與Table結合 .h

 
#import 


@interface jsonTableView : UITableViewController
{
    NSArray *CellItem ;
}

.m

 
#import "SBJson.h"

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{

    // Return the number of sections.
    return 1;
}

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

    // Return the number of rows in the section.
    return [CellItem count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Celldata";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    
    // Configure the cell...
    cell.textLabel.text = [CellItem objectAtIndex:indexPath.row];
    
    return cell;
}

Cell 上為Label的版本

 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Celldata";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    
    // Configure the cell...
   // cell.textLabel.text = [CellItem objectAtIndex:indexPath.row];
    
    NSString *text = [CellItem objectAtIndex:indexPath.row];
   // NSString *textLong = [[NSString alloc] initWithFormat: @"%@: %@",[CellItemID objectAtIndex:indexPath.row], [CellItem objectAtIndex:indexPath.row]];
    
    UILabel *cellLabel = (UILabel *) [cell viewWithTag:2] ; //Label設Tag 2
    
    cellLabel.lineBreakMode = UILineBreakModeWordWrap; //設置換行
    cellLabel.numberOfLines = 0; //設置自動行數
    [cellLabel setText:text];

    
    return cell;
}

最外層非NSDictionary格式
[ {"ID":"1","name":"A"}, {"ID":"2","name":"B"} ]

- (void)viewDidLoad
{
    [super viewDidLoad];

    [self initParseJSONData];

}

- (void)initParseJSONData
{
    //parseJSONData
    
    NSString *jsonPath = [[NSBundle mainBundle] pathForResource:@"jsonfile" ofType:@"txt"];
    NSData *data = [NSData dataWithContentsOfFile:jsonPath];
    
    NSString *jsonReturn =  [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    
    
    SBJsonParser *parser = [[SBJsonParser alloc] init];
    
    
    NSMutableArray *jSON = [parser objectWithString:jsonReturn error:nil];
    CellItem = jSON  ;
    NSLog(@"jsonContent: %@",jSON);
    
    
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Celldata";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    
    // Configure the cell...
   // cell.textLabel.text = [CellItem objectAtIndex:indexPath.row];
 
    
    NSDictionary *jsonData = [CellItem objectAtIndex: indexPath.row];
    UILabel *cellLabel = (UILabel *) [cell viewWithTag:2] ;
    
    cellLabel.lineBreakMode = UILineBreakModeWordWrap; //設置換行
    cellLabel.numberOfLines = 0; //設置自動行數
    [cellLabel setText:[jsonData objectForKey: @"name"]];

    
    return cell;
}
