After the custom UITableviewcell is set, the real machine debugging will crash. The custom uitableview
Due to project requirements, I have customized uitableviewcell. The simulator remains stable during debugging. When I want to debug a real machine, I find that the program will crash abnormally and crash to the main function, which makes me puzzled, there is no clue. So I used the dumbest way to track 1.1 points, and finally set it to be in cellfor... after the function alloc tableviewcell, I used masonry to constrain the position of the cell control, and then returned to the program to run it again, so I don't know where the crash went. Remove the masonry constraint. But I really don't understand why. I finally found that I didn't select a development team in the project properties. They were really different from each other. I don't know why, but the problem is solved after the team is set.
