output varies from simulator to device

i have some icons placed at a particular position in the .xib file and they are being seen exactly at the same place while seen in simulator.. But, when i put it on the device,the images seems to come too close to each oth开发者_运维知识库er and they are looking crippled or overlapped ... is there anything i can do to solve this problem... ? Thank you

Are your image files saved with 72 dpi? I have seen Interface Builder occasionally having problems with files that do not have 72 dpi (even though this value is almost meaningless for pixel-based display).

To check, open the images in Preview.app, choose Tools -> Adjust Size and check the dpi value. If it isn't 72, correct it but DO NOT change the pixel dimensions. Just the dpi value.
