提取数组中得相同元素和不同元素

-(NSMutableArray*)deleteSameObject:(NSArray*)array1{

NSMutableArray*dateMutablearray = [@[]mutableCopy];

NSMutableArray*array = [NSMutableArrayarrayWithArray:array1];

for(inti =0; i < array.count; i ++) {

NSString*string = array[i];

NSMutableArray*tempArray = [@[]mutableCopy];

[tempArrayaddObject:string];

for(intj = i+1; j < array.count; j ++) {

NSString*jstring = array[j];

if([stringisEqualToString:jstring]){

[tempArrayaddObject:jstring];

[arrayremoveObjectAtIndex:j];

}

}

[dateMutablearrayaddObject:tempArray];

}

NSLog(@"array:%@",array);//将不同的存入一个数组

NSLog(@"dateMutable:%@",dateMutablearray);//将相同的存入一个数组

returnarray;

}
