এই পোস্টে আমাকে সাহায্য একটি অনেক !
আমি প্রস্তাবিত ক্রিয়াকলাপের সাথে ইউআইভিউএলার্টফরউস্যান্টসাইফিয়েবল কনট্রেন্টসকে প্রতীকী ব্রেকআপপয়েন্ট যুক্ত করেছি :
ওবজে-সি প্রকল্প
po [[UIWindow keyWindow] _autolayoutTrace]
সুইফ্ট প্রকল্প
expr -l objc++ -O -- [[UIWindow keyWindow] _autolayoutTrace]
এই ইঙ্গিতটির সাহায্যে লগটি আরও বিশদ আকার ধারণ করে এবং কোন দৃশ্যের সীমাবদ্ধতা ভঙ্গ হয়েছিল তা সনাক্ত করা আমার পক্ষে সহজ।

তারপরে আমি মৃত্যুদণ্ড থামিয়ে দিয়েছি এবং কমান্ডটি দিয়ে সমস্যাযুক্ত ভিউটির পটভূমির রঙ পরিবর্তন করেছি ( অবশ্যই আপনার অবজেক্টের0x7f88a8cc2050
মেমরি ঠিকানার পরিবর্তে ) ...
OBJ-সি
expr ((UIView *)0x7f88a8cc2050).backgroundColor = [UIColor redColor]
সুইফট 3.0
expr -l Swift -- import UIKit
expr -l Swift -- unsafeBitCast(0x7f88a8cc2050, to: UIView.self).backgroundColor = UIColor.red
... এবং ফলাফল এটি দুর্দান্ত ছিল!
স্বাভাবিকভাবেই সুন্দর! আশা করি এটা সাহায্য করবে.
