小编vis*_*hnu的帖子

我有一个ViewController嵌入在测试中的测试NavigationController.在测试中,ViewController我有一个WebView按钮.当我点击button它导航到SafariViewController它并且它正在加载给定的URL.在这WebView当我点击"完成"按钮,它调用名为委托方法safariViewControllerDidFinish.但这SafariViewController并没有被驳回.

这是我的代码.

- (IBAction)bannerWebviewAction:(id)sender {
    NSURL *urls = [NSURL URLWithString:@"http://www.google.com"];
    SFSafariViewController safariVC = [[SFSafariViewController alloc] initWithURL:urls];
    [self showViewController:safariVC sender:nil];
    safariVC.delegate = self;
}

#pragma SFSafariViewControllerDelegate
-(void)safariViewControllerDidFinish:(SFSafariViewController *)controller {
    // Done button pressed
    [controller dismissViewControllerAnimated:YES completion:nil];  
}

完成button是呼唤,观点不是解雇.我检查日志中self和controller,两者都是正确的.

我正面临着UITableView行分隔符的问题.对于替代行,可以看到该行.

将高度为1的UIView添加到单元格将给出解决方案,但这不是正确的方法.以下代码适用于iOS 8,但在9中它表现出不同的性质.

- (IBAction)curencySelect:(id)sender {
    currencyTable = [[UITableView alloc]initWithFrame:CGRectMake(29, 257, 265,113) style: UITableViewStylePlain];
}
#pragma mark -
#pragma mark UITableViewDelegate
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{

    return 1;
}

- (NSInteger)tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section{


    return currencyArray.count;

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{


       UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MyIdentifier"];

       if (cell == nil) {

            cell =[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"MyIdentifier"];
       }



    cell.textLabel.text = [currencyArray objectAtIndex:indexPath.row];

    return cell;
}

提前致谢.

我想以X年Y个月Z天的形式计算年龄.这是我的代码

 NSString *dateString = @"15-Sep-1997";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc]init];
[dateFormatter setDateFormat:@"dd-MMM-yyyy"];

NSDate *PrevDate = [dateFormatter dateFromString:dateString];


NSDate *today = [NSDate date];
NSLog(@"Prev date = %@", PrevDate);
NSLog(@"today =%@", today);
NSInteger  years;
NSInteger months;
NSInteger days;

NSCalendar *calendar = [NSCalendar currentCalendar];
unsigned unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit;
NSDateComponents *dateComponentsNow = [calendar components:unitFlags fromDate:today];
NSDateComponents *dateComponentsBirth = [calendar components:unitFlags fromDate:PrevDate];

if (([dateComponentsNow month] < [dateComponentsBirth month]) ||
    (([dateComponentsNow month] == [dateComponentsBirth month]) && ([dateComponentsNow day] < [dateComponentsBirth day]))) { …
