What is the difference between initializing the nsmutabledictionary in the loop and initializing the nsmutabledictionary outside of the loop, given the two ways iOS gives Nsmutabledictionary a loop assignment? (Resolved)

// mode two initializes the dictionary dictoutside of the for loop, and then initializes the mutable dictionary outside of the loop, adding a key-value pair within the dictionary each time the loop is added, Assigns a dictionary of 10 key-value pairs to an array

nsmutablearray * array2 = [nsmutablearrayarray];

nsmutabledictionary * dict2 = [nsmutabledictionarydictionary];

for (int i =0; i< ; i++) {

nsstring * value = [nsstringstringwithformat:@ "female%04i. JPG ", I];

NSLog (@ "%@____________", array2);

// The difference between the two can be clearly seen from the printed results

// because the dictionary is not understood very deeply: just think of him as a key-value pair, but he can actually save n Key pairs (if you initialize a mutable dictionary every time before setting a key-value pair for a mutable dictionary, there is only one key-value pair for each dictionary)
