我正在使用 Titanium 并在 iOS7 上运行模拟器。我正在尝试获得一张类似翻转动画的卡片。我已经工作一半了。当前它会从 front
翻转到 back
,但是一旦我再次单击它,应用程序就会崩溃,并且我的控制台不会显示任何内容。
文档说:
要转换到的新 View 不应是另一个 View 或动画 View 的 subview 。
也许我的理解是错误的,因为我似乎无法完成这项工作。到目前为止我的代码是:
var win = Ti.UI.currentWindow;
var noThumbColors = ['#555555','#cccccc'];
var noThumbColors2 = ['#ff0000','#000'];
var views = [];
var fronts = [];
var backs = [];
for (var i = 0; i < 1; i++)
{
fronts[i] = Ti.UI.createView({
id:i,
name:"front",
width:150,
height:150,
backgroundGradient:{
type: 'linear',
startPoint: { x: '0%', y: '0%' },
endPoint: { x: '0%', y: '100%' },
colors: [ { color: noThumbColors[0], offset: 0.0}, { color: noThumbColors[1], offset: 1.0 } ],
},
currentAngle: 10
});
backs[i] = Ti.UI.createView({
id:i,
name:"back",
width:150,
height:150,
backgroundGradient:{
type: 'linear',
startPoint: { x: '0%', y: '0%' },
endPoint: { x: '0%', y: '100%' },
colors: [ { color: noThumbColors2[1], offset: 0.0}, { color: noThumbColors2[0], offset: 1.0 } ],
},
currentAngle: 10
});
win.add(backs[i]);
win.add(fronts[i]);
fronts[i].addEventListener('click', function(e)
{
log(e.source.name);
t = Ti.UI.iPhone.AnimationStyle.FLIP_FROM_LEFT;
e.source.animate({view:backs[e.source.id],transition:t});
});
backs[i].addEventListener('click', function(e)
{
log(e.source.name);
t = Ti.UI.iPhone.AnimationStyle.FLIP_FROM_RIGHT;
e.source.animate({view:fronts[e.source.id],transition:t});
});
}
function log(msg)
{
Ti.API.info(msg);
}
完成的工作代码(将生成 3 个独立来回翻转的方 block ):
var win = Ti.UI.currentWindow;
var noThumbColors = ['#555555','#cccccc'];
var noThumbColors2 = ['#ff0000','#000'];
var containers = [];
var fronts = [];
var backs = [];
for (var i = 0; i < 3; i++)
{
containers[i] = Ti.UI.createView({
top:50 + (i * 155),
width:150,
height:150
});
fronts[i] = Ti.UI.createView({
id:i,
name:"front",
width:150,
height:150,
backgroundGradient:{
type: 'linear',
startPoint: { x: '0%', y: '0%' },
endPoint: { x: '0%', y: '100%' },
colors: [ { color: noThumbColors[0], offset: 0.0}, { color: noThumbColors[1], offset: 1.0 } ],
},
currentAngle: 10
});
backs[i] = Ti.UI.createView({
id:i,
name:"back",
width:150,
height:150,
backgroundGradient:{
type: 'linear',
startPoint: { x: '0%', y: '0%' },
endPoint: { x: '0%', y: '100%' },
colors: [ { color: noThumbColors2[1], offset: 0.0}, { color: noThumbColors2[0], offset: 1.0 } ],
},
currentAngle: 10
});
containers[i].add(backs[i]);
containers[i].add(fronts[i]);
win.add(containers[i]);
}
win.addEventListener('click', function(e)
{
if (e.source.name === "front")
{
containers[e.source.id].animate({view:backs[e.source.id],transition:Ti.UI.iPhone.AnimationStyle.FLIP_FROM_LEFT});
}
else if (e.source.name === "back")
{
containers[e.source.id].animate({view:fronts[e.source.id],transition:Ti.UI.iPhone.AnimationStyle.FLIP_FROM_RIGHT});
}
});
function log(msg)
{
Ti.API.info(msg);
}
最佳答案
基于KitchenSink example app您应该对要设置动画的 View 的父对象调用 animate。我还进行了小型重构,并仅创建了一个附加到窗口的事件监听器,而不是为您创建的每个对象创建了许多函数。很好用JSHint ,这会告诉您在 for 循环中创建函数并不是最佳实践。
for (var i = 0; i < 1; i++) {
/* your code */
win.add(backs[i]);
win.add(fronts[i]);
/* both addEventListener() are removed from here */
}
win.addEventListener('click', function(e) {
var t;
if (e.source.name === 'front') {
t = Ti.UI.iPhone.AnimationStyle.FLIP_FROM_LEFT;
win.animate({view:backs[e.source.id],transition:t});
} else {
t = Ti.UI.iPhone.AnimationStyle.FLIP_FROM_RIGHT;
win.animate({view:fronts[e.source.id],transition:t});
}
});
