Question

我有按钮的视图。当我按下按钮时，uisplitview应显示。问题是使用tableview（splitview的左=主视图）。详细视图（右）显示正确。左边一个是空的，因为没有调用cellForRowAtIndexPath。我的.h文件扩展了UISplitViewController，并在.m文件的viewDidLoad中执行此操作：

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];

我的left.h：

@interface Left : UIViewController  <UITableViewDataSource, UITableViewDelegate> {

NSMutableArray *tableData;
UITableView *table;
}

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

我的左.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表？

Answer 1

你必须

替换此

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

到

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

因为我曾经习惯和自己打电话是你合成了这张桌子。

所以我们必须喜欢这个

UITableView委托方法没有为uiSplitView的主视图调用
