我可以使用右视图在UITextField右侧的文本字段中添加一个按钮,但是文本在按钮上重叠.下面是右视图按钮的代码
UIView.commitAnimations()
var btnColor = UIButton(type: .Custom)
btnColor.addTarget(self, action: #selector(self.openEmoji), forControlEvents: .TouchUpInside)
btnColor.frame = CGRect(x: CGFloat(textField.frame.size.width - 25), y: CGFloat(5), width: CGFloat(25), height: CGFloat(25))
btnColor.setBackgroundImage(UIImage(named: "send.png"), forState: .Normal)
textField.addSubview(btnColor)
请让我知道如何从右侧视图填充文本.
我试图在按钮上显示一些文字和图像.我正在使用此处的代码
let btnSort = UIButton.buttonWithType(UIButtonType.System) as! UIButton
btnSort.frame = CGRectMake(2, 74, 140, 26)
btnSort.tintColor = UIColor.whiteColor()
btnSort.setImage(UIImage(named:"immgg"), forState: UIControlState.Normal)
btnSort.imageEdgeInsets = UIEdgeInsets(top: 6,left: 100,bottom: 6,right: 14)
btnSort.titleEdgeInsets = UIEdgeInsets(top: 0,left: -30,bottom: 0,right: 34)
btnSort.setTitle("SORT", forState: UIControlState.Normal)
btnSort.layer.borderWidth = 1.0
btnSort.layer.borderColor = UIColor.whiteColor().CGColor
btnSort.addTarget(self, action: Selector("showSortTbl"), forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(btnSort)
我可以在正确的位置看到图像,但文本没有出现.我觉得titleEdgeInsets不行.
我正在做一个应用程序,它要求我向我的用户发送推送通知.
我正在使用这个例子.首先,我在点击通知栏上的通知时没有打开所需的活动但是现在已经解决了.我在应用程序处于活动状态或后台时收到通知.
然而,我的一部手机(Nexus 4有Android Kitkat 4.4)出现意外行为:当应用程序处于前台并显示消息时,它会通过广播显示通知,但是当点击通知栏上的通知时,它不会启动需要启动的活动有时它不像我的其他手机那样收到通知.

我正在尝试使用以下代码在gridview上使用Universal Image Loader从Internet加载图像.
public View getView(int position, View converView, ViewGroup parent) {
Log.v("Description", "Description is " + position);
ViewHolder mVHolder;
if (converView == null) {
LayoutInflater vi = (LayoutInflater) conted.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
converView = vi.inflate(R.layout.customgrid, null);
mVHolder = new ViewHolder();
mVHolder.mImageView = (ImageView) converView
.findViewById(R.id.imgview);
mVHolder.mTextView1 = (TextView) converView
.findViewById(R.id.textView1);
mVHolder.mTextView2 = (TextView) converView
.findViewById(R.id.textView2);
mVHolder.mTextView3 = (TextView) converView
.findViewById(R.id.textView3);
converView.setTag(mVHolder);
} else {
mVHolder = (ViewHolder) converView.getTag();
}
// mVHolder.mImageView.setImageResource(mThumbIds[position]);
// mVHolder.mImageView.setImageDrawable(LoadImageFromURL(
// mThumbIds[position]));
imageLoader.displayImage(mThumbIds[position],mVHolder.mImageView,options, animationListener);
Log.v("Names",NAMES[position] + STATES[position] + CONSTITUENCY[position]); …我正在使用Smack和Openfire服务器作为聊天客户端,所有工作都很好,比如聊天,发送新用户的邀请,获取可用用户列表等等.我不知道如果连接是什么怎么办在粘性服务中我添加了一个连接监听器连接和连接断开连接,让我们说"Internet连接"
我正在使用以下代码作为connectionlistener.
connection.addConnectionListener(new ConnectionListener() {
@Override
public void reconnectionSuccessful() {
Log.i("","Successfully reconnected to the XMPP server.");
}
@Override
public void reconnectionFailed(Exception arg0) {
Log.i("","Failed to reconnect to the XMPP server.");
}
@Override
public void reconnectingIn(int seconds) {
Log.i("","Reconnecting in " + seconds + " seconds.");
}
@Override
public void connectionClosedOnError(Exception arg0) {
Log.i("","Connection to XMPP server was lost.");
Log.v("ONMESSAGE", "Error was " + arg0.toString() + "and Now connecting");
}
@Override
public void connectionClosed() {
Log.i("","XMPP connection was closed.");
}
}); …我遵循下面的代码,我从堆栈溢出问题复制和转换.
我正在上网速度,但我不确定,如果我做对了.

我该怎么办？
1920X1080(iPhone 6s Plus)并将其放在背景视图中,然后将自动布局设置为全屏幕.ImageName@2x与的大小640X960,ImageName-667h@2x 1334X750iPhone 6,ImageName-736h@3x 1920X1080iPhone 6Plus,ImageName-568h@2x 640X1136为iPhone 5？我想对 Xcode 中的不同目标使用相同的代码。我可以使用 Duplicate 方法创建目标，然后我也可以更改方案名称。
现在真正的场景来了，我想以集中方式使用我的代码，比如新目标，我不想复制和粘贴 Main.storyboard 和 xib，所以，理想情况下会发生什么，如果我改变在一个地方的任何东西，所有目标都会共享。但问题来了，``ViewController inMain.Storyboard` 持有主项目“模块”，所以，当我运行子目标时，它无法运行。
我有一个像布巴内斯瓦尔，奥里萨邦，印度这样的地方的格式化地址。我怎样才能在php代码中获得这个地方的时区，即“亚洲/加尔各答”？
我可以使用 googlemapapi 得到这个，即首先我从这个地址获取纬度和经度，并使用这个纬度和经度以及谷歌时区 api 密钥我在 javascript 中获取时区。
我想要纯 php 代码中的时区。我可以吗 ？

我正在尝试创建一个聊天应用程序,我的用户将收到通知.通知量如此之高,如果我为每个通知创建一个条目,那么它将填满所有地方,所以我想到应用BigTextView通知或堆栈通知.
我在下面写了一段代码:
NotificationManager notificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
if(listMessage.size() <= 5)
listMessage.add(messagetype + ":" + msg);
else
{
listMessage.remove(4);
listMessage.add(messagetype + ":" + msg);
}
Intent notificationIntent = new Intent(this, GcmActivity.class);
notificationIntent.putExtra("title", messagetype);
notificationIntent.putExtra("message", msg);
PendingIntent intent = PendingIntent.getActivity(this, 0,notificationIntent, 0);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
NotificationCompat.Builder mBuilder;
mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("My MESSENGER")
.setStyle(new NotificationCompat.BigTextStyle()
.bigText("MESSAGES"))
.setContentText(msg)
.setAutoCancel(true)
.setLights(Color.WHITE, 1000, 5000)
.setDefaults(Notification.DEFAULT_VIBRATE |
Notification.DEFAULT_SOUND | Notification.DEFAULT_LIGHTS)
.setContentIntent(intent);
NotificationCompat.InboxStyle inboxStyle =
new NotificationCompat.InboxStyle();
inboxStyle.setBigContentTitle("MESSAGES");
for(int j= 0;j < listMessage.size();j++)
{
inboxStyle.addLine(listMessage.get(j));
} …
