如何读取的plist数据的UITableView

Question

可能重复：
How to Get Data from a PList into UITableView?

我有字典，每个dictionary.show串号一个的plist到URL below.and这个名单的物品在plist中的成千上万。

现在要显示这些清单到tableview中

。

现在我怎么能显示到UITableView

这plist我想做的是：

- (id)readPlist:(NSString *)fileName 
{ 

NSString *error; 
NSPropertyListFormat format; 
id plist; 

NSString *localizedPath = [[NSBundle mainBundle] pathForResource:@"A" ofType:@"plist"]; 

dic =[NSDictionary dictionaryWithContentsOfFile:localizedPath]; 



plist = [NSPropertyListSerialization propertyListFromData:dic mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&error]; 
if (!plist) { 
    NSLog(@"Error reading plist from file '%s', error = '%s'", [localizedPath UTF8String], [error UTF8String]); 
    [error release]; 
} 

return plist; 
} 


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

dict =[self readPlist:@"A"]; 
return dict.allKeys.count; 
} 

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

dict = [self readPlist:@"A"]; 
key = [dict.allKeys objectAtIndex:section]; 
return [[dict valueForKey:key] count]; 

} 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
static NSString *CellIdentifier = @"Cell"; 

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
if (cell == nil) { 
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 
} 

    cell.textLabel.text = [[dict objectForKey:key] objectAtIndex:indexPath.row]; 

return cell; 
}

UPDATE 2：您需要在xib或ViewController中设置delegate和datasource作为tableView。

在你ViewController.h文件

@interface ViewController:UIViewController <UITableViewDelegate, UITableDataSource> 

试试这个代码，我已经为你写的。

- (void)viewDidLoad { 

    tableView.delegate = self; 
    tableView.dataSource = self; 

    NSString *path = [[NSBundle mainBundle] pathForResource:@"Filename" ofType:@"plist"]; 
    NSArray *contentArray = [NSArray arrayWithContentsOfFile:path]; 
    // Having outlet for tableArray variable. 
    tableArray = [[NSMutableArray alloc]initWithArray:contentArray copyItems:YES]; 

    [super viewDidLoad]; 
    // Do any additional setup after loading the view from its nib. 
} 

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { 
    return [tableArray count]; 
} 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
    // In your case dictionary contains strings with keys and values. The below line returns dictionary only. not array.. 
    NSDictionary *dictionary = [tableArray objectAtIndex:section]; 
    return dictionary.allKeys.count; 
} 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 
    static NSString *cellIdentifier = @"MyCell"; 

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; 
    if (cell == nil) { 
     cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:cellIdentifier]; 
    } 
    NSDictionary *dictionary = [tableArray objectAtIndex:indexPath.section]; 
    NSArray *keysArray = dictionary.allKeys; 
    // This below line display the key in textLabel 
    cell.textLabel.text = [keysArray objectAtIndex:indexPath.row]; 
    // Below line will display the value of a key in detailTextLabel. 
    cell.detailTextLabel.text = [dictionary valueForKey:[keysArray objectAtIndex:indexPath.row]]; 
    return cell; 
} 

更新2：我看过后，你plist在我的MAC，我发现，我们与array of dictionaries在A.plist工作。

所以，我发现有在我们的代码本身就是一个bug。不在plist文件中，您可以使用您的8000 data plist too ..其工作方式也是如此。我已经完全检查了。现在你可以得到上面的代码并开始工作。

在阵列储存的plist数据

- (id)readPlist:(NSString *)fileName 
{ 

NSString *error; 
NSPropertyListFormat format; 
id plist; 

NSString *localizedPath = [[NSBundle mainBundle] pathForResource:@"A" ofType:@"plist"]; 

// declare your array in .h file 
    array = [NSArray arrayWithContentsOfFile:localizedPath];  

plist = [NSPropertyListSerialization propertyListFromData:dic mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&error]; 
if (!plist) { 
    NSLog(@"Error reading plist from file '%s', error = '%s'", [localizedPath UTF8String], [error UTF8String]); 
    [error release]; 
} 

return plist; 
} 

，然后把它写在表

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
static NSString *CellIdentifier = @"Cell"; 

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
if (cell == nil) { 
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 
} 

    cell.textLabel.text = [array objectAtIndex:indexPath.row] valueForKey:@"keyname"];; 

return cell; 
}
