iOS json数据传输问题

Question

正确的数据为：{"display":["images\/background1\/glass\/display\/1-3-001.png","images\/background1\/glass\/display\/1-3-002.png","images\/background1\/glass\/display\/1-3-003.png"],select":["images\/background1\/glass\/select\/1-4-001.png","images\/background1\/glass\/select\/1-4-002.png","images\/background1\/glass\/select\/1-4-003.png"]}
但是有时候后面的一些字符会被截断，变成{"display":["images\/background1\/glass\/display\/1-3-001.png","images\/background1\/glass\/display\/1-3-002.png","images\/background1\/glass\/display\/1-3-003.png"],select":["images\/background1\/glass\/select\/1-4-001.png","images\/background1\/glass\/select\/1-4-002.png","images\/background
当数据量更大的时候传输完整数据成功的概率就更低。。请问这是怎么回事？iOSJSON

这些数据不算大啊，是不是代码有什么问题，http传输完毕了么？
