@property (retain, nonatomic) IBOutlet UITableView *bluetoothDeviceTable;
@synthesize lblError;为什么@synthesize
ViewController.mm
- (void)viewDidUnload - (void)dealloc
Assertion failure in -[UITableView dequeueReusableCellWithIdentifier:forIndexPath:], /SourceCache/UIKit/UIKit-3347.44.2/UITableView.m:6245
2015-08-10 14:15:14.856 BBPOS[6116:1199091] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'unable to dequeue a cell with identifier DeviceList - must register a nib or a class for the identifier or connect a prototype cell in a storyboard’
使用了第三方一个库，结果，出现，iOS Undefined symbols for architecture armv7 std::basic_string<char, std::char_traits<char>
注意：不是修改Build Setting里面的设置，而是添加一个libstdc++.dylib, 搞定！
