iOS 判断两个数组元素是否相等

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

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

bool bol = 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){

return obj1 > 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){

return obj1 > 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！");

}
