我有一个文本框,我希望用户只输入数字.我在那里实现了数字键盘.但是,如果有人将我的应用程序放在后台并从其他应用程序复制一些字符串并返回到我的应用程序并粘贴它,它会成功地将字符串内容粘贴到我的数字文本字段中.我该如何限制这种情况?
我正在第三次尝试使用iPhone20框架,我似乎无法弄清楚如何将表格单元格的背景更改为UIImage而不仅仅是颜色.谁能帮我吗?
我创建了一个PowerShell脚本,可以从Management Shell中完美运行.我试图把它安装在Windows Server 2008 R2的计划任务工作,我不能确定如何通过我的字符串数组参数的参数.
这是我的脚本的相关部分:
[CmdletBinding()]
param(
[Parameter(Mandatory=$true)]
[String]
$BaseDirectory,
[String]
$BackupMethod = "Full",
[Int]
$RemoveOlderThanDays = 0,
[String]
$LogDirectory,
[Int]
$LogKeepDays = 7,
[String[]]
$AdditionalDirectories
)
if ($AdditionalDirectories -and $AdditionalDirectories.Count -gt 0) {
Write-Host " Additional Directories to be included:" -ForegroundColor Green
$AdditionalDirectories | ForEach-Object {
Write-Host " $_" -foregroundcolor green
}
}

给出麻烦的参数是最后一个,$AdditionalDirectories.
如果我像这样从Management Shell运行脚本,它可以很好地工作:
.\FarmBackup.ps1 \\SomeServer\Backups Full 0 D:\Logs\Backups 0 "D:\Documents\PowerShell Scripts","D:\SomeFolder"

仪器报告我在代码的第一行有内存泄漏.但是你可以在代码的底部看到我发布了flipcoin对象.我没有其他分配线,所以我不明白可能是什么问题?我猜有一部分内存管理我误解了,有人可以给我一个暗示,这可能会导致这个报告泄漏吗?
flipCoin= [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"0000.png"]];
CGRect frameX;
UIImageView *coinFlipImage = [[UIImageView alloc] initWithImage:[UIImage
imageNamed:@"0000.png"]];
frameX = coinFlipImage.frame;
frameX.origin.x = (480/2) - (frameX.size.width/2);
frameX.origin.y = (320/2) - (frameX.size.height/2);
[flipCoin initWithFrame:frameX];
flipCoin.animationImages = myImages;
flipCoin.animationDuration = 1.4; // seconds
flipCoin.animationRepeatCount = 1; // 0 = loops forever
//[flipCoin startAnimating];
[self.view addSubview: flipCoin];
[coinFlipImage release];
[flipCoin release];
