试图调试过去10个小时的崩溃,最后我简化为这段代码:
NSError *error = nil; NSData *data = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"payload" ofType:@"txt"]]; id obj = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];
使用NSZombieEnabled,这会使应用程序在第三行(解析发生时)崩溃,并记录:
*** -[CFString retain]: message sent to deallocated instance 0x758afa0
payload.txt的内容是:

这只是一个2个字典的数组.我不知道是什么导致这个崩溃/这个JSON有什么问题.
UPDATE删除“is_subscribed”:数组中的第一个对象中的0将消除崩溃.
