如何解决如何使用Titanium为iPhone应用程序创建星级评定控件？
| 我正在使用Titanium框架构建iPhone应用程序。我需要在我的应用中使用5星级评分控件，就像在应用商店中找到的那样。作为临时解决方案，我正在使用滑块添加评分。我在网上找到的大多数示例都在目标C中。有人可以指导我使用钛实现这一目标。 问候解决方法
您只需要创建一个“ 0”并在其中填充所需的按钮数量，然后为它们分配一个点击事件即可。
var rateView = Ti.UI.createView(),max = 5,min = 1; // used in the flexMin and flexMax
function rate(v) {
// rate code storage goes here
// your choice on if you want to have separate images of each rating or run a loop
// based on the value passed in to change a set number of stars to their alternate
// image
}
var flexMin = Ti.UI.createButton({
systemButton: Ti.UI.iPhone.SystemButton.FLEXIBLE_SPACE,top: 0,left: 0,height: rateView.height
});
flexMin.addEventListener(\'click\',function(e) {
rate(min);
});
var flexMax = Ti.UI.createButton({
systemButton: Ti.UI.iPhone.SystemButton.FLEXIBLE_SPACE
top: 0,right: 0,height: rateView.height
});
flexMax.addEventListener(\'click\',function(e) {
rate(max);
});
rateView.add(flexMin);
rateView.add(flexMax);
var stars = [];
for(var i=1;i<max;i++) {
stars[i] = Ti.UI.createButton({
// styling including the darker or light colored stars you choose,\'rating\': i
});
stars[i].addEventListener(\'click\',function(e) {
rate(e.source.i);
});
}
