OC Set/get method

Create a new "Cocoa Touch Class" file named people

People.h Write

@interface People:nsobject@property    int Age ; @end

PEOPLE.M write (in fact automatically generated)

@implementation people @end

Use occasions:

intMainintargcChar*argv[]) {People*p=[[People alloc]init]; P.age=Ten;//using the Set method directlyNSLog (@"Age %d\n", p.age);//using the Get method directly[P Setage: -];//calling the Set methodNSLog (@"Age %d\n", [P age]);//call the Get method    inttest; Test=1; NSLog (@"Age %d\n", test); }

Manual Write Set/get method

The Set/get method can be generated automatically by @property in the example above, and we can also write the Set/get method manually.

Modify People.h

@interface people:nsobject{    int  _age;} @property   int age ; @end

Modify PEOPLE.M

@implementation People-(void) Setage: (int) age{    NSLog (@ "setage" );    _age= Age;} -(int) age{    NSLog (@ "getAge");     return _age;} @end

Through the personality, and then execute the program, found that we manually write the Set/get method of the output of the log.
