IOS学习（九）UITabView使用及几种常见的创建方式

1. 纯代码创建

- (void)viewdidload {
    [super viewdidload];
    // do any additional setup after loading the view.
    self.view.backgroundcolor = [uicolor graycolor];
    
    //style:uitableviewstylegrouped 分组
    //style:uitableviewstyleplain 当组名称滑动到顶部时，将固定在顶部位置
    uitableview *tabview = [[uitableview alloc] initwithframe:self.view.frame style:uitableviewstyleplain];
    tabview.backgroundcolor = [uicolor yellowcolor];
    tabview.datasource = self;
    [self.view addsubview:tabview];
}

- (nsinteger)numberofsectionsintableview:(uitableview *)tableview{
    return 5;
}

- (nsstring *)tableview:(uitableview *)tableview titleforheaderinsection:(nsinteger)section{
    return [nsstring stringwithformat:@"分组%zd", section];
}
- (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section{
    return 6;
}


- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath{
    
    uitableviewcell *cell = [[uitableviewcell alloc] initwithframe:cgrectmake(0, 0, cgrectgetwidth(self.view.bounds), 50)];
    
    cell.textlabel.text = [nsstring stringwithformat:@"hello%zd", indexpath.row];
    return cell;
}

 

2. 创建viewcontroller时，同时创建.xlb文件，再把uitabview拖拽到.xlb文件中

 

#import "secondviewcontroller.h"

@interface secondviewcontroller ()
@property (weak, nonatomic) iboutlet uitableview *tabview;

@end

@implementation secondviewcontroller

- (void)viewdidload {
    [super viewdidload];
    // do any additional setup after loading the view from its nib.
    
    self.tabview.backgroundcolor = [uicolor greencolor];
}

 

3.自定义tabview，需创建一个。xlb文件

#import 

@interface customtabview : uitableview

+ (instancetype) tableviewwithdatasource:(id) datasource;
@end

#import "customtabview.h"

@implementation customtabview


+ (instancetype)tableviewwithdatasource:(id)datasource{
    customtabview *customtabview = [[[nsbundle mainbundle] loadnibnamed:@"customtabvew" owner:self options:nil] lastobject ];
    
    customtabview.datasource = datasource;
    return customtabview;
}

#import "thirdviewcontroller.h"
#import "customtabview.h"

@interface thirdviewcontroller ()

@end

@implementation thirdviewcontroller

- (void)viewdidload {
    [super viewdidload];
    // do any additional setup after loading the view.
    customtabview * tabview = [customtabview tableviewwithdatasource:self];
    
    [self.view addsubview:tabview];
    
}

xlb文件中只有一个 uitabview控件
