遍历NSArray数组的方法

NSArray *array = [NSArray WithObjects:@"one",@"two",nil];

1、索引

for(int i=0;i<[array count];i++){

NSLOG(@"index %d has %@ .", i,  [array objectAtindex i]);

}

2、枚举“王国”

NSEnumerator *enumerator = [array objectEnumerator];

id thingie;

while(thingie = [enumerator nextObject]]){

NSLog(@"i found %@", thingie);

}

3、快速枚举

for(NSString *str in array){

NSLog(@"i found %@",  str);

}
