iOS 纯代码自定义UITableview，对cell里有tex
本人刚接触纯代码布局，所以请大神不要嘲笑，写个文章记录一下,文章里用到了一个把图片设置成圆形的分类，如有需要请留言！
文章里对text文本的处理，通用于collectionview。欢迎大家一起交流，学习。

步骤：
1.自定义tableviewCell类
2.模型类
3. 在一个UIViewController里添加一个uitableview
第一步：自定义tableviewCell类
tableviewCell.h里：
#import@class PersonalInformationEditorModel;
@interface PersonalInformationEditorCell : UITableViewCell
/** model */
@property(nonatomic,strong)PersonalInformationEditorModel *model;
@property(nonatomic,strong) UILabel *labelName;
/** wenben */
@property(nonatomic,strong)UITextField *attribute;
@end
tableviewCell.m里：
#import "PersonalInformationEditorCell.h"
#import "PersonalInformationEditorModel.h"
@interface PersonalInformationEditorCell ()
@end
@implementation PersonalInformationEditorCell
- (void)awakeFromNib {
[super awakeFromNib];
}
//通过纯代码的方式创建此类实例 会调用该方法 在此方法中，添加子控件
- (instancetype)initWithFrame:(CGRect)frame{
if(self = [super initWithFrame:frame]){
//选中cell的图片
UILabel *label = [[UILabel alloc]init];
[self addSubview:label];
self.labelName = label;
}
return self;
}
-(instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
//创建自定义的视图
[self creatView];
}
return self;
}
#pragma mark 设置子控件
- (void)creatView{
[self addSubview:self.labelName];
[self.labelName mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(20);
make.left.equalTo(20);
}];
[self addSubview:self.attribute];
[self.attribute mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(20);
make.right.equalTo(-20);
make.width.equalTo(200);
}];
}
#pragma maik 懒加载
-(UILabel *)labelName{
if (_labelName == nil) {
_labelName = [[UILabel alloc]init];
}
return _labelName;
}
-(UITextField *)attribute{
if (_attribute == nil) {
_attribute = [[UITextField alloc]init];
_attribute.borderStyle = UITextBorderStyleNone;
_attribute.placeholder = @"请输入要修改的内容";
_attribute.clearButtonMode = UITextFieldViewModeWhileEditing;
_attribute.textAlignment = UITextAlignmentRight;
_attribute.keyboardType = UIKeyboardTypeDefault;
_attribute.returnKeyType =UIReturnKeyDone;
}
return _attribute;
}
//设置子控件的内容
-(void)setModel:(PersonalInformationEditorModel *)model{
_model = model;
[self.labelName setText:model.name] ;
[self.attribute setText:model.attribute];
}
@end
第二步：模型类
模型类.h里：
#import@interface PersonalInformationEditorModel : NSObject
//名称
@property(nonatomic,copy)NSString *name;
//属性
@property(nonatomic,copy)NSString *attribute;
//快速创建实例
+ (instancetype)appWithDict:(NSDictionary *)dict;
@end
模型类l.m里：
#import "PersonalInformationEditorModel.h"
@implementation PersonalInformationEditorModel
+ (instancetype)appWithDict:(NSDictionary *)dict{
//这样写会通用 可以把这个 作为代码块了
id obj = [[self alloc] init];
[obj setValuesForKeysWithDictionary:dict];
return obj;
}
@end
第三步：在一个UIViewController里添加一个UITableview
UITableview.h里没有代码，所以直接.m ------UITableview.m里：
#import "PersonalInformationEditorVC.h"#import "UIImage+BSExtension.h"#import "PersonalInformationEditorCell.h"#import "PersonalInformationEditorModel.h"static NSString *ID = @"PersonalInformationEditorCell";@interface PersonalInformationEditorVC ()/** tableivew */
@property(nonatomic,strong)UITableView *tableView;
/** 数组 */
@property(nonatomic,strong)NSMutableArray *models;
@end
@implementation PersonalInformationEditorVC
- (void)viewDidLoad {
[super viewDidLoad];
[self setupUI];
[self setupNavigation];
[self setupTableView];
[self setupKeyFrame];
self.view.backgroundColor = [UIColor whiteColor];
}
- (void)setupUI {
//顶部头像view
UIView *topView = [[UIView alloc]init];
[self.view addSubview:topView];
// topView.backgroundColor = [UIColor orangeColor];
[topView mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.left.right.equalTo(0);
make.top.height.equalTo(200);
}];
//头像
UIImageView *headImage = [[UIImageView alloc]initWithImage:[UIImage circleImage:@"user2"]];
[topView addSubview:headImage];
[headImage mas_makeConstraints:^(MASConstraintMaker *make) {
make.centerX.equalTo(topView.centerX);
make.size.equalTo(CGSizeMake(100, 100));
make.top.equalTo(50);
}];
//名字
UILabel *nameLable = [[UILabel alloc]init];
nameLable.text = @"王宝强";
[topView addSubview:nameLable];
[nameLable mas_makeConstraints:^(MASConstraintMaker *make) {
make.centerX.equalTo(topView.centerX);
make.top.equalTo(headImage.bottom).offset(20);
}];
//tableview
[self.view addSubview:self.tableView];
[self.tableView mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(topView.bottom);
make.left.right.equalTo(0);
make.height.equalTo(self.view.height).offset(-200);
}];
}
-(void)setupKeyFrame{
//新增监听，当键盘出现
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(hotKeyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
//新增监听，当键盘退出
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(hotKeyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
UITapGestureRecognizer *topGestureRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(keyboardHide:)];
//设置成NO表示当前控件响应后会传播到其他控件上，默认yes
topGestureRecognizer.cancelsTouchesInView = NO;
//讲触摸事件添加到当前view
[self.view addGestureRecognizer:topGestureRecognizer];
}
- (void)setupNavigation {
self.title = @"个人信息编辑";
self.navigationController.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName : [CCTools stringToColor:@"#333333"]};
}
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:NO];
}
-(void)setupTableView{
//注册cell
[self.tableView registerClass:[PersonalInformationEditorCell class] forCellReuseIdentifier:ID];
}
#pragma mark - Table view data source
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return self.models.count;
}
//设置单元格的高度
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPat{
//这里设置cell的高度
return 60;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
PersonalInformationEditorCell *cell = [tableView dequeueReusableCellWithIdentifier:ID];
//给cell设置数据
cell.model = self.models[indexPath.row];
//处理键盘
[cell.attribute addTarget:self action:@selector(messageFiedClick:) forControlEvents:UIControlEventEditingChanged];
cell.attribute.delegate = self;
return cell;
}
#pragma -mark 代码方法
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
//取消选中 点击之后手放开就选中效果消失再执行下面的代码
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
#pragma mark -监听文本输入值
-(void)messageFiedClick:(UITextField *)textfield{
DLog(@"监听文本输入值");
}
#pragma mark - 键盘处理 回收键盘
- (void)keyboardHide:(UITapGestureRecognizer *)tap{
DLog(@"页面停止编辑");
[self.view endEditing:YES]; //页面停止编辑
}
#pragma mark 键盘出现
- (void)hotKeyboardWillShow:(NSNotification *)aNotification{
DLog(@" 键盘出现");
//取得键盘最后得frame
CGRect keyBoardRect=[aNotification.userInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue];
//获取键盘高度
// CGFloat height = keyBoardRect.size.height;
[UIView animateWithDuration:0.2 animations:^{
//修改的view的属性放在这里block中
self.tableView.contentInset = UIEdgeInsetsMake(0, 0, keyBoardRect.size.height, 0);
} completion:^(BOOL finished) {
}];
}
#pragma mark 键盘消失
- (void)hotKeyboardWillHide:(NSNotification *)aNotification{
DLog(@" 键盘消失");
//收键盘的时候按钮回去
[UIView animateWithDuration:0.2 animations:^{
//修改的view的属性放在这里block中
self.tableView.contentInset =UIEdgeInsetsZero;
} completion:^(BOOL finished) {
}];
}
#pragma mark - 完成 点击事件
- (BOOL)textFieldShouldReturn:(UITextView *)textField{
[textField resignFirstResponder];
return YES;
}
-(void)dealloc{
[[NSNotificationCenter defaultCenter]removeObserver:self];
}
#pragma mark -懒加载
-(NSMutableArray *)models{
if (_models == nil) {
//获得app.plist的路径
NSString *path = [[NSBundle mainBundle] pathForResource:@"SetPersonalInformationEditor" ofType:@"plist"];
//加载app.plist中的字典为数组
NSArray *arr = [NSArray arrayWithContentsOfFile:path];
NSMutableArray *array = [NSMutableArray array];
//字典转模型
for(NSDictionary *dict in arr){
PersonalInformationEditorModel *model = [PersonalInformationEditorModel appWithDict:dict];
[array addObject:model];
}
_models = array;
}
return _models;
}
-(UITableView *)tableView{
if (_tableView == nil) {
_tableView = [[UITableView alloc]init];
_tableView.delegate = self;
_tableView.dataSource = self;
self.tableView.tableFooterView = [[UIView alloc] init];//隐藏多余的分割线
}
return _tableView;
}
