我一直在看maxmethod在Ruby的Enumerable混合(v2.4.1)。这是一个相当简单的方法,但是当存在重复项时它如何排序项目有点令人困惑。例如:x=[1,2,3,4,5,6,7,8,9]x.max{|a,b|a%2b%2}=>110.times{|y|px.max(y){|a,b|a%2b%2}}[][1][1,7]#whyis7thenextelementafter1?[3,1,5]#whynomore7?[7,3,1,5]#7isnowfirst[9,7,3,1,5][9,7,3,1,5,6][9,7,3,1,5,4,6][9,7,3,1,5,2,4,6][9,7,5
几天来,我一直在四处寻找,试图弄清楚为什么我的post_installHook没有产生我期望的输出。这是我的Podfile:source'https://github.com/CocoaPods/Specs.git'target"SCCommon"doplatform:ios,"6.0"pod'AFNetworking','~>1.2.1'pod'Mantle','~>1.3'pod'PubNub','3.5.5'endtarget"SCCommon-TestHarness"doplatform:ios,"6.0"#inhibit_all_warnings!pod'SCCommon',
