####Xcode工程创建多个target

CustomPopAnimation中，通过复制Target； 使用宏定义生成不同的Target， OTHER_CFLAGS = -DUSE_方案一;

####Runtime+KVC

NSLog(@"---%@", self.interactivePopGestureRecognizer);

unsigned int count = 0;

// 获取类成员变量列表，count为类成员数量
Ivar *var = class_copyIvarList([UIGestureRecognizer class], &count);
for (int i = 0; i < count; i++) {
    Ivar _var = *(var+i);
    NSLog(@"%s", ivar_getTypeEncoding(_var));
    NSLog(@"%s", ivar_getName(_var));
}

NSMutableArray *_targets = [gesture valueForKey:@"_targets"];
NSLog(@"%@", _targets);
NSLog(@"%@", _targets[0]);
