我无法在UITableView中查看我的数据，我的UITableViewcell中有四个标签，我试图从我的网络服务中获取数据。在升级到IOS 8之前它曾经工作正常，在IOS 8中工作后，应用程序无法显示数据。我需要指定的另一件事是，当我从网络浏览器插入数据时，我能够看到我的应用程序在UITableView中的记录，当我使用此应用程序插入数据时，我无法显示记录。我发现Web服务和我的数据库没有问题。因为我在URL中输入数据时能够看到数据。以下是代码：
NSHTTPURLResponse *response = nil;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url
cachePolicy:NSURLRequestReturnCacheDataElseLoad
timeoutInterval:30];
// Make synchronous request
urlData = [NSURLConnection sendSynchronousRequest:urlRequest
returningResponse:&response
error:&error];
if ([response statusCode] >= 200 && [response statusCode] < 300)
{
NSString *responseDatatest = [NSJSONSerialization JSONObjectWithData:urlData
options:NSJSONReadingAllowFragments error:&error];
NSLog(@"responseDatatest : %@",responseDatatest);
NSArray *entries = [NSJSONSerialization JSONObjectWithData:[responseDatatest dataUsingEncoding:NSUTF8StringEncoding]
options:0 error:&error];
NSLog(@"Entries : %@", entries);
if(!entries)
{
NSLog(@"Error : %@", error);
}
else{
for (NSDictionary *entry in entries) {
projectNames = [entries valueForKey:@"NM_PROJECT"];
taskNames = [entries valueForKey:@"TASk_NAME"];
subtaskNames = [entries valueForKey:@"SUBTASK_NAME"];
timesheetid = [entries valueForKey:@"ID_TIMESHEET_DTLS"];
projId = [entries valueForKey:@"ID_PROJECT"];
taskId = [entries valueForKey:@"ID_TASK"];
subtaskId = [entries valueForKey:@"ID_SUB_TASK"];
totalhours = [entries valueForKey:@"No_Hours"];
approve = [entries valueForKey:@"FL_APPROVE"];
leaves = [entries valueForKey:@"NM_LEAVE"];
}
NSInteger sumArray = [[totalhours valueForKeyPath:@"@sum.integerValue"] floatValue];
NSInteger approved = [[approve valueForKeyPath:@"@sum.integerValue"] intValue];
NSLog(@"sumArray : %f", [[totalhours valueForKeyPath:@"@sum.integerValue"] floatValue]);
NSLog(@"approve : %ld", approved);
NSLog(@"subtask : %@", subtaskNames);
}
} else {
