分类UIView在动画帧后显示不正确

我已将子类别UIView基本上包含UIPickerView和UIToolbar。分类UIView在动画帧后显示不正确

当用户在选取器中选择一个特定的行时，我会在拾取器上添加一个UIImageView。但是，当我将UIView动画到屏幕上时，此图像不可见。如果我没有动画UIView那么它会正确显示。

我显示UIImageView像这样（在UIView）：

- (void)showMailSetupPopover { 

    if (self.popoverMailSetupImageView == nil) { 

     UIImageView *popoverMailSetupImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"popover-mail-setup-addreminder"]]; 
     popoverMailSetupImageView.alpha = 0.0; 
     popoverMailSetupImageView.frame = CGRectMake(8, self.frame.origin.y + 65, popoverMailSetupImageView.bounds.size.width, popoverMailSetupImageView.bounds.size.height); 
     self.popoverMailSetupImageView = popoverMailSetupImageView; 
    } 

    [self addSubview:self.popoverMailSetupImageView]; 

    [UIView animateWithDuration:0.5 animations:^{ 

     self.popoverMailSetupImageView.alpha = 1.0; 

    } completion:^(BOOL finished) {}]; 
}

这是我如何添加UIView到self.view：

RMMessageTypePickerView *messageTypePickerView = [[RMMessageTypePickerView alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height, 320, 260) reminderMessageType:RMReminderMessageTypeText delegate:self]; 

self.messageTypePickerView = messageTypePickerView; 

[self.view addSubview:self.messageTypePickerView]; 

[UIView animateWithDuration:0.2 animations:^{ 

    self.messageTypePickerView.frame = messageTypePickerViewTargetFrame; 
    self.addReminderTableView.frame = addReminderTableViewTargetFrame; 

} completion:^(BOOL finished) { 

    if (firstShow) { 

     [self processSelectedMessageTypeRow:RMReminderMessageTypeText]; 
    } 
}];

[self.view addSubview：self.messageTypePickerView]; - >将其放入动画完成块。 – Petar 2013-03-07 10:38:58

@ pe60t0我认为你完全错了。如果他将在完成块中添加视图，那么视图的动画移动将不可能 – 2013-03-07 11:21:09

@Peter Warbo，你可以在你调用的地方添加代码 - （void）showMailSetupPopover – 2013-03-07 11:25:20

发现了问题，

取代

popoverMailSetupImageView.frame = CGRectMake(8, self.frame.origin.y + 65, popoverMailSetupImageView.bounds.size.width, popoverMailSetupImageView.bounds.size.height);

与

popoverMailSetupImageView.frame = CGRectMake(8, 65, popoverMailSetupImageView.bounds.size.width, popoverMailSetupImageView.bounds.size.height);

self.frame.origin.y是没有必要的。
