Why a frame of a UIView is not updating in ViewDidLayoutSubviews?

早过忘川 提交于 2019-12-05 15:17:04
问题 I am trying to update the frame of a UIView which contains buttons and labels inside. I am trying to update it in viewDidLayoutSubviews (and I also tried in viewDidLoad , viewWillAppear , viewDidAppear ..). I want to change the y position (origin.y) of the view. The NSLogs says my original y position is 334, and after changing, it is 100. However, the position does not change in my view. I have already checked that the view is connected in the storyboard. What am I doing wrong? -(void

除了需要添加正常的Room runtime library外,还需要注解处理器,否则会报错 implementation "androidx.room:room-runtime:$rootProject.roomVersion" annotationProcessor "androidx.room:room-compiler:$rootProject.roomVersion" Steho的使用   chrome://inspect/#devices ;点击对应的app名称下面的inspect,如果打不开报404;需要翻墙(只需翻一次,然后退出翻墙软件就可以) implementation 'com.facebook.stetho:stetho:1.5.0' 来源: https://www.cnblogs.com/endian11/p/11929254.html

How do I adjust log4j levels at runtime?

北战南征 提交于 2019-12-05 14:50:32
问题 I have a simple web app running on Tomcat 5.5 with log4j for logging. Occasionally I need to push the logging down to DEBUG but most of the time I'm happy with INFO. I can change my config xml and restart the app but I would prefer to switch the log levels on the fly. Is there a standard technique for this? 回答1: Just use the programmatic API: logger.setLevel(Level.DEBUG) in your program when you need more verbose logging output, and logger.setLevel(Level.INFO) to make it less verbose again.

matplotlib get rid of max_open_warning output

问题 I wrote a script that calls functions from QIIME to build a bunch of plots among other things. Everything runs fine to completion, but matplotlib always throws the following feedback for every plot it creates (super annoying): /usr/local/lib/python2.7/dist-packages/matplotlib/pyplot.py:412: RuntimeWarning: More than 20 figures have been opened. Figures created through the pyplot interface ( matplotlib.pyplot.figure ) are retained until explicitly closed and may consume too much memory. (To

How does function overloading work at run-time, and why overload?

家住魔仙堡 提交于 2019-12-05 12:10:17
Let's say I have a class named ClothingStore. That class has 3 member functions, that point a visitor to the right department of the store. Member functions are ChildrenDept, MenDept and WomenDept, depending on whether the visitor is a child, a man or a woman. Function overloading can be used to make 3 functions that have same name, say, PointToDept, but take different input argument ( child, man, woman ). What is actually happening on run-time when program is executing ? My guess is that compiler adds switch statements to the program, to select the right member function. But that makes me

一、统计方法和字符串离散化 假设现在我们有一组从 2006 年 1000 部最流行的电影数据,我们想知道这些电影数据中的评分的平均分,导演的人数等信息,我们应该怎么获取?   数据来源: https://www.kaggle.com/damianpanek/sunday-eda/data import pandas as pd from matplotlib import pyplot as plt file_path = "./IMDB-Movie-Data.csv" df = pd.read_csv(file_path) print(df.info()) print(df.head()) #获取平均评分 print(df["Rating"].mean()) #获取导演的人数 print(len(set(df["Director"].tolist()))) #print(len(df["Director"].unique())) #获取演员的人数 temp_actors_list = df["Actors"].str.split(", ").tolist() actor_list = [i for j in temp_actors_list for i in j] actor_num = len(set(actor_list)) print(actor_num)

Determining if an Objective-C method is variadic during runtime

你离开我真会死。 提交于 2019-12-05 10:35:54
Is there a way to find out -- at runtime -- whether a given method is of variadic type? Something like method_getTypeEncoding() ; that won't tell me whether a method accepts variable number of arguments. Or is there maybe a trick to tell so? Robert's comment is correct. Consider: @interface Boogity @end @implementation Boogity - (void)methodWithOneIntArg:(int)a {;} - (void)variadicMethodWithIDSentinel:(id)a, ... {;} @end Running strings on the resulting binary produces (there was also the stock main() ): strings asdfasdfasdf Boogity methodWithOneIntArg: variadicMethodWithIDSentinel: v20@0:8i16
