ios开发系列 ---- ui (自定义tableview)。本章实现效果:
![customtableview](http://www.lhsxpumps.com/_images3/10qianwan/20181114/b_0_201811142224426418.jpg "\")
我们使用mvc架构来实现自定义tableview，具体的mvc介绍请自行百度，在本章中不作为主要内容讲解。
model层：
datasource.h
#import @interface datasource : nsobject + (nsarray *)getuserinfo; @end
datasource.m
我要评论
#import "datasource.h"
@implementation datasource
+ (nsarray *)getuserinfo {
nsstring * path = [[nsbundle mainbundle] pathforresource:@"users" oftype:@"plist"];
nsarray * arrayreturn = [nsarray arraywithcontentsoffile:path];
return arrayreturn;
}
@end
view层:
customtableviewcell.h
#import @interface customtableviewcell : uitableviewcell @property (nonatomic, strong) uilabel * labelname;//姓名 @property (nonatomic, strong) uilabel * labelnum; //手机号 @end
customtableviewcell.m
#import "customtableviewcell.h"
@implementation customtableviewcell
//重写初始化方法:将控件添加到单元格上,如果将子视图控件添加到cell上 借助contenview视图,这样的话cell上子视图会随着cell的变化而变化
- (instancetype)initwithstyle:(uitableviewcellstyle)style reuseidentifier:(nsstring *)reuseidentifier {
if (self = [super initwithstyle:style reuseidentifier:reuseidentifier]) {
self.labelname = [[uilabel alloc] initwithframe:cgrectmake(100, 0, self.bounds.size.width-200, 40)];
self.labelname.textcolor = [uicolor cyancolor];
self.labelname.textalignment = nstextalignmentcenter;
[self.contentview addsubview:self.labelname];
self.labelnum = [[uilabel alloc] initwithframe:cgrectmake(100, 40, self.bounds.size.width-200, 40)];
self.labelnum.textcolor = [uicolor greencolor];
self.labelnum.textalignment = nstextalignmentcenter;
[self.contentview addsubview:self.labelnum];
}
return self;
}
- (void)awakefromnib {
[super awakefromnib];
}
- (void)setselected:(bool)selected animated:(bool)animated {
[super setselected:selected animated:animated];
}
@end
viewcontroller层:
viewcontroller.m
#import "viewcontroller.h"
#import "datasource.h"
#import "customtableviewcell.h"
#import "twoviewcontroller.h"
@interface viewcontroller ()<
uitableviewdatasource,
uitableviewdelegate>
@property (nonatomic, strong) nsmutablearray *arrayds;
@property (nonatomic, strong) uitableview *tableview;
@end
@implementation viewcontroller
- (void)viewdidload {
[super viewdidload];
[self setupdatas];
[self setupsubviews];
}
- (void)setupdatas {
//从model层拿到数据
nsarray * array = [datasource getuserinfo];
//把拿到的数据给我们的数据源
self.arrayds = [[nsmutablearray alloc] initwitharray:array];
self.navigationitem.title = @"自定义单元格";
}
- (void)setupsubviews {
self.automaticallyadjustsscrollviewinsets = no;
self.tableview = [[uitableview alloc] initwithframe:cgrectmake(0, 64, self.view.bounds.size.width, self.view.bounds.size.height-64) style:uitableviewstyleplain];
self.tableview.delegate = self;
self.tableview.datasource = self;
[self.view addsubview:self.tableview];
uiview *view = [[uiview alloc] initwithframe:cgrectmake(0, self.view.bounds.size.height-50, self.view.bounds.size.width, 50)];
view.backgroundcolor = [uicolor redcolor];
[self.view insertsubview:view abovesubview:self.tableview];
}
#pragma mark - uitableviewdatasource
- (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section {
return self.arrayds.count;
}
- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {
static nsstring * str = nil;
if ([[[self.arrayds objectatindex:indexpath.row] objectforkey:@"phonenum"] hasprefix:@"100"]) {
str = @"customcell";
customtableviewcell * cell = [tableview dequeuereusablecellwithidentifier:str];
if (cell == nil) {
cell = [[customtableviewcell alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:str];
}
cell.labelname.text = [[self.arrayds objectatindex:indexpath.row] objectforkey:@"personname"];
cell.labelnum.text = [[self.arrayds objectatindex:indexpath.row] objectforkey:@"phonenum"];
return cell;
} else {
str = @"systemcell";
uitableviewcell * cell = [tableview dequeuereusablecellwithidentifier:str];
if (cell == nil) {
cell = [[uitableviewcell alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:str];
}
cell.textlabel.text = [[self.arrayds objectatindex:indexpath.row] objectforkey:@"phonenum"];
return cell;
}
}
- (void)viewwillappear:(bool)animated {
[super viewwillappear:animated];
[self.tableview reloaddata];
}
- (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath {
twoviewcontroller *twovc = [[twoviewcontroller alloc] init];
[self.navigationcontroller pushviewcontroller:twovc animated:yes];
}
- (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath {
return 100;
}
