IOS开发之判断两个数组中数据是否相同实例详解

NSArray *array1 = [NSArray arrayWithObjects:@"a", @"b", @"c", nil nil];

NSArray *array2 = [NSArray arrayWithObjects:@"b", @"a", @"c", nil nil];

boolbol =false;

//创建俩新的数组

NSMutableArray *oldArr = [NSMutableArray arrayWithArray:array1];

NSMutableArray *newArr = [NSMutableArray arrayWithArray:array2];

//对数组1排序。

[oldArr sortUsingComparator:^NSComparisonResult(id obj1, id obj2){

  returnobj1 > obj2;

}];

////上个排序好像不起作用，应采用下面这个

[oldArr sortUsingComparator:^NSComparisonResult(id obj1, id obj2){return[obj1 localizedStandardCompare: obj2];}];

//对数组2排序。

[newArr sortUsingComparator:^NSComparisonResult(id obj1, id obj2){

   returnobj1 > obj2;

   }];

////上个排序好像不起作用，应采用下面这个

[newArr sortUsingComparator:^NSComparisonResult(id obj1, id obj2){return[obj1 localizedStandardCompare: obj2];}];

if(newArr.count == oldArr.count) {

  bol =true;

  for(int16_t i = 0; i < oldArr.count; i++) {

    id c1 = [oldArr objectAtIndex:i];

    id newc = [newArr objectAtIndex:i];

    if(![newc isEqualToString:c1];) {

     bol =false;

     break;

     }

   }

 }

if(bol) { 

  NSLog(@"两个数组的内容相同！"); 

} 

else{ 

  NSLog(@"两个数组的内容不相同！"); 

}
