ios - iOS 应用程序中的 "Expected Identifier"错误

Question

我制作了一个非常基本的 iOS 应用程序，它在 viewDidLoad 上的标签中显示时间。我在这行代码中收到预期标识符错误:

NSString *myTime = [myDateFormatter stringFromDate:[*myDate]];

这是 ViewController.m 文件:

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

@synthesize timeLabel;

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    NSDateFormatter *myDateFormatter = [[NSDateFormatter alloc] init];
    [myDateFormatter setDateFormat:@"HH:mm a"];
    NSDate *myDate = [[NSDate alloc] init];
    NSString *myTime = [myDateFormatter stringFromDate:myDate];
    [timeLabel setText : myTime];
}

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


@end

做了一些补充。代码已编译，但现在出现 Thread 1:SIGABRT 错误。该应用程序未在模拟器上加载，并且出现错误。这是在 main() 中给出错误的代码行:

return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));

是的，我没有链接它。它现在工作。谢谢大家!

像这样删除 *

NSString *myTime = [myDateFormatter stringFromDate:mydate];
