崩溃日志:*** Terminating appdue to uncaught exception 'NSGenericException', reason: '*** Collection<__NSArrayM: 0x61800024f7b0> was mutated while being enumerated.'
解决：（例如下）
NSMutableArray * tempArr = xxx;
NSArray * array = [NSArray arrayWithArray: tempArr];
for (NSDictionary * dic in array) {
if (OK){
[tempArr removeObject:dic];
}
}
