I'm my program i'm loading a fairly large MutableDictionray and I would like to use a UIProgressBar. Does anyone have a suggestion of how to determine the loading time to make this work?
How to take these parameters the same way this function does?
1:error: property 'myBoolVariableName' with 'retain' attribute must be of object type
-dictionaryWithContentsOfFile:.. Passing NSInteger variable to NSMutableDictionary or NSMutableArray
- First, rather this forcing the user to wait for a long load, consider changing your data storage. does removefromsuperview releases the objects of scrollview?Core Data may be a better tool for this than a very large Dictionary.. Renew Provisioning Profile
- Read the file into an
-[NSFileHandle readDataOfLength:]in rule to chunk it so you must update your progress bar. [iPhone SDK] [Newbie] UITextView textViewDidChange will not be called?You must did this on a background thread and post notifications or call a delegate method on the main thread to let the progress indicator update.. conflict between JQuery slider and iui (iphone)
- You may want to experiment with
-readInBackgroundAndNotify. I don't know the buffer-size off the top of my head for the iPhone, although it may be small enough to receive notifications back at reasonable intervals, and it should remove the need to manage your own background thread..
- Once you've read the data into an
NSData, parse it using
+[NSPropertyListSerialization propertyListFromData:mutabilityOption:format:errorDescription:. This should hopefully be fast enough not to hang anything, although if it's too slow, you must did this on a background thread and make it part of your last progress bar update. Some experimentation may be required to receive the UI smooth here..
