[_btt1 addTarget:self action:@selector(clicked:) forControlEvents:UIControlEventTouchUpInside];
[_btt1 addTarget:self action:@selector(clicked2:) forControlEvents:UIControlEventTouchUpInside];
_btt1中有2个动作。
2013-05-31 10:33:31.300 testTargetAndSelector[6029:c07] actions : (
"clicked:",
"clicked2:"
)
我删除了这样的clicked2动作。
[_btt1 removeTarget:self action:@selector(clicked2:) forControlEvents:UIControlEventTouchUpInside];
但_btt1中没有任何操作。
2013-05-31 10:33:32.731 testTargetAndSelector[6029:c07] actions : (null)
如何从多个操作中删除单个操作?
