封装UILable和UITextField

建一个类LTview

重写初始化过程

- (instancetype)initWithFrame:(CGRect )frame{

self = [super initWithFrame:frame];

if(self){

[self creatLabel:frame];

[self creatTextField:frame];

}

reture self;

}

- creatLabel:(CGRect)frame{

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake:(0, 0, frame.size.width / 3, frame.size.height);

[self addSubview:label];  //将label添加到LTview的对象上

[label release];

}

- creatTextField:(CGRect)frame{

UITextField *field = [[UITextField alloc] initWithFrame:CGRectMake:(frame.size.width / 3, 0, frame.size.width * 2 / 3, frame.size.height)];

[self addSubview:field];

[field release];

}
