iOS数组makeObjectsPerformSelector:

一. 数组的makeObjectsPerformSelector:SEL方法来减少自己写循环代码.
 [self.answerView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)];
 

 1.  makeObjectsPerformSelector:@select（aMethod）

     简介：让数组中的每个元素 都调用 aMethod 

 2.  makeObjectsPerformSelector:@select（aMethod） withObject:oneObject

     简介：让数组中的每个元素 都调用 aMethod  并把 withObject 后边的 oneObject 对象做为参数传给方法aMethod

[array makeObjectsPerformSelector:@selector(setRecurringDelegate:) withObject:self]; /*将检测到的该自动插入的交易插入数据库*/
 
[array makeObjectsPerformSelector:@selector(insertRecursion)];
/*将检测到的该自动插入的交易插入数据库*/
