iphone - UIImageView Memory Problem -


i have uiimageview property in view controller set "assign". every time hit button, set image in view new. due way using component, have removefromsuperview , release uiimageview every time change images , re add it. doesn't seem contributing memory problem-- when using existing uiimageview , not releasing memory still goes (but there sizing issues, why recreating it).

for reason, using setimage increase memory usage of app 0.8mb (the size of image). when not set image, memory seems stay relatively constant. ideas why?

[self.pictureview setimage: img]; [self.pictureview setframe: cgrectmake(0,0,[img size].width, [img size].height)]; [img release];

i think leaking uiimageview, , when leak uiimageview, leaking image in it.

it depends how recreate uiimageview. sure releasing old image view before setting new 1 property.

it may best set property retain, because when set new value retain property, releases old instance.
