分有限, 如果你在 Linux 环境下使用 Swift...Post: Swift: Optional Protocol Methods Without @objc | 12:05 May 12, 2016
Cocoa: Change Cursor
The way to change the cursor when it's over an NSButton: First, you should subclass NSButton first, then add the code below: @property (strong) NSCursor *cursor; - (void)resetCursorRects { if (self.cursor) { [self addCursorRect:[self bounds] cursor: self.cursor]; } else { ...Post: Cocoa: Change Cursor | 12:05 May 10, 2016
