1.在导航栏添加一个UITextField代码:

self.searchTF = [[UITextFieldalloc]initWithFrame:CGRectMake(50,0, SCREEN_SIZE_WIDTH-100,35)];

self.searchTF.font =MIDDLE_FONT;

self.searchTF.layer.cornerRadius = BUTTON_RADUIS;

self.searchTF.placeholder =@"化妆品";

self.searchTF.tintColor = [UIColorwhiteColor];

self.searchTF.textColor = [UIColorwhiteColor];

self.searchTF.delegate =self;

self.searchTF.backgroundColor =MAIN_THEME_COLOR;

self.navigationItem.titleView =self.searchTF;

NSMutableDictionary *attributes = [NSMutableDictionarydictionary];

//设置富文本对象的颜色

attributes[NSForegroundColorAttributeName] = [UIColorwhiteColor];

//设置UITextField的占位文字

self.searchTF.attributedPlaceholder = [[NSAttributedStringalloc] initWithString:@"手机号"attributes:attributes];

//左侧设置放大镜

self.searchTF.leftViewMode =UITextFieldViewModeAlways;

UIImageView *leftView = [[UIImageViewalloc]initWithFrame:CGRectMake(5, (self.searchTF.bounds.size.height-20)/2,20, 20)];

leftView.image = [UIImageimageNamed:@"temp_fangdajing"];

self.searchTF.leftView = leftView;

2.改变光标颜色

self.searchTF.tintColor = [UIColor whiteColor];

3.改变占位符颜色

NSMutableDictionary *attributes = [NSMutableDictionary dictionary];

// 设置富文本对象的颜色

attributes[NSForegroundColorAttributeName] = [UIColor whiteColor];

// 设置UITextField的占位文字

self.searchTF.attributedPlaceholder = [[NSAttributedString alloc] initWithString:@"手机号" attributes:attributes];

4.设置左侧的站位图放大镜

//左侧设置放大镜

self.searchTF.leftViewMode =UITextFieldViewModeAlways;

UIImageView *leftView = [[UIImageViewalloc]initWithFrame:CGRectMake(5, (self.searchTF.bounds.size.height-20)/2,20, 20)];

leftView.image = [UIImageimageNamed:@"temp_fangdajing"];
