ios - SQLite Database Hangs Upon Update -


i've been grinding on problem couple hours , grateful outside input. new ios, objective-c , sqlite , trying execute sqlite update statement. issue ui freezes , seems hang in process within sqlite.

here's code: 

nsstring *docspath = [paths objectatindex:0]; nsstring *path = [docspath stringbyappendingpathcomponent:@"sqlite3database.sqlite"]; sqlite3_instance *db = [sqlite3_instance databasewithpath:path];  [db open];  nsstring *execupdate = [nsstring stringwithformat:@"update listitem set status=%i,message=\"%@\",gpslong=%@, gpslat=%@,lastupdated=datetime('now') userid = %@",[status_picker selectedrowincomponent:0],messagetextfield.text , longitude, latitude,loggedinuserid]; nslog(@"execupdate: %@", execupdate); if (![db executeupdate:execupdate])     nslog(@"data insert failed %@", db.lasterrormessage);

this code executed in ibaction after clicking uibutton, mentioned, ui hung in process. output above code following:

*execupdate: update listitem set status=0,message="",gpslong=44.48916, gpslat=6.28739,lastupdated=datetime('now') userid = 1*

can see how code hung up?

looks issue xcode memory leak. after hours of pounding head agains wall, closing , starting again fixed issue.

are sure process/thread didn't have transaction open against database? cause behavior.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
