iOS的 - 无法加载表视图

Question

我用一个简单的表格视图一个小问题，我无法显示它的应用程序崩溃时，我打开看，这里是代码：

familySelect .H：

// familySelect.h 
// fptNew 
// 
// Created by Marco on 14/09/11. 
// Copyright 2011 __MyCompanyName__. All rights reserved. 

#import <UIKit/UIKit.h> 


@interface familySelect : UIViewController { 
    NSArray *colorNames; 
    IBOutlet UITableView *tableView; 
} 

@property (nonatomic, retain) NSArray *colorNames; 

@end 

familySelect.m：

// familySelect.m 
// fptNew 
// 
// Created by Marco on 14/09/11. 
// Copyright 2011 __MyCompanyName__. All rights reserved. 

#import "familySelect.h" 


@implementation familySelect 

@synthesize colorNames; 

// The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad. 
/* 
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { 
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; 
    if (self) { 
     // Custom initialization. 
    } 
    return self; 
} 
*/ 


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib. 
- (void)viewDidLoad { 
    [super viewDidLoad]; 

    NSLog(@"eseguito"); 
    self.colorNames = [[NSArray alloc] initWithObjects:@"Red", @"Green", @"Blue", @"Indigo", @"Violet", nil]; 

    //UILabel *label = (UILabel *)[self.view viewWithTag:111]; 
    //label.backgroundColor = [UIColor colorWithRed:0.2f green:0.3f blue:0.4f alpha:0.00000f]; 

} 



- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { 
    // Overriden to allow any orientation. 
    return YES; 
} 


- (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. 
} 


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

// Customize the number of rows in the table view. 
- (NSInteger)tableView:(UITableView *)TableView numberOfRowsInSection:(NSInteger)section { 
    return [self.colorNames count]; 
} 

// Customize the appearance of table view cells. 
- (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 = [self.colorNames objectAtIndex: [indexPath row]]; 

    return cell; 
} 

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

@end 

，这是控制台输出，当它崩溃：

不明白这有什么错我的代码

感谢您的帮助:)

UPDATE：

有在厦门国际银行文件，我不要连接。

的tableView连接

和文件的所有者连接

是正确的方式联系起来？

Answer 1

您需要实现UITableView delegates-

@interface familySelect : UIViewController <UITableViewDelegate,UITableViewDataSource> 

而且，由于你已经宣布tableView作为IBOutlet，我猜你做了一个中笔尖。您还必须在笔尖制作tableView的参考插座。只需右键单击tableView并使用正确的元素连接不同的属性。

Answer 2

您必须声明表视图的属性。就像这样：

@property(nonatomic,retain) IBOutlet UITableView *tableView;

和您的接口声明应该是这样的：

@interface familySelect : UIViewController<UITableViewDelegate,UITableViewDataSource> 
{ 
     NSArray *colorNames; 
     UITableView *tableView; 
} 

干杯！
