Collection __NSArrayM: 0xxxxxxx was mutated while being enumerated.

在遍历时，又操作NSArray或者NSMutableArray，会出现这个错误。

NSMutableArray * array = xxx;

for (NSDictionary * dic in array) {

[array removeObject:dic];

}

改为如下即可：

NSMutableArray * array = xxx;

NSArray * tempArray = [NSArray arrayWithArray: array];

for (NSDictionary * dic in arrayTemp) {

[array removeObject:dic];

}
