在開發(fā)中，可能會遇到一個頁面好多textField或者textView的情況，鍵盤彈出時，會遮蓋下面的輸入框，使我們看不到內(nèi)容，以往我都是測量當前textfield在屏幕中的位置，current_y,及current_height，計算當前鍵盤的height是否比當前textfield的下方位置要高，如果高的話，則需調(diào)整self.view整體位置。詳見文章鏈接? http://m.itdecent.cn/p/82881c4659b8? 這個方法比較麻煩，現(xiàn)在我們引入IQKeyboardManger就能輕松解決我們的問題
1 . 首先導入IQKeyboardManager框架
$? pod 'IQKeyboardManager'
2.安裝完成之后，引入文件，最好放在項目的PrefixHeader文件中
#import "IQKeyboardManager.h"
3.創(chuàng)建如圖1 的? 幾個textField
輸入文字時，鍵盤會遮擋部分輸入框
? ? UITextField * tf = [[UITextField alloc]initWithFrame:CGRectMake(100, 100, 200, 60)];
? ? tf.placeholder = @"please input placeholder words.";
? ? UITextField * tf2 = [[UITextField alloc]initWithFrame:CGRectMake(100, 240, 200, 60)];
? ? tf2.placeholder = @"please input placeholder words.";
? ? UITextField* tf3 = [[UITextFieldalloc]initWithFrame:CGRectMake(100,320,200,60)];
? ? tf3.placeholder = @"please input placeholder words.";
? ? UITextField* tf4 = [[UITextFieldalloc]initWithFrame:CGRectMake(100,400,200,60)];
? ? tf4.placeholder = @"please input placeholder words.";
? ? UITextField * tf5 = [[UITextField alloc]initWithFrame:CGRectMake(100, 480, 200, 60)];
? ? tf5.placeholder = @"please input placeholder words.";
? ? tf.borderStyle = UITextBorderStyleRoundedRect;
? ? tf2.borderStyle = UITextBorderStyleRoundedRect;
? ? tf3.borderStyle = UITextBorderStyleRoundedRect;
? ? tf4.borderStyle = UITextBorderStyleRoundedRect;
? ? tf5.borderStyle = UITextBorderStyleRoundedRect;
? ? [self.viewaddSubview:tf];
? ? [self.viewaddSubview:tf5];
? ? [self.viewaddSubview:tf2];
? ? [self.viewaddSubview:tf3];
? ? [self.viewaddSubview:tf4];
3. 具體設置如下
//設置IQKeyboardManager
//1 控制自動鍵盤功能啟用與否，默認為YES （只要項目中導入了此框架，不用設置下面代碼，也會自動開啟 )
[IQKeyboardManager sharedManager].enable = YES;
//2? 鍵盤彈出時，點擊背景，鍵盤回收
[IQKeyboardManager sharedManager].shouldResignOnTouchOutside = YES;
//3? 隱藏鍵盤上的toolbar,默認是開啟的
[IQKeyboardManager sharedManager].enableAutoToolbar = NO;
//4? 如果某一個m文本框確實不需要鍵盤上面的toolbar(置空即可)
? ? tf.inputAccessoryView = [[UIView alloc]init];
//5. 如果某個頁面一進來不想讓鍵盤彈出
- (void)viewWillAppear:(BOOL)animated{
? ? [superviewWillAppear:animated];
? ? //關閉自動鍵盤功能
? [IQKeyboardManager sharedManager].enable = YES;
}
- (void)viewWillDisappear:(BOOL)animated{
? ? [super viewWillDisappear:animated];
? //開啟自動鍵盤功能
? [IQKeyboardManager sharedManager].enable = YES;
}
結(jié)果如下，鍵盤不會遮擋輸入框，頁面整體自動上調(diào)，大功告成?。?！
