【iOS-性能优化一】卡顿产生的原因 -
上面self.arr1 = array;
不是应该等于 NSMutableArray *arr1 = [array copy]吗，//( NSMutableArray *arr1 == self. arr1是可变的数组)
那arr1 -> self.arr1 不是应该是个可变数组吗，为什么这里不能调可变数组的api?
不太理解为什么NSMutableArray用copy修饰会crash?

So there is no callback on the development account. Recently, we have encountered new problems. 2. When the 13.1.3 system installs the app, when pulling up the authorization page and returning, it will directly report an error as follows:
Error Domain=TWTRNetworkingErrorDomain Code=-1011 \"Request failed: forbidden (403)\" UserInfo={NSLocalizedFailureReason=Twitter API error : <?xml version=\"1.0\" encoding=\"UTF-8\"?><errors><error code=\"415\">Callback URL not approved for this client application. Approved callback URLs can be adjusted in your application settings</error></errors> (code (null)), TWTRNetworkingStatusCode=403, NSErrorFailingURLKey=https://api.twitter.com/oauth/request_token, NSLocalizedDescription=Request failed: forbidden (403)}" ,
But the iPhone with the 12.4 system is good. After checking the relevant information, it is said that the callback address is not set, so why the 12.4 system mobile phone is normal.

设置callback，确实好了。但是发现设置了这个url 如果有安装过app的话，会二次唤起授权页（先唤起Twitter app，然后回到自己app时，还会唤起Twitter网页授权页）。这个怎么解决的？
