NSFileErrorMaximum = 1023,//文件错误最大值
NSValidationErrorMinimum = 1024,//验证误差最小
NSValidationErrorMaximum = 2047,//验证误差最大值
NSFormattingErrorMinimum = 2048,//格式错误最小值
NSFormattingErrorMaximum = 2559,//格式化错误最大值
NSPropertyListReadCorruptError = 3840,//属性列表读取损坏错误

NSPropertyListReadStreamError = 3842,//属性列表读取流错误
NSPropertyListWriteStreamError = 3851,//写入流错误
NSPropertyListErrorMinimum = 3840,//属性列表错误最小值
NSPropertyListErrorMaximum = 4095,//属性列表错误最大值
NSExecutableErrorMinimum = 3584,//可执行错误最小值
NSExecutableNotLoadableError = 3584,//可执行文件不可加载错误
