【问题描述】:
我正在尝试将我的 NSDate 放入单元格内的 UILabel 中。现在我遇到了这个问题
*** 由于未捕获的异常“NSInvalidArgumentException”而终止应用程序,原因:“-[__NSTaggedDate rangeOfCharacterFromSet:]: unrecognized selector sent to instance 0xe41bd157d5000000”
这是我到目前为止所做的
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UILabel *dateLabel = [[UILabel alloc] initWithFrame:CGRectMake(200, 10, 50, 130)];
NSDate *date = [[myArray objectAtIndex:indexPath.row] objectForKey:@"Date"];
typeLabel.tag =2;
typeLabel.text = date;
[[cell.contentView viewWithTag:2]removeFromSuperview];
[cell.contentView addSubview:dateLabel];
return cell;
}
{
Start = [[[[array objectAtIndex:0] valueForKey:@"StartTime"]objectAtIndex:index]valueForKey:@"text"];
Start = [Start stringByReplacingOccurrencesOfString:@"\n" withString:@""];
Start = [Start stringByReplacingOccurrencesOfString:@"\t" withString:@""];
Stream = [Stream stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
NSString* format = @"yyyy-MM-dd HH:mm:ss";
NSDateFormatter* formatterUtc = [[NSDateFormatter alloc] init];
[formatterUtc setDateFormat:format];
[formatterUtc setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:8]];
// Cast the input string to NSDate
NSDate* utcDate = [formatterUtc dateFromString:Start];
// Set up an NSDateFormatter for the device's local time zone
NSDateFormatter* formatterLocal = [[NSDateFormatter alloc] init];
[formatterLocal setDateFormat:format];
[formatterLocal setTimeZone:[NSTimeZone localTimeZone]];
// Create local NSDate with time zone difference
NSDate* localDate = [formatterUtc dateFromString:[formatterLocal stringFromDate:utcDate]];
NSLog(@"utc: %@", utcDate);
NSLog(@"local: %@", localDate);
[dict setObject:localDate forKey:@"Date"];
[myArray addObject:dict];
}
