我一直试图在iPad上安装一个数字键盘,但是当我在TextField上设置一个数字键盘时,我得到一个带有数字和ponctuation的普通键盘.但是我在模拟器上发现了几个错误,我真的不知道这是不是另一个.
iPad上有标准键盘吗?
我已经注册了标准的iPhone开发人员计划,并且我已成功为我的iMac创建了配置文件.但我也有一台MacBook Pro,我在旅途中使用它.但是使用标准的iPhone开发人员计划似乎没有办法让2台计算机工作,除非我在切换机器时花时间撤销并重新创建/重新验证证书颁发机构.
我对吗?或者有没有办法在多台机器上使用相同的CA?
我有两个视图需要以模态方式显示,一个接一个.如果我们连续解雇和显示,这不起作用,如下所示:
[rootController dismissModalViewControllerAnimated: YES];
[rootController presentModalViewController: psvc animated: YES];
Run Code Online (Sandbox Code Playgroud)
第二个模态视图根本没有显示出来.
我见过一个像这样的修复:
[rootController dismissModalViewControllerAnimated: YES];
[[UIApplication sharedApplication] beginIgnoringInteractionEvents];
[self performSelector: @selector(seekModal) withObject: nil afterDelay: 0.5];
[[UIApplication sharedApplication] endIgnoringInteractionEvents];

问题是这不会一直有效(所需的延迟有时是优越的).
另一个可能的解决方法是消除动画:
[rootController dismissModalViewControllerAnimated: NO];
[rootController presentModalViewController: psvc animated: YES];

但我真的很想保留动画,以保持第一个模态不受影响的感觉.有什么建议?

我有一个Elastic Beanstalk工作者,一次只能运行一个任务,这需要一些时间(从几分钟到,希望不到30分钟),所以我在SQS上排队.

我已经在模拟器上禁用了"请勿再询问"选项集,并认为我可以在以后重新启用它,但现在我无法找到方法.
有人能指出我在哪里更改此设置?
谢谢.
我已经读过Objective-C没有类级别属性的地方,但是通过声明类似的东西(在类接口之前)可以实现相同的目的:
static NSInteger initCount;
Run Code Online (Sandbox Code Playgroud)
我正在使用initialize方法将变量初始化为零:
// interface
+ (void) initialize;
// implementation
+ (void) initialize {
initCount = 0;
}
Run Code Online (Sandbox Code Playgroud)
在创建实例/ dealloc'd时递增/递减:
- (id) init {
self = [super init];
initCount++;
return self;
}
- (void) dealloc {
[name release];
initCount--;
[super dealloc];
}

但XCode一直警告我"'initCount'定义但未使用".
有没有办法解决这个问题,还是应该忽略警告?
