Because of the project requirements, I have customized the UITableViewCell. Simulator debugging has been no problem very stable, when I want to debug the real machine to find that the program will crash and crash into the main function there, really let me baffled, and there is no clue. So I used the most stupid way 1.1 points of tracking, and finally decided to be in the cellfor ... After the function alloc Tableviewcell, I used the masonry to position the cell's control and then returned to the program and ran without knowing where the crash was. It is normal to remove masonry constraints. But I really do not understand why, finally found that I did not choose to develop the project in the team, is really two irrelevant place. Do not know why, but set up the team after the problem solved.
