iOS 添加的UIButton为什么不起作用
先看两个例子：
第一个例子，代码如下：
-(void) setPersonInfo:(CGFloat)x y:(CGFloat)y heihgt:(CGFloat)height{
CGFloat width = self.view.frame.size.width - 2 * x;
UILabel *labelInfoArea = [[UILabel alloc]initWithFrame:CGRectMake(x, y+10.0, width, height)];
labelInfoArea.backgroundColor = [UIColor clearColor];
[_contentScroll addSubview:labelInfoArea];
//基本信息的标题
UILabel *labelInfoCaption = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, labelInfoArea.frame.size.width * 0.5, 30.0)];
labelInfoCaption.textColor = [UIColor blackColor];
labelInfoCaption.text = @"基本信息";
labelInfoCaption.font = [UIFont systemFontOfSize:16.0];
labelInfoCaption.backgroundColor = [UIColor clearColor];
[labelInfoArea addSubview:labelInfoCaption];
//complete button
if([[NSString stringWithFormat:@"%@",[_personInfo valueForKey:@"is_completed"]] isEqualToString:@"0"]){
UIButton *completeBtn = [UIButton buttonWithType:UIButtonTypeCustom];
completeBtn.layer.borderColor = [[UIColor colorWithRed:161.0/255.0 green:159.0/255.0 blue:160.0/255.0 alpha:1.0] CGColor];
completeBtn.layer.borderWidth = 1.0;
completeBtn.layer.cornerRadius = 5.0;
completeBtn.layer.backgroundColor = [[UIColor colorWithRed:161.0/255.0 green:159.0/255.0 blue:160.0/255.0 alpha:1.0] CGColor];
[completeBtn setTitle:@"我来完善" forState:UIControlStateNormal];
completeBtn.titleLabel.font = [UIFont systemFontOfSize:12.0];
[completeBtn addTarget:self
action:@selector(redirectCompleteDetail)
forControlEvents:UIControlEventTouchUpInside];
[completeBtn setFrame:CGRectMake(self.view.frame.size.width - 80.0, y + 15.0, 60.0, 20.0)];
[_contentScroll addSubview:completeBtn];
}
//基本信息表格
UILabel *labelInfoTable = [[UILabel alloc] initWithFrame:CGRectMake(labelInfoCaption.frame.origin.x, labelInfoCaption.frame.origin.x + labelInfoCaption.frame.size.height, labelInfoArea.frame.size.width, height - 30.0)];
labelInfoTable.backgroundColor = [UIColor lightGrayColor];
labelInfoTable.layer.borderColor = [[UIColor lightGrayColor] CGColor];
labelInfoTable.layer.borderWidth = 1.0;
labelInfoTable.layer.cornerRadius = 10.0;
[labelInfoArea addSubview:labelInfoTable];
CGFloat tableCellHeight = labelInfoTable.frame.size.height / 2;
CGFloat tableCellWidth = labelInfoTable.frame.size.width / 4;
//添加基本信息-年龄
UILabel *labelAge = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, tableCellWidth, tableCellHeight)];
labelAge.backgroundColor = [UIColor whiteColor];
labelAge.text = @"年龄";
labelAge.font = [UIFont systemFontOfSize:14];
labelAge.textAlignment = NSTextAlignmentCenter;
[labelInfoTable addSubview:labelAge];
//添加基本信息-身高
UILabel *labelHeight = [[UILabel alloc] initWithFrame:CGRectMake(labelAge.frame.origin.x + labelAge.frame.size.width, 0.0, labelAge.frame.size.width, labelAge.frame.size.height)];
labelHeight.backgroundColor = [UIColor whiteColor];
labelHeight.text = @"身高";
labelHeight.font = [UIFont systemFontOfSize:14];
labelHeight.textAlignment = NSTextAlignmentCenter;
[labelInfoTable addSubview:labelHeight];
//添加基本信息-体重
UILabel *labelWeight = [[UILabel alloc] initWithFrame:CGRectMake(labelHeight.frame.origin.x + labelHeight.frame.size.width, 0.0, labelHeight.frame.size.width, labelHeight.frame.size.height)];
labelWeight.backgroundColor = [UIColor whiteColor];
labelWeight.text = @"体重";
labelWeight.font = [UIFont systemFontOfSize:14];
labelWeight.textAlignment = NSTextAlignmentCenter;
[labelInfoTable addSubview:labelWeight];
//添加基本信息-性别
UILabel *labelBMI = [[UILabel alloc] initWithFrame:CGRectMake(labelWeight.frame.origin.x + labelWeight.frame.size.width, 0.0, labelHeight.frame.size.width, labelHeight.frame.size.height)];
labelBMI.backgroundColor = [UIColor whiteColor];
labelBMI.text = @"性别";
labelBMI.font = [UIFont systemFontOfSize:14];
labelBMI.textAlignment = NSTextAlignmentCenter;
[labelInfoTable addSubview:labelBMI];
//+++++++++++++++++++
//添加基本信息-年龄值
UILabel *labelAgeValue = [[UILabel alloc] initWithFrame:CGRectMake(0.0, labelInfoTable.frame.size.height / 2, labelInfoTable.frame.size.width / 4, labelInfoTable.frame.size.height / 2)];
labelAgeValue.backgroundColor = [UIColor whiteColor];
labelAgeValue.font = [UIFont systemFontOfSize:14];
if([[NSString stringWithFormat:@"%@",[self.personInfo valueForKey:@"age"]] isEqualToString:@"0"])
{
labelAgeValue.text = @"无";
}
else
{
labelAgeValue.text = [NSString stringWithFormat:@"%@岁",[self.personInfo valueForKey:@"age"]];
}
labelAgeValue.textAlignment = NSTextAlignmentCenter;
[labelInfoTable addSubview:labelAgeValue];
//添加基本信息-身高值
UILabel *labelHeightValue = [[UILabel alloc] initWithFrame:CGRectMake(labelAgeValue.frame.origin.x + labelAgeValue.frame.size.width, labelAgeValue.frame.origin.y, labelAgeValue.frame.size.width, labelAgeValue.frame.size.height)];
labelHeightValue.backgroundColor = [UIColor whiteColor];
labelHeightValue.font = [UIFont systemFontOfSize:14];
if([[NSString stringWithFormat:@"%@",[self.personInfo valueForKey:@"height"]] isEqualToString:@"0"])
{
labelHeightValue.text = @"无";
}
else
{
labelHeightValue.text = [NSString stringWithFormat:@"%@CM",[self.personInfo valueForKey:@"height"]];
}
labelHeightValue.textAlignment = NSTextAlignmentCenter;
[labelInfoTable addSubview:labelHeightValue];
//添加基本信息-体重值
UILabel *labelWeightValue = [[UILabel alloc] initWithFrame:CGRectMake(labelHeightValue.frame.origin.x + labelHeightValue.frame.size.width, labelHeightValue.frame.origin.y, labelHeightValue.frame.size.width, labelHeightValue.frame.size.height)];
labelWeightValue.backgroundColor = [UIColor whiteColor];
labelWeightValue.font = [UIFont systemFontOfSize:14];
if([[NSString stringWithFormat:@"%@",[self.personInfo valueForKey:@"weight"]] isEqualToString:@"0"])
{
labelWeightValue.text = @"无";
}
else
{
labelWeightValue.text = [NSString stringWithFormat:@"%@KG",[self.personInfo valueForKey:@"weight"]];
}
labelWeightValue.textAlignment = NSTextAlignmentCenter;
[labelInfoTable addSubview:labelWeightValue];
//添加基本信息-性别
UILabel *labelBMIValue = [[UILabel alloc] initWithFrame:CGRectMake(labelWeightValue.frame.origin.x + labelWeightValue.frame.size.width, labelWeightValue.frame.origin.y, labelWeightValue.frame.size.width, labelWeightValue.frame.size.height)];
labelBMIValue.backgroundColor = [UIColor whiteColor];
labelBMIValue.font = [UIFont systemFontOfSize:14];
if([[NSString stringWithFormat:@"%@",[self.personInfo valueForKey:@"sex"]] isEqualToString:@"0"])
{
labelBMIValue.text = @"无";
}
else
{
labelBMIValue.text = [NSString stringWithFormat:@"%@",[self.personInfo valueForKey:@"sex"]];
}
//
// if([[NSString stringWithFormat:@"%@",[self.personInfo valueForKey:@"bmi"]] isEqualToString:@"0"])
// {
// labelBMIValue.text = @"无";
// }
// else
// {
// labelBMIValue.text = [NSString stringWithFormat:@"%@KG",[self.personInfo valueForKey:@"bmi"]];
// }
labelBMIValue.textAlignment = NSTextAlignmentCenter;
[labelInfoTable addSubview:labelBMIValue];
//++++++++++++++++
//横轴分割线-第一根
UILabel *vfirstLine = [[UILabel alloc] initWithFrame:CGRectMake(0.0, tableCellHeight + labelAge.frame.origin.y, labelInfoTable.frame.size.width, 1.0)];
vfirstLine.backgroundColor = [UIColor lightGrayColor];
[labelInfoTable addSubview:vfirstLine];
//竖轴分割线-第一根
UILabel *firstLine = [[UILabel alloc] initWithFrame:CGRectMake(labelAge.frame.origin.x + labelAge.frame.size.width, 0.0, 1.0, labelInfoTable.frame.size.height)];

thridLine.backgroundColor = [UIColor lightGrayColor];
[labelInfoTable addSubview:thridLine];
}第二个例子，代码如下：
-(void) setPersonInfo:(CGFloat)x y:(CGFloat)y heihgt:(CGFloat)height{
CGFloat width = self.view.frame.size.width - 2 * x;

[_contentScroll addSubview:labelInfoArea];

labelInfoCaption.font = [UIFont systemFontOfSize:16.0];
labelInfoCaption.backgroundColor = [UIColor clearColor];
[labelInfoArea addSubview:labelInfoCaption];

//完善信息的按钮
-(void) setupComplateButton:(CGFloat) y{
//基本信息的完善按钮
if([[NSString stringWithFormat:@"%@",[_personInfo valueForKey:@"is_completed"]] isEqualToString:@"0"]){
UIButton *completeBtn = [UIButton buttonWithType:UIButtonTypeCustom];
completeBtn.layer.borderColor = [[UIColor colorWithRed:161.0/255.0 green:159.0/255.0 blue:160.0/255.0 alpha:1.0] CGColor];
completeBtn.layer.borderWidth = 1.0;
completeBtn.layer.cornerRadius = 5.0;
completeBtn.layer.backgroundColor = [[UIColor colorWithRed:161.0/255.0 green:159.0/255.0 blue:160.0/255.0 alpha:1.0] CGColor];
[completeBtn setTitle:@"我来完善" forState:UIControlStateNormal];
completeBtn.titleLabel.font = [UIFont systemFontOfSize:12.0];
[completeBtn addTarget:self
action:@selector(redirectCompleteDetail)
forControlEvents:UIControlEventTouchUpInside];
[completeBtn setFrame:CGRectMake(self.view.frame.size.width - 80.0, y + 15.0, 60.0, 20.0)];
[_contentScroll addSubview:completeBtn];
}
}第一个例子，我将按钮直接放在了里面。导致我后面做操作的时候，似乎将重新添加了一个层，将我的UIbutton按钮覆盖掉了。导致不起作用。第二个例子是我在这个项目的解决方案，直接分开，我将UIButton直接作为最后的层添加到view上，这样就不会覆盖掉，结果达到了我想要的效果。
