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*/
