原因推测
最近公司项目加入 3D touch 功能上线后, 有用户反映他们的机器在点击程序 icon 的时候就直接闪退了, 找了个问题机测试了一下发现是 3D touch 导致的崩溃. 正规渠道购买的机器都没有闪退问题, 某些港版, 日版, 美版机器会出问题, 所以推测是那些机器在购买之前经过越狱或是什么原因, 修改了底层 3D touch 某些属性, 导致本不支持 3D touch 的问题机误以为自己支持该功能导致崩溃.
- 只是推测, 老鸟欢迎指正
初步方案
shortCutItem
由于没有那么多问题机测试, 只有两台, 只能算一个参考方案吧, 反正这两台机器是没问题了.
方案: 限制机型, 只允许 6S 和 9.0以上系统走 3D Touch 方法.
代码:
在AppDelegate.m中
首先导入头文件#import "sys/utsname.h"
pch 文件中定义系统版本号#define IOS_VERSION [[[UIDevice currentDevice] systemVersion] floatValue]
// 获取机型设备号
struct utsname systemInfo;
uname(&systemInfo);
NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
// 如果系统版本大于9.0
if (IOS_VERSION >= 9.0) {
// 如果设备号是 6S 或者 6S PLUS
if ([deviceString isEqualToString:@"iPhone8,1"] || [deviceString isEqualToString:@"iPhone8,2"]) {
// 创建 shortCutItem 的方法
[self createItemsWithIcons];
if (launchOptions[@"UIApplicationLaunchOptionsShortcutItemKey"] == nil) {
return YES;
} else {
return NO;
}
}
}
至此, 打开就闪退的问题在这两台机器上解决了
Preview
在支持 3d touch的视图控制器.m文件中同样导入#import "sys/utsname.h"
在设置traitCollection的方法中同样用上面的判断
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
// 获取设备型号
struct utsname systemInfo;
uname(&systemInfo);
NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
// 判断系统型号
if (IOS_VERSION >= 9.0) {
if ([deviceString isEqualToString:@"iPhone8,1"] || [deviceString isEqualToString:@"iPhone8,2"]) {
if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable) {
[self registerForPreviewingWithDelegate:self sourceView:self.levelCollectionView];
}
}
}
}
如果要预览的 webView 打开了allowsLinkPreview
同样需要重复导入上面的头文件
struct utsname systemInfo;
uname(&systemInfo);
NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
if ([deviceString isEqualToString:@"iPhone8,1"] || [deviceString isEqualToString:@"iPhone8,2"]) {
self.webView.allowsLinkPreview = YES;
}
至此, 这两台问题机器的 3D Touch 崩溃问题解决
设备型号(不完全版)
- (NSString*)deviceVersion {
struct utsname systemInfo;
uname(&systemInfo);
NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
NSLog(@"%@",deviceString);
if ([deviceString isEqualToString:@"iPhone1,1"]) return @"iPhone 1G";
if ([deviceString isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
if ([deviceString isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS";
if ([deviceString isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
if ([deviceString isEqualToString:@"iPhone3,2"]) return @"Verizon iPhone 4";
if ([deviceString isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
if ([deviceString isEqualToString:@"iPhone5,2"]) return @"iPhone 5";
if ([deviceString isEqualToString:@"iPhone6,2"]) return @"iPhone 5S";
if ([deviceString isEqualToString:@"iPhone7,2"]) return @"iPhone 6";
if ([deviceString isEqualToString:@"iPhone7,1"]) return @"iPhone 6 Plus";
if ([deviceString isEqualToString:@"iPhone8,1"]) return @"iPhone 6s";
if ([deviceString isEqualToString:@"iPhone8,2"]) return @"iPhone 6s Plus";
if ([deviceString isEqualToString:@"iPod1,1"]) return @"iPod Touch 1G";
if ([deviceString isEqualToString:@"iPod2,1"]) return @"iPod Touch 2G";
if ([deviceString isEqualToString:@"iPod3,1"]) return @"iPod Touch 3G";
if ([deviceString isEqualToString:@"iPod4,1"]) return @"iPod Touch 4G";
if ([deviceString isEqualToString:@"iPad1,1"]) return @"iPad";
if ([deviceString isEqualToString:@"iPad2,1"]) return @"iPad 2 (WiFi)";
if ([deviceString isEqualToString:@"iPad2,2"]) return @"iPad 2 (GSM)";
if ([deviceString isEqualToString:@"iPad2,3"]) return @"iPad 2 (CDMA)";
if ([deviceString isEqualToString:@"iPad3,4"]) return @"iPad 4 (WiFi)";
if ([deviceString isEqualToString:@"i386"]) return @"Simulator";
if ([deviceString isEqualToString:@"x86_64"]) return @"Simulator";
return deviceString;
}
-
iPhone 7,2是6,7,1是6Plus
这个方案还不是很确定, 如果我说的有问题, 欢迎来纠错, 谢谢
补充一下, 不管上一页有没有设置preView, 只要下一页的webView打开了allowsLinkPreview属性, 也会导致问题机型的崩溃
