问如何为15个单词生成10 x 10矩阵

EN

Rather than button use uiimageview, it will be easy as u can implement the sliding effect as well.
U need to implement different classes as Matrix, Plate, Coordinate, BoardManager. Now you have implement the logic arround this class. 
.h matrix class 
int row; int column; NSMutableArray *matrix;

.h plate class
Coordinate *currentCordinate; //center coordinate of the plate.
int presentRow; int presentCol;

.h BoardManager
NSInteger boardMatrixRow;  NSInteger boardMatrixColumn;

.h Coordinate
CGFloat x; CGFloat y;

Now implement the methods and apply your logic of inserting the object into matrix array,assign the coordinates to the plates/image, tagging the image.

As such no tutorial encountered.
