我有一个异步任务,它不会在完成任务时添加百分比.它始终保持在0%0/100
这是我的代码
private class getAppInfo extends AsyncTask<String, String, String> {
/** The system calls this to perform work in a worker thread and
* delivers it the parameters given to AsyncTask.execute() */
ProgressDialog dialog;
@Override
protected void onPreExecute() {
if(showLoading == true){
dialog = new ProgressDialog(SelfHelp.this);
dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
dialog.setMessage("Loading");
dialog.setIndeterminate(true);
dialog.setCancelable(false);
dialog.setMax(100);
dialog.setProgress(100);
dialog.show();
}
}
@Override
protected String doInBackground(String... urls) {
String xml = null;
int count = 0;

int statusCode = statusLine.getStatusCode(); …在尝试执行我的php脚本以向我的iphone发送推送通知后,我收到此错误.
我尝试了一切,没有任何作用.我相信这意味着我ck.pem错了,但我不确定它是key.pem还是cert.pem是错误的.
请帮忙

langChange.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View vi) {

这是方法

Thread 1:EXC_BAD_ACCESS (code=2, address=0xb7ffffc)
在这条线上
[[NSNotificationCenter defaultCenter] postNotificationName:AsyncImageLoadDidFinish
object:target
userInfo:[[userInfo copy] autorelease]];
在AsyncImageView.m文件中.
该错误会停止代码,但如果我继续在调试器中冻结Xcode并将其关闭.我该如何解决这个问题？
发送推送通知后,我希望应用程序在我的收件箱页面上打开,以便用户可以在收件箱中看到新消息.我的AppDelegate中有以下代码
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
[self.tabController setSelectedIndex:2];
}
当我发送推送消息并且电话处于活动状态时,它会在没有警告的情况下直接进入.我知道它应该用我的代码做什么,但有没有办法改变它
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
if(app.isActive == FALSE)
[self.tabController setSelectedIndex:2];
}
对此有任何见解将有很大帮助.谢谢!
我在我的代码中使用ARC,我收到错误
Object 0x781b8e0 of class __NSCFString autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug
它打破的线是
return UIApplicationMain(argc, argv, nil, NSStringFromClass([HomePageAppDelegate class]));
因为我使用ARC,所以不能NSAutoReleasePool像往常那样放置它.我可以使用什么来修复此错误？
我得到的错误是
Terminating app due to uncaught exception 'NSGenericException', reason: '*** Collection <CALayerArray: 0x7c85080> was mutated while being enumerated.'
我理解的NSGenericException是,我在枚举时从数组中删除了一些东西.仍然知道并环顾四周我似乎无法解决我的问题.这是下面的代码.
-(void)tableView(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
//Checks if message has been read. If message has not it updates the unreadMessages array
if ([unreadMessage containsObject:[NSString stringWithFormat:@"m%@",[[storage_array objectAtIndex:indexPath.row] objectForKey:@"id"]]] == TRUE && [[[storage_array objectAtIndex:indexPath.row] objectForKey:@"itemtype"] isEqualToString:@"message"] == TRUE){
//Unread
[unreadMessage removeObject:[NSString stringWithFormat:@"m%@",[[storage_array objectAtIndex:indexPath.row] objectForKey:@"id"]]];
[unreadMessage writeToFile:[self saveUnreadMessages] atomically:YES];
//Read
[readMessage addObject:[NSString stringWithFormat:@"m%@",[[storage_array objectAtIndex:indexPath.row] objectForKey:@"id"]]];
[readMessage writeToFile:[self saveReadMessages] atomically:YES];
[tableView reloadData];
