一、介绍
前面介绍了VC的生命周期,闲着没事也来捋一捋View的生命周期,简单用两个类型的View来监测。一个View纯代码创建,另一个View使用Xib创建。
二 、代码
MyCodeView:
// // MyCodeView.m // 生命周期 // // Created by 夏远全 on 2019/11/3. // Copyright © 2019 Beijing Huayue Education Technology Co., Ltd. All rights reserved. // #import "MyCodeView.h" @implementation MyCodeView - (instancetype)initWithFrame:(CGRect)frame { NSLog(@"myCodeView-------%s",__func__); return [super initWithFrame:frame]; } - (nullable instancetype)initWithCoder:(NSCoder *)coder { NSLog(@"myCodeView-------%s",__func__); return [super initWithCoder:coder]; } -(void)awakeFromNib { NSLog(@"myCodeView-------%s",__func__); return [super awakeFromNib]; } -(instancetype)init { NSLog(@"myCodeView-------%s",__func__); return [super init]; } - (void)willMoveToSuperview:(nullable UIView *)newSuperview { NSLog(@"myCodeView-------%s",__func__); [super willMoveToSuperview:newSuperview]; } - (void)didMoveToSuperview { NSLog(@"myCodeView-------%s",__func__); [super didMoveToSuperview]; } - (void)willMoveToWindow:(nullable UIWindow *)newWindow { NSLog(@"myCodeView-------%s",__func__); [super willMoveToWindow:newWindow]; } - (void)didMoveToWindow { NSLog(@"myCodeView-------%s",__func__); [super didMoveToWindow]; } - (void)layoutSubviews { NSLog(@"myCodeView-------%s",__func__); [super layoutSubviews]; } - (void)drawRect:(CGRect)rect { NSLog(@"myCodeView-------%s",__func__); [super drawRect:rect]; } -(void)dealloc { NSLog(@"myCodeView-------%s",__func__); } @end
MyXibView:
// // MyXibView.m // 生命周期 // // Created by 夏远全 on 2019/11/3. // #import "MyXibView.h" @implementation MyXibView - (instancetype)initWithFrame:(CGRect)frame { NSLog(@"myXibView-------%s",__func__); return [super initWithFrame:frame]; } - (nullable instancetype)initWithCoder:(NSCoder *)coder { NSLog(@"myXibView-------%s",__func__); return [super initWithCoder:coder]; } -(void)awakeFromNib { NSLog(@"myXibView-------%s",__func__); return [super awakeFromNib]; } -(instancetype)init { NSLog(@"myXibView-------%s",__func__); return [super init]; } - (void)willMoveToSuperview:(nullable UIView *)newSuperview { NSLog(@"myXibView-------%s",__func__); [super willMoveToSuperview:newSuperview]; } - (void)didMoveToSuperview { NSLog(@"myXibView-------%s",__func__); [super didMoveToSuperview]; } - (void)willMoveToWindow:(nullable UIWindow *)newWindow { NSLog(@"myXibView-------%s",__func__); [super willMoveToWindow:newWindow]; } - (void)didMoveToWindow { NSLog(@"myXibView-------%s",__func__); [super didMoveToWindow]; } - (void)layoutSubviews { NSLog(@"myXibView-------%s",__func__); [super layoutSubviews]; } - (void)drawRect:(CGRect)rect { NSLog(@"myXibView-------%s",__func__); [super drawRect:rect]; } -(void)dealloc { NSLog(@"myCodeView-------%s",__func__); } @end
三 、测试

[self.view addSubview:_codeView]; } -(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event { NSLog(@"移除过程:"); [self.codeView removeFromSuperview]; [self setCodeView:nil]; }
