tableViewRowData:], /SourceCache/UIKit_Sim/UIKit-2903.23/UITableViewRowData.m:578 错误

Assertion failure in -[UISectionRowData refreshWithSection:tableView:tableViewRowData:], /SourceCache/UIKit_Sim/UIKit-2903.23/UITableViewRowData.m:578

libc++abi.dylib: terminate_handler unexpectedly threw an exception

这个错误的原因是在计算tableview的高度是出错,

对现实的图片UIImage计算高度,但是此时image为nil,做了200/image.size.height这个操作

导致height += 200/image.size.height,这个计算后,height为NaN,之后报这个错误,

keychain错误:Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Couldn't add the Keychain Item.'

KeyChain内部以kSecAttrAccount 与kSecAttrService作为唯一钥匙串标识,
