iOS removes duplicate model data from an array

    // Remove model repetition    in array  for 0; i < Self.selectedModelArray.count; i++) {        for (Nsinteger j = i+1; j < Self.selectedModelArray.count; J + + ) {            
    *tempmodel = Self.selectedmodelarray[i];             *model = Self.selectedmodelarray[j];             if ([Tempmodel.assistantid isEqualToString:model.assistantId]) {                [Self.selectedmodelarray removeobject: Model];}}    }

Explain:

1.selectedModelArray is an array of data sources;

2. Two-layer cycle to determine the model repetition, because the model address in the array is different, only through the model of the only Mark Assistantid judgment;

3. The same is removed.

4. The loop ends, and the Selectedmodelarray data source array holds the model data without duplicates.
