两个TableView的复用
代码
1. TableView的代理方法实现TableView的复用，同理，推两个TableView的复用。
实现：
.h文件
#import
@classHomeDropdown;
@protocolHomeDropdownDataSource
-(NSInteger)numberOfRowsInMainTable:(HomeDropdown*)homeDropdown;
-(NSString*)homeDropdown:(HomeDropdown*)homeDropdown
titleOfRowsInMainTable:(NSInteger)row;
-(NSArray*)homeDropdown:(HomeDropdown*)homeDropdown
subdataForRowInMainTable:(NSInteger)row;
//@optional
//可选方法
//-(NSString
*)titleOfRowsInMainTable:(UITableView *)mainTable;
@end
@interfaceHomeDropdown :UIView
+(instancetype)dropdowm;
@property(nonatomic,strong)NSArray*categories;
@property(nonatomic,strong)id dataSource;
@end
.m文件
#import"HomeDropdown.h"
#import"CategoryModel.h"
#import"HomeDropdownMainCell.h"
#import"HomeDropdownSubCell.h"
#import"MTRegion.h"
@interfaceHomeDropdown()
@property(weak,nonatomic)IBOutletUITableView*mainTable;
@property(weak,nonatomic)IBOutletUITableView*allowTable;
//@property
(nonatomic,strong) CategoryModel *selectedCategory;
@property(nonatomic,assign)NSIntegerselectedMainRow;
@property(nonatomic,strong)NSArray*regionArray;
@end
@implementationHomeDropdown
+(instancetype)dropdowm{
return[[[NSBundlemainBundle]loadNibNamed:@"HomeDropdown"owner:niloptions:nil]firstObject];
}
-(void)awakeFromNib{
//不需要跟随父空间的尺寸变化而伸缩
self.autoresizingMask=UIViewAutoresizingNone;
self.backgroundColor=[UIColorredColor];
}
-(NSInteger)tableView:(UITableView*)tableView numberOfRowsInSection:(NSInteger)section{
if(tableView==self.mainTable) {
NSLog(@"%ld",(long)[self.dataSourcenumberOfRowsInMainTable:self]);
return[self.dataSourcenumberOfRowsInMainTable:self];
}else{
//return [self.dataSource homeDropdown:selfsubdataForRowInMainTable:self.selectedMainRow].count;
returnself.regionArray.count;
}
}
-(UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath{
//NSLog(@"datasource %@",self.dataSource);
UITableViewCell*cell=nil;
if(tableView==self.mainTable) {
//主表
cell=[HomeDropdownMainCellcellWithTableView:tableView];
cell.textLabel.text=[self.dataSourcehomeDropdown:selftitleOfRowsInMainTable:indexPath.row];
if([self.dataSourcehomeDropdown:selfsubdataForRowInMainTable:indexPath.row]) {
//有一个圆形button按钮
cell.accessoryType=UITableViewCellAccessoryDetailDisclosureButton;
}else{
cell.accessoryType=UITableViewCellAccessoryNone;
}
}else{
//从表
if(self.regionArray.count!=0){
cell=[HomeDropdownSubCellcellWithTable:tableView];
NSString*region=self.regionArray[indexPath.row];
cell.textLabel.text=region;
}
}
returncell;
}
-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath{
if(tableView==self.mainTable) {
//self.selectedCategory=self.categories[indexPath.row];
self.selectedMainRow=indexPath.row;
self.regionArray=[self.dataSourcehomeDropdown:selfsubdataForRowInMainTable:indexPath.row];
//刷新表格
[self.allowTablereloadData];
}else{
NSLog(@"%@",self.regionArray[indexPath.row]);
}
}
实现代理方法：
-(NSInteger)numberOfRowsInMainTable:(HomeDropdown*)homeDropdown{
return[MTMetaToolcategories].count;
}
-(NSString*)homeDropdown:(HomeDropdown*)homeDropdown
titleOfRowsInMainTable:(NSInteger)row{
CategoryModel*categoryModel=[MTMetaToolcategories][row];
returncategoryModel.name;
}
-(NSArray*)homeDropdown:(HomeDropdown*)homeDropdown
subdataForRowInMainTable:(NSInteger)row{
CategoryModel*categoryModel=[MTMetaToolcategories][row];
returncategoryModel.subcategories;
}
