nsurlconnection - Does the iPhone / iPod touch cache data also on disk, or only in memory? -

-

I'm not sure, but I think I was reading some time ago that anything on the iPhone / iPod touch disc Does not cache. Cash only in memory so the cache is not persistent when the app ends. This will bring data back to the net after the relaunching the application. is it true?

You can use the iPhone simulator, open the terminal or finder, and `library / application support / IPhone simulator / user / application / then any directory that you have in your application must be opened.

You will see a document directory, library and tmp directory.

I have never seen whether UIWebView is caching anything but I know that core data

If you exclude your data using CF networks, then I believe that this will allow you to tmp or Keeps the document if you wish.

TMP will not be backed up with the iTunes sync process, but documents , hence will not use documents temporary cache Otherwise you will simply waste the space and slow down the sync backup.

In addition to the removal of the application entirely by the springboard or the total device memory being deleted, the delivery of documents may be anything, including the app upgrade.

In fact, directory directories in the Library directory are caches, webkit / local storage, and preferences so it can suggest some or the other.

The application can not be written to the bundle directory or bad things.

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
