initWithFrame and Initwithcoder

When we write a program that does not use the nib file (XIB), but instead uses code to generate the control to the image when it is called initWithFrame to initialize

-(ID) initWithFrame: (cgrect) frame

{

if (self=[SuperInitwithframe:frame]) {

Initialize Code

}

return self;

}

When you load an instance of an object from the nib using the nib file, the instance object is initialized with Initwithcoder .

-(ID) Initwithcoder: (nscoder*) coder

{

if (self=[SuperInitwithcoder:coder]) {

Initialize Code

}

return self;

}

So when writing a control, pay attention to the different invocations of these two ways
