iPhone-iPad Development Tips :: N-FAQ; Aasim Naseem, February 5, 2011March 12, 2024 Hello Everyone; Hope weekend is going good;Today’s menu is really simple; I will give you some tips regarding iPhone application development; I used them recently so want to share with you people; Here they are;1. Screen Resolution;iPhones are available in different screen resolutions; It is in 320×480 and the iPhone 4 screen resolution is 640×960. Same in caes of iPad; Currently it is 1024×768 and iPad 2 likely to have 2048×1536 screen resolution; So we need to care about this while playing with layouts; Here is a code to determine screen size;CGRect currentScreen = [[UIScreen mainScreen] bounds]; currentScreen.size.width will return the width of screen; currentScreen.size.height will return height of screen;Note: If you rotate your screen to landscape, then height will become width and vise versa;2. Device Type;Following piece of code will tell you whether your application is running on iPhone or iPad;UIDevice* currentDevice = [UIDevice currentDevice]; if(currentDevice.userInterfaceIdiom == UIUserInterfaceIdiomPad) { NSLog(@"oh its iPad"); }else{ NSLog(@"This is iPhone"); }3. Current iOS version; UIDevice* currentDevice = [UIDevice currentDevice]; float systemVersion = [currentDevice.systemVersion floatValue]; This float value will tell you the current iOS version of device;4. Current Orientation;It is common to have different layout for single application in portrait and/or landscap view; In case of iPad it become more significant; Following method will tell you the current orientation of user’s device; -(int) currentLayout{ if (([[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationPortrait ||[[UIApplication sharedApplication] statusBarOrientation] == UIDeviceOrientationPortraitUpsideDown)) // do something for portrait view;else // do something for landscape view; } Thats all; Share Every bit of knowledge you have; Happy Development;– This post belongs to N-FAQ category where i post anything i learn new during my work; N-FAQ = Not-FAQ;Aasim NaseemI’m an engineer by profession, a blogger and a photojournalist by hobby.
