This article mainly introduces the classification of tableView in iOS, which is very detailed and has a certain reference value. Friends who are interested must read it!

Roughly divided, a uitableview needs several methods to implement, create a tableivew, customize a cell, a cell model, a cell sub-control size, complex can be added to inherit tableview method 1 is 3 or 4, or 5.

# import "ViewController.h"

@ interface XXTableiewCell: UITableViewCell

@ end

Const float XXTableiewCell_fontSize = 12

@ interface XXTableiewCell ()

@ property (strong, nonatomic) UILabel * titleLabel

@ property (strong, nonatomic) UILabel * showTilleLable

@ end

@ implementation XXTableiewCell

+ (instancetype) cellWithTableView: (UITableView *) tableView {

Static NSString * cellID = @ "cellId"

XXTableiewCell * cell = [[XXTableiewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID]

Return cell

}

-(id) initWithStyle: (UITableViewCellStyle) style reuseIdentifier: (NSString *) reuseIdentifier {

Self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]

If (self) {

[self setViewUI]

}

Return self

}

-(void) setViewUI {

_ titleLabel = [[UILabel alloc] init]

_ titleLabel.font = [UIFont systemFontOfSize:XXTableiewCell_fontSize]

_ titleLabel.textColor = [UIColor grayColor]

_ titleLabel.textAlignment = NSTextAlignmentLeft

_ titleLabel.backgroundColor = [UIColor clearColor]

[self.contentView addSubview:_titleLabel]

_ showTilleLable = [[UILabel alloc] init]

_ showTilleLable.font = [UIFont systemFontOfSize:XXTableiewCell_fontSize]

_ showTilleLable.textColor = [UIColor grayColor]

_ showTilleLable.textAlignment = NSTextAlignmentLeft

_ showTilleLable.backgroundColor = [UIColor clearColor]

[self.contentView addSubview:_showTilleLable]

}

-(void) layoutSubviews {

[super layoutSubviews]

_ titleLabel.frame = CGRectMake (10,0, self.contentView.frame.size.width-20, 20)

_ showTilleLable.frame = CGRectMake (_ titleLabel.frame.origin.x, _ titleLabel.frame.size.height + _ titleLabel.frame.origin.y + 5, _ titleLabel.frame.size.width, _ titleLabel.frame.size.height)

}

@ end

@ interface ViewController ()

@ property (strong,nonatomic) NSMutableArray * resultArry

@ end

@ implementation ViewController

-(void) viewDidLoad {

[super viewDidLoad]

_ resultArry = [NSMutableArray arrayWithArray: [UIFont familyNames]]

UITableView * tableView = [[UITableView alloc] initWithFrame:self.view.frame style:UITableViewStylePlain]

TableView.dataSource = self

TableView.delegate = self

[self setExtraCellLineHidden:tableView]

[self.view addSubview:tableView]

}

/ / hide excess cell

-(void) setExtraCellLineHidden: (UITableView *) tableView

{

UIView * view = [UIView new]

View.backgroundColor = [UIColor clearColor]

[tableView setTableFooterView:view]

}

-(NSInteger) tableView: (UITableView *) tableView numberOfRowsInSection: (NSInteger) section

{

Return _ resultArry.count

}

-(UITableViewCell *) tableView: (UITableView *) tableView cellForRowAtIndexPath: (NSIndexPath *) indexPath

{

XXTableiewCell * cell = [XXTableiewCell cellWithTableView:tableView]

Cell.titleLabel.text = [NSString stringWithFormat:@ "% ld", (NSInteger) indexPath.row + 1]

Cell.showTilleLable.text = [NSString stringWithFormat:@ "% @", _ resultArry [indexPath.row]]

Return cell

}

# pragma mark- sets the height of each group

-(CGFloat) tableView: (UITableView *) tableView heightForRowAtIndexPath: (NSIndexPath *) indexPath

{

Return 50

}

# how to select pragma mark settings

-(void) tableView: (UITableView *) tableView didSelectRowAtIndexPath: (NSIndexPath *) indexPath {

NSLog (@ "% ld", indexPath.row + 1)

}
