我正在Phonegap为IOS 构建一个应用程序.我用Cordova相机plugin进行个人资料图片上传.我的示例代码是:
navigator.camera.getPicture(that.imageDataSuccessCallback, that.imageDataErrorCallback, { quality: 10, destinationType: 1, encodingType: 0, allowEdit: true, correctOrientation: true, sourceType:0 });

当我点击该特定按钮时,我收到警告
THREAD WARNING: ['Camera'] took '290.006104' ms. Plugin should use a background thread.

它阻止了我的应用.任何人都可以建议如何解决这个问题?
EventKit当尝试将事件添加到日历但访问被拒绝时,我希望我请求对日历的许可。它仅在第一次使用应用程序时询问,如果您在设置中拒绝访问,它不会提示用户再次授予访问权限。请帮忙。
额外的功劳:我还希望它检查日历中是否已存在该事件,如果存在,请对其进行编辑。对此的任何帮助也将不胜感激!!
这是我的代码:
func addToCalendar(){
let eventStore = EKEventStore()
let startDate = NSDate()
let endDate = startDate.dateByAddingTimeInterval(60 * 60) // One hour
if (EKEventStore.authorizationStatusForEntityType(.Event) != EKAuthorizationStatus.Authorized) {
eventStore.requestAccessToEntityType(.Event, completion: {
granted, error in
self.createEvent(eventStore, title: "\(self.meal.text!)", startDate: startDate, endDate: endDate)
})
} else {
createEvent(eventStore, title: "\(self.meal.text!)", startDate: startDate, endDate: endDate)
}
}
func createEvent(eventStore: EKEventStore, title: String, startDate: NSDate, endDate: NSDate) {

event.title = title
event.startDate = startDate

因此,我无法执行某些操作以响应userActivity.webpageURL应用程序运行或以前安装在设备上时通常会遇到的操作.这是正常的行为吗?即如果未安装该应用,通用链接将仅作为从应用商店安装应用的媒介?
我已经用底表实现了Google地图。但是,当我检查布局时,地图位于屏幕顶部,而不占据屏幕的整个宽度和高度。我已经尝试了多种方法来解决此问题,但是没有运气。
