addImg() {
if (this.imagePaths.length == 3) {
let tipLoader = this.loadingCtrl.create({
content: "最多添加3张!",
spinner: 'hide',
duration: 800,
showBackdrop: true
});
tipLoader.present();
return;
}

buttons: [
{
text: '拍照',
handler: () => {
this.takePhoto();
}
},
{

}
},
{

console.log('取消选择图片');
}
}
]
});
actionSheet.present();
}；
