iOS以编程方式将左图像添加到Xcode中的UITextField？
**
1）我想要一个带有White Background color的UIview ，在View我添加了4 Textfield's ？
2）我想在View中的4 different textfields的left side添加4 different images ，具有以下属性？
视图属性 i） corner Radius — 5 ii） Border Color —- light Gray Color
3）如何在image和Placeholder Text Textfields Placeholder Text之间添加Space ，如下图所示，还为all textfields具有light gray color Placeholder Text Textfields add layer ？
我怎么能实现这个????
视图结合Textfields和图像这样
UIImageView *imgforLeft=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 25, 25)]; // Set frame as per space required around icon [imgforLeft setImage:[UIImage imageNamed:@"yourImagename.png"]]; [imgforLeft setContentMode:UIViewContentModeCenter];// Set content mode centre or fit self. yourTextfield.leftView=imgforLeft; self. yourTextfield.leftViewMode=UITextFieldViewModeAlways;
选择-2
// short answer with out self. yourTextfield.leftViewMode = UITextFieldViewModeAlways; self. yourTextfield.leftView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yourImagename.png"]];
迅速
self. yourTextfield.leftViewMode = UITextFieldViewMode.Always self. yourTextfield.leftView = UIImageView(image: UIImage(named: "yourImagename.png"))
更新
对于TextField1
UIImageView *imgforLeft1=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 25, 25)]; // Set frame as per space required around icon [imgforLeft1 setImage:[UIImage imageNamed:@"yourImagename1.png"]]; [imgforLeft1 setContentMode:UIViewContentModeCenter];// Set content mode centre or fit self. yourTextfield1.leftView=imgforLeft1; self. yourTextfield1.leftViewMode=UITextFieldViewModeAlways; self. yourTextfield1.layer.sublayerTransform = CATransform3DMakeTranslation(30, 0, 0);
对于TextField2
UIImageView *imgforLeft2=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 25, 25)]; // Set frame as per space required around icon [imgforLeft2 setImage:[UIImage imageNamed:@"yourImagename2.png"]]; [imgforLeft1 setContentMode:UIViewContentModeCenter];// Set content mode centre or fit self. yourTextfield2.leftView=imgforLeft1; self. yourTextfield2.leftViewMode=UITextFieldViewModeAlways; self. yourTextfield2.layer.sublayerTransform = CATransform3DMakeTranslation(30, 0, 0);
对于TextField3
UIImageView *imgforLeft3=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 25, 25)]; // Set frame as per space required around icon [imgforLeft3 setImage:[UIImage imageNamed:@"yourImagename3.png"]]; [imgforLeft3 setContentMode:UIViewContentModeCenter];// Set content mode centre or fit self. yourTextfield3.leftView=imgforLeft1; self. yourTextfield3.leftViewMode=UITextFieldViewModeAlways; self. yourTextfield3.layer.sublayerTransform = CATransform3DMakeTranslation(30, 0, 0);
for TextField4
UIImageView *imgforLeft4=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 25, 25)]; // Set frame as per space required around icon [imgforLeft4 setImage:[UIImage imageNamed:@"yourImagename4.png"]]; [imgforLeft4 setContentMode:UIViewContentModeCenter];// Set content mode centre or fit self. yourTextfield4.leftView=imgforLeft1; self. yourTextfield4.leftViewMode=UITextFieldViewModeAlways; self. yourTextfield4.layer.sublayerTransform = CATransform3DMakeTranslation(30, 0, 0);
UITextfield具有允许设置左视图的属性，您可以将其用于您的目标
喜欢这个
[yourTextfield setLeftView:YOURVIEW];
@property (weak, nonatomic) IBOutlet UITextField *myTextField; UIImageView * myImageView = [[UIImageView alloc]initWithFrame:CGRectMake(0.0f, 0.0f, 15, 15)]; myImageView.image = [UIImage imageNamed:@"myImage"]; [myTextField addSubView:myImageView];
CGRectMake(0.0f, 0.0f, 15, 15)部分允许您指定图像的位置和大小(xPos, yPos, width, height)
