我一直在尝试在新计算机上用Xcode创建Cordova/Phonegap应用程序.但它似乎没有用.当我在模拟器或我的iPhone上运行应用程序时,我收到一条错误消息,指出找不到'libCordova.a'.

1条错误消息和5个问题:

/Users/Tim/Documents/Dropbox/Applicaties/Business/FirstProject/Xcode/FirstProject.xcodeproj

clang: error: no such file or directory: '/Users/Tim/Library/Developer/Xcode/DerivedData/FirstProject-ctanrqwggcfoubbeqbjrfvcqozpg/Build/Products/Debug-iphoneos/libCordova.a'

• Cordova版本2.1.0
• Xcode版本4.5.1

我无法在我的计算机上安装最新的cordova,在版本2.0.0上有一个安装程序,但在最新版本中这已经消失了？我已经将'Build Active Architecture Only'设置为Yes,将'Build Location'设置为Unique.

非常感谢你提前.

我正在尝试制作一个CSS按钮.如下所示,我无法为角落的第二个HTML元素创建渐变.通常我会使用边框或只是旋转一个元素来创建一个带渐变的三角形,但问题是我的三角形不是90度的正方形.

所需设计:(灰度,视网膜200%缩放)

我的CSS按钮:(蓝色,视网膜200%缩放)

有没有更好的方法来创建这个按钮与CSS？

http://jsfiddle.net/G8ZBz/或简单阅读如下:

HTML代码

<div class="button">
    <div class="button-inside"></div>
</div>

CSS

.button {
    width: 225px;
    height: 60px;
    background: #2983d2;
}
.button:before {
    position: absolute;
    width: 0px;
    height: 0px;
    left: -13px;
    content: "";
    display: block;
    border-top: 30px solid transparent;
    border-bottom: 30px solid transparent;
    border-right: 13px solid #2983d2;
}
.button:after {
    position: absolute;
    width: 0px;
    height: 0px;
    top: 0;
    right: -13px;
    content: "";
    display: block;
    border-top: 30px solid transparent;
    border-bottom: 30px solid transparent;
    border-left: 13px solid #2983d2;
} …
