iphone - memory leak when JPEG, not when PNG -

-

my application aims @ saving user photos in pdf file in order send file email. produce small size pdf, want compress images in jpeg. when draw jpeg pdf context, pdf file indeed smaller when use png, use of jpeg leaks.

for debugging added jpeg , png file project.

the following call leaks :

uiimage * destimage = [uiimage imagenamed:@"image.jpg"]; [destimage drawinrect:drawingframe];

whereas 1 not :

uiimage * destimage = [uiimage imagenamed:@"image.png"]; [destimage drawinrect:drawingframe];

is there i'm missing ? know issue ?

i'm thinking workaround consist in using png representations of images , set specific compression option pdf generate, did not find in pdf generation sdk.

do have idea ? in advance.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
