Iphone “怎么做？”；pointInside:“；工作

我正在做一些命中测试，遇到了令人困惑的情况

我有两个按钮“favoriteButton”和“shareButton”。以下代码导致“a”和“b”为真，即使按钮不重叠：

CGPoint dunno = CGPointMake(11, 7);

BOOL a = [self.favoriteButton pointInside:dunno withEvent:nil];
BOOL b = [self.shareButton pointInside:dunno withEvent:nil];

为了证明这一点，这里是两个按钮在调用代码时的描述输出

Printing description of _favoriteButton:
<UIButton: 0x5da8c90; frame = (10 6; 37 35); opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x5da8d40>>
Printing description of _shareButton:
<UIButton: 0x5da7150; frame = (46 6; 30 35); opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x5da59b0>>

打印_favorite按钮的说明：
_shareButton的打印说明：

这是怎么回事？我是否误解了输出应该是什么？

这意味着点

CGPoint dunno=CGPointMake（11,7）位于视图内部，因为视图的边界与同一视图的框架不同

A point that is in the receiver’s local coordinate system (bounds).
