Question

我有三个文本字段，其中我想显示当前时间。在第一个文本字段中，它仅显示小时数，在第二个文本字段中仅显示分钟，在最后一个文本字段中显示上午或下午。为了获得当前时间，我使用此代码，但如何根据我的要求显示？代码......

- (void)viewDidLoad {

NSDate* date = [NSDate date];

//Create the dateformatter object

NSDateFormatter* formatter = [[[NSDateFormatter alloc] init] autorelease];

//Set the required date format

[formatter setDateFormat:@"HH:MM"];

//Get the string date

NSString* str = [formatter stringFromDate:date];

//Display on the console

NSLog(@"%@",str);

//Set in the lable

time_label.text=[NSString stringWithFormat:@"%@ AM",str];
[super viewDidLoad];

}

提前致谢...

Answer 1

NSDate* date = [NSDate date];

//Create the dateformatter object

NSDateFormatter* formatter = [[[NSDateFormatter alloc] init] autorelease];

//Set the required date format

[formatter setDateFormat:@"hh MM a"];

//Get the string date

NSString* str = [formatter stringFromDate:date];

//Display on the console

NSLog(@"%@",str);
NSMutableArray *Arr=[str componentsSeparatedByString:@" "];

textFeild1.text=[Arr objectAtIndex:0]; //hoursTextFeild
textFeild2.text=[Arr objectAtIndex:1]; //minutesTextFeild
textFeild3.text=[Arr objectAtIndex:2];//Am/Pm TextFeild

- (void)viewDidLoad {

    NSDate* date = [NSDate date];

    //Create the dateformatter object

    NSDateFormatter* formatter = [[[NSDateFormatter alloc] init] autorelease];

    //Set the required date format

    [formatter setDateFormat:@"HH:MM"];

    //Get the string date

    NSString* str = [formatter stringFromDate:date];

    //Display on the console

    NSLog(@"%@",str);

    //Set in the label
   //seperate its components
    NSMutableArray *array = [str componentsSeperatedByString:@" "];

   [firstTextField setText:[array objectAtIndex:0]];
   [secondTextField setText:[array objectAtIndex:1]];
   [thirdTextField setText:@"AM/PM"];


    [super viewDidLoad];
    }

如何在不同的文本字段中显示时间段？
