您可以創建一個從的UITableViewController繼承的自定義類。
讀取list.json文件的內容到一個數組中的代碼是:
NSString * filePath =[[NSBundle mainBundle] pathForResource:@"list" ofType:@"json"];
NSError * error;
NSString* fileContents =[NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&error];
if(error)
{
NSLog(@"Error reading file: %@",error.localizedDescription);
}
self.dataList = (NSArray *)[NSJSONSerialization
JSONObjectWithData:[fileContents dataUsingEncoding:NSUTF8StringEncoding]
options:0 error:NULL];
和標題文件是:
#import <UIKit/UIKit.h>
@interface TVNA_ReadingDataTVCViewController : UITableViewController
@end
的實現是:
#import "TVNA_ReadingDataTVCViewController.h"
@interface TVNA_ReadingDataTVCViewController()
@property NSArray* dataList;
@end
@implementation TVNA_ReadingDataTVCViewController
- (void)viewDidLoad
{
[super viewDidLoad];
[self readDataFromFile];
[self.tableView reloadData];
}
-(void)readDataFromFile
{
NSString * filePath =[[NSBundle mainBundle] pathForResource:@"list" ofType:@"json"];
NSError * error;
NSString* fileContents =[NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&error];
if(error)
{
NSLog(@"Error reading file: %@",error.localizedDescription);
}
self.dataList = (NSArray *)[NSJSONSerialization
JSONObjectWithData:[fileContents dataUsingEncoding:NSUTF8StringEncoding]
options:0 error:NULL];
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return self.dataList.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
id keyValuePair =self.dataList[indexPath.row];
cell.textLabel.text = keyValuePair[@"name"];
cell.detailTextLabel.text=[NSString stringWithFormat:@"ID: %@", keyValuePair[@"number"]];
return cell;
}
@end
最後,在您的故事板上,將此類指定爲Table View Controller的自定義類。希望這可以幫助。
