我正在使用ant-release我的Android应用程序的一步构建.

我的build.properties看起来像这样:

application.package=xxxxx
key.store=sonr
key.alias=sonr labs
key.store.password=xxxx
key.alias.password=xxxx

当我运行ant-release时,一切都很好,除了应用程序签名.我收到错误:

-release-prompt-for-password:

-release-nosign:
     [echo] No key.store and key.alias properties found in build.properties.
     [echo] Please sign /Users/syalam/Documents/git/joeborn-sonr/sonr/bin/SONR-release-unsigned.apk manually
     [echo] and run zipalign from the Android SDK tools.

我该如何解决这个问题？

PS.我按照本教程来完成构建过程http://www.androidengineer.com/2010/06/using-ant-to-automate-building-android.html

我有7台设备插入我的开发机器.

通常情况下,我adb install <path to apk>只能安装到一台设备上.

现在我想在我所有的7个连接设备上安装我的apk.我怎样才能在一个命令中执行此操作？我想也许要运行一个脚本.

打开项目文件时,Xcode一直在崩溃.我已经能够打开好几周了.不确定如何诊断.它只会崩溃一个特定的项目.

除了语言差异Javascript vs. Objective-J Cappuccino在SproutCore中提供了哪些好处,反之亦然？

就长期预测而言,SproutCore是否比卡布奇诺更"支持",因为它得到了Apple的支持？

我想在两者之间做出选择.我熟悉JavaScript和Objective-C.

我试图将模态视图控制器显示为UIPresentationFormSheet.视图出现,但我似乎无法调整大小.我的XIB具有适当的高度和宽度,但是当我这样调用它时它似乎被覆盖了:

composeTweetController = [[ComposeTweet alloc] initWithNibName:@"ComposeTweet" bundle:nil];
composeTweetController.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:composeTweetController animated:TRUE];

有什么想法吗？我正在使用iPhone SDK 3.2 beta 4

我有一个现有的NSDictionary,它具有:

{
    "charts_count" = 2;
    "created_at" = "2010-04-12T16:37:32Z";
    exchange = NASDAQ;
    "followers_count" = 259;
    id = 8404;
    industry = "<null>";
    "messages_count" = 1436;
    ric = "GRPN.O";
    sector = "<null>";
    symbol = GRPN;
    title = Groupon;
    "updated_at" = "2011-09-05T04:17:56Z";
}

我如何获取这些内容并将其放入新的NSMutableDictionary中？

出于某种原因,当我尝试使用CALayer时出现链接器错误:

  "_OBJC_CLASS_$_CALayer", referenced from:

我导入了以下标题:

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>

码:

arrowImage = [[CALayer alloc] init];

默认的Eclipse格式化程序以非常有趣的方式格式化我的Java代码.

例如:hello.show().x().y()奇怪地将其格式化为x()和.y(),并放在一个单独的行上.

还有其他基本格式化程序可以做得更好吗？

非常欢迎示例和链接.

我希望能够在用户点击键盘外的任何位置时关闭iPhone键盘.我该怎么做呢？我知道我需要解雇响应者,但需要知道当用户从键盘空间中弹出时如何实现它.

我有2个视图控制器以模态方式呈现.

A presents B which presents C.

当我解雇CI时也想解雇B. 但我不知道该怎么做:

解雇C:

[self dismissModalViewControllerAnimated:YES]
//[delegate dismissB] //this doesn't work either when i create a delegate pattern

现在我离开了B.如何从C中解雇B？
