ios - 正在获取:在“ViewController *”类型的对象上找不到属性“getFlower”

我正在关注“ Sams Teach Yourself iOS 6”，并且我尝试对此错误进行故障排除，但未成功。

这是我的ViewController.h文件：

@interface ViewController : UIViewController

@property (weak, nonatomic) IBOutlet UISegmentedControl *colorChoice;
@property (weak, nonatomic) IBOutlet UIWebView *flowerView;
@property (weak, nonatomic) IBOutlet UIWebView *flowerDetailView;

- (IBAction)toggleFlowerDetail:(id)sender;
- (IBAction)getFlower:(id)sender;

@end

我得到的错误是在ViewController.m文件的此行[self.getFlower：nil];上：

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.flowerDetailView.hidden=YES;
    [self.getFlower:nil];

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)toggleFlowerDetail:(id)sender {
        self.flowerDetailView.hidden=! [sender isOn];
}

- (IBAction)getFlower:(id)sender {
    NSURL *imageURL;
    NSURL *detailURL;
    NSString *imageURLString;
    NSString *detailURLString;
    NSString *color;
    int sessionID;

    color=[ self.colorChoice titleForSegmentAtIndex:self.colorChoice.selectedSegmentIndex];

    sessionID=random() % 50000;

    imageURLString=[[NSString alloc] initWithFormat: @"http://www.floraphotographs.com/showrandomios.php?color=%@&session=%d", color, sessionID];

    detailURLString=[[NSString alloc] initWithFormat: @"http://floraphotographs.com/detailios.php?session=%d", sessionID];

    imageURL=[[NSURL alloc]initWithString:imageURLString];
    detailURL=[[NSURL alloc]initWithString:detailURLString];

    [self.flowerView loadRequest: [NSURLRequest requestWithURL:imageURL]];
    [self.flowerDetailView loadRequest:[NSURLRequest requestWithURL:detailURL]];
    self.flowerDetailView.backgroundColor=[UIColor clearColor];
}

@end

方法getFlower已在头文件中声明，所以为什么不能在实现文件中使用它？

最佳答案

这个：

[self.getFlower:nil];

应该：

[self getFlower:nil];

这是一种方法，而不是属性。
