之前一個項目適配ios7之後,發現原先的UIAlertView無法正常顯示。
後來發現ios7裡面原生態的UIAlertView不支持自定義瞭。
然後就去github上找瞭下。發現瞭一個不錯的第三方庫。和我們之前的使用習慣差不多。
mark一下。
下面給個簡單的示例。
1.導入文件。
將這兩個文件加入我們的工程下。vcD4KPHA+PGJyPgo8L3A+CjxoMT4yLsztvNPNt87EvP48L2gxPgo8cD7U2tDo0qrKudPDVUlBbGVydFZpZXe1xLXYt70szO280823zsS8/qGjPC9wPgo8cD4jaW1wb3J0IA==”CustomIOS7AlertView.h”
並且添加協議。
比如我的.h文件
#import #import "CustomIOS7AlertView.h" @interface ViewController : UIViewController @end
3.添加UIAlertView
先給出.m文件。
#import "ViewController.h" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; // Just a subtle background color [self.view setBackgroundColor:[UIColor colorWithRed:0.8f green:0.8f blue:0.8f alpha:1.0f]]; // A simple button to launch the demo UIButton *launchDialog = [UIButton buttonWithType:UIButtonTypeCustom]; [launchDialog setFrame:CGRectMake(10, 30, self.view.bounds.size.width-20, 50)]; [launchDialog addTarget:self action:@selector(launchDialog:) forControlEvents:UIControlEventTouchDown]; [launchDialog setTitle:@"Launch Dialog" forState:UIControlStateNormal]; [launchDialog setBackgroundColor:[UIColor whiteColor]]; [launchDialog setTitleColor:[UIColor blueColor] forState:UIControlStateNormal]; [launchDialog.layer setBorderWidth:0]; [launchDialog.layer setCornerRadius:5]; [self.view addSubview:launchDialog]; } - (IBAction)launchDialog:(id)sender { // Here we need to pass a full frame CustomIOS7AlertView *alertView = [[CustomIOS7AlertView alloc] init]; // Add some custom content to the alert view [alertView setContainerView:[self createDemoView]]; // Modify the parameters [alertView setButtonTitles:[NSMutableArray arrayWithObjects:@"Close1", @"Close2", @"Close3", nil]]; [alertView setDelegate:self]; // You may use a Block, rather than a delegate. [alertView setOnButtonTouchUpInside:^(CustomIOS7AlertView *alertView, int buttonIndex) { NSLog(@"Block: Button at position %d is clicked on alertView %d.", buttonIndex, [alertView tag]); [alertView close]; }]; [alertView setUseMotionEffects:true]; // And launch the dialog [alertView show]; } - (void)customIOS7dialogButtonTouchUpInside: (CustomIOS7AlertView *)alertView clickedButtonAtIndex: (NSInteger)buttonIndex { NSLog(@"Delegate: Button at position %d is clicked on alertView %d.", buttonIndex, [alertView tag]); [alertView close]; } - (UIView *)createDemoView { UIView *demoView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 290, 200)]; UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 270, 180)]; [imageView setImage:[UIImage imageNamed:@"demo"]]; [demoView addSubview:imageView]; return demoView; } @end
這裡,通過一個button綁定彈出UIAlertView。 當然,你也可以在其他條件觸發launchDialog方法。
然後UIAlertView載入自己定義的視圖(createDemoView)。
另外,塊內的setOnButtonTouchUpInside 和 單獨的delegate customIOS7dialogButtonTouchUpInside方法都能響應我們的選擇。
具體選擇哪種方式因人而異。
