Terminating app due to uncaught exception 'NSGenericException', reason: '*** Collection <__NSArrayM: 0xb550c30> was mutated while being enumerated.'
数组遍历事件，崩溃
for (MGFriendListModel *deletefriendModel in self.choosefriendListArray) {
if (deletefriendModel.id == model.id) {
MGLog(@"数组名字 %@",deletefriendModel.remarkName);
[self.choosefriendListArray removeObject:deletefriendModel];
} }
解决办法：Block 枚举遍历解决
[self.choosefriendListArray enumerateObjectsUsingBlock:^(MGFriendListModel *deletefriendModel, NSUInteger idx, BOOL * _Nonnull stop) {
if (deletefriendModel.id == model.id) {
MGLog(@"数组名字 %@",deletefriendModel.remarkName);
[self.choosefriendListArray removeObject:deletefriendModel];
}
}];
