將需要的傳的數(shù)組轉(zhuǎn)化成NSSet集合。

NSArray * arr1 = @[@"11",@"22"];
NSArray * arr2 = @[@"33",@"44"];
//兩個數(shù)組合并成一個數(shù)組
NSArray * zongArr = [arr1 arrayByAddingObjectsFromArray:arr2];
NSLog(@"zongArr = %@",zongArr);
NSSet * arrSet = [NSSet setWithArray:zongArr];

打印結(jié)果：
zongArr = (
    11,
    22,
    33,
    44
)
