未为 uiSplitView 的主视图调用 UITableView 委托方法

Question

我有一个带有按钮的视图。当我按下按钮时，应该显示 uisplitview。问题在于表视图（分割视图的左=主视图）。详细视图（右）正确显示。左侧为空，因为未调用 cellForRowAtIndexPath。 我的 .h 文件扩展了 UISplitViewController，在 .m 文件的 viewDidLoad 中我这样做：

Left *l = [[Left alloc] initWithNibName:@"Left" bundle:nil];
Right *d = [[Right alloc] initWithNibName:@"Right" bundle:nil];
// Update the split view controller's view controllers array.
NSArray *viewControllers = [[NSArray alloc] initWithObjects:l, d, nil];
self.viewControllers = viewControllers;
[viewControllers release];

My left.h:

@interface Left : UIViewController  <UITableViewDataSource, UITableViewDelegate> {

NSMutableArray *tableData;
UITableView *table;
}

@property (nonatomic, retain) NSMutableArray *tableData;
@property (nonatomic, retain) IBOutlet UITableView *table;

My left.m:

    #import "Left.h"


   @implementation Left

   @synthesize tableData,table;

    - (id)initWithStyle:(UITableViewStyle)style
  {
self = [super initWithStyle:style];
if (self) {
    // Custom initialization
}
return self;
}

- (void)dealloc
{
[super dealloc];
}

- (void)didReceiveMemoryWarning
{
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];

// Release any cached data, images, etc that aren't in use.
 }

#pragma mark - View lifecycle

 - (void)viewDidLoad
 {

[super viewDidLoad];
table = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain]; 
table.delegate = self; 
table.dataSource = self; 

table.autoresizesSubviews = YES; 
tableData=[[NSMutableArray alloc] initWithObjects:@"bazinga",@"buzz", nil];

//NSLog(@"velikost : %d", [tableData count]);
[self.view addSubview:table];
}

 - (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}


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

// Return the number of sections.
return 0;
}

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

// Return the number of rows in the section.
NSLog(@"size: %d", [tableData count]);
return [tableData 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];
}

// Configure the cell...
cell.textLabel.text=[tableData objectAtIndex:indexPath.row];

return cell;
 }


   }

如何用数据填充主视图的表？

Answer 1

你必须

替换它

    table = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain]; 

，因为

   self.table = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain]; 

我曾经用 self 来调用你已经合成了表格。

所以我们必须喜欢这个
