iphone - MKMapView not showing on device -

-

I have a little problem and I do not know why.

Woking my map view is okay in the simulator, but on the real device, I only see the gray area and the pin on the "Google" logo. It seems that you can not images be loaded, so that when you look closer and wait for you to draw near to see the intersection.

Here is my code, I can help #import "Maps.h" #import "RootViewController.h" @implementation AddressAnnotation coordination @synthesize ; - (NSString *) subtitles {return @ "327 Anzac Parade, Wodonga, Victoria, Australia"; } - (NSString *) title {@ @ Blazing Stump @; } - (id) initWithCoordinate: (CLLocationCoordinate2D) c {coordinate = c; NSLog (@ "% f,% f", c.latitude, clongitude); Self return; } @end @implementation Maps - (CLLocationCoordinate2D) addressLocation {NSString * locationString = [NSString stringWithContentsOfURL: [NSURL URLWithString: @ "http://maps.google.com/maps/geo?q=327%20Anzac%20Parade,%20Wodonga ,% 20 Victoria,% 20 Australia and Output = CSV & KEY = ABQAAAGS 2Z FxIUBFPLPGMGbTXE 17-T8X3x3AGRA9NUFATA 8MRRMYLMMPTOSGGJXAATAJ 7T-RV "] Encoding: NSUFF 8 string encoding error: zero] ; NSArray * listItems = [locationString Components EspressedBestString: @ ","]; Double latitude = -36.139226; Double longitude = 146.911454; If ([list is calculated]> gt; = 4 & amp; amp; [[listItems objectAtIndex: 0] isEqualToString: @ "200"]) {latitude = [[listItems objectAtIndex: 2] double value]; Longitude = [[List item autandex: 3] double value]; } Other {// some error} CLLocationCoordinate2D location; place. Latitude = latitude; place.

Did you ensure that the map digit has been determined? Make sure that you add links to the header and mapkit.delagte = self on the view;

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment. Gatefolder path (environment specialfolder personal), "mydb.db3"); // The following line will be called coolestation, where is the database, // to make it if it does not exist, and call a delegate that creates the necessary tables (only when the database file was newly created //) CSConfig.SetDB (DbName, true, () => {CSDatabase.ExecuteNonQuery ("Subscriber Integer Primary Key Attribute, Name Text (50) No, Number, Date First Text (30)");); There is no difference when I try to use the methods of CSConfig and when I cscfif If I try to pass 3 aggregates to STDB (3) then I get the invalid ...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
