IOS-determine the current device model of the user (iPhone model)
Judgment Method: When we adapt to multiple models, we usually need to consider the model of the User device, and then determine the size of the control or Image Based on the width, height, and resolution of the User device. So how do I know the model of the user's device? I personally use (the following method) 1 [[UIScreen mainScreen] bounds]; To obtain the bounds of the home screen, A familiar friend will surely think of the CGRect struct as soon as he sees bound or frame, and bounds is also a variable of this struct, among which the CGRect member has a CGSize (also a struct ), CGSize members include width and height, so now we can get the width and height of the main screen. Then we can know the specific models used by users based on the data below: width * High portrait width * height iPhone4: 320*480 iPhone5: 320*568 iPhone6: 375*667 iPhone6Plus: 414*736 data can be found in the sample code in the complete guide for IOS device design: Here a category UIDevice + IPho of UIDevice is created.
