需要的控件，声明为属性，然后重写setter方法

- (UIImageView *)filterView

{

if (_filterView ==nil) {

_filterView = [[UIImageViewalloc] initWithFrame:CGRectMake(0.0f,50.0f, self.view.frame.size.width,200.0f)];

_filterView.userInteractionEnabled =YES;

_filterView.contentMode =UIViewContentModeScaleAspectFit;

}

return_filterView;

}

- (UILabel *)filterLabel

{

if (_filterLabel ==nil) {

_filterLabel = [[UILabelalloc] initWithFrame:CGRectMake(0.0f,300.0f, self.view.frame.size.width,25.0f)];

_filterLabel.backgroundColor = [UIColorclearColor];

_filterLabel.textColor = [UIColororangeColor];

_filterLabel.textAlignment =NSTextAlignmentCenter;

}

return_filterLabel;

}

应用的时候，只需要简单的两句代码

self.filterView.image = [UIImageimageNamed:@"bianjitupian.png"];

[self.viewaddSubview:self.filterView];

self.filterLabel.text =@"原图";

[self.viewaddSubview:self.filterLabel];

完美～＝～
