我可以在config.xml
中将方向设置为仅限肖像,如下所示:
<preference name="Orientation" value="portrait"/>
但是,我如何允许iPad版本的横向定位,同时仍然禁用iPhone如上所述?
据Ionic的Mike Harrison说,他说:
除了手动旋转设备,不是真的。这将是您编写用于修改cordova中的主App视图的插件
但是有一个Plugin from Ionic 1。看它。最终你也可以在Ionic 2中使用它。
使用此插件,您可以执行以下操作:
if(/(ipad)/i.test(navigator.userAgent)) {
//THIS IS THE PLUGIN IONIC 1 CODE
$scope.changeOriantationPortrait = function() {
screen.lockOrientation('portrait');
}
}
您可以从config.xml中删除首选项,并通过本机插件Screen Orientation进行定义
然后在app.component.ts
锁定电话方向:
// check if platform is not a tablet
if (platform.is('cordova') && !platform.is('tablet')) {
// lock orientation to only portrait mode
this.screenOrientation.lock(this.screenOrientation.ORIENTATIONS.PORTRAIT);
// set screen orientation to 'portrait'
globalProvier.screenOrientation = this.screenOrientation.ORIENTATIONS.PORTRAIT;
} else { // if it's tablet
// set device type to 'tablet'
globalProvier.deviceType = platform.platforms()[3];
// set current orientation type ('portrait-primary' or 'landscape-primary' or 'portrait-secondary' or landscape-secondary)
globalProvier.screenOrientation = this.screenOrientation.type;
// set listener on changing orientation
this.screenOrientation.onChange().subscribe(
() => {
globalProvier.screenOrientation = this.screenOrientation.type;
console.log("Orientation Changed to: ", this.screenOrientation.type);
}
);
}
现在,您可以动态调整布局,取决于使用globalProvier.screenOrientation
变量的平板电脑方向。在模板中添加类或使用* ngIf。
*ngIf='this.globalProvider.screenOrientation == "landscape-primary" || <h3 *ngIf='this.globalProvider.screenOrientation == "landscape-primary" || this.globalProvider.screenOrientation == "landscape-secondary"'>Orientation: landscape</h3>
