构造函数 [英] constructor in objective c

问题描述

HI，
我创建了我的iPhone应用程序，但我有一个问题。
我有一个 classViewController 其中我实现了我的程序。
我必须alloc 3 NSMutableArray 但我不想做在grapich方法。
我的类没有像java这样的构造函数？
非常抱歉我的英语XP

  //我想把它放在类似于构造函数的方法java 
 
 arrayPosition = [[NSMutableArray alloc] init]; 
 currentPositionName = [NSString stringWithFormat：@noPosition]; 
  

解决方案

它叫做 -init ，它有点像这样：

   - （id）init {
 self = [super init]; 
 if（self！= nil）{
 //初始化到这里。 
} 
 return self; 
} 
  

编辑：不要忘记 -dealloc ，tho'。

   - （void）dealloc {
 // release owned objects here 
 [super dealloc]; //很重要。另外，在代码中使用本地语言通常是一个坏的举动，你通常想坚持英语，特别是当在网上寻求帮助等。
 
HI,
I have created my iPhone apps but i have a problem.
I have a classViewController where i have implemented my program.
I must alloc 3 NSMutableArray but i don't want do it in grapich methods.
There isn't a constructor like java for my class?
Thanks so much and sorry for my english XP
// I want put it in a method like constructor java

arrayPosition = [[NSMutableArray alloc] init];
currentPositionName = [NSString stringWithFormat:@"noPosition"];

解决方案
Yes, there is an initializer. It's called -init, and it goes a little something like this:
- (id) init {
  self = [super init];
  if (self != nil) {
    // initializations go here.
  }
  return self;
}
Edit: Don't forget -dealloc, tho'.
- (void)dealloc {
  // release owned objects here
  [super dealloc]; // pretty important.
}
As a side note, using native language in code is generally a bad move, you usually want to stick to English, particularly when asking for help online and the like.
