学习总结5

开始学习IOS已经五周了，从无到有，慢慢的学会了很多东西。这周的学习比起以往有更多的收获，学习做了一个模仿QQ音乐的程序，从中知道了什么是架构以及架构的重要性。 很多东西都不会，但是通过做一个稍微完整的项目，可以开始学会资源整合，学习过的知识的综合应用。下面附上作业的代码，虽然还有很多需要改进的地方，但已经是一个质的跨越。 学习就是一个积累的过程，不会的东西越多，学到的东西也就越多。有一个好的学习环境至关重要。有环境的保护，加上自己的努力，一定能迈进大神的行列。 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
