在xcode编译的时候,提示了code will never be executed这个警告。百度了一下,大体的意思是,该代码永远不会执行的意思。
比如:
- (void)setMyStyle:(AddressBookStyle)myStyle {
_myStyle = myStyle;
return;
//>>>>>珠珠<<<<<<因为有return 走不到 if里面,所以注视了--0726
if (myStyle == AddressBookStyleNoneFriend) {
_topView.hidden = NO;
_midView.hidden = NO;
_defaultView.hidden = YES;
_myHeightNum.constant = 113;
_becameCodeBtn.hidden = YES;
[_addSomeOneBtn setTitle:@"邀请好友加入" forState:UIControlStateNormal];
_btnTopLabe.text = @"您的通讯录没有成员可加入项目";
self.frame = CGRectMake(0, 0, kScreenWidth, 180);
}else if(myStyle == AddressBookStyleHaveFriend) {
_topView.hidden = NO;
_midView.hidden = NO;
_defaultView.hidden = YES;
_myHeightNum.constant = 153;
_becameCodeBtn.hidden = NO;
[_addSomeOneBtn setTitle:@"从通讯录中导入" forState:UIControlStateNormal];
_btnTopLabe.text = @"请导入讨论组成员";
self.frame = CGRectMake(0, 0, kScreenWidth, 220);
}else if (myStyle == AddressBookStyleDefault) {
_topView.hidden = YES;
_midView.hidden = YES;
_defaultView.hidden = NO;
self.frame = CGRectMake(0, 0, kScreenWidth, 95);
}
}
return;
//>>>>>珠珠<<<<<<因为有return 走不到 if里面,所以注视了--0726
if (myStyle == AddressBookStyleNoneFriend) {
_topView.hidden = NO;
_midView.hidden = NO;
_defaultView.hidden = YES;
_myHeightNum.constant = 113;
_becameCodeBtn.hidden = YES;
[_addSomeOneBtn setTitle:@"邀请好友加入" forState:UIControlStateNormal];
_btnTopLabe.text = @"您的通讯录没有成员可加入项目";
self.frame = CGRectMake(0, 0, kScreenWidth, 180);
}else if(myStyle == AddressBookStyleHaveFriend) {
_topView.hidden = NO;
_midView.hidden = NO;
_defaultView.hidden = YES;
_myHeightNum.constant = 153;
_becameCodeBtn.hidden = NO;
[_addSomeOneBtn setTitle:@"从通讯录中导入" forState:UIControlStateNormal];
_btnTopLabe.text = @"请导入讨论组成员";
self.frame = CGRectMake(0, 0, kScreenWidth, 220);
}else if (myStyle == AddressBookStyleDefault) {
_topView.hidden = YES;
_midView.hidden = YES;
_defaultView.hidden = NO;
self.frame = CGRectMake(0, 0, kScreenWidth, 95);
}
}
因为有return,所以,if里面的永远都走不到。
