Cocoa Key Equivalent in Menu is not working

由 Deadly 提交于 2021-02-10 05:51:51
问题 I have created a NSStatusItem and I have assigned two key equivalents within interface builder (Xcode 4.0). These are for the preference menu cmd-, and the quit option cmd-q. Both of these will work when the Menu is highlighted/open but will not work otherwise even if the application is the foremost. Any ideas on why this is happening or how I can change this? 回答1: The operating system passes key events that it doesn't handle to the front application, which compares them to any key

Xcode Storyboard - Where to set UITableViewCell height

由 瘦欲@ 提交于 2021-02-10 05:48:05
问题 I am using Xcode 7 and I am trying to set the height of a UITableViewCell in the storyboard settings to have a different cell height for different devices (eg. normal and compact x regular). I cannot find a place for these settings. Is this only possible by doing it programmatically? 回答1: Click on Table View after that click on Size Inspector and adjust your cell row height here - Add this below code in your controller class viewDidLoad tableView.estimatedRowHeight = 100.0 // Adjust Primary

Proper transition between SpriteKit Animations

问题 I have an idle player animation and I want to do a smooth transition between some animations. The idle animation is the default one and from that transition I want to be able to switch to another state(let's say fight) and then back to idle. The code for the idle character animation is currently like : self.addChild(playerAnimation) playerAnimation.runAction(SKAction.repeatActionForever( SKAction.animateWithTextures(playerAnimationManager.idleManAnimation.textureArray, timePerFrame: 0.1)))

iOS性能优化之Leaks动态分析

#iOS性能优化之Leaks动态分析 Instruments-Leaks有很多跟踪模块可以动态分析和跟踪内存, CPU 和文件系统（因为是动态分析 所以必须运行才能打开）。 ##具体使用 在XCode Open菜单下，点击Leaks 对App进行动态分析（快捷键CMD + i） 或者直接在工程中选择调试导航 在右侧点击Profile in instruments 检测图： Separate by Thread：按线程分开做分析，这样更容易揪出那些吃资源的问题线程。特别是对于主线程，它要处理和渲染所有的接口数据，一旦受到阻塞，程序必然卡顿或停止响应。 Invert Call Tree：反向输出调用树。把调用层级最深的方法显示在最上面，更容易找到最耗时的操作。 Hide Missing Symbols：隐藏缺失符号。如果dSYM文件或其他系统架构缺失，列表中会出现很多奇怪的十六进制的数值，用此选项把这些干扰元素屏蔽掉，让列表回归清爽。 Hide System Libraries：隐藏系统库文件。过滤掉各种系统调用，只显示自己的代码调用。 Flattern Recursion：拼合递归。将同一递归函数产生的多条堆栈（因为递归函数会调用自己）合并为一条。 双击就可以定位到具体的代码了。 更多参考： ios Instruments之Allocations iOS
