Custom UITableVIew有时会遇到EXC_BAD_ACCESS
可能原因
1、调用同类型xib所致
在TeamInfoVC类中调用
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"teamInfoVC" owner:self options:nil];
// Grab a pointer to the first object (presumably the custom cell, as that's all the XIB should contain).
ImageCell* cell = [topLevelObjects objectAtIndex:0];
所以在同个xib下,只能调用一次。或者从其他xib中建立custom tableviecell
